ConceptSystem 77 Reynaers
Aluminium system for windows, doors and curtain walling · Reynaers Aluminium (Belgium)
ConceptSystem 77 Reynaers is a versatile aluminium system for windows, doors and curtain walling from Belgian manufacturer Reynaers Aluminium. The system has been developed for projects where reliable thermal insulation, contemporary architecture and long-term durability are essential. With an installation depth of 77 mm and a thermal transmittance Uf of 1.8 W/m²K, it provides a comfortable indoor climate in both residential and commercial buildings.
The thermally broken profile eliminates cold bridges between the inner and outer aluminium sections, maintaining stable geometry even under significant temperature variation. With an optimally specified glass unit Ug 1.0 W/m²K and warm edge spacer, the overall window coefficient Uw reaches 1.3 W/m²K.
ConceptSystem 77 Functional is the most versatile system in the range, equally suited to inward- and outward-opening windows, patio doors, fixed glazing elements and curtain wall constructions. The wide range of supported glass thicknesses — up to 63 mm in the vent — allows the use of high-performance glazing units. The system is compatible with other Reynaers products, simplifying integration into complex architectural projects.

ConceptSystem 77 Reynaers is an aluminium system for windows, doors and curtain walling from Belgian manufacturer Reynaers Aluminium, designed for projects with high demands on thermal performance, durability and architectural flexibility. With a frame installation depth of 68 mm and a vent depth of 77 mm, a thermal transmittance Uf of 1.8 W/m²K and a window coefficient Uw of 1.3 W/m²K, the system provides a reliable solution for both contemporary residential and commercial buildings.
ConceptSystem 77 Functional is the most versatile version in the range, enabling cohesive facades where windows, doors and fixed glazing elements read as a unified whole. This integration is particularly important in apartment buildings, office complexes and public buildings, where visual consistency and energy efficiency are equally critical. The system supports both inward and outward opening, giving designers a wide choice of solutions for different architectural concepts.
The thermal performance of the profile is based on a polyamide thermal break that effectively eliminates cold bridges between the outer and inner aluminium sections. This ensures stable profile geometry even under extreme temperature fluctuations and reduces the risk of condensation on profile surfaces. Air permeability meets Class 4 (600 Pa) — the highest standard — guaranteeing minimal air leakage and reliable airtightness.
Sound insulation Rw up to 42 dB (C: -2; Ctr: -4 dB) provides effective protection against urban noise, traffic and industrial sound. This makes ConceptSystem 77 an ideal solution for residential buildings in city centres, office spaces near busy roads, and any project where acoustic comfort is a priority.
Glazing flexibility is one of the system's key strengths: glass thicknesses from 4 to 63 mm are supported in the vent, allowing the use of both standard and high-performance triple glazing units. Four glazing methods are supported: dry glazing, siliconized glazing, internal glazing and glazing bead. The 25 mm rebate height ensures a reliable connection with a wide variety of glass units.
ConceptSystem 77 aluminium windows and doors are used across a broad range of building types: private houses and apartment buildings, offices and administrative buildings, shopping centres, hotels, schools, cultural institutions and hospitals. The system's compatibility with other Reynaers products simplifies integration in complex projects and allows common components to be shared across different facade systems.
The aluminium profile is resistant to corrosion, deformation and UV radiation, delivering a service life of 40–50 years and more. A comprehensive range of finishes is available: RAL powder coating in any colour, anodising, matt and textured coatings, as well as dual-colour execution with different tones inside and outside.
Logi24 offers delivery, professional installation and warranty service for ConceptSystem 77 Reynaers across Europe. We will help you select the optimal profile version and specification for your project — from a single residential window to a large commercial facade.
