K Parker Joinery Why Choose WOOD? We are in a very competitive industry and the benefits of choosing wood for residential buildings is often forgotten so I would like to go over some good–for-wood points in the light of the growing movement for energy efficiency. Apart from being an aesthetically pleasing material, wood is far easier to work with than is often understood. By knowing the facts you can make a more informed decision about whether wood is the right material for your project. Our specialty is the manufacture of quality wooden windows, doors and mouldings of all designs. Let us look at the facts. Wood has the best thermal insulation properties of any mainstream construction material. Saves money on energy bills. Wood's cellular structure contains air pockets which limits its ability to conduct heat and gives it this good insulation. Aluminium in comparison has no air pockets and is an excellent conductor of heat which is why it is often used for cooking pots so you can imagine what happens in a house. Aluminium increases energy bills. Glass is a good conductor of heat,(ever felt your steering wheel after your car has been left in the blazing sun) that is why we are now promoting LowE glass which is an energy efficient alternative. It gives you better indoor comfort. LowE glass saves money on energy bills. Wood has the best long lasting properties. An extreme example: In 2011 Archeologists found 7000 year old timbers buried in the silt below the MI6 HQ on the banks of the river Thames. Wood structures built hundreds of years ago are still standing in Russia. Wood gives long lasting savings on energy bills
