rational and money saving

ETRUM windows and balcony doors are a versatile family from WnD. Prices are not high, so you can save money while enjoying good quality. Many additional options of connectors and extension profiles allow to build even large, multi-element structures. The classic profiles will fit perfectly into traditional and modern construction.

There are also monobloc and renovation frames available, which make installation easier by covering the insulation layer from the outside or window opening imperfections from the inside.


The rational design of the ETRUM system ensures good insulation parameters and durability for years at a good price. ETRUM is the most popular product in WnD’s offer, and at the same time its quality is confirmed by a 5-year guarantee on windows and a 2-year guarantee on fittings.


The ETRUM windows and balcony doors are available in many veneers imitating wood, steel structure and also in trendy RAL colours. This makes it easy to match windows to façades or interiors.


Reinforcements up to 2 mm thick and a suitable cross-section of the profile ensure a robust and durable structure. The gasket system helps keep the fittings in good condition for years. This way, ETRUM balcony windows and doors are stable and remain functional regardless of the prevailing weather conditions.


The possibility of wider glazing, a 5-chamber profile structure and a gasket system ensure optimum thermal insulation. With this, the ETRUM system helps to reduce the costs of space heating.
