Your roof tiles are able to breathe, will be permeable to water vapour and will let air and moisture pass through from one side to the other. A breathing roof will improve the insulation properties. Just a 5% content of damp in building materials can lower the thermal resistance by up to 50%.

Self cleaning efficiency

Dirt particles are unable to obtain a hold on roof tiles treated with the Invisible Insulation System from Spectrum Energy, and will simply flow off with rainfall. Your roof remains clean and attractive. Even on sides which are particularly exposed to the weather like on the north-facing side or roofs in shade, as well as in areas with high humidity or salt spray from the sea.

Proven Performance

As a leading German manufacturer of the Invisible Insulation System, we have combined all our expertise with the latest technology to create a product which gives building surfaces self cleaning properties and extremely super hydrophobic capabilities.

Thermal efficiency

Moisture in building materials is the leading contributor to energy loss. Wet materials transfer heat much quicker than dry materials. In the same way that a quality, breathable, thermal jacket will keep your body warm and dry, treating your building with Spectrum Energy System Water Repellent will have exactly the same effect.

Water Repellent

You will recognise the excellent water repellent properties by their beading behaviour. It will make your roof tiles dry and extremely resistant to biological hazards, mould, mildew, and others. A dry roof using our Invisible Insulation System will improve the thermal resistance, prevent frost damage and reduce the growth of microorganisms.
