The monoblock frame is a profile designed for fitting the window within the insulation layer. Its wider construction lets the window match the thickness of the insulation and cover it neatly, with no extra finishing work.

Energy-efficient windows compliant with WT 2021
WT 2021 requirement: the same high insulation standards also apply to windows being replaced in existing buildings if the owner intends to take advantage of funding programmes such as “Czyste Powietrze” (Clean Air).
For those seeking proven solutions that fit perfectly within the standards of WT 2021 and the programme “Czyste Powietrze” (Clean Air), we have created the BUDVAR T-Comfort Mono window range in an energy-efficient specification, ready for fitting within the insulation layer in new builds and thermal upgrades.

Corner cross-section of the T‑Comfort Mono profile: seven thermal chambers, steel core, EPDM gasket and double or triple glazing. The soft lines of the T‑Classic Mono frame and the modern T‑Comfort sash (Z051) in one window.

- Thermal chambers
- 7 chambers
Seven chambers in the frame form an air barrier that limits heat loss and outside noise.
- Profile core
- Steel reinforcement
Steel in the frame and sash stiffens the structure and gives the hardware a solid fixing.
- Gaskets
- EPDM · 2-3
Durable EPDM gaskets keep the home airtight and quiet.
- Glazing unit
- 36 mm · triple
Low-E glass and a warm-edge spacer give a low Ug value.
Engineering that works quietly.
Triple glazing with a warm-edge spacer and Ug 0.7 W/m²K. Fitted within the insulation layer, the window reduces the thermal bridge at the wall junction.
* Uw value per EN ISO 10077-2 for a simple reference window measuring 1230 × 1480 mm with the option of standard triple glazing with a warm edge.
Monoblock frame in depths from 105 to 165 mm, matched to the insulation thickness. Seven chambers keep heat in and noise out, while steel reinforcement stiffens the frame and sash.
Four frame depths for insulation from 100 to 160 mm.
