Orac Decor products are primarily designed for decorative applications, and their thermal insulation capacity is limited. However, they can make a modest contribution to the thermal insulation of a space due to the nature of the materials used. Here is an analysis of their thermal insulation properties:

Materials used and thermal insulation

1. Purotouch® (high density polyurethane) :

   • This material has low thermal conductivity, which gives it a slight insulating capacity.
   • It can help limit heat loss when used on cold surfaces (such as exterior walls).

2. Duropolymer® (high density polymer) :

   • This material is also a modest thermal insulator due to its density and composition.
   • It may slightly reduce heat transfer, especially when used as a skirting or surround.

3. Durofoam® (lightweight expanded polystyrene) :

   • Expanded polystyrene is known for its insulating properties, although Orac Durofoam products are primarily intended for decorative applications and do not offer sufficient thickness for significant thermal insulation.

Potential contributions of Orac products

• Reduction of thermal bridges :
  • Mouldings, cornices and baseboards can help to mask or cover areas where thermal bridges are present (for example, between a wall and a ceiling or floor), thereby reducing heat loss through these points.
• Dubbing effect :
  • When installed on walls or ceilings, Orac products can provide an additional barrier, although they are not designed to function as primary thermal insulators.

Limits in terms of thermal insulation

• Thickness and density :
  • Orac products are relatively thin and light, which limits their ability to significantly reduce heat exchange.
• Not designed for insulation :
  • They are not intended to replace specific insulating materials, such as mineral wool, expanded polyurethane panels or foam-based insulation.

To improve thermal insulation

1. Combination with insulating materials :
   • Orac products can be used in addition to insulation panels to improve the aesthetics of spaces without compromising thermal performance.
2. Use in heated spaces :
   • They can be installed in heated rooms to reduce temperature variations without altering the decorative appearance.
3. Protection against drafts :
   • Baseboards and moldings can help provide a better seal by covering cracks or gaps where air could circulate.

Conclusion

Orac Decor products offer limited thermal insulation properties and are not designed as thermal insulators. However, they can complement an overall insulation system by improving sealing and providing a slight insulating effect thanks to their materials. For optimal thermal performance, it is recommended to combine them with specific insulating materials.
