1. Material Case & FibaRoll and FibaGel product overview
The improved physical protection and weather proofing of insulation materials is
necessary to improve the life of the insulation system and to minimize the risk from
corrosion under insulation (CUI). Existing methods and materials suffer greatly from
physical damage both during installation and during service allowing moisture ingress
at seams and terminations. Once the insulation becomes wet corrosion will cause CUI
leading to frequent maintenance, increased downtime and environmental damage.
FibaRoll has been used as an alternative for metal jacketing and mastics to protect
insulation material from water and corrosive liquids and thus minimizing the chances
of corrosion under insulation. The features that make it suitable for this application
are that it is mechanically strong, seamless, waterproof, flexible, can be coloured,
excellent chemical resistance and fire retardant.
FibaRoll is technically known as a fully composed „pre-preg‟ and when cured is a glass
re-inforced plastic composite also known as GRP. In its uncured state FibaRoll is a
soft, malleable, sheet material. It is supplied between two barrier films and when the
bottom surface is stripped it reveals a tacky surface that readily sticks to a wide

variety of surfaces. The top film is kept on (unless spiral wrapping) whilst the
material fully cures to give a hard, abrasion resistant/smooth and tough finish.
FibaRoll is supplied with the top surface outermost on the roll and should not be
applied back to front as there is a protective „veil‟ near the top surface, which aids
chemical resistance and weathering.
FibaRoll is supplied on rolls wrapped in a black UV blocking bag to exclude any light.
The roll core is supported at each end to prevent flat spots developing during
storage. The storage bags are double ended allowing removal from either end.
FibaRoll can be cut using a modelling knife or scissors however please remember to
keep the cut pieces out of daylight prior to application.
A typical construction of FibaRoll is shown below. The veil is of chemical resistant
glass and ensures excellent weathering and performance in immersion conditions.

The barrier films help to reduce styrene vapour escaping, helping to ensure a safe
and acceptable working environment.
Weathering and UV performance is good for all products with an expected resin
weight loss of 1-2% over 10 years. The construction of FibaRoll includes a non-woven
glass tissue on the top surface, which provides excellent weathering performance and
chemical resistance. In addition the construction lends itself to being re-coated with
a resin system which may be necessary after 10-15 years giving the system a life span
well over 25 years.
FibaGel is supplied in 2.5 kgs cans and is essentially the same base resin used in
FibaRoll. These resins are used as primers, fillers or as coatings.
2. Recommended FibaRoll and FibaGel products for insulation protection
applications
FibaRoll FR M1– Fire Retardant Low Smoke
FibaRoll FR M1 has been developed to have good fire and smoke performance and has
been independently tested for fire to Class 1 BS476 part 7 (Warrington Fire
Research, UK) M1 NFP92-501 Epiradiateur Test and to Class 1 ASTM E84 (Omega
Point labs, USA). FibaRoll FR has also been tested and passed the International
Maritime Organisation‟s fire and smoke test and has therefore been accepted by
Lloyds for use at sea (Warrington Fire Research).
This grade combines fire performance with good chemical resistance and excellent
mechanical properties. This product has been used to protect insulation on vessels,
vessel tops, pipelines and a wide variety of applications within refineries and chemical
plants. FibaRoll FR M1 has a maximum operating temperature of 100C with peaks up
to 160C.
Please refer to specific data sheets for full information on the physical properties of
each grade. All physical and chemical resistance properties quoted in the data sheets
refer to fully cured FibaRoll products.
FibaRoll requires Ultra Violet (UV) light (wavelength 360 – 420 nm) to cure.
For applications where natural daylight is very low or non-existent a suitable artificial
light source (contact us for details) is required to cure the material.
Both FibaRoll and FibaGel products have a standard colour range of natural, white and
grey however other colours are available but there are minimum order requirements,
please contact us for details.
Shelf life – FibaRoll FR M1 - 6 months from date of manufacture.

