Mineral wool board DOORHAN “LIGHT EXTRA”

DOORHAN LIGHT EXTRA mineral wool slabs are used as unloaded thermal insulation of horizontal, vertical and inclined building envelopes of all types of buildings, including for the construction of floors, ceilings, and internal partitions.

Application:

Warming of a private house
Floor insulation along the lags

Order with installation

Advantages

The raw material for the production of plates is natural stone. The products meet all the requirements for environmental friendliness, which is confirmed by the relevant certificates.

The excellent heat-insulating properties of mineral wool significantly reduce heat loss.

Hydrophobic impregnation of cotton wool forms a film on its surface, which prevents the penetration of liquid inside, while not blocking the natural circulation of air.

Mineral wool is a non-combustible material and helps to maintain the integrity of the building in the event of a fire.
