From a traditional country cottage to a modern house or new extension, Alitherm casement windows from Smart Systems offer high security, weather protection and a beautiful appearance inside and out.
Ultra-slim frames allow more natural light into your home and come in a choice of traditional or modern profile designs. An extensive range of personalisation options lets you create your perfect new window. Best of all they integrate with our entire range of residential doors, sliding or bifolding doors too.
Every window comes expertly crafted, made-to-measure and with a beautiful colour on the inside and outside surfaces, matched to high quality insulated glass units.
Technology & Design
Cutting-edge design and quality craftsmanship makes these windows suitable for replacing old windows or for a newly built opening. Thermally insulated frames come in several different types and sizes. As a result, these windows fit directly to the new opening or quickly and neatly replace old windows. They also come with frame options to fit timber, stone or other types of surround.
Casement windows feature opening elements opening to the side or outwards from the bottom.
The design of our Alitherm casement windows range ensures you get the perfect combination of opening elements, proportions and overall window design. Thermally enhanced profiles work with the high specification glass units, maximising the light into your home and providing excellent ventilation when open and energy efficiency when close.
Durable powder coated finishes are low maintenance, easy to keep clean and protect the aluminium surface from the elements.
