High-Performance Warm Roof Solutions

Gunac delivers high-performance warm roof solutions designed to enhance thermal efficiency, reduce maintenance, and extend the life of your building.

What Is a Warm Roof?

A warm roof system places insulation above the structural deck, keeping it within the warm zone of the building. This eliminates condensation risk, improves thermal performance, and significantly extends the lifespan of the waterproofing membrane above.

Key Benefits

  • Improved thermal performance — retains heat, reducing energy costs
  • Enhanced drainage — tapered PIR boards reduce ponding
  • Reduced maintenance — long-term durability and fewer repairs
  • Retrofit-ready — adaptable to existing roof structures
  • Asset value uplift — adds long-term value to your property
  • Moisture control — breathable design prevents internal dampness
