Flush Sash Windows

Flush sash windows are the latest exciting development from Liniar. They offer the realism of a traditional pre-1932 timber window combined with 21st century thermal benefits.

Many property owners require a traditional timber window frame, sometimes due to planning or environmental restrictions. Timber frames tend to be expensive, need regular maintenance and can be difficult to replace.

Liniar recognised the need to develop a casement window frame that would fit into any property where the sash fitted flush into the frame – and which could be foiled to look like traditional timber or to offer a sleek, contemporary finish. Liniar flush sash windows, like the rest of the Liniar EnergyPlus window range, are A+ rated. They offer a lower cost window with higher thermal benefits than timber – in addition to being fully secure. Available in sculptured profile with the flush finish on external faces, 28mm double or triple glazing, internally beaded, with a wide choice of opening configurations, colours, finishes, hardware and glazing.
