Nailable Polyiso Insulation

Atlas foam roof insulation is well established in the building materials industry through its ACFoam® family of products. Cores of these products are polyisocyanurate (polyiso) foam, the most widely used and accepted rigid insulation in use today. It is estimated that 60-65% of all commercial new or re-roofing applications nationwide use polyiso. Rigid polyiso is a safe, cost-effective, sustainable and energy efficient construction material. All of Atlas nailable polyiso insulation is QualityMarkcm certified, giving consumers an easy way to identify quality products that meet or exceed listed LTTR-values.

Some of the benefits of polyiso insulation are:

  • The highest Long Term R-value per inch of thickness
  • The only roof insulation with third party certification
  • Zero ozone depletion potential (ODP)
  • Negligible global warming potential (GWP)
  • Cost effective solution

ACFoam® CrossVent

Designed for use over unventilated roof decks. CrossVent® allows heat to dissipate while providing a nailable surface and efficient insulation in a one-step labor saving process.

ACFoam® CrossVent RB

What if you could have a prefabricated, ventilating nailable insulation AND a Radiant Barrier? Now you can! CrossVent® RB combines superior R-values with radiant heat protection. Radiant heat is formed when rays of energy from the sun strike an object and transform from motion energy to heat energy. Standard nail base insulation does a good job of reducing convective and conductive heat transfer. However, it does little to reduce radiant heat transfer, which contributes significantly to the total heat flow into the building. Only CrossVent® RB substantially limits Conductive AND Radiant Heat Transfer.

NEW: Techni-Flo Engineered Ventilation Products

techni-flo engineered ventilation systemAtlas Roofing Corporation is proud to introduce the Techni-Flo™ Engineered Ventilation System. Manufactured to meet the design conditions of each project, this state-of-the art ventilation system is engineered to ensure consistent intake and exhaust air flow underneath the roof covering of commercial building applications. Proper venting throughout a steep-sloped roofing system is essential for durability of the roof system and for moderation of roof cover temperatures above the air space.  The Techni-Flo™ engineered ventilation system consists primarily of three components:

  • Atlas Techni-Flo™ EV (eave vent) features a unique design that allows airflow to the eave.
  • Atlas ACFoam® CrossVent® or CrossVent® RB.
  • Atlas Techni-Flo™ RV (ridge vent) accommodates both standing seam and shingled roof applications, and is engineered to individual job ventilation needs.

ACFoam® Nail Base

ACFoam® Nail Base Insulation is ideal for use over sloped solid wood decks having a slope greater than 1/4" per foot. The OSB provides an excellent base for nailing non-asphaltic shingles.
