fermacell® gypsum fibreboard

Description of Product

This is an assessment of fermacell® gypsum

fibreboards applied one layer each side for use

in non-habitable roof spaces for use in single

skin Spandrel Panels. The system achieves 60

minutes fire resistance and can be used to

assist in sound separation between dwellings.

fermacell is formed using recycled gypsum

from coal fired power stations and recycled

paper.

The system comprises a 15mm thick

fermacell® gypsum fireboard fixed with both

sides of timber frame manufactured by others

having 70 x 44mm minimum timber size.

Key Factors Assessed

Safety in case of Fire

Health, Hygiene and Environmental

Protection against noise

Validity

This certificate was first issued on 12th September 2019 and is valid until 12th September 2020

Issue Dated 12th September 2019

Certificate No: EWW1183

Fixing

Phosphate coated fermacell 3.9 x 40mm fermacell™ screws at 250mm centres.

Alternatively 48 x 10 x 1.5mm galvanised staples can be used for fixing at 200mm centres.

If 89 x 38mm timbers are used an 18mm board is required, fixing details are to be obtained from the fermacell technical

department.

fermacell board must be fixed to the small face of timber only. If nail plates are used on timber frame they must be a

minimum 1mm thick with minimum 8mm long nails fixed to each face of the timbers and CE marked to EN 14545:2008.

Joints

Standard sheeting joints are tight dry-butt joint. Gaps require fire mastic or 150mm cover strip of fermacell with 55mm

fermacell™ screws into each timber at 250mm centres and 55mm long skew fixings to connect panels (see fermacell

brochure for details.)

Fire resistance

The spandrel panel in effect forms a barrier in the concealed space which is non-loadbearing but will provide resistance to

penetration (integrity) and resistance to transfer of excessive heat (insulation) for a period of 62 minutes proven in test to BS

476: Part 22:1987 which exceeds the recommended 60 minutes in table A2 of Approved Document B.

Sound

fermacell® gypsum fireboard can be used with Robust Details Walls to conform to AD E. Panels are now part of Appendix A

in Robust Details as an accepted solution. The supporting blockwork should extend 300mm minimum above finished ceiling

level with the cavity wall closed with a proprietary cavity stop. The junction between the spandrel panel and supporting

blockwork is to be sealed with flexible or acoustic sealant or mounted on a layer of mineral wool.

Installation to be in strict accordance with manufacturer’s instructions, guides and recommendations.
