- Helps control vapor movement into insulation
- Supports reflective heat insulation design
Aluminium Laminated Membrane
- Foil surface for reflective insulation support
- Backing options with film, woven fabric, nonwoven or mesh
- Roll width and packing can be confirmed before order
Factory Supply Support
- Samples before bulk order
- Technical file and packing photo available
- Quotation based on structure, roll size and quantity
Vapor Function Check
Reflective Housewrap and Vapour-Permeable Membrane Are Different Constructions
Vapour-Permeable Housewrap
Exterior walls that need outward drying normally use a tested vapor-open WRB or housewrap behind cladding. Water resistance, vapor permeance, lap sealing and drainage details should be reviewed together.
Reflective Foil Vapor Barrier
A continuous aluminium foil facing is generally selected as a low-permeability vapor-control and reflective insulation layer for steel roof assemblies. It should not be described as a vapor-open membrane unless the selected construction and test data confirm it.
Confirm the roof build-up, insulation location and condensation-control requirement before selecting the roll structure.
Technical Notes
Reflective vapor control for steel structure roof insulation systems.
Aluminium foil vapor barrier is used as a reflective and low-permeability layer in metal roof insulation assemblies. It helps reduce vapor migration into insulation and supports cleaner roof build-up when overlap, sealing and fastening details are controlled on site.
Technical Data
Key Data to Confirm Before Quotation
Material Structure
Common structures include aluminium foil laminated with PE film, woven fabric, nonwoven fabric or reinforced mesh according to the required roof insulation system.
- Foil surface and backing structure
- Weight, thickness and roll width
- Roll length, packing and pallet details
Installation Notes
For vapor control performance, overlap and joint sealing details are important. The final layer position should be confirmed according to local roof design and condensation requirements.
- Keep rolls clean and dry before installation
- Control lap direction and sealing tape details
- Avoid tearing around fasteners and edges
