Fire Retardant Treatments
Because of the particular safety aspects of fire protection, we do recommend that you contact Arch directly to discuss your project requirements.
Arch offers a choice of proven fire retardant treatments depending on the timber's eventual end use. DRICON is the only BBA certified fire retardant treatment for timber and can be specified for interior and weather protected exterior situations. NON-COM Exterior has been specified for over 25 years for exterior and severe damp end use situations. VACSOL FR is a new fire retardant protection specifically for timber frame components during the construction phase of new build projects.
