TBK THERMOBLOK® – BASIC Sun Shading Thermally insulated shutter box for sun shading systems

THERMOBLOK® – BASIC Sun Shading is a thermally insulating monoblock designed for the installation of chain-operated and/or cord-operated sunshades.‎ The system guarantees high thermal insulation performance, continuity of the building envelope and seamless integration of the shading system into the window opening.‎ Fully made to measure, it can be configured for window installation either flush with the internal wall or centred within the wall.‎ The compartment for the sunshade is sized according to the technical specifications of the shading system and lined internally with BetonWood panels, which improve sound insulation and ensure a hard-wearing, durable finish.‎ 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.‎ TECHNICAL SPECIFICATIONS: The box is made from EPS Neopor (sintered expanded polystyrene with added graphite) with a density of 30 kg/m³ and a declared thermal conductivity of λD = 0.‎030 W/mK.‎ The structure is reinforced with multilayer timber inserts, ensuring strength and ease of fixing.‎ The compartment housing the sunshade is lined internally with BetonWood panels, a material that helps improve sound insulation, increases the system’s strength and ensures a durable finish to the internal surfaces of the box.‎ The system is designed to accommodate windows and doors either flush with the internal wall or centred, adapting to different design requirements.‎ The TBK Type 90 FR thermal insulation side panels, also made from Neopor EPS with a structural core of plywood, are fitted with a press-formed sheet metal guide rail, designed to allow the installation of the main types of cord-operated and chain-operated sunshades available on the market.‎ The system is completed by specialised PVC corner profiles, which ensure correct alignment with the external wall face and facilitate finishing work.‎ The TBK Type 80 thermal insulation panel for the fourth side, made from high-density XPS, completes the window assembly by eliminating the lower thermal bridge.‎ It is designed to accommodate the window sill and is supplied with a dedicated thermal break in XPS for windows and in Purenit for French windows.‎ The system can be supplemented with numerous optional extras, including provision for a recessed fly screen via a specialised aluminium profile and the TBK skim-coating 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 Thermal transmittance of the roller shutter box (Usb): 0.‎25 W/(m²K) in accordance with UNI EN ISO 10077-2.‎ Linear thermal transmittance of the side panel (Ψ): 0.‎000 W/(mK) without external insulation and 0.‎043 W/(mK) with external insulation, in accordance with UNI EN ISO 10211.‎ Linear thermal transmittance of the fourth side (Ψ): 0.‎049 W/(mK) without external insulation and 0.‎18 W/(mK) with external insulation, in accordance with UNI EN ISO 10211.‎ THERMOBLOK® is the professional range of prefabricated thermal insulation monoblocks for window openings, designed and patented by TBK to offer a comprehensive, efficient and bespoke solution for window and door installation.‎ Drawing on experience gained in the window opening sector, the THERMOBLOK® range allows all the functional elements of the window opening – roller shutter box, side jambs, fourth side and accessories – to be integrated into a single system, ensuring continuous insulation and effectively reducing thermal bridges.‎ THERMOBLOK® is designed and manufactured to measure, according to the building’s characteristics, the wall’s construction and the specific requirements of the building site.‎ This bespoke design ensures high performance, simplified installation and seamless integration with the building system.‎ The range includes various configurations to meet a wide variety of design requirements, whilst maintaining the same high quality standards in terms of thermal insulation, durability, construction precision and ease of installation.‎ Why choose THERMOBLOK® A system designed and patented by TBK.‎ Fully bespoke monoblocks.‎ Reduction of thermal bridges around the window opening.‎ Integration of the roller shutter box, side panels, fourth side and accessories into a single system.‎ Suitable for both new builds and energy-efficiency refurbishment projects.‎ Solutions that can be customised to meet the architectural and performance requirements of the project.‎ High-quality construction and ease of installation.‎ THERMOBLOK® is TBK’s solution for creating a high-performance window opening, combining energy efficiency, build quality and maximum design freedom.‎ Further info from manufacturer on THERMOBLOK® – BASIC Sun Shading TBK
