Product Description

Product Description

The product is a flexible composite consisting of a black fiberglass veil (270 g/m2) continuously bonded to a 40-micron aluminum foil. It is intended to act as an acoustic vapor barrier behind perforated steel decks or perforated interior facings in metal roof and double-skin facade systems. In terms of use case, it aligns with market references such as the "Rocksourdine" family, while allowing variations in veil grammage, foil thickness, and roll dimensions for OEM supply.

FAQ

1. What is Multi foil Insulation?
Multi foil insulation is a high-performance reflective insulation made from multiple layers of aluminium foil, Metal-coated film,foams, and non-woven materials. It reduces heat transfer through reflection and thermal resistance, improving energy efficiency in roofs, walls, and floors.
2. How does Multi foil Insulation work?
Multi foil insulation works by reflecting radiant heat back into the building while reducing convection and conduction. Its layered
structure creates enclosed air spaces that trap heat and improve thermal resistance (R-value).
 3. What are the main advantages of Multi foil Insulation?
Key advantages include high thermal efficiency, lightweight and flexible installation, vapor control, reduced condensation risk,and long service life. It's also thin compared to traditional insulation, making it ideal for retrofit projects.
4. Where can Multi foil Insulation be used?

It can be installed in pitched roofs, flat roofs, timber frames, loft conversions, walls, and floors. It's suitable for both new
buildings and renovation projects across residential, commercial, and industrial sectors.
5. Is Multi foil Insulation waterproof or breathable?
There are two main types: vapor barrier multi foil (non-breathable) and breathable multi foil (vapour-open). The choice depends on the building system—use vapor barrier multi layer for internal insulation and breathable types for external roofing applications.
6. What standards does Multi foil Insulation comply with?
High-quality multi foil products are tested to EN 16012 for thermal performance, EN 13984 for vapor barrier membranes, and EN 1928 for water tightness (W1/W2 levels). Many also meet CE marking requirements for use in European markets.
7. How thick is Multi foil Insulation and what R-value can it achieve?
Depending on the number of layers (e.g., 9-layer, 19-layer, or 25-layer systems), thickness typically ranges from 25 mm to 50 mm.R-values vary between 1.5 m²K/W to 3.0 m²K/W, depending on configuration and installation method.
8. Can Multi foil Insulation replace traditional insulation materials?
Yes, in many applications it can replace mineral wool or foam board when space is limited. However, in some cases it's used in combination with other insulation types to meet specific U-value or building code targets.
