Heat Insulation

Based on the different load and thermal management requirements, Domer manufactures polycarbonate multiwall reinforced and stable structures to meet the various options of clients’ needs.
We provide specific solar control performances reducing the solar heat gain while securing high levels of healthy natural light passing into the building.

Domer Multipoll structured multiwall polycarbonate sheets are lightweight compared to solid polycarbonate sheets or glass, offering far better thermal insulation in a single panel.
Perfect to pass the light while keeping the heat out in summer; likewise, pass the light into the living space while preserving the heat within the building in winter.

Product Benefits:
  • Lighter weight than glass and solid polycarbonate sheets
  • Excellent impact strength
  • High light transmission and variety of tints
  • Flame retardancy
  • Excellent print quality and ink adhesion
  • Weatherability: Co-extruded UV layer on one or both sides

Would multiwall polycarbonates lose color over time?

Domer Duratherm panels are co-extruded with premium quality UV resistant layer guaranteeing very long life expentancy without color fade or change.

Can we install polycarbonate multiwalls horizontally for siding?

Multiwall polycarbonates have hollow structures that should be installed vertically for outdoor applications, places with high-temperature differences, humid areas, and so on, to allow water to drain out.

However, in some interior dry applications, multiwall polycarbonates can be installed horizontally.
