Flush Sash Windows
If you own a character cottage or your home is either a listed building, or in a conservation area, then flush sash windows make an excellent choice for your window frames. Advances in modern technology mean that these models now look and perform better than ever whilst looking indistinguishable from traditional timber frames, yet with all the benefits of uPVC.
The type of window you choose will depend on the unique style of your property. Traditional properties can be enhanced with bar details including Victorian or cottage styles. If you live in a conservation area you may need to replace windows with models that reflect the original design.

Benefits of Flush Sash Windows
Flush sash windows add and retain character whilst looking almost identical to timber windows. Many architects recommend traditional timber windows because of their feel-good factor, constructed from wood and their suitability to period properties.
However, unlike traditional timber windows, flush sash windows are a much stronger, sturdier option and provide many benefits including insulating your home, enhanced safety features, low maintenance and much better durability.
They can have a natural woodgrain finish, a smooth painted finish or a painted woodgrain finish to match your home.
