Insulations & Cover Boards

Sarnatherm Insulation (25 psi)

Sarnatherm 25 psi is a rigid insulation board with paper facers. Sarnatherm is installed directly on the roof deck or directly on the old roof surface prior to application of the Sarnafil membrane.  The core of Sarnatherm is isocyanurate foam. The standard paper facer contains recycled materials and fiberglass-reinforcement for dimensional stability.

Sarnatherm® Tapered (25PSI)

Sarnatherm® XPS Insulation

Sarnatherm XPS is a rigid extruded polystyrene insulation board. Sarnatherm XPS is installed either under or over the Sika Sarnafil roofing/waterproofing membrane depending on the system design.

Sarnatherm® XPS Tapered

Sarnatherm XPS - Tapered is a rigid extruded polystyrene insulation board.  Sarnatherm XPS - Tapered is installed either under or over the Sika Sarnafil roofing/waterproofing membrane depending on the system design.

Securock® Glass-Mat Roof Board

Securock is a rigid fire-tested roof board used with or without insulation as an overlayment or thermal barrier under a Sika Sarnafi l mechanically attached roof. Securock is a homogenous fiber reinforced gypsum panel that is moisture resistant. Together these materials provide dimensional stability and thermal protection of the structural deck, insulation and Sika Sarnafil membrane.

DensDeck® DuraGuard™ Roof Board

DensDeck DuraGuard is a rigid fire-tested roof board used with or without insulation as an overlayment or thermal barrier under Sarnafil roof membranes. DensDeck DuraGuard is specially designed for self-adhered membranes.  DensDeck DuraGuard is a non-structural, coated glass-mat faced, moisture resistant, treated gypsum-core panel. This treated gypsum core is an integral part of the glass mat surfacing on both sides. DensDeck DuraGuard has a low perm, blue colored surface treatment which provides a stronger bond for adhered membrane applications. Together these materials provide dimensional stability and thermal protection of the structural deck, insulation and Sarnafil membrane.
