Product: THERMAX Insulation Sheathing

Applications: 

Applications Light Duty THERMAX:

For walls and ceilings in:
metal, wood post frame in concrete or masonry buildings

Light Duty can be pressure washed up to 6,894.7 kPa with a 15 degree or greater spray tip.

Applications Heavy Duty THERMAX:

High impact interior finish for walls in:
metal, wood post frame in concrete or masonry buildings

Heavy Duty is a durable choice for use in moderate impact areas. When applied in conjunction with appropriate joint closure system, THERMAX Heavy Duty PIR thermal insulation with its low perm rating helps decrease moisture condensation within and behind the insulation.

Heavy Duty can be pressure washed up to 2,000 kPa with a 15 degree or greater spray tip.

About the Product: THERMAX insulation sheathing (distributed by DCTech) was designed as a thermal insulation and interior finish system. It is a non-structural, rigid board consisting of glass fibre reinforced polyisocyanurate (PIR) thermoset foam core laminated between smooth, reflective aluminium foil facers on both sides. The bonded aluminium foil facers serve as moisture vapour retarders.

The core, along with chemical modifications contribute to improved fire performance and dimensional stability. It will not melt, flow or drip when exposed to fire, it forms a char to prevent flame spread and further degradation to the core. This is unlike Expanded Polystyrene (EPS) which will spread due to the oxygen being held between cells, EPS is thermoplastic so it will melt and shrink under heat pressure.

General Installation Advice:

THERMAX can be installed to exposed interior without a thermal barrier therefore it holds a high insulating value.

THERMAX is manufactured with zero ozone depleting potential (ODP) therefore it decreases the carbon footprint of commercial buildings.
