The greatest thermal losses in a building are usually through the roof, which is why national and European regulations are stricter regarding roof insulation compared to other structural elements of a building.

Depending on the type and use of the building, thermal insulation using Expanded Polystyrene (EPS) can be applied in three ways:

• Horizontally slab. on the last floor.

• Externally, above the rafters.
  • The use of a vapor barrier on the underside of the EPS is recommended for protection against the humidity of the interior space, as well as a breathable membrane for the tiles to prevent moisture penetration due to tile failure or heavy rain..  
• Internally on the roof.
  • This type of application is recommended for upgrades/renovations. The EPS insulation is placed in the intermediate spaces of the rafters. If the roof is visible, a gypsum board/particleboard or wood lining is applied under the EPS for an aesthetic finish.

To select the appropriate solution for your building and choose the right materials for insulation, you should request reliable information from the technical support department of your company.
