Polyurethane Systems for building and industry

Floors insulation

Floors are usually forgotten when it comes to applying thermal insulation techniques, since the insulation of façades and roofs of buildings seems more important. However, a large part of the loss of energy in buildings (up to 20%) occurs through floors, so the use of optimal insulation products in their construction is essential if we seek maximum energy efficiency and inner comfort.

The thermal insulation of floors is conducted by projecting or installing a thermal insulating material on the floors in contact with non-habitable spaces, supported on the ground or in contact with the outside air.

Following the indications of the Technical Building Code, we conclude that the advantages of thermally insulating a floor are mainly:

  • Minimization of energy losses (with consequent energy and economic savings) through the floors of the building.
  • It avoids the risk of condensation and the lack of thermal comfort. The surface temperature of the soil can be much lower than the room temperature, which can cause lack of comfort due to "cold radiation" and the risk of surface condensation.

Insulating the ground floor can save up to £45 - £55 a year, and the gaps between floors and skirting boards can also be sealed to reduce draughts. 

 

Floor insulation: the case of projected polyurethane systems

Projected polyurethane is one of the most used insulation materials in buildings. The spray foam can be directly applied to the concrete base.

The depth of the foam depends on the U-Value requirement. Synthesia Internacional products use 50 mm-70 mm to obtain values among 0.16W/m²K and 0.22W/m²K, which provide an optimal insulation. 

 

Solutions for floor insulation

There are at least three techniques to minimise thermal bridging when insulating floors:

Insulated cavity wall is a good solution because it's the most complete and guarantees the fulfillment of the requirements of energy efficiency. This solution is possible in buildings already constructed thanks to the injected polyurethane.

In case of new constructions, the Foam Spray Insulation guarantees a constant isolation, without cracks or thermal bridges. It is the insulating material more convenient due to its technical characteristics and due to its durability.
