Maintenance

Exterior applications

The maintenance interval for exterior timber cladding treated with NORFLAM® W313 is up to 7 to 10 years, depending on the structure, weather exposure and treatment method.

In outdoor applications, wood cladding that was industrially, off-site or on-site treated according to the manufacturer's instructions will require re-treatment after 7 to 10 years. The re-treatment must be done using the same flame retardant originally used to treat the wood product.

Interior applications

In indoor use, wood cladding that was industrially, off-site or on-site treated according to the manufacturer's instructions will maintain fire protection properties throughout its life cycle unless the surfaces are mechanically damaged.

For more information about NORFLAM® W313 maintenance and on-site treatment instructions, see the Technical datasheet or contact Treet's technical service.

Why choose NORFLAM® W313

NORFLAM® W313 is a bio-based, water-borne, pH-neutral, low-VOC flame retardant for wooden construction products. It provides a Euroclass D-s1, d0 reaction to fire performance with a clear or semi-translucent toned finish.

NORFLAM® W313 is a one-product solution based on the unique, certified NORFLAM® technology developed by Treet.

NORFLAM® W313 flame retardant is typically used for fire protection of facade cladding, and interior wood cladding and panelling made of thermally modified timber.
