Over 37,000 houses across Europe have been retrofitted to Passivhaus standards. The families typically experience 90% heating energy savings. You do not need a boiler except for hot water and peace of mind.
The reason why only 37,000 families across Europe currently enjoy these benefits is due to the large thickness of insulation required. 3rd Way Super Insulation has overcome both thickness and cost barriers and now enables anyone to enjoy Passivhaus benefits.
A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction to provide better insulation performance than conventional insulation materials.
