DriStud F3 - Fire Retardant Double Sided Foil
DriStud F3 is a standard weight, fire retardant, medium duty, double sided reflective foil insulation, designed for use as insulation and condensation control under metal in commercial and industrial buildings.
High water barrier, medium vapour barrier product, ideal for steel roofs.
Provides extra R-value from inward and outward facing reflective surfaces when used in conjunction with adjacent air spaces.
Scope of Use
DriStud F3 is designed for use as a commercial roof and roof sarking in commercial and farm buildings in all regions of New Zealand.
Durability may be affected by environmental factors, including airborne pollutants, if used in industrial or farm buildings.
The outer construction envelope of this product should be installed the same day as the metal roof.
To ensure optimal thermal insulation performance, as well as satisfactory durability, a 25mm air space adjacent to the foil side of the product is recommended.
Limitations on Use
DriStud F3 is not designed to withstand prolonged direct exposure to the elements.
The Aluminium Foil should not come into contact with wet concrete or mortar, as the aluminium is susceptible to alkali corrosion.
