Windows PROGRESS in the residential complex DIORIT

An important chapter of the project became the window systems. Emphasis was placed on the technical quality of the window system, including thermal insulation properties, but also on design. A specific requirement of the assignment turned out to be external blinds, which were offered to all apartment owners as part of the premium accessories. A limiting issue in this case was the planimetric curved shape of the building. Classic recessed boxes could not be used, both due to the impossibility of placing them on the planimetric curved lintel and due to concerns about thermal bridges. Ultimately, the demanding conditions were fulfilled by the PROGRESS window systems with ALU EF+ aluminum cladding, which offer users of the apartment units the possibility of a systematic external shading solution without the need for recessed boxes for exterior blinds. Simply put, everything is part of the window supply, which extremely simplified the installation and increased the comfort of the solution from an aesthetic perspective as well. The PROGRESS window systems are made from the composite material RAU-FIPRO X, which provides the windows with above-standard static and thermal insulation properties, including sound insulation. For most window assemblies, it was unnecessary to use steel reinforcement, as the composite material together with the profile construction ensures the necessary shape stability. Instead, thermal insulation modules were inserted into the profile cavities to improve the thermal insulation of the assembly (most windows have Uw = 0.62 W/m²K). In the gable walls, HS portals (from sizes 3300 x 2400 to 4600 x 2400 mm) made from composite material were also used in the window assemblies (9 to 10 m). Interestingly, here Uw = 0.88 W/m²K is achieved. In the inner courtyard, the windows were installed in a fully projected system installation DAFE PUREX BASIC to eliminate thermal bridges. For windows with sills on the street facade and gables, a semi-projected installation was used for the same reason (recessing the window by 30 mm at the opening before the outer face of the masonry), which also had to deal with the curved shape of the building. The supply also included a set of aluminum windows Schüco AWS 70.HI (opening elements) and Schüco ADS FR 30 (fixed fire-resistant elements).

In the context of the architectural solution, attention was also paid to the design of the windows. While the windows inside are white, most of the windows on the exterior use the color shade Oxide 5. The windows in the gables in the assemblies with HS portals have the shade Blau 2600. Window assemblies with access from the garden are equipped with insulating triple glazing with Ug=0.5 with security film, while the other windows have standard insulating triple glazing with the same thermal insulation properties.

The DIORIT project deserves attention for its technical solutions as well as for its original architecture. The cascading shape, plenty of greenery, low energy consumption, quality of materials, optimal use of space, and premium services are the most important attributes. The project was designed by the architectural office DRNH (architect Antonín Novák), the developer is Diorit, a.s., and the general contractor is Moravostav a.s. The supplier of the window systems is DAFE - PLAST Jihlava, s.r.o.
