Wide Variety

A Solution for Any Situation

insulation-coverboard-2

 

IB single-ply roof systems are tested and approved for use over a large variety of high-performance, rigid thermal roof insulation boards, coverboards, and recover boards for maximum design versatility and efficiency.

IB Energy Board II and Energy Board III insulation products are sustainable options constructed from thermally efficient, high R-value polyisocyanurate cores with strong durable facers.

Advantages of Coverboards

Coverboards add an extra layer of protection and insulation, helping shield installed insulation and can assist with interior temperature and humidity regulation.

Additionally, coverboards can help a roof system achieve a specified fire or weather rating such as Very Severe Hail (VSH).

Smooth Top Surface

Coverboards prepare a smooth top surface for applications.

This smooth surface enables consistent adhesion of the membrane, and in-between the insulation boards.

Extra Layer of Protection

Coverboards provide an extra layer of protection against strong winds, fire damage, and wear and tear.

Having a coverboard allows trades to walk on the roof during installation, protecting insulation from punctures.

Maximize Investment

Coverboards maximize your clients’ insulation investment. The durable and long-lasting coverboards protect the insulation from external damage, thus extending the life of these energy-efficient roofing systems.

Control Water Flow

Tapered boards are an option offered in a variety of slopes that can be cut and installed to achieve positive water drainage.
