Exterior cladding and outdoor construction


Decay- and weather resistance are important characteristics for a cladding board. WarmClad is an excellent choice for exterior cladding. Its decay resistance class is I-II and its usable life is many times greater than that of untreated wood. WarmClad’s moisture content is half that of normal wood and surface splitting caused by UV-radiation will be less than with normal wood.


VivaxColor is a quality and easy-to-use choice for exterior cladding. It features all the good characteristics provided by thermal treatment: it has excellent characteristics for decay resistance, weather resistance and thermal insulation. For the user VivaxColor is an easy and worry-free product: it is ready for immediate installation. We trust in the fine characteristics the process provides in the wood and offer a 10 year guarantee for the paint surface.
