Our practical, yet stylish, casement windows offer incredible levels of heat retention and sound reduction, and are available with either double or triple glazing.

Thanks to a combination of our Low Emissivity units and our high performance Engineered Timber, we can offer uValues as low as 0.74 w/m2k (when triple-glazed) in a frame that is up to 60% stronger than standard timber! When further complemented by our Aquatex Weatherseal draught-proofing system, Core Sash casements close to form a completely airtight seal.

Available in almost any style, Core Sash casement windows are a versatile and cost-effective way to double-glaze your home, both reducing your energy bills and minimising disruptive neighbourhood noises.
