70mm Flush Sash Window
The design of flush sash windows takes inspiration from traditional timber joinery, allowing the sash to sit flush in the frame. They are ideal for homeowners looking to bring a traditional charm to their home.
70mm Flush Sash
Designed from scratch
The original, 70mm range of flush sash casement windows highlights another industry-first for TSL in Ireland. Recognising the need for a more traditional style of window, we created this 70mm flush sash window system from scratch.
Stylish
Sleek and flush, with no tell-tale uPVC overlap, Liniar 70mm flush sash windows offer all the benefits of uPVC’s thermal efficiency, combined with the beautiful appearance of timber.
Thermally efficient
Many property owners require the look of a traditional timber window frame, sometimes due to planning or environmental restrictions. Our flush sash windows include Liniar’s patented bubble gasket for the ultimate in weather performance, and can even be mechanically jointed for a truly authentic timber appearance.
