Due to our policy of continued improvement Kestrel Aluminium Systems reserve the right to alter details and specifications without prior notice.

General guidelines for cutting and bar preparation:

For further reading on cutting, preparation and workmanship please refer to BS 8118: Part 2: 1991.

Storage and transportation:

Store aluminium in a dry place, clear of the ground. Avoid contact with other metals and with materials such as cement and damp timber.

Protect aluminium extrusion surfaces with low tack removable tapes while danger of damage exists. Pack aluminium during transportation to avoid mechanical damage, abrasion and contact by agents liable to cause surface corrosion or staining.

Fabrication tolerance:

See corresponding sheets for each section type

Marking out:

Fine scribing lines must not be used on critically stressed ares of thin material. Where subsequent welding is involved paint, chalk, graphite or other marking materials likely to contaminate must not be used.

Cutting:

Cutting can be by circular saw or band saw and both must have a tooth form and pitch to suite the thickness of the material to be cut. Cut edges should be smooth, square and free from burrs, distortion and other irregularities. Care must be taken to avoid the use of tools contaminated by other metals, particulary copper or brass. Great care must be taken when working with mitred end cuts to avoid impact damage to ends (ideally bars should not be stored or transported vertically without corner protection).

Drilling, punching and preparation:

Holes can be made by either drilling, drilling and reaming or by punching. Drill holes should be smooth and free from burrs, distortion and other irregularities. Drainage slots must be of the correct diameter and length and positioned correctly. At all times prepared bars should be free from general debris and cutting/drilling swarf.

Assembly:

All joint surfaces should be free of dirt,grease and cutting/drilling debris. All joints shall be sealed against the entry of water by use of a high quality silicone sealant. NB Small gap joint sealant is NOT to be used on painted material - only anodised or mill finish profile. Be careful not to handle or transport frames in such a way as to disturb or open joints by excessive movement or bending of frames etc.

Installation - Basic guidelines


7.05.0101.10.08Sheet 1



Installation

Installation should be to an agreed method statement and approved drawings using suitable erection methods and equipment and CWCT certified site teams (both for fixing teams and site supervisors/managers).

Working drawings must show the following;

Setting out dimensions and levels.Details of curtain wall interfaces with building fabric & special information i.e. maximum and minimum tolerances.All fixing details and packing/isolating requirements, bolt and fixings descriptions.Full glass and glazing specification.

Tolerances

We recommend the following deviation (CWCT) limits;

Line: +/-2mm per story or bay width. +/- 5mm overall.Level: +/-2mm per story or bay width. +/- 5mm overall.Plumb: +/-2mm per story or bay width. +/- 5mm overall.Plane: +/-2mm per story or bay width. +/- 5mm overall.

This level of accuracy requires accurate measuring instruments. I.e. Single to two storey simple elevations - plumb bob and calibrated levels may be used. Two storey and above, complex elevations - dumpy level or theodolite should be used in conjunction with main contractors setting out.

Sealing

The Kestrel Low Rise Curtain Wall is a performance system, and is drained, ventilated and pressure equalised. To ensure performance ALL internal seals i.e. basic grid, internal gasket joints and zone sealing blocks MUST be properly completed to achieve an AIRTIGHT seal. The internal seals are the most critical to correct functioning of the system.

Use sealants as described in the manual and use required seal primers in accordance with the manufacturer's recommendations.


Installation - Basic guidelines


7.05.0101.10.08Sheet 2



Sealing continued

Where dynamic movement is required - use LOW modulus silicone. For all other seals use HIGH modulus silicone.

Silicone sealant is water repellent. Never attempt to erect and seal the components of the system in wet weather or when individual components are wet.

If fits are in doubt - check with a dry run first.

Always clean off excess silicone sealant at the time of completing any joints. Cutting away later may pull sealant out of joints - joints are thus no longer airtight!

Do not flex or twist sealed joints as this may also break the seal.

Glazing

Glazing and glass specification should be in accordance with the requirements of BS 6262 and Document N.

Setting blocks should be placed approximately 100mm in from each end of the transom - position blocks to avoid covering the drainage slots in the pressure plate.

Gaskets - internal or external - DO NOT STRETCH to fit, always allow extra gasket in length, fit and seal together under slight compression.

Glass calculations allow for a constant 6.00mm air-gap around the unit. Always centralise the glass within the grid. Do not reduce the 6mm air-gap especially at bottom of unit.
