Old foam roof renovation UV protection with liquid plastic

Old foam roof renovation with liquid plastic and fleece as UV protection for an industrial roof in Brandenburg

A flat roof foamed with PUR roof spray foam offers long-term flat roof sealing and flat roof insulation in one step. This is particularly noticeable in the cost-effectiveness of the process for large industrial roofs, but also for private bungalow owners. In the industry, flat roofs have been foamed with PUR roof spray foam as flat roof sealing with simultaneous flat roof insulation since the 1970s. Since PUR roof spray foam - also called PUR in-situ foam (since it is manufactured on site) - like any other insulation material - is only partially UV-resistant, it must be protected from UV radiation and coated with suitable UV protection.

The first generation of UV coatings in the beginning were more or less high-quality polyurethane paints, which in turn had to be reworked after a few years.

Since a flat roof with PUR roof spray foam remains tight for many years even without intact UV protection, checking the UV protection was neglected or even forgotten, especially in industry due to changes in employees.

As long as the flat roof is tight it is not noticeable....

The UV protection coatings used by isodach today are high-performance liquid plastics of the latest generation.

UV resistant - plasticizer-free - open to diffusion - permanently elastic

By incorporating a technical reinforcement fleece, the UV protection is durable and robust, so that your old foam roof is safe and tight again for a very long time.

These UV protective coatings now make a flat roof foamed with PUR roof spray foam by isodach almost maintenance-free. Only dirt should be removed once a year to keep the water drains clean.

For this purpose, isodach offers its customers maintenance contracts specifically drawn up for each roof.

Isodach is a specialist company for the renovation of old foam roofs.

For this purpose, we now have the most modern liquid plastics at our disposal, which in the long term turn a dilapidated old foam roof into a safe and tight PUR in-situ foam roof. All of this without any complex demolition.

We would be happy to provide you with detailed information about the options for preserving your old foam roof and provide you with a free, non-binding fixed price offer.
