Our houses are setting records in furnishing and energy consumption savings.
The VARIANTHOUSE system is simple and ingeniously constructed. Instead of exorbitant scaffolding and form dismantling plus subsequently insulating the finished walls, our Neopor® elements are the formworks and insulation at the same time. And these elements are as easy to fit to each other as "Lego blocks" and are provided with naps and grooves that click into each other and that are subsequently filled with concrete.
That results in unbroken insulation without thermal bridges; using our “13.7 inch exterior wall blocks" for the formed wall achieves the nearly perfect u-value mark of 0.15 (W/m²u)! As a result, any house builder can realize the dream of an own home at a high technical standard even without craftsmanship skills and save up to 40 % as compared with customary masonry wall construction.
Whereas usually an average of more than 5.6 gallons of heating oil (corresponds 26 cubic yards of gas) are used per year, with our 13.7 inch block elements you can erect a so-called "low-energy or LO-CAL house" that only consumes ca. 1.32 gal/yd³ heating oil (corresponds to 5 yd³ gas) per year!
An additional reduction of the energy consumption even up to a "passive house“ that makes-do without any customary heating system is perfectly possible with our 17.7 inch block elements.
Take a look at the above explanation of our block formats. However, the energy consumption of a "passive house" can only be obtained with a high degree of insulation expenditure, meaning a u-value of 0.10 (W/m²u) (R-Value 10), very good windows with a u-value of 0.5 (W/m²u) (R-Value 2) and a special ventilation and heat reclamation system. The extra costs for a passive house currently add up to about 20 % higher construction costs. |
