To create the perfect quiescent microclimate Western Red Cedar is the material from which every cold frame is constructed, containing natural oils that resist moisture decay and infestation, looking after itself without a second thought from you, remaining sound solid and beautiful for decades.


Red Cedar is endowed with qualities that further reinforce its superiority for coldframe construction, it neither warps nor twists.