FibaRoll is available in three standard thickness‟ 1000 microns, 1500 microns and
2000 microns.
FibaGel Material and Grades
FibaGel can be used as a primer to improve adhesion to steel terminations.
FibaGel has two curing mechanisms namely by UV light as per the FibaRoll or „cold
cure‟ (CC) method, which uses the addition of a catalyst which gives a chemical
reaction cure. The FibaGel UV is cured as per the FibaRoll by ultra violet light and
subsequently the cure time is light dependent. On a sunny day the cure times for thin
applications can be as little as 10 minutes. The cold cure (CC) uses the addition of a
catalyst that must be mixed into the gel resin and this gives a cure time of 30-45
minutes dependent on temperature.
All grades are also available in a standard viscosity or a low viscosity (LV) version that
can be brush / roller applied.
FibaGel FR UV or CC (Cold Cure)
This is our standard viscosity, light curing or chemical curing, priming and filler
material manufactured from a complimentary resin system as FibaRoll. This material
can painted on, rollered on or trowelled into place. This is used when the substrate
profile is coarser, for example concrete or corroded pipe work. This is supplied in 2.5
kgs can and the FibaGel UV is light sensitive therefore when not in use replace the
lid. The FibaGel CC grade requires the addition of a supplied catalyst and this must
be fully stirred in.
Shelf life - FibaGel FR UV - 6 months from date of manufacture.
FibaGel FR Low Viscosity (LV) UV or CC (Chemical Cure)
This is a low viscosity, light curing or chemical curing, priming and coating material
manufactured from a complimentary resin system to FibaRoll. This material can be
painted into place. This is supplied in 2.5 kgs can and the FibaGel UV LV is light
sensitive therefore when not in use replace the lid. The FibaGel CC LV grade requires
the addition of a supplied catalyst and this must be fully stirred in.
FibaRoll and FibaGel products can be over-painted. Once they have fully cured lightly
abrade and apply a coating.
Shelf life - FibaGel FR LV - 6 months from date of manufacture.

Storage conditions
FibaRoll and FibaGel products should be stored inside in cool dry and well ventilated
conditions away from direct sunlight with temperatures not greater than 25 oC in its
original packaging. FibaRoll must be supported at all times and kept horizontal at all
times.
For extended over-seas container travel were the expected temperatures are likely
to be above 35-40 oC for long periods we would recommend a refrigerated container.
3.0 Surface preparation procedures
New insulation materials by their nature require no preparation however the common
forms of insulation materials like foamglass, mineral wool or PUR / PIR can be
supplied with a foil face lining material. This is obligatory on vertical surfaces such as
tank walls and a beneficial addition on pipework. Foil faced materials aid FibaRoll
applications because the foil linings can be cleaned of dust and debris easily and this
will help adhesion strengths. The foil linings also assist with the adjustment of
uncured FibaRoll during application as you can peel back the FibaRoll without reducing
its tack / stickiness greatly.
All insulation materials must be closely inspected prior to the application for damage,
areas of dampness and particularly with mineral wool areas of low density.
With mineral wool we would prefer to utilise densities above 125 kgm3 as these
densities provide a firmer substrate to wrap onto.
As FibaRoll is a soft mouldable sheet material it is worth noting that it will take the
shape of the substrate being applied onto.
Required Tools – Cutting environment
Some sharp, modeling style knives (Stanley type) – This will ensure clean cut edges.
Some clean soft cloths – This will aid smoothing the FibaRoll down, as it is applied, to
ensure that air is excluded and that the FibaRoll is „tight‟ to the substrate.
Some flat seam rollers – These are commonly used in wall papering and are important
as all seams need to be firmly rollered down.
Some good scissors – These can be used for detail work when cutting templates and
FibaRoll etc.
Disposable gloves – These will help to prevent you‟re hands getting sticky and will also
help keep application work clean.
A metal ruler preferably a one metre one, a metal set square to ensure 90o angles and
a set of dividers for circular shapes i.e. end caps etc.

