To improve a building's energy performance, the roof can be better insulated or solar panels installed. In fact, the two are complementary.
Installing photovoltaic panels in your home or business is always a worthwhile investment. But it can be even more effective if combined with roof insulation. A poorly insulated roof represents an energy loss of around 30%. It would be a shame to lose all the benefits of your solar system.
No photovoltaic panels without a good roof
Another argument is that solar panels now have a lifespan of 25 to 30 years. So it's best to be sure of the quality of the roof covering and its general condition. To avoid additional costs and work in the future.
Insulation is sometimes mandatory
Good roof insulation is recommended in Wallonia and Brussels, but mandatory in Flanders. To make a building sustainable and achieve maximum performance, a thickness of 9 to 12 cm is required. Whether you choose petrochemical insulation (PIR/PUR) or natural insulation. Whether you're insulating your home or your business.
Don't overlook waterproofing
Solar panels also need to be watertight. Whether you have a pitched or flat roof. For flat roofs, Soltis is approved to install Resitrix® EPDM (ethylene-propylene-diene monomer) membranes - 3x more resistant than other membranes - and Derbigum bitumen membranes. What's more, we offer you a 10-year guarantee on the waterproofing of your roof following installation of the photovoltaic panels.
When it comes to insulating your home or business roofs, Soltis guarantees quality and compliance with current standards. Contact us for a quote...
