Since 2002 VARIOTEC has been able to offer certified passive-house-suitable window and door systems. In the meantime countless residential and non-residential buildings have been fitted with VARIOTEC windows and doors. As the sole manufacturer on the market our insulated window and door systems are subject to a long-term durability test.
All systems already fulfil the requirements of future energy saving regulations. Special designs such as sound protection, burglar protection, smoke protection, summertime thermal protection, and emergency exit and panic mechanisms can be integrated.
