Authentic Appearance

Timber windows and doors ensure your period property retains its original charm, by replicating both the design and material of the original windows. Timber windows are often a requirement for listed building renovations.

Long-lasting and durable

Unlike other materials that may discolour and degrade over time, timber can be easily maintained with a new coat of paint or staining. Despite many people thinking that timber requires intensive maintenance, this is not the case. Maintaining your timber sash windows is easier than you think.

Energy efficient

Timber is a naturally insulating material and can provide comfortable temperatures. Many people assume that timber windows cannot be double glazed, but this is not the case. They will ensure that your property remains warm in winter and cool in summer.


Timber is a sustainable material and the eco-friendliest choice when it comes to window frames.
