The Eco Idealu takes aluminium clad timber windows to the next level by combining an additional layer of insulating foam with the beauty of timber and toughness of aluminium. It achieves excellent thermal performance and gives your home a luxurious look both inside and out. Together with triple glazing and warm edge spacers, the Eco Idealu can achieve passive house certified Uw-values as low as 0.78 W/m²K thanks to its special polyurethane insulating wedge which ensures the aluminium does not contact the timber. This ensures vapour diffusion and excellent energy values. The Eco Idealu’s sleek look makes it ideal for modern architectural projects and perfect for passive house builds. Customise it further with special glazing options and the choice of different colours and finishes for each side.
