What UK Buyers Should Look for in Quality Wood Sash Windows

ISO stands for International Organization of Standardization. ISO14001 provides a systematic and responsible approach for managing the impacts of activities such as logging. PEFC "promotes sustainable forest management - environmentally, socially beneficial and economically viable management of forests for present and future generations through independent third party forest certification."

Why Choose Wood Windows?

Many customers with traditional or historic homes who want to reduce heating and cooling costs often opt for replacing their windows. Some replacement windows are made from plastic or are clad with metal or plastic. Although such windows might be energy efficient, aesthetically they're unappealing and out of place if used on a period house. Since wood has better insulating properties than either the metal or plastic used in lesser quality windows, opting for timber sash windows not only preserves the character of the house but also provides superior insulating and soundproofing properties.

What to Look for in Quality Replacement Sash Windows

To be authentic, wood replacement windows should be made with joinery grade wood frames and hardwood sills. European redwood is often used because of its uniform appearance and fine, straight grain. In some cases, pressure treated wood may be used for extra durability and resistance to rot and insect damage. This wood is usually treated with a preservative, insecticide, fungicide and a waterproofing agent such as a wax-based resin. Many wooden windows come pre-primed, a feature that saves a lot of time, labor and money. Optionally, the customer can choose to have the windows painted at the factory in either a satin or gloss finish in a color that will compliment the exterior of their home.

Repair Issues

Wooden sash windows have the benefit of being repairable. They can be taken apart to repair or replace worn or broken sash cords that facilitate opening and closing the window. With proper maintenance, these windows can last for decades. Most plastic-based (PVC) windows generally carry only a 10-year warranty and cannot be dismantled in order to repair them. In addition, PVC windows cannot be built to duplicate the intricate moldings and architectural details found on historic or period homes. While wood sash replacement windows might be prone to sticking, rot associated with excess moisture, rattling associated with loose glass panes and drafts, all of these problems can be forestalled with good maintenance. In additional all are repairable conditions.

The many benefits wood sash windows are virtually self-evident. With proper maintenance and repair, UK homeowners can expect years, and in some cases, centuries of trouble-free use.
