We offer roof insulation tests before installation of photovoltaic panels

News, 17. 08. 2023

If you are considering to install photovoltaic panels on your flat roof, you should pay attention to the thermal insulation characteristics. If it is not sufficiently rigid, it could be deformed and consequently the waterproofing could be compromised, resulting in water leakage into the roof construction. Therefore, UCEEB offers homeowners and designers laboratory measurements of the strength of thermal insulators to provide an ideal basis for the correct design of the anchorage.

For anchoring solar panels on flat roofs, triangular metal frames are usually used, which are first mounted on the roof and then weighted against the effects of the wind. Flat roofs usually have expanded polystyrene (EPS) thermal insulation, which may not be sufficiently rigid. The metal structure can then, over time, become embedded in the thermal insulation and breach both the asphalt and foil waterproofing. This can easily lead to water leakage into the roof construction.

We can measure the response of the thermal insulation - the strength according to EN 826 - from the taken samples. This provides the designer with an ideal basis for the correct design of the anchorage. For a specific offer you can contact Ing. Tomáš Vlach, Ph.D. at tomas.vlach@cvut.cz.
