Industrially applied impregnation procedures or coating solutions could be used when ever fire protection is necessary for timber cladding.
Impregnation can be more effective when compared to fire retardant surface finishes. The essential factors to take into consideration when specifying and choosing are: availability and price; product performance and assurance; toughness and upkeep; quality of application.
\’Quick fix\’ coating products may be used due to tight work deadlines and schedules.
The cost of brush or spray applied covering systems might be less costly compared to the initial price of pressure impregnated fire resistant treated timber. In the long term impregnation methods offer you a much more affordable solution since the maintenance generally vital for fire retardant surface finishes is larger.
After extensive exploration carried out by the independent fire test house Exova Warringtonfire, key industry manufacturers have declined the hard to rely on density classification system as used by various fireproof treated timber dealers in great britain. This specific system is based primarily on the actual density associated with the timber before fire resistant treatment options and presumes comparable density species will demand the identical treatment amounts. Which is false.
Species specific assessment has to be administered. In order to achieve the appropriate – and safe – level of fire protection related density species at the comparable thickness require totally different ranges of fire resistant retention in the actual wood.
Exova Warringtonfire supports specifiers and Building Control individuals to employ a species specific Classification Report system via 3rd party test houses.
Lonza Wood Protection has invested in a large selection of individual impartial Classification Reports in order to cover timber types, timber thicknesses and end use applications with regard to each of its tested fire retardant impregnation treatment solutions – DRICON and NON-COM Exterior.
Enjoying more than twenty-five years of constant certification, Dricon carries on to be the only BBA-approved fire retardant for wood. The only National House Building Council (NHBC) approved fire resistant treatment solution for external cladding timbers is NON-COM Exterior.
Profiles of pressure treated fire resistant wooden cladding are currently readily available from a variety of top rated timber suppliers.
