QUESTIONIs tretford suitable for use on walls? ANSWERYes, tretford is ideal for vertical applications and can be installed as an acoustic wall covering on any clean, dry, smooth surface.
tretford meets this standard - a copy of the test report is available on request. Reference: 1993, Flame Retardant Specialists Ltd., Bray, Co. Wicklow, Ireland Reg. No. 189698 What is BS 476, Parts 6, 7 and 11, Class O? BS 476, Parts 6, 7 and 11 is the British Standard applicable to floorcoverings which are fixed to walls. Class O is the required rating. |
“These parts of BS476 specify a method test for measuring the lateral spread of flame along the surface of a specimen of a product oriented in the vertical position and a classification system based on the rate and extent of flame spread. It provides data suitable for comparing the performance of essentially flat material composites or assemblies which are used primarily as the exposed surface of walls or ceilings”.

Reference: 1994, Wira Testing Centre, BCTC Camraso, Leeds, UK.‘When the carpet is used as a wall covering, and in order to meet the relevant standard, it is necessary to ensure that the material is securely fixed to the wall surface, with a p.v.a. adhesive or similar non-flammable bonding agent, negating the oxygen gap behind the material. If fixed in this way, to the substrate that is also Class 1, then the total laminate can be considered as Class 0.
Installation
When installing tretford on walls with ribs running vertically, run full sheet along ceiling line to keep seam below eye level. Reference wall installation lists are available on request.
