Key Features of Our Wood Windows and Doors

High performance coatings

Long lasting protection against sunlight, water and fungal attack comes from using high quality, factory-applied coatings from Sikkens, the market leader.

Internal beading

Glazed units with internal beading offer you greater security and increased longevity as the bead is on the inside, away from the weather.

Wide choice of timber

For most projects customers choose redwood heartwood. Properly dried and handled, it is a stable and long-lasting product. Hardwood options include European Oak and Sapele. All timbers are engineered to be knot-free.

Naturally long-lasting timber

Redwood heartwood contains a natural chemical resistance to wood-rotting fungi. Like all our timbers, it's a stable base for top quality coatings, guaranteeing long life and low maintenance.

Clear & efficient glazing

Our sealed glass units feature high-performance, low energy, coated glass and are Argon gas filled, allowing solar heat energy in but preventing heat from escaping from the inside.

Ventilated glazed units

The glass units stay dry thanks to a drainage channel and ventilation, producing a free flow of air around the unit.

Weather-tight dual seals

Dual weather strips give you better insulation and improved weather tightness.
