Timber Windows VS uPVC Windows

Before we get started on why you should choose timber windows rather than uPVC windows, here’s a case study from someone who had a bad experience with uPVC in Derbyshire.

“Buy plastic they said, its maintenance free they said. What a mistake, as the foil effect begins to ripple and peel. We now need to replace the windows again, If only we had used timber, its lifetime is twice as long and easy to maintain. The door has sagged with the unsightly hinges, oh why hadn’t we used timber, with its discreet robust hinges and appealing glazing. Why have we devalued our farmhouse with plastic, never again.

Now to rectify with timber, where the environmental impact is far less damaging than plastic, which usually end their life in landfill.”

As you can see from the images below, the wood effect uPVC has started to ripple and peel.

Which has the longest service life?

One of the biggest misconceptions regarding uPVC windows is that they last longer than timber windows. This is often not the case. As a matter of fact, Heriot-Watt University conducted a report that compares the service life, ownership cost and environmental impact of windows using timber, modified timber, aluminium-clad timber and PVC-U frames.

The analysis showed timber options considered has a longer service life than uPVC alternatives. You can read more here and here.

Depending on the severity of exposure, factory manufactured timber windows are not likely to need recoating for at least eight years. Research suggests timber, modified timber, and aluminium clad timber windows costs are less even when taking maintenance into consideration than PVCu alternatives.

Which has better efficiency?

Wood is naturally a very good insulator, regardless of the glaze of glass inside it, which makes it an excellent choice for homeowners looking to save money with new replacement windows. Aluminium windows, because they’re metal, are not recommended if you wish to have the best energy efficiency possible.

Which is better for the environment?

Correctly farmed timber is endorsed by WWF and Greenpeace. It is proven that timber is a more environmentally friendly choice of material, as uPVC emits carbon dioxide into the atmosphere and leaves 200,000 tonnes of waste a year. Timber is a fully recyclable material and is better for our atmosphere. uPVC, on the other hand, contains six of the 15 most hazardous chemicals listed by European standards. This makes Timber a much better choice for the environment.

Which is more expensive?

uPVC windows are the cheaper option when it comes to the initial purchase. However, in the long term, you will end up spending more on uPVC than you would timber windows. When timber is correctly cared and maintained for, the long term value by far outweighs uPVC.

Timber windows also repay your initial investment by boosting the value of your property, as well as lasting up to five times longer.
