Protim Frameguard® - Koppers Preserved Timber

Protim Frameguard® is a combined flame retardant and preservative treatment system developed to reduce flame spread in framing timbers & plywood’s during construction and to impart preservative protection against fungal decay and insect attack to Use Class 2 (60 years desired service life, in accordance with BS 8417:2011 Preservation of Wood - Code of Practice.)


Protim Frameguard® has been tested by Building Research Establishment (BRE) in accordance with BS 476 Part 7, the UKTFA ‘FR Build’ Scheme and complies with the NHBC preservation requirements for framing timbers embodied in Chapters 2.3 and 6.2 of the 2006 edition of NHBC Standards.



Why Protim Frameguard®?

There is an ongoing desire to enhance confidence in timber frame as a secure and safe construction system. Fire risk management during the construction phase requires a matrix management approach. Fire retardant treatment protection of timber framing can provide an important, additional element to this management matrix. Fire retardant treatment can help reduce the rate of flame spread on the treated timber. This allows more time for other risk management measures to be effective and so minimize the consequences of a fire. Fire retardant treatment does not stop wood from burning altogether and must not be relied upon as the sole means of managing fire risk on timber frame construction sites.


Why is Protim Frameguard® different?

Fire retardant treated wood products have been sold in the UK for years and the market is well established. The traditional fire retardant market is based on the use of high pressure impregnation processes, followed by kiln drying prior to use. Protim Frameguard is a new integrated process that offers an economical approach, providing the benefit of fire retardant protection for wood products during construction and long lasting preservative protection.


How is Protim Frameguard® applied?

The Protim Frameguard treatment system can be applied in existing low pressure treatment plants with minimal engineering modification. Treatment solution is supplied by bulk tanker in readyto- use form. Application is by cycles and processes broadly similar to those already in use. Solution uptakes per m3 timber will be of a similar order of magnitude as before, with no significant lasting impact on timber moisture content.
