Pergola Materials and Insulation: Metal, Wood and Membrane

How should you insulate metal, wooden and membrane pergolas? Protect every pergola surface against heat, water and UV with ISO THERMAL.

Pergola Materials and Insulation: Metal, Wood and Membrane

Pergolas are made from different materials, and each material has a different weak point. Proper insulation starts with understanding how the material behaves.

Metal and Aluminum Pergolas

Metal absorbs and conducts heat the most. It becomes untouchable under the sun and corrodes over time. ISO THERMAL adheres strongly to metal without a primer, reflects heat, and protects the surface against corrosion.

Wood and Membrane Surfaces

Wood cracks and fades with UV, moisture and temperature swings. Membrane, tarp and polycarbonate surfaces require flexibility. With its elastic structure, ISO THERMAL works on these surfaces without cracking and forms a waterproof layer.

  • Metal: Heat reflection + corrosion protection.
  • Wood: Flexible protection against UV and moisture.
  • Membrane/Polycarbonate: Waterproof, flexible coating.

Whatever the material, one solution: ISO THERMAL. Safe insulation, safe future.
