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 type of surround.
Casement windows feature opening elements opening to the side or outwards from the bottom. There are also the latest tilt and turn windows offering bigger window opening sizes with the facility to clean them from inside your home.
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.
