DOW Thermax Sheathing™ from Dynamic Composite Technologies

Dow Thermax Sheathing™ is a non structural, rigid board insulation consisting of a glass fibre-reinforced PIR foam core laminated between 1.0mm smooth, reflective aluminium foil facers on both sides. The glass-fibre reinforcement, along with chemical modifications, contribute to improved fire performance and dimensional stability. The bonded aluminium foil facers serve as effective moisture vapour retarders.

Dow Thermal Sheathing™ and Metal Building Board insulation products have aluminium foil facers on both sides. Dow Thermax Sheathing™ Light Duty and Heavy Duty insulation products have an aluminium foil facer on one side with a white coated facer on the other. This design is an aesthetically appealing decorative effect.

Dow Thermax Sheathing™ can be installed exposed to the interior without a thermal barrier which offers a high insulating value and is ideal for installations in attic's and exposed roof applications without a thermal barrier.

Boards of Dow Thermax Sheathing™ are lightweight and can be sawed or cut with a knife. They install quickly to walls and ceilings - inside and outside of purlins, trusses or bar joints. Butt joints must be installed over structural members.
