Do you know that the total amount of energy used to make a timber window is approximately one fifth (1/5) of the energy used to make a Plastic (PVC) window.

There are many timber windows used today, which are more than 100 years old. They are mainly replaced because a better glazing unit is required. All windows made from timber are, unlike other construction materials, 100% recyclable. All timber used in our products originate from sustainable well-managed Scandinavian forests.

The design approach

One can argue that in today’s house the need to design for timber longevity in windows, doors and other external timbers is redundant because of the availability of preservative- treated products. Perhaps, but this proliferation of treated timber comes at a recognised environmental cost.

As wind and water will always attack our houses we can learn something from another product routinely exposed to the weather- the car. Modern principles of car design maintain that 'If you cannot stop water coming in, make sure it has a way of getting out again.' Cars on the roads these days rust a lot less than they did 20 years ago, not merely by additional rust-proofing, but by applying this basic design principle.

Fully factory finished timber windows and doors also incorporate this design principle and are therefore probably among the products which can realistically be supplied untreated with minimal impact on product life expectancy.
