We fit an insulation which is  ultra-thin, multi-reflective with 4 layers of aluminium multi-layer insulation material which is thermally-welded across all its surfaces.  
 
  1. A film of pure aluminium, 30 microns thick, treated against oxidation
  2. A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
  3. A film of pure aluminium treated against oxidation
  4. A foam of fire-retarding and waterproofed polyethylene
  5. A film of pure aluminium treated against oxidation
  6. A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
  7. A film of pure aluminium, 30 microns thick, treated against oxidation

The air trapped in the bubble film and polyethylene foam is dry and stable. Possible condensation is therefore always avoided within the usual range of temperatures for these type of insulations.

U-Value of less than 0.5 W/m2K 

See the table below which outlines the U-Value each of the materials below provides: Remember the lower the U-Value the better
