WT 2021 standards

Aluminium meets the highest standards.

Choosing aluminium joinery for a new home or a deep thermal retrofit is subject to the same stringent standards as PVC windows. The key parameter remains the Uw thermal transmittance coefficient. To meet the WT 2021 requirements and qualify for the "Czyste Powietrze" (Clean Air) programme, this value must not exceed the standard:

WT 2021 requirement
Uw ≤ 0,9 W/(m²K)

For modern buildings that aim to combine slim aluminium aesthetics with thermal comfort, we offer two variants — standard and with a concealed sash for a clean, minimalist façade:

The glass is a key part of any window — it shapes thermal insulation, sound insulation and security. We offer 11 patterned designs as well as functional glazing (absorptive, reflective, sound-reducing, toughened and laminated).

Functional glazing matched to specific needs — protection from sun, noise or break-ins.

Absorption glass
Absorption glass
Absorbs part of the solar radiation energy and protects the room from overheating. Light transmission 32–72%. Available in various colour tints.
Reflective glass
Reflective glass
Thanks to a metal oxide layer, it reflects solar radiation and gives the facade a subtle, metallic sheen. Effective protection against overheating on the south side.
Acoustic glass
Acoustic glass
Different glass thicknesses and an enlarged space between panes provide broadband noise reduction. Indispensable on busy roads, near railway tracks and airports.
Toughened safety glass
Toughened safety glass
5× more impact-resistant than ordinary glass. Shatters into blunt small pieces — minimal risk of injury. Required by standard in glazing reaching to the floor.
Laminated safety glass VSG
Laminated safety glass VSG
Two glass panes bonded by PVB film. When broken, the shards remain stuck to the film — high security level. Used in burglar-resistant windows P4–P6.
