Environmental impact of wooden windows and doors

Wooden windows and doors are a good choice for the environment, they are biodegradable and absorb CO2 from the atmosphere.

In recent studies researchers have found that when properly protected with paint or woodstain, timber windows last twice as long as PVCu. Reducing the number of windows that become landfill is good for the planet and they sport top-end, performance double glazing; ensuring that any loss of energy is further minimised - keeping heat inside the home where it is most beneficial.

Less waste

Multi-layered timber is produced by joining wood sections together to create one piece of timber which is strong and very durable. This use of wood sections means that just the knots can be cut out whilst the remainder of the wood is used. The knot free multi-layered timber that is left is a fantastically strong material, more of the wood is used and waste is reduced even further. 

Protective measures

The longevity of the door, or window, requires a thorough application of paint or woodstain to protect the wood from contact from any moisture. Our environmentally friendly water-based paints and stains contain no solvents and are spray applied before assembly. This delivers the most thorough protection for a low maintenance lifetime. 


Our timber windows are a great choice for people who want to help lessen their impact on the planet, we only use sustainable European Redwood timber as standard in all our windows and doors.

The use of European Redwood fulfills several requirements, it is easily grown and grows with few knots,  the wood itself is naturally water resistant and the tree grows beautifully straight - making it easy to process with little waste.  It provides a steady supply of wood for all uses - it has been used for construction purposes for many years.  

Dale Windows endorses FSC, the Forestry Stewardship Council,  a not-for-profit non-government organization created to  promote responsible management of the worlds forests.  They actively seek to make all wood fully traceable and change is happening. Their promotion explains why there is a need for full chain of custody - to safeguard the forests of our planet, with wood only sold from sustainable forests, rare species might be saved and deforestation slowed.
