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. It is a high water barrier, medium vapour barrier product, ideal for steel roofs. It provides extra R-value from inward and outward facing reflective surfaces when used in conjunction with adjacent air spaces.
- 1350mm x 19m (25m2)
- 1350mm x 56m (75m2)
Buildings of the following types using metal cladding should have a sealed vapour barrier and are subject to specific design.
- Swimming pools.
- Buildings containing liquids stored in open containers.
- Buildings where water is used in manufacturing, cleaning or storage processes.
- Ice rinks, cold stores and freezers.
- Buildings where unvented gas heating is used.
A vapour barrier incorrectly located on the cold side of a structure or poorly installed can result in a rapid build-up of cavity or interstitial condensation and result in high costs for rectifying defects and damage.
Cold stores, freezers or buildings where the temperature is near or below 0° all require a fully sealed vapour barrier located on the warmer outer side of the insulation but are subject to specific design.