Some applications may require a metal halide lamp plus protective glasses.
The best areas in which to cut FibaRoll should be well ventilated and well lit with a
non UV containing light source (household light bulbs and fluorescent tubes are OK).
A steel topped table is highly recommended with a FibaRoll stand at one end so that
the material can be run out easily whilst being suspended and cut to length. We
recommend that the material is run out with the yellow film uppermost. This will help
reduce the incidence of wrinkles and laminations. When cut, Fibaroll should be either
carried flat to the application area or rolled onto a round core (as supplied).This will
ensure that there are as few creases or folds in the material as possible. The
material should be protected from any UV light sources until just prior to application
and the open ended black bags supplied are useful in this.
4.0 Application methods and schedule
a) Straight Lengths
There are two standard jointing methods for a “cigarette wrap”. The joints can be
overlapped or, as described below, use a 100 mm strip and butt together the joining
strips on top.
The application starts at either 2 to 3 o‟clock on the pipe / ducting and continues
underneath the pipe / ducting stripping the bottom film as the application
progresses. Air can be smoothed out by using a cloth to smooth the FibaRoll onto the
surface, just as in hanging wallpaper. The top film is kept in place apart from the area
of the overlap. The horizontal overlap points downwards so that water does not run
into the joint. Hand pressure with a cloth or a hand roller must be used to consolidate
the material at the overlap.
The vertical overlap to the next sheet is achieved by first peeling back the top film
from the area of the overlap only with knife or scissors. Then the new sheet is
applied over the revealed area, the peeled film is brought back over the joint and

pressure is applied to the joint by using a roller. It is sensible to stagger the
horizontal joints where possible.
FibaGel may be required to seal any joints, which do not look watertight.
The top film is removed only when curing has completed.

Joint using a 100 mm strip of FibaRoll below a Butt joint
The underlap strip is placed at appropriate distances along the pipe so that the
sheets of FibaRoll meet on top of the strips and are butted together. The underlap
strips are overlapped themselves and the top film removed. The strongest FibaRoll
joint is „wet‟ FibaRoll onto „wet‟ FibaRoll. If a strip cures and the top film was
removed then this rough surface is an adequate surface to apply more FibaRoll onto
with further surface preparation. Each joint and seam must be rolled down to ensure
that it is closed.

b) Bends/Elbows
The two preferred methods are
to cut a “lobster back” or strips.
The application is started at the
lowest point of the bend. Cut
strips of FibaRoll are applied to
the insulated pipe where the
„lobster back‟ pieces are to be
joined. The top film is stripped
from these strips and the „lobster
back‟ pieces are applied directly
onto them using hand pressure.
The „lobster back‟ pieces are butt
joined together and the seams
smoothed with a cloth or a hand
roller.
After application, FibaGel should
be used if required to seal any
joints.
c) Tees
First, cut two strips to go below the seams at the collar area to cover the junction between
the two pipes. This should be at least 30mm wide and cut in two allowing for a vertical overlap.

Apply these strips as shown below and remove the top film. Remove the top film from the
collar. Cut the pipe sections as illustrated to cover the pipes and overlap the collar by at least
50mm if possible.
After application use FibaGel to seal any joints if necessary.
d) Reducers
In most cases, it will be necessary to cut strips wider at one end than the other to
follow the dimensions of the reducer although it can be possible to cut a cone shape.
overlap each other for 20mm at the underside of the pipe.
Inspect carefully and apply FibaGel to any areas not completely closed.
Note: Where there are small pipes, instruments or trace heating lines etc,
entering/protruding from the insulation system this treatment may be
cumbersome in which case a combination of FibaGel and small strips of FibaRoll
will work better.

f) Insulation protection for storage vessels and tanks
The protection of insulation materials for large vessels and tanks requires a slightly
different application technique. With this method „sheets‟ of FibaRoll are joined
together to make a seamless protective covering.
We have two basic joining seams; overlap jointing and a FibaRoll strip below two
FibaRoll sheets butt jointed on top.
Example of butt jointed FibaRoll sheets on top of 100 mm under-lap strips.
A measured a cut strip of 100 mm wide FibaRoll is applied to the insulation substrate
in a position where the seam is going to be, and the top film is stripped off. Before
the FibaRoll strip has cured a sheet of FibaRoll is applied onto the insulation ensuring
that 50 mm of the edge is on our already applied strip. The next FibaRoll sheet is
applied next to the first also ensuring that the two sheet edges butt together on top
of or strip. This seam area must be rollered down or smoothed with a clean cloth to
make sure the seam is closed and weather tight.

