EnergyGuard™

Perlite Roof Insulation


Description


EnergyGuard™ Perlite roof insulation is a homogeneous board composed of expanded perlite particles, selected binders and cellulose fibers, which give EnergyGuard™ Perlite roof insulation its insulating efficiency. The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes.

EnergyGuard™ Perlite roof insulation is available in 2’ x 4’ (0.6m x 1.2m) and 4’ x 4’ (1.2m x 1.2m) boards in standard thicknesses of 3/4”, 1”, 1 1/2”, and 2” (19mm, 25mm, 38mm and 51mm). Other sizes are available on request.


Advantages
  • Stable insulating properties.

  • Exceptional fire resistance (Class 25).

  • Excellent dimensional stability.

  • Resists damage due to normal deck traffic during and after construction.

  • Fast and easy to apply.

  • Tough performance proven for over 30 years.

  • The minimum recycled content is 25% by weight.


Uses
  • EnergyGuard™ Perlite roof insulation is designed to be used directly over structural roof decks.

  • It is also widely used as a separation board over existing roofs in recover installations. In recover applications, all wet areas of the old roof must be removed. All loose and protruding gravel must also be removed.

  • Properly installed, EnergyGuard™ Perlite roof insulation is suitable for use under built-up, modified bitumen and some single ply roofing systems.

  • Refer to the current membrane manufacturer’s application and specifications manual for proper installation procedures for perlite roof insulation.


Limitations
  • EnergyGuard™ Perlite roof insulation is a non-structural, non-load bearing material.

  • EnergyGuard™ Perlite roof insulation should be stored dry and be protected from the elements. Once properly loaded at the job site, remove factory wraps and cover with a breathable tarp.

  • No more insulation should be applied than can be completely covered with the finished roofing on the same day.

  • Do NOT use under fully adhered single ply systems or with direct torch application of modified bitumen.

  • If torch grade modified bitumen roofing is to be installed over EnergyGuard™ Perlite, a fiberglass base sheet MUST first be installed.


Code Compliance
  • EnergyGuard™ Perlite complies with the requirements of ASTM Standard C728 (which supersedes Federal Specifications HH-I-529).

  • Listed by Underwriters Laboratories for use under Class A, B or C Roof Covering. See UL, ULC Roofing Materials and System Directory for details.
    Materials will have UL, ULC labels only when specified on order.

  • Factory Mutual rated for fire and wind resistance. For current approvals, see current Factory Mutual Approvals Guide.

  • Is approved for use in UL, ULC Fire Resistance Roof-Ceiling Design (P&R-Designs). Please see the UL, ULC Roofing Materials and System Directory for the latest approvals.

  • Complies with the Environmental Protection Agency Regulation 40 CFR Part 248, “Guideline for Federal Procurement of Building Insulation Products Containing Recovered Materials,” as a recycled product approved for use on any project using federal funds.

NOTE: REPAIR ROOF LEAKS PROMPTLY TO AVOID ADVERSE EFFECTS, INCLUDING MOLD.
