Too many contractors and builders are convinced that they are building with fireproof materials and are in accordance with the law because they bought a wood product that exhibits B-s1, d0 or SP-Fire 105.

Unfortunately, we must disappoint you if you have not checked the permanence of this fire resistance.

It is of no significance if the product is certified or classified for the current fire class if the impregnated wood panel or fire protection colour does not have certification for long lasting properties according to EN16755 alternatively CEN/TS 15912 DRF, -INT 1, -INT 2 samt EXT.

The latter EN 16755, -CEN/TS 15912 DRF EXT is a shell requirement if the product is approved for use in exterior environments or not, for example as facade cladding in multi-storey houses. Approval according to EN16755 DRF EXT must be shown in the type-approval certificate, which is the only way to confirm whether the product is approved or not.

Keep in mind that it is your responsibility as a builder and/or developer to document this very important feature, which is rarely written in regulatory text, but which is of vital importance for long-term function. Swedish National Board of Housing, Building and Planning's BBR manages the property by emphasizing "financially reasonable life expectancy".

Fireproof wood is about fire safety for you, your loved ones, economic values and security in our society.

Fireproof wood definitely does not concern unconditional empty promises, statements and praise, not about fire protection products with hygroscopic properties, not about fast delivery and low prices. A type approval certificate for EN 16755 or CEN/TS 15912 can never be replaced by SAK 3 (Fire Consultant) or equivalent opinion.

A fire protection impregnated wood panel is meant to protect against fire in the long term, not short-term.

A fire protection impregnated wood panel with fire protection not certified according to EN 16755 or CEN/TS 15912 DRF EXT is not a suitable product to use, and definitely not a fireproof investment as fire protection deteriorates and leaks over time.

There is a growing and sneaky problem for resident tenants and for the property owner who are expected to renovate the building's façade, as fire protection will disappear and in the worst cases will not meet the current fire requirements stated in the Swedish National Board of Housing, Building and Planning's BBR.

At worst, insurance companies can question the choice of the product and greatly reduce compensation to the property owner in case of damage.

Woodsafe PRO™ and Woodsafe Exterior WFX™ are safe to use and are third party certified according to 1 and 8 chapter 22 and 23 §§ Plan, and the Building Act (SFS 2010: 900) and 4 § 2 and 3 PBL and the Swedish National Board of Housing, Building and Planning's building regulations (BBR) 2:2, 5:231, 5:551, points 2, 3 and 4, 6:21 which includes resistance requirements EN 16755DRF EXT for construction work in class Br1

Woodsafe PRO™ is listed as HR (Humidity resistance) and Woodsafe Exterior WFX™ is listed as LR (Leach resistance) on the AWPA approval list for fire proof impregnated wood products. Woodsafe is the only manufacturer outside the UK certified according to the Wood Protection Association (WPA) as a WPA Benchmark Approved Treater.

Valuable advice to builders and above all to you as a developer:
Do not use wood panels as fire-treated without type-approval certificates for resistant characteristics.

This advice applies to both fireproof impregnation and fire protection.

If, however, decisions are made that the product or performance of a firewall that has not been certified with durable properties is a lottery in terms of security, and a liability for major future maintenance costs, because you are well aware that products that have no durable properties need to be renewed and with short maintenance intervals.
