About Toprock® Tapered, Flute Filler and Cant Strips

ROCKWOOL Toprock® Tapered, Flute Filler and Cant strip fabricated components are cut from high-density stone wool roof insulation that will not warp or cup. The low co-efficient of linear expansion of this material means less movement during temperature changes and no shrinking over time that could otherwise cause energy loss.

Toprock Tapered products are available with and without a bitumen facing, and are engineered to ensure positive drainage and avoid ponding.

Toprock Flute Filler inserts into the void of standard metal deck profiles to absorb noise and incidental sound.

Toprock Cant strips are available with a bitumen coating to provide transitions from horizontal to vertical surfaces.

  • Noncombustible and fire resistant
  • Dimensionally Stable
  • Sound Absorbent
  • Water Resistant
  • Ease of Installation
  • Stable R-value

Why use stone wool insulation

  • Noncombustible and fire resistant, stone wool works to contain a fire and prevent its spread.
  • Stone wool will not expand or contract with changes in temperature, minimizing gaps and providing consistent energy efficiency for your building.
  • High-density insulation offers improved sound reduction, helping dampen outdoor noise and rainfall.
  • Will not absorb or adsorb moisture and increases the drying potential of the assembly.
  • Cuts easily and cleanly with a serrated blade to produce precise, straight lines and lays flat with a seamless fit.

Applications

  • Designed for low-slope roofing applications to support full assembly design.
  • Compatible with a variety of membrane types, air/vapor barriers, fasteners, and adhesives.
  • Can be used in both new construction and re-roofing applications.
