Orac Decor products are primarily designed for decorative applications, and their thermal insulation capability 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, giving 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 can slightly reduce thermal transfers, especially when used as baseboards or trim.

3. Durofoam® (lightweight expanded polystyrene):

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

Potential Contributions of Orac Products

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

Limits in Terms of Thermal Insulation

• Thickness and Density:
  • Orac products are relatively thin and lightweight, limiting their ability to significantly reduce thermal exchanges.
• Not Designed for Insulation:
  • They are not intended to replace specific insulation materials, such as mineral wool, expanded polyurethane panels, or foam-based insulation.

Improving Thermal Insulation

1. Combination with Insulation Materials:
   • Orac products can be used in conjunction with insulation panels to enhance 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 aspect.
3. Protection against Drafts:
   • Baseboards and mouldings can contribute to better sealing by covering cracks or spaces 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 due to their materials. For optimal thermal performance, it is recommended to combine them with specific insulation materials.
