Radiant Barriers
Aluminium radiant barrier
Many radiant barriers are made of metallised surfaces, which reflect about 50 to 60% of heat radiations. Our MONIER radiant barrier is a pure aluminium foil with a minimum radiation reflection of 95% (and up to 99%).
In addition our extensive Research and Development activity allowed us to innovate, producing a high density polyethylene woven structure. This synthetic structure is much more resistant to moisture than paper based foil and is highly resistant to tears.
As the main goal of our radiant barriers is to protect Indian buildings from external heat, only the external face is reflective to the radiation.
It is highly advised to use our radiant barriers along with a ventilation system in order to evacuate the heat accumulated between the barrier and the tiles:
- Over ridges, the use of compactroll is the most elegant and efficient way to exhaust the hot air.
- On eaves, either a filler comb or ventilation tiles will be perfect to ensure the entry of fresh air.
Technical information
Our Woven AL Radiant barrier is a 3 layer radiant barrier, using 1 layer of pure aluminium foil bonded to 1 layer of extra strong woven fabric.
It is packaged as roll of 62.5 m2 (1.25m*50m).
For watertighness application, a minimum overlapping of 200 mm is required and specific aluminium tape must be used between rolls.
Main characteristics :
Grammage : 100±15 g /sqm
Tensile : MD = 350 to 400 N/50 mm, CD = 100 to 200 N/50 mm
Elongation : 15±5 %
Force at break : 100±20 N
Water vapour transmission rate <1 g/m2/day
Emittance of surface Aluminium foil : 97±2 %
Woven AL Radiant barrier is manufactured in a Monier Group factory in Malaysia. It is also sold under the RadenShield™ brand name.
