Materials, Finishes & Options

Only engineered timber is used to manufacture our windows. This provides superior strength, stability and a knot-free finish - qualities for which our products are renowned. Standard woods are Pine (finger-joint or clear faced), Oak, Larch and Meranti. Other species of traditional (Eucalyptus, Mahogany) or exotic (Hemlock, Oregon, White Saraya) timber available upon request. All timbers are carefully selected and treated. 

Windows are fully factory finished using the highest quality ecological spray applied, water based, micro-porous finishing system. The finishing coat is elastic and moves together with the wood to let the wood breathe.

A wide variety of RAL and stain colour options are available to meet our customers’ requirements. All of our paints and lacquers are environmentally friendly, ecologically clean and harmless to the environment.
