Marbet - Warm Mounting Beam
From 2021 onwards, the thermal insulation requirements for partitions in residential buildings will significantly increase. Marbet Warm Mounting Beam is the best way to ensure airtight window installation corresponding to the highest demands of investors. An appropriate quality of window installation allows heat loss to be reduced and significant savings in the building’s maintenance costs to be gained.
The aim of energy-efficient building is to minimise heat loss resulting from thermal bridges and permeability of connections.
Installing wood joinery (windows, doors) with excellent insulation parameters is not enough. Therefore, when installing the joinery, it is recommended to ensure that both windows and balcony doors slightly protrude from the face of the wall (are moved to the building’s outer insulation layer) and that connections of window and door frames with the wall are as airtight as possible.
The inventiveness of the window joinery solution based on segment items from hard polystyrene EPS – the Marbet Warm Mounting Beam (CBM) - relies on extending the jamb by implementing a tight support frame made from these elements, similarly to “building with bricks”. The beams together with the supporting mounting elements, including an under-window beam (BP), inner (PPW) and outer (PSS) bases of the window sills, and other connecting elements available on the construction market, such as adhesives and PU foams, mounting couplings and sealing strips, ensure both airtight and simple installation of windows and doors available on the market.
The system was designed with the participation of experts and practitioners - window assemblers and manufacturers. Installation of the joinery on the basis of elements from the CBM system complies with the ITB guidelines and was approved by the National Technical Assessment.
