    Sliding Sash Windows Frequently Asked Questions

    Your sliding sash window questions answered.

    A sliding sash window consists of two panels (sashes) that slide vertically past each other within the frame. The design originates from Georgian and Victorian architecture and remains a popular choice for period properties across Berkshire and beyond.
    Yes — sliding sash windows are one of the most sympathetic replacements for period properties. If your property is listed or in a conservation area in Berkshire, we recommend checking with your local planning authority before ordering, or visiting the Planning Portal for guidance.
    Modern sliding sash windows are far more energy efficient than their traditional counterparts. Our sash windows are A-rated and feature advanced weather sealing and double glazing to minimise heat loss — keeping your home warm and your energy bills low.

    What Our Customers Think About Us

    Was lucky enough to use oakwood installations on my warm roof conservatory along with 3 windows and aluminium bi fold doors. I couldn't have chosen a more professional and polite company. the quotation and survey was done accurately and in a timely manner and the installations were all meticulously installed. I can thoroughly recommend without hesitation. many thanks for a job well done

    Very Impressed! We had all our windows replaced in our bungalow, new bi-folding doors fitted, turned a bedroom window into beautiful French doors going onto the patio, new front door, and turned the old back door into a lovely window! They also removed the old French doors that were not so greatly placed going through the middle of the living room! It now looks amazing! And they saved my mum some bruises as she can now walk through the living room without walking into the glass doors, forgetting they were there

    Had our patio doors swapped out for bi-folds and a kitchen window changed at the same time - I would highly recommend Oakwood. Work was done quickly and to a very high standard - will defo use them again - thank you
