Multi layer foil insulation u value.

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.

A number of multi foil insulation products now come with vapour control layers whilst other multi foil insulation products can also act as a breather membrane or vapour permeable insulation. We manufacture market and distribute reflective insulation and radiant barriers and we re committed to expanding our footprint to advance sustainability cost effectiveness and the energy efficiency of buildings.

Additionally some multifoil insulation products have been combined with other features meaning that one product can be used for several functions. Fi foil is your leading source for sustainable high value advanced performance reflective insulation products and systems. Superfoil is a highly versatile product whilst still maintaining outstanding performance in all applications.

The higher the number of the r value the better it will perform. Insulate internally with just one product which also includes vapour control such as hcontrol hybrid with 38mm batten either side to reach a u value of 0 30 w m2k. The u value measures the efficiency of a wall floor or roof more precisely how different parts of a building are transferring heat. Most brands of insulation have a u value displayed on their products as a matter of pride.

Typical fibreglass insulation for example requires 270mm of insulation to get to a u value of 0 16. Lower u values mean better thermal performance. As well as this superfoil can be used internally or externally to achieve your u value target. We can often find this value attributed to multifoil insulation.
