Separate from CS 77 windows
The Functional door leaf is 68 mm deep; the window version has different geometry. A shared series name does not make their specifications interchangeable.
REYNAERS ALUMINIUM / Aluminium doors
ConceptSystem 77
A thermally broken Reynaers door system with a 68 mm frame. The Functional variant provides a glazed entrance with dedicated door geometry, requiring checks for daily operating loads and perimeter sealing.
SPECIFICATIONS
ConceptSystem 77 / Functional
| Frame depth | 68 mm |
|---|---|
| Door leaf depth | 68 mm |
| Min. frame–leaf sightline, inward opening | 144 mm |
| Leaf width, catalogue range | 500–1400 mm |
| Max. leaf height | 3000 mm |
| Uf — best catalogue value | 1.8 W/m²K |
| Ud — reference door below | 1.4 W/m²K |
| Air tightness | 4 (600 Pa) |
| Water tightness | 7A (300 Pa) |
| Wind load resistance | C2 (800 Pa) |
| Acoustics Rw(C;Ctr) | 41(−1;−4) dB |
What these values apply to
Ud = 1.4 W/m²K refers to a single inward-opening door: 1.23 × 2.18 m, Ug = 1.0 W/m²K, warm-edge spacer, 150 mm sightline and 36 mm glazing. This is not the minimum 144 mm sightline combination. Ud describes the complete door and Uf the profile; window Uw is not substituted here.
Performance depends on dimensions, profile combinations, hardware and glazing. Each opening requires its own specification; catalogue maxima are not a guarantee for every element.
The table follows the manufacturer’s exact door variant. The global technical sheet supplies Ud and its reference conditions; the Ukrainian sheet is also linked.

Variant availability, hardware and delivery terms in Ukraine must be confirmed for the project. A catalogue listing does not imply stock availability.
DESIGN CHECKS
From a profile to a working element.
Daily use
Before ordering, agree the opening direction, clear passage, hinges, lock and closer. Check the complete leaf weight against the chosen glazing and hardware; no unverified weight limit is stated.
Special variants
Fire-resistant, bullet-resistant and panel doors require their own profiles, infill and documentation. Functional specifications do not establish those properties.
