Low Pressure preservatives provide long term protection against wood destroying fungi and insects and are widely used in timber frame construction, roofing timbers and other lower hazard end use situations.
Their key advantages are lower uptakes of water during treatment and a more natural colour compared with the green high pressure treatments. The waterbased preservative solution is applied to the timber in purpose designed industrial plants using a vacuums during the process. This provides an 'envelope' of protection and leaves the core of the timber untreated and dry. The low uptake of water as a result of the process quickly evaporates leaving the treated timber at it's original dimensions and moisture content.
