Non-Com Exterior


 

 

 


NON-COM Exterior is a polymer resin fire retardant impregnation treatment fully in line with the National House Building Council (NHBC) standards for external timber cladding.

A commercially proven global brand, NON-COM Exterior is backed by extensive independent fire certification and more than 40 years of fire performance experience.

NON-COM Exterior fire retardant treated timbers for exterior or severe damp situations have a proven track record of reducing the growth of a fire and the effects of heat and smoke release to provide extra time for escape and damage limitation.

NON-COM Exterior is a Type 'LR' fire treatment that is very durable and does not require any maintenance throughout the life of the build.


A wide range of timber species can be treated to either Euroclass B or C as defined within EN 13501-1 to provide Building Regulation compliance to meet project requirements.
