DearSasha

Further to your e mail below and the type approval application from Kingspan, please find attached an electronic copy of the type approval compliance declaration along with the three documents which should accompany the type approval certificate. Because of the limited room on the form itself, the relevant issues have been summarised on the separate summary document. The draft copy of this has been forwarded previously to Phil Harrison at LABC and Andrew Pack at Kingspan and, following their comments, should now be ready for formal issue

Please let me know if you should have any queries.

Many thanks for your assistance

Kind Regards

David Jones

System Approval - External Walls of Rainscreen Cladding Incorporatinq Kingspan Kooltherm K15 Insulation Board

Summary of the System and the Main Issues Considered

Overview

Kooltherm K15 is a rigid phenolic insulation board incorporating foil composite facings. It is intended for use as a thermal insulation layer to be applied to the external face of new and existing masonry or metal framed walls as part of a rainscreen cladding system.

Under this system approval certificate, Kingspan K15 is the only specifically defined element within the system, the inner substrate and the outer rainscreen cladding layer being variables which can be selected on the basis of the criteria set out below to meet the specific requirements of the project.

The System

The overall wall construction must reflect standard design details as shown in Figures 1, 2 and 3 of Kingspan technical literature ’Kooltberm K15 Rah~screen Board’, Eighth Issue November 2008 The standard forms of construction contained therein and as considered under this system approval would consist of:

An inner substrate of reinforced concrete, masonry, or hollow metal-framed walling forming part of the building superstructure.

A continuous layer of Kingspan Kooltherm K15 rainscreen insulation board restrained to the outer face of the inner substrate with a minimum of nine proprietary insulation fasteners per board and with rainscreen cladding tape applied to joints.

A ventilated residual airspace of at least 50mm between the outer face of the insulation and the inner face of the cladding.

A rainscreen cladding weathering layer structurally fixed back to the inner substrate using proprietary fixing brackets reflecting the manufacturers recommendations and the requirements of the structural design.

When used as part of an overall wall construction in line with the above and reflecting the standards set out below, Kooltherm K15 can be deemed acceptable as the insulation element of the system subject to any limits set out or referred to within this certificate:

BS 5628: Parts 1-3 2005, Code of practice for use of masonry, or Reinforced Concrete: BS 61 I 0~1:1997 Structural use of concrete, Code of practice for design and construction1, or Loadbearing Metal Framed Walling:

Revision 1 3 Match 2008

HBC00000048_0004 HBC00000048/4

External Weathering Leaf:

Rainscreen Cladding: !3S 8200 1985, Code of practice for design of non-loadbeanng external vertical enclosures of buildings. BS 8399-2:1997 Loading for buildings Code of practice for wind loads. BS EN 1991 I-4: 2005, Actions on Structures - General Actions - Wind Actions. BS 5080 Structural fixb~gs in concrete and masonry; Parl 1:1993 Metbod of test for tensile Ioadings; Part 2 1986; Method for determlnation of resistance to loading In shem. In all cases, structural stability of the whole system must be assessed on a project-specific basis by a structural engineer.

Key Parts of the Building Regulations Considered:

Requirement A1 - Structural Stability

K15 is capable of carrying its own self-weight when fixed in accordance with the manufacturers recommendations, but otherwise cannot be considered to contribute towards the structural stability of the building in any way. Detailing should ensure that any wind or other Ioadings are transferred to the structural frame/wall as appropriate.

Requirement B - Fire Safety Considerations

K15 has been tested in accordance with:

BS8414-1; 2002 (Fire performance of external cladding systems. Test methods for non- Ioadbeadng external cladding systems applied to the face of a building), BS EN 1364-1 ; 1999 (Fire resistance tests for non-loadbearing elements - walls), BS476-6; 1989 (Fire tests on building materials and structures. Method of test for fire propogafion for products) BS476-7; 1997 (Fire tests on building materials and structures. Method of test to determine the classification of the surface spread of flame of products)

From the results, it can be considered as a material of limited combustibility and meets the criteria for Class 0 classification for surface spread of flame.

¯ Requirement B3; Internal Fire Spread

A series of cavity barriers must be detailed on a project-specific basis to prevent fire spread around compartment floors or walls and to observe undivided cavity limits as set out in Table 13 of Approved Document B Volume 2; 2006. The performance of the barriers and the method of fixing must ensure that they will remain in place and maintain fire resistance for at least 30 minutes, or match the period set for the compartment wall/floor which they abut (whichever is greater).

¯ Requirement B4; External Fire Spread

Since K15 can be considered a material of limited combustibility, it is suitable for use in all situations shown on Diagram 40 of Approved Document B Volume 2, including those parts of a building more than 18m above the ground. In the latter circumstances, the cladding system and the substrate to which the insulation is applied must also meet the requirement for limited combustibility. Where the substrate is a metal-framed wall system rather than masonry or concrete, a non-combustible lining board must be specified to the external face of the metal frame wall (eg, calcium silicate board or similar performing).

3 Mamh 2008

HBC00000048_0005 HBC00000048/5

Where an elevation falls within 1000mm of a relevant boundary as defined in the Approved Documents to Part B, K15 as a class 0 material will not have a detrimental effect of the performance of the wall and can be disregarded when assessing the extent of unprotected areas, subject to the other elements of the wall meeting the appropriate standard.

Requirement C1:

Resistance to Moisture Penetration Surface and Interstitial Condensation

With a clear cavity of at least 50mm maintained between the outer face of the insulation and the inner face of the rainscreen cladding system, K15 wiJl not convey moisture to the inner substrate irrespective of the height of the building or the level of exposure of the site.

Surface and interstitial Condensation

Provided that the thermal transmittance (u-value) of the wall does not exceed 0.7 Wm2K at any point (in line with guidance from Approved Documents relating to Requirement L1), and that all junctions and interfaces are detailed to avoid thermal bridging* then Kooltherm K15 would be expected to adequately limit both interstitial and surface condensation in walls.

Requirement L1 - Thermal Performance

For the purposes of calculating u-values in order to demonstrate performance under Requirement L1, Kooltherm K15 can be taken to have thermal conductivity values as set out below. The stated performance is supported by a current agrement certificate.

~Board Thickness (mm) Thermal Conductivity (W/m.K) 4 [24 or under 0.024 | 125 - 44 0.023

! 145 or over 0.021

Regulation 7 - Materials and Workmanship

Independent test data has shown Kooltherm K15 to be suitable for the purpose for which it is proposed. When installed in accordance with manufacturers recommendations, no short or long term maintenance is required and the board can be expected to have a lifespan equal to that of the structure in which it is incorporated.

Note: LABC Type Approval is limited in scope to those issues which are relevant to the requirements of the Building Regulations as defined in this document and any other supporting documents referred to on the certificate. Any matters falling outside the scope of the regulations will not have been considered as part of the type approval process