Repairing Procedure for wrinkle occurred from roll and application
If the above wrinkle is left without repair, mold may occur in the wrinkle.air
After r
1. Cut the film of wrinkle by knife or by careful sanding with an appropriate grade of
sand paper
2. Remove the dust and apply the Fibagel by spatula, smoothing and filling as you go.
3. Cure the gel
Examples of overlap Jointing
Overlap jointing is where the edge of an applied sheet is overlapped by a
recommended minimum of 50 mm of FibaRoll. We further recommend that the
overlap material is overlapped onto uncured FibaRoll. To perform this method it is
necessary to peel back the top film to create a FibaRoll / FibaRoll bond. The top film
can be brought back over and this seam rollered down as per the diagram below.
Vertical overlap joint
It may be necessary to use some sellotape to hold the top film in place while the
FibaRoll is curing as strong winds can get under the film and strip it before full curing

has taken place. Please be aware that a double layer of FibaRoll will require longer to
fully cure.
Horizontal overlap joint
Minimum 50 mm overlap
Vertical overlap joint
To achieve these water shed vertical joints, care must be taken to plan the
application. It will be necessary to start at the bottom of the tank wall and work
upwards. Any seam that does not pass a visual inspection can be sealed with FibaGel
UV.
On rounded surfaces like the dome tops of tanks the jointing methods are the same
although the shapes are obviously different. Care must be taken with curved cut
pieces of FibaRoll that the joints are a minimum 50 mm to ensure a strong, sealed
joint.
Typical complete curing times in good daylight for FibaRoll is 1-3 hours however
curing times can vary depending on the light levels, material thickness and should
be assessed during the day (see application conditions).
If required, seams can be further sealed with an application of FibaGel.
The top film should be removed only when the FibaRoll is fully cured. In practice the
top film should not be removed for at least 6 hours of daylight after application.
FibaRoll and FibaGel products can be over-painted. Once they have fully cured lightly
abrade and apply a coating.

c. FibaRoll curing period.
d. Inspection of the application with a FibaGel application onto the seams and areas

5.0 Terminations, expansion joints and cladding support
Terminations from the insulation are very important. A poor termination can let the
rain / moisture into an insulation system and potentially cause serious damage.
However where movement is expected within the insulation system during operation
(thermal expansion and contraction) or during commissioning, then a flexible
termination must be used.
All cladding systems require support and FibaRoll is no different. We have includes a
couple of techniques within our technical drawings. Wherever possible we recommend
that this issue is discussed at the design stages of the equipment so that engineering
solutions such a stiffener rings and support bars are included.

If FibaRoll is required to terminate onto concrete from an insulation system (i.e. the
concrete plinths at the base of storage tanks) then the concrete must have a
moisture content of a less than 5%, have the correct surface preparation (i.e. needle
gun or similar to remove the fines and laitance at the surface) and then a primer coat
of FibaGel. Annular ring movement must be accommodated due to tank filling and
emptying therefore we recommend that the Fibaroll is bonded well to the insulated
tanks wall and to the vertical or sloping face of the tank plinth. The „free‟ area of the
horizontal surface should allow for any movement and reduce any stress areas.
For terminations where there is expected movement there is a drawing 1) that shows
the termination techniques for good access and where access is restricted.
A second pieces / pieces‟s of FibaRoll are then applied
onto the first piece.

circumferentially wrapped and overlapped onto
itself to fully close the seam.
A third piece is circumfrencially
wrapped and bonded onto the
steel pipe thus closing the seam
giving a very strong termination.

