THERMOBLOK® Persiana BASIC 90 is a thermally insulating monoblock designed to accommodate windows and doors with external-frame shutters, engineered to ensure high thermal insulation performance, continuity of the building envelope and quick, precise installation of the entire window system. Fully made to measure, it can be configured for window installation either flush with the internal wall or centre-aligned, adapting to specific design requirements. The window frame is recessed on three sides and, where the wall construction allows, the system can also be configured to accommodate a recessed fly screen on three sides. The front rebates are available in 72 mm or 54 mm configurations, whilst the fourth side, an 80 mm deep channel, is fitted with a dedicated thermal break.
TECHNICAL SPECIFICATIONS:
The system is made from EPS Neopor (sintered expanded polystyrene with graphite additive) with a density of 30 kg/m³ and a declared thermal conductivity of λD = 0.030 W/mK. The top rail and side rails incorporate a load-bearing structure made of 18 mm phenolic-faced plywood, designed to act simultaneously as a sub-frame for both the internal window unit and the external shutter.
This construction solution allows the fixing of both the window unit and the external shutter to be integrated into a single structural element, improving installation precision, the stability of the entire system and the continuity of the window opening’s insulation.
The TBK Type BASIC 90 thermally insulated side jambs, with a thickness of 90 mm and a depth that varies according to the project, ensure high thermal insulation performance and help reduce thermal bridges, whilst guaranteeing the correct seating of both the window unit and the framed shutter.
The TBK Type 80 thermal insulation side panel, made from high-density XPS, completes the window assembly by eliminating the lower thermal bridge. The special recessed design facilitates assembly with the side jambs and is designed to accommodate the window sill. The system is supplied with a dedicated thermal break made of XPS for windows and Purenit for French windows.
The system can be supplemented with numerous optional extras, including provision for a recessed fly screen via a special aluminium profile and the TBK skim-coat system, comprising external wall insulation mortar, a plaster-reinforcing mesh and technical PVC profiles to ensure professional installation and a finish that blends seamlessly with the façade.
THERMAL PERFORMANCE
Linear thermal transmittance of the jamb (Ψ): 0.000 W/(mK) without external insulation and 0.019 W/(mK) with external insulation, in accordance with UNI EN ISO 10211.
Linear thermal transmittance of the fourth side (Ψ): 0.044 W/(mK) without external insulation and 0.17 W/(mK) with external insulation, in accordance with UNI EN ISO 10211.
