Thermoseal® 753 HD is a Heavy Duty sarking-type product for use under commercial metal deck roofs, and in commercial and residential walls. It is a reinforced paper based reflective aluminium foil and semi-reflective antiglare foil laminate; bonded using a fire-retardant adhesive. This product is a Water Barrier and Class 1 Vapour Barrier
Thermoseal reflective foil roof sarking is a non-permeable, vapour barrier product designed to reduce the transmission of moisture into the home and contribute a reflective air gap R-Value to the roof system when positioned to adjacent to an inward or outward facing air cavity.

Key product features:
- Improves the R-Value of the roof system by contributing a reflective air-gap R-Value – this can be up to RT1.8 (summer heat flow down down)
- Reduces the transmission of water vapour through the building structure*
- Improves energy efficiency by reducing draughts allowing insulation to work more effectively
- Protects the building frame from decay by reducing the entry of wind driven rain and dust.
