Thermal insulation improvement of the system MasterLine 8 (U_f-value down to 0,76 W/m²K)

It has a Passiv House component certificate. Founded in Germany (Darmstadt), the PassivHaus Institut created a specific construction standard for buildings which have excellent comfort conditions in both winter and summer. These principles can be applied not only to the residential sector but also to commercial, industrial and public buildings. Passive House buildings are extremely energy efficient: they have energy savings upto 90% to existing housing. They are also designed to be very comfortable, healthy and sustainable. With the Passive House concept the heat loss that typically takes place in buildings through the walls, roof and windows is drastically reduced, by applying five basic principles:

• high-quality thermal insulation

• windows with triple glazing

• avoidance of thermal bridges

• an airtight building envelope

• a ventilation system with heat recovery

Such buildings are called "passive houses" because a major part of their heating demand is met through "passive" sources such as solar radiation or the heat emitted by occupants and technical appliances.

It also has a Minergie module certificate. Minergie is a Swiss sustainability label for new and refurbished buildings. Comfort is at the heart of this label: the comfort of the users living or working in the building. This level of comfort is made possible by performing building envelopes and the continuous renewal of air. Minergie modules are selected and certified components and component systems in Minergie quality. They are the building blocks of the Minergie house, yet the use of Minergie modules is not mandatory. In addition to aspects of energy consumption, modules also meet other important criteria: usability, mechanical strength, ease of maintenance and economy.

• Max. width vent 1,2 m, max. height vent 2,8 m, max. weight vent 200 kg, max. glass thickness 88 mm

• Usually not used for low-cost family houses. Solid sub-construction (concrete, bricks, solid wood, steel etc.) required. In standard version it cannot be used as a fire protection structure, but could be done on project basis.