6.0 Service temperature, design and curing
Insulation systems can be split between hot and cold service temperatures and each
area holds its own challenges and demands.
With all insulation systems one must consider the vapour barrier issues and moisture
penetrating through the cladding material and affecting the efficiency of the
insulation design. Mastic and scrim designs are difficult to apply and are easily
damaged both during installation and service. Aluminum foil vapour barriers especially
PAP foil (polyester / Al / polyester film) are easy to apply and with the PAP foil
option, are tough and difficult to pierce.
The chosen cladding system, like FibaRoll must be tough and flexible to withstand
mechanical damage i.e. foot traffic that could damage both the cladding and the
vapour barrier.
With both hot and cold systems the potential for water ingress at terminations can
be especially high. With this in mind some clients prefer to have at the strategic
points within the insulation system some drain holes that allow any water or vapour to
exit.
FibaRoll should be cured at the earliest opportunity to ensure that in the period
between application and curing, the environmental conditions do not change
significantly. This also applies to indoor applications where the uses of UV lamps are
required. The best advice is to apply and cure as soon as possible.
We have a number of cure options that should suit most light environments, please
contact us for advice.
7.0 Application Conditions
The weather should be dry with the ambient temperature ideally 5 oC above the dew
point and the substrate 3oC above. Light levels have to be assessed and if judged to
be too low then appropriate lamps must be used, please contact FTi for full details.
FibaRoll and FibaGel materials can not be applied in wet conditions as the moisture
affects the curing mechanisms. In dry conditions FibaRoll can be applied up to 65 oC
and down to –15 oC however any applications in extremes of conditions should be
discussed with FTi.
To assess cure times vs light levels there is a simple daily test that can give a good
indication of curing times in prevailing light levels. A small sample patch is taken and
cut in two; these pieces are stuck together as you would an overlap joint to create a
double thickness of FibaRoll. This test piece is placed in an area that has the poorest

light levels (using clear sellotape/scotch tape) and at suitable time intervals (30
minutes), checked by attempting to scratch the inside surface with a fingernail.
When you can no longer scratch the surface of the material it is fully cured. This is
your cure time for an overlap joint in an area of the least available UV light in those
prevailing light conditions. To provide a safety margin it is recommended to expose
the system to double the minimum cure time achieved in this test procedure.
Any areas that are in shadow, for example the bottom of a pipe in a trench, often
require the use of some reflective material such as aluminum baking foil to reflect
the light (natural or otherwise) into these areas. Where light levels are assessed to
be high and the material is curing too fast then temporary shading is required.
Training requirements
To ensure confidence in FibaRoll applications we require that only trained personnel
who are on our „FibaRoll trained applicator‟ register can apply FibaRoll and FibaGel
products. Training plus applicator exams can be arranged by contacting FTi.
8.0 Health, Safety and the Environment.
Both FibaRoll and FibaGel contain Styrene and this is the chemical that one can smell
when dealing with these materials. The emissions measured from FTi‟s materials are
well within the prescribed OEL levels. However some people find the smell unpleasant
and in confined spaces or areas with little air circulation it is necessary that
extraction be used and that there is a free flow of fresh air. In confined spaces we
further recommend that concentrations of styrene are monitored.
Both FibaGel and FibaRoll materials are sticky and applicators are advised to wear
gloves when handling.
Any waste materials should be cured off fully and this then becomes inert and can be
disposed of as non-hazardous materials.
When using lamps as a curing tool it is necessary to use appropriate protective
glasses to reduce glare.
9.0 Application integrity testing, quality, trouble shooting and repair.
If you find that the tackiness of the FibaRoll is reduced or the sheet begins to
„stiffen‟ then the sheet has been exposed to UV light and extra light protection is
required.
Whitening of the FibaRoll indicates that some form of inhibition of the curing
mechanism has taken place. This may be due to the top film being stripped too soon
or high levels of moisture present due to wet conditions or high humidity. Unless
extreme this whitening does not effect the physical properties unduly, however it can
be unsightly and should be avoided by keeping the top film on until fully cured or the

atmospheric conditions improve. We recommend that FibaRoll is cured as soon as
possible after application to reduce the incidence of whitening. Please refer to our
„method supplement‟ when using Metal Halide curing lamps.
If an area is required to be opened for inspection purposes FibaRoll can be entered
by drilling a hole (either power or hand tool) and using snips to create a larger
opening. This opening can be re-sealed by abrading at least 50mm around the hole,
removing the dust and applying a FibaRoll patch. The same technique can be used to
repair damaged areas.
Fully cured FibaRoll should have the top film removed as this film can, if left in a UV
environment become friable and difficult to peel. Although this is not a technical
issue it can look unsightly. As a registered BS EN ISO 9001 : 2000 (cert. No. 21354) company we have full
trace-ability and would strongly recommend that on all applications the batch
numbers and product codes should be noted down to comply with your quality
systems.
FibaRoll repair and refurbishment: It is likely that some degradation may occur
sometime after 10 years and can be refurbished easily with a further FibaGel coat
during normal maintenance.
