Question 1

What is a concrete-faced continuous insulation panel?

Accepted Answer

A concrete-faced continuous insulation panel (CI panel) is a composite building product consisting of an insulation core — typically EPS, XPS, Mineral Wool, Hemp Fibre, or ISO — bonded to a concrete face. It provides uninterrupted thermal resistance across the building envelope with no thermal bridging at structural members, meeting ASHRAE 90.1 and IECC continuous insulation requirements.

Question 2

What makes ThermoShield different from other CI panels?

Accepted Answer

ThermoShield uses a proprietary SynStone GFRC/UHPC (Glass Fibre Reinforced Ultra-High Performance Concrete) face instead of the standard latex-modified Portland cement used by other CI panels. SynStone eliminates cracking and efflorescence, provides superior impact resistance, is non-combustible, and is available in multiple architectural textures. ThermoShield also offers five insulation core options — EPS, XPS, Mineral Wool, Hemp Fibre, and ISO — compared to the XPS-only offering of most competitors.

Question 3

What is continuous insulation (CI)?

Accepted Answer

Continuous insulation (CI) is insulation that is uninterrupted across all structural members without thermal bridges other than fasteners and service openings. CI is required by ASHRAE 90.1 and the International Energy Conservation Code (IECC) for commercial buildings to meet energy performance targets. Concrete-faced CI panels like ThermoShield PerimeterShield™ and RoofShield™ provide CI in a single, durable, self-protecting assembly.

Question 4

What is a Protected Membrane Roof (PMR)?

Accepted Answer

A Protected Membrane Roof (PMR), also called an inverted or upside-down roof, places the insulation above the waterproofing membrane rather than below it. This protects the membrane from UV radiation, thermal cycling, and mechanical damage, significantly extending membrane life. ThermoShield RoofShield™ CI panels are designed specifically for PMR assemblies, serving as both continuous insulation and ballast.
