Wooden window properties
Wood is a natural product which affords both positive and negative attributes. Below is list of considerations to be made aware of before selecting timber window frames:
- The look. In contrast to uPVC, nothing beats the elegance and natural look of wooden window frames. The frames add character to a building, especially a period property and each window is one of a kind.
- In the UK we typically paint our windows. This has two benefits – it improves the aesthetic and it protects the wood, meaning the windows last longer. However wood has a propensity to shrink and swell as the seasons change. This movement puts stress on the paint coating, and over time the paint will crack and ultimately flake off. This can look untidy and also let water into the window frame causing decay over the long term
- Thermal Conductivity. Wood is a terrible conductor of heat, which means it’s a great insulator and will keep the heat and the cold out depending on the season. If thermal conductivity wasn’t enough, wood is also a good acoustic insulator and has proven to be better than uPVC and aluminum at blocking out sounds.
- Cost. Wooden window frames are never a cheap option. Although some softwood window frames can compete on price with the likes of uPVC, higher-end wood species and modified wood brands such as Accoya do come at a higher cost. What drives the relative high cost of wooden window frames however is the labour. Typically it takes approximately 17 man hours to make a timber window frame due to bespoke dimensions and crafting of the wood needed to achieve the required product.
