КERAPLAST OY is engaged in production of hatches of smoke removal systems and translucent domes for more than 30 years and plays first violin in this area.

All products correspond to the European norms and rules, certificated in the category ISO 9001:2000.

Transparent light domes let send light in premises that otherwise would be subject to artificial illumination. The typical buildings for use of light domes are as follows: buildings with a wide roof, underground structures, passages between buildings etc.

Light transparent domes let send in premises twice as much daylight than wall windows of the same size because skylights receive the light of whole firmament. It is better to use them on flat roofs, where the depth of light shaft is from 1 to 2 meter.

The hatches of smoke removal are assembled in ceiling portion of the building and intended for formation of free of smoke area at the bottom of premises so that provide conditions for safe evacuation of people and effective work of rescuers. There are four types of hatches design; hatch covers are both transparent and opaque. There are 24 normals of hatches. Dooms and hatches bases have the same design.
