The "power bar" against energy losses

People used to think that house walls must be sturdy and look attractive. Today, energy considerations and also questions of fire and sound insulation play a role in addition to these classic features. Innovative masonry made of sand-lime bricks, bricks, aerated concrete or special insulation stones made of pumice can transform your new building into an energy-saving construction from the start. Using modern construction materials, monolithic walls can be erected which do not require additional insulation systems, and yet still achieve exterior wall insulation values at passive house standards.

Insulating honeycomb for passive house values

With a thermal insulation value of 0.070 W/m2K, mineral energy-saving stones delight house builders today. Without additional insulation or thermal insulation plaster, walls made of aerated concrete can still achieve the passive house standard (U-value up to 0.135 W/m2K)!
The secret: special insulating honeycomb material, filled to fit perfectly with moulded pieces made from mineral wool. These energy-saving stones also make composite thermal insulation systems superfluous.

Aerated concrete is sturdy and provides ingenious thermal insulation

Aerated concrete is not just a particularly sturdy and yet lightweight construction material which can be quickly processed, but also a highly effective insulation material. Due to its extremely low thermal conductivity, it guarantees minimum thermal bridge losses. Special thermal bricks combine the advantages of the aerated concrete construction with “integrated” thermal insulation.

Sturdy bricks, healthy living climate

For thousands of years, people have built houses using bricks of fired clay, a building material with maximum biological construction value. Bricks are extremely robust, with good thermal insulation properties. Bricks adsorb the moisture generated in living spaces and emit it again outwards. Bricks are also excellent as fire and sound insulation protection.

Filled bricks – true “energy bars”?

Bricks filled with Perlite or mineral wool improve thermal insulation properties and make your new building fit for the energy requirements of the future. Even with single-shell wall constructions without additional thermal insulation, they can achieve superb U-values, and with wall thicknesses of 49 cm, they can even achieve passive house standards.

Pumice stone walls with hard foam core

Monolithic masonry made of pumice can also feature insulation qualities up to passive house standard. This is the case, for example, if the stones are filled with a thermal insulation hard foam core. These stones convince customers with a U-value of 0.15 W/m2K at a wall thickness of 42.5 cm.

Working with Nature for optimum living quality

Masonry systems made of natural pumice and lime combine static and biological construction advantages. They achieve peak thermal insulation without a composite thermal insulation system, provide a good living climate and suppress the formation of mould in interiors. In particular interior wall stone made from this mixture of materials also fulfils special sound insulation requirements for load-bearing and non-load bearing walls.

Put your faith in sand-lime brick

A stone with sound insulation properties? This also exists. Sand-lime stone is a brick with a high gross density which combines load-bearing capability with excellent sound insulation properties. It is therefore ideal for use in flat and house partition walls, where, thanks to a mineral additive, it protects not just against noise, but also against electrosmog.

Wall looking for permanent relationship...

Brick walls must be well connected to any existing walls; the so-called “butt joint” is the most up-to-date technology in use so far. Special, particularly thin but highly robust wall connectors add stability to the masonry. The wave shape of this special equipment guarantees excellent extraction values in all stone-mortar combinations; the rounded edges minimise the risk of injury for the person conducting the work.
