Thermal Insulation-- green facades can insulate

Well, let's be honest: this is true in the summer where surface greening on the house reduces the heat in the home. A saving on wintry heating cost is only possible if all sides of the house are thickly entwined with ivy. A maximum of 5 - 10% of heating costs can be expected. In a perfect world, no wind would blow, carrying the protective air cushion of the foliage away...

Summer Heat Insulation

When it comes to "thermal insulation," everyone first thinks of cold winters and insulating layers that reduce heating costs. But insulation is also in demand in the summer when walls and interiors heat up excessively in strong sunlight. This is when facade greening can cool down the walls by absorbing the sun's rays and by not allowing the rays to hit the wall surface. This is especially true in non-insulated homes where the greening can replace air conditioning and save your wallet. Facade cooling without electricity costs is at the same time active climate protection- Yes!
