Wondering how to choose sash windows without compromising on security, thermal efficiency or durability? Read on…
Can I replace my sash windows and still meet conservation requirements?
By manufacturing our sash window frames from engineered timber, we are able to enhance the performance of our products’ durability, maintenance and energy efficiency. We are able to maintain original designs while incorporating modern energy and security features so that our windows meet demands and conservation document Q regulations.
Are sash window locks safe and secure?
Our windows can be designed with secure locking systems, child safety restrictors and optional Georgian bars, meeting demands for style and security, and ensuring you, your family and home are safe.
Should I choose UPVC or timber frames for my sash windows?
If properly maintained, traditional wooden sash windows can last for over one hundred years. Although UPVC frames are usually cheaper, they tend not to last as long as wooden frames. Timbertherm’s windows are manufactured from engineered timber which means the lifespan of your windows increase and the cost reduces.
Are sash windows draughty?
Traditional sash windows are often associated with draughts and cold spots, since many units are old and single-glazed. Our sash windows incorporate modern technologies, such as engineered timber sections, double or triple glazing options and draught-proofing to ensure your home stays energy efficient and comfortable.
How much do sash windows cost?
As with all of our products, the cost of your sash windows will depend on the size, choice of materials and any additional features. Taking these factors into consideration, our team can survey your property and supply you with a free, no obligation quote that will stay valid for six months.
Will my sash windows reliably open and close for years to come?
Timbertherm’s sash window designs use a concealed, spring-loaded contemporary balance mechanism. This system is more durable than the traditional balance tubes or weighted cords and pulleys fitted in the side jamb of older sash windows.
