High insulation value, good water resistance, light weight and low cost make versatile EPS insulation from Insulation Technology, Inc. ideal for use in a variety of single-ply membrane systems and built-up roofs (BUR) used in new construction and reroofing applications.

Built-Up Roofs (BUR)
Over Metal Deck

• Good insulation value, low cost; meets most fire codes and ratings.
• May use EPS/fiberboard composite, or mop and flop fiberboard or per-lite to EPS with asphalt.
• Thermal barrier such as perlite or gypsum board may be factory lami-nated or attached with mechanical fasteners, asphalt or adhesive.
• Use flat or tapered EPS.

Adhered Single Ply
Membrane Re-Roof

• Adds high insulation but little weight to the existing roof.
• Mechanical fasteners penetrate EPS and attach to deck.
• Stone ballast may be used if weight is not a limitation.
• Some membranes require barrier sheet separation from EPS.

Ballasted Membrane Over
Metal Deck

• Long-term performance in a light weight system.
• Span deck flutes and meet code/ insurance requirements with specified underlayment board.
• Flat or tapered EPS insulation panels are loose-laid under membrane.
• Membrane can also be fully adhered or mechanically fastened for a smooth exposed surface.
• Some membranes require barrier sheet separations from EPS.

Tapered EPS for New Roof or ReRoof

• Eliminates ponding; provides positive drainage in new or retrofit roofs.
• EPS insulation manufactured with minimum slope of 1/4" per foot.
• Taped overlayment assures surface continuity.
• Vapor retarder optional depending on environmental conditions.
