Why SlimSASH?
These 70mm PVCu windows feature a unique six-chamber SlimSASH profile, designed exclusively for Whiteline and its customers.
With less profile material used, SlimSASH windows have a sleek, elegant appearance while offering a larger glass area that allows more natural daylight into the home. Despite their slim design, they maintain exceptional energy efficiency and security. The chamfered external profile includes a distinctive putty line feature, with a choice of chamfered or sculptured internal beading for a refined finish. Available in a wide range of colours and finishes, they can be tailored to complement any home’s style. These windows are internally glazed for enhanced security, with a slimline frame that maximizes the glass area. Made from high-impact modified PVCu, they resist cracking due to age or extreme cold. The fully welded frame ensures durability, while push-button, key-lockable handles, available in multiple colours, include a lockable night vent position for added functionality.
