HF 100

This timber only window uses highly finger-jointed and largely knot-free heartwood, which lifts the product to a higher level. Finger-jointed timber ensures that there will be negligible warping or movement of the timber that could compromise the windows over the lifespan of the product. The pine itself comes from slow-growing Scandinavian forests. Solid oak is also available as an extra-cost option. These windows are outwards opening with the possibility of top guided, side guided or fully reversible. Double or triple glazing is available for highest energy efficiency; HF 100 with triple glazing is especially suitable for low energy buildings.
