Optimal thermal insulation
Equipped with 24 mm double glazing, AXIS90 roof windows guarantee good thermal insulation and low emissivity, which reduces heat loss in winter and limits overheating in summer.

Bottom handle
Made of moulded zinc, the handle has three positions - one is fully closed, and two further opening positions allowing ventilation on demand.

Nordic pine wood
The wooden frames are made from sustainably sourced pine wood and treated with fungicide and insecticide protection, followed by a coat of water-based varnish.

Made in Europe
AXIS90 roof windows are manufactured in Europe in a certified (ISO 9001, ISO 14001, OHSAS 18001) production facility, which uses the latest technology to ensure the best industrial, environmental and labour standards.
