Sliding Sash Styles
Sliding Sash Spiral Balance
Spiral Balance is our most popular style of sash window with maintenance-free, semi-concealed, in-frame spiral balances. The balances are available in either White, Brown, Black or Cream to match your chosen finish. The balances too can be completely concealed so they do not detract from the window’s traditional style.
Sliding Sash Cords & Weights
Often called box sash or sash and case windows, our cords & weights sash windows are the essence of traditional design; featuring lead or steel weights, nylon sash cords with exceptional tensile strength and draught-proof axel pulley wheels. They are available with an easy clean facility and feature internal access to both the internal and external sash weight pockets is for ease of future maintenance.

Glazing is an important design element for any project and can make all the difference when creating a feature window or door. A variety of obscure glazing patterns are available with different designs offering varying privacy levels (rated 1-5 with 5 being the highest level).
Redwood or hardwood timber
All our products are manufactured using FSC100% engineered laminated timber. We offer both redwood (Scots Pine) and hardwood (Dark Red Meranti) – both with the same extensive warranty. When comparing the two, our hardwood has a more of an open grain structure meaning it gives more of a textured finish, particularly when stained.

Sliding Sash Windows FAQ's
How do sash windows operate?
Do you offer traditional sliding sash windows?
Whats the difference between spiral balance and cords and weights?
Do you offer a tilt facility on your sash windows?
At Bereco we don’t offer a tilt facility; this style of window usually comes with unsightly and non-compressing brush seals that can affect weather performance. However, our cords & weights option is available with an easy clean system that allows the bottom sash to open inwards side hung.
