Thermally Efficient Double or Triple Glazing

A++ energy rated flush sash windows in Slough

Although timber is a natural insulator, uPVC flush sash windows don’t suffer from the same issues like warping, rotting, splitting, and letting cold draughts inside.

What’s different about Liniar flush sash windows? Well, they’re far more efficient than traditional uPVC window profiles, trapping much more heat inside than most. With a choice of the standard 4-chamber profile or the supreme Liniar EnergyPlus 6-chamber profile, coupled with advanced double or triple glazing, Liniar flush sash windows in Slough are designed to cut energy bills and household carbon emissions across the board whilst keeping your home warm and cosy all year round.
