LOW ENERGY HOUSES:

What exactly is a low-energy house?

Low energy houses are called heated buildings, where the need for heating provided by one of the standardized calculations and with respect to 1m2 of floor area heated does not exceed 50 kWh per year.

Low energy VELOX

The low demand for heating of houses built with VELOX technology are the result, not only of the excellent thermal insulation properties of walls with optional insulation of up to 200 mm, but also the accumulation and thus the thermal inertia of the walls several times higher than conventional building materials.

This combination allows you to accumulate heat from sunlight through glazed areas during the day and in the evening return it back into the living space. This has a reverse effect in the summer where accumulated evening and night time cold air helps maintain a pleasant room temperature without additional air conditioning.

Unique properties of the Velox Building System

THERMAL
THERMAL
Velox panels have optimal thermal insulation properties. This results in a living environment that is naturally warm in winter and cool in summer – even in extreme temperatures, and compared to traditional building methods requires minimal heating.

THERMAL
STABLE
Velox boards are especially stable under load and are particularly resistant to warping and bending. A Velox build forms a rigid structure that won't crack, creak or distort.

SOUND OPTIMAL
Velox boards have optimal sound insulating properties. Interior sound is echo-free and exterior sound is extremely well insulated. Velox is often employed specifically for its sound insulation – as noise barriers near motor- ways for example.

FIRE RESISTANT
Velox is naturally flame retardant and boasts excellent fire resistance. In tests according to the ÈSN 73 0862 classification of the flammable levels of building materials Velox achieved a 'B' grade - 'hardly flammable'.
