Solution of Thermal Bridge under the Opening in the Cladding by Means of Support Structure for a Doors Threshold Made of Thermal Insulation Composite Material

Abstract:

In the process of sustainable construction is the emphasis placed on saving energy, reducing use of natural resources, increase the life cycle of materials by recycling, etc. Rising energy prices put increasing emphasis of builders and investors to better solution of thermal bridges. Solution can be done using a conventional materials, but also advanced materials meet the requirement of a sustainable construction and a reducing consumption of natural resources and extending of the life cycle of material. An example of such material is the thermal insulation composite material. This new developed material with low coefficient of thermal conductivity below the value of 0.100 W/mK is made of recycled waste polymer and recycled filler in the form of granules from recycled glass. In the paper are compared two variants of solution of thermal bridge under the opening in the cladding. In the first variant a wooden door opening in the perimetral cladding is deposited on a support structure for a doors threshold made of a thermal insulation composite material. In the second variant is used a lower shaped brick block. The variants of different foundation of a wooden door opening are compared in terms of a lowest surface temperature and of a temperature factor of the inner surface fRsi and its critical value fRsi,cr according to ČSN 73 0540-2 and ČSN EN ISO 10211.
