Paraboard® HD

Siplast Paraboard® HD is an asphaltic panel composed of a high-density closed cell polyisocyanurate foam core with an SBS-modified bitumen base sheet laminated on top. These high-performance panels are designed to be used as both the coverboard and base membrane layer in a modified bitumen roofing system and are suitable for use in roofing applications where thermal insulation and durability are essential. In certain applications, they may be used as temporary roofing during repairs and new construction Paraboard® HD helps save on installation time and labor, as it eliminates the steps required to individually adhere roof components below the cap sheet membrane. They can be installed using mechanical or adhered attachment methods.

Available in Canada only.
