Windows are generally made from one of the following materials:
Timber (softwood or hardwood), aluminium or plastic (PVC-U).
Softwood is the cheapest option; however it will soon deteriorate if not painted regularly and also tends to warp with changes of temperature.
Hardwood is far more durable and also offers good thermal insulation.
It also needs regular maintenance, but one coat of preservative wood stain makes this an easier task than painting. Hardwood is expensive and can cost the same as top quality PVC-U.
Aluminium is the strongest maintenance-free window material, but as on its own is a poor insulator, so most manufacturers offer some sort of thermal barrier (like thin PVC-U) to help prevent condensation forming on the frames.
PVC-U frames come in white and in wood-grain finish, but unlike wood you don't have to paint them.
Glass
[image #3 align=right]Just as important as the frames is your choice of glass as this can help reduce heat loss and improve energy efficiency. With standard double-glazing, the air in the cavity between the two layers of glazing acts as an insulator. Replacing the air with an insulating gas like Argon or Krypton will increase thermal performance.
Coat the glass facing the inside with a reflective coating and this is improved even more.
If over-heating is a concern, then specify glass with a coating on the inside so the sun's rays are reflected back.
To improve sound insulation increase the size of the cavity between the two panes of glass.
Triple glazing can also help here, as the extra weight of the window will reduce sound vibrations.
Remember: glass is not only for looking through - but looking at. Why not go for stained glass for some of the windows in your new home?
Doors
With front doors, hardwood is the most popular choice, although other material options like glazed PVC-u composite doors and steel doors benefit from being very secure and virtually maintenance-free, and can, if you choose, be made to appear like wood.
Internal doors are usually made from softwoods. To increase the sense of light in your home consider using glazed internal doors too. Save space by choosing sliding or folding doors around the home.
So which do you choose modern uPVC or traditional timber? Well, there are pros and cons to both, but ultimately it comes down to personal preference and deciding which would suit your home the best.
uPVC:
Frames are re-enforced with steel for maximum durability and strength.
High security hinges and features.
Excellent weather resistance and ease of maintenance.
Incorporated technology to improve the overall performance of the glass unit.
Significantly reducing condensation.
Can achieve a traditional look with new sash window design and wood grain effects.
Timber:
A traditional look and feel, produced from a more sustainable source.
Re-designed products are now more durable and give more performance than ever before.
New developments in paint and coatings technology can bring dramatic reductions in maintenance.
The energy needed to transform trees into windows is lower, as are disposal costs when the windows reach the end of their life.
