They have a high vapour resistance so may also function as a vapour control layer.
Multi layered thermal reflective insulation.
We have several multi layer reflective insulation products to meet different installation methods and applications.
All of our products are designed to help improve the performance of mass insulation by increasing the thermal efficiency and reducing radiant conduction and convection heat transfer.
Given this alternative approach to thermal performance specifiers now need to consider surface emissivity and thermal resistance when specifying thermal insulation products.
Nasa scientists have discovered that a thin layer of aluminum can insulate as well as a 7 foot thick piece of conventional insulation.
Multi layer insulation mli is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics it is one of the main items of the spacecraft thermal design primarily intended to reduce heat loss by thermal radiation in its basic form it does not appreciably insulate against other thermal losses such as heat conduction or convection.
Multi layer reflective foil insulation is recommended for use in a range of applications.
Their installation typically relying on the need for an adjoining cavity facing the surface reflective foil.
The reflective technology integral to multi layer insulation can assist in reducing thermal losses from buildings.
