MEGAMAT LTD was established in 2002 with a main priority of improving the energy - efficiency of housing. The beginning of this activity was set in 1993 when our partners introduced in Bulgaria the seamless polyurethane insulation of buildings. We used the experience we collected through the work with the best insulation material and the seamless technology of its application for the development of innovative products and techniques in the field of construction.

MEGAMAT LTD specializes in the production of one and two - storey passive family houses.

The term “Passive House” refers to buildings which obtain more than 90% of the necessary energy for heating in a passive way, i.e from solar rays coming through the windows and the heat radiated by household appliances and the occupants of the home. The annual consumption of energy for heating of such a building is less than 15 [kWh] per m2. The special ventilation of the house provides constant exchange of air as well as energy recovering and heating of the always fresh and rich with oxygen incoming air. The cosy inner climate created with minimal energy consumption is healthier and this is one of the significant advantages of the passive house.

The minimal quantity of energy needed for heating and cooling the passive house is obtained passively, i.e. by means of solar and earth collectors, accumulating containers etc. In terms of energy balance and the amount of energy supplied by an outer source, passive houses can be:

zero house - a house which is completely independent of the electrical grid and

plus house - a house which produces more energy than it consumes by means of a solar photovoltaic system.
