Heat / humidity

Product development / proof

We support our customers in product development and with tests for thermal insulation and moisture protection as part of proof of performance:

• We detect thermal bridges for window and door constructions and participate in the development of solutions.
• For sub-roof systems, we offer tests of rainproofness, increased rainproofness, nail tightness, and walkability. Our test procedure focuses on the entire sub-roof system with all connections and provides quality assurance for sub-roofs.
• We check the airtightness of component connections, building materials (e.g. OSB) or component structures in the laboratory.

Quality assurance / proof

We contribute to quality assurance in construction with tests during the shell construction and after the completion of buildings:

• We measure airtightness using the differential pressure measuring method (= Blower-Door-Test). For passive houses and buildings with ventilation systems, we certify the prescribed limit values for the air exchange rate n50 and carry out leak detection. In addition to thermal insulation, an airtight construction in timber construction also provides safety in terms of moisture protection because the penetration of indoor air into the component structure is reduced.
• We use thermal imaging to test the thermal insulation of buildings. Using a thermal imaging camera, we show thermal bridges and other problem areas.

Moisture protection – proof

We create the design of component structures with regard to moisture protection using the Glaser method or hygrothermal simulation. Depending on the complexity and the issue at hand, we select the appropriate procedure, prove the moisture protection, and help to find the solution. Our area of expertise is moisture protection and the forecast of the moisture behaviour of component structures using moisture-sensitive materials under real conditions (site climate, on-site shading and horizon). We also offer this for component joints using 2-dimensional hygrothermal simulations.

Thermal insulation – proof

Wooden buildings offer good thermal insulation because, in addition to the insulation materials, wood also has a low thermal conductivity. Nevertheless, some details need an accurate test: We calculate thermal bridges in structures, windows, and doors and support manufacturers and planners in developing solutions.
