Our windows have been designed to offer homeowners a range of distinct advantages, delivering stunning good looks, high performance, strength and durability.
Because windows and doors are a key feature of a home, aesthetics are important. Slim elegant sightlines are features of the Alitherm window system which can be enhanced by an ovolo or chamfered edge appearance. Dual colour is also an option giving the homeowner maximum flexibility by offering a choice of colours and finishes externally and internally.
All Alitherm 300 profiles utilise Smart’s innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Value of a product.
