Foil Insulation

Yuzet® foil is one of the UK’s bestselling insulation foils. It can be used for many different insulation purposes and it is easy and quick to use and install.

We offer two kinds of insulation foil: Radiator Foil and Triplex Laminate with a layer of bubble foil.

Our radiator foil consists of one layer of aluminium and one layer of foam. It gets installed on the wall behind a radiator and helps to reflect heat back into the room. The use of foil behind radiators (especially on external walls) helps conserve valuable energy and reduces heating costs significantly and for the long term.

Our triplex laminate consists of a centre layer of bubble foil that has been lined with aluminium foil on both sides. It can be used to insulate roofs, walls, dry linings, greenhouses, garage doors or flooring. The individual layers preserve warmth in winter and reflect it in the warmer summer months, thus ensuring that room temperature remains constant year-round. The R-value of our triplex laminate is 0.88m2K/W.

What is Foil Insulation?

There are three main types of Yuzet Foil Insulation. Single laminate, Double Laminate and Radiator Foils. These are all used for very different applications.

The foil starts life in sheet form which is then applied to re-inforced bubble film creating the air gap. We then produce the foil in various rolls, retail packs or even jumbo rolls for localised manufacturers to re-work.

Single Foil works on the priniciple of improving the general energy performance rating in properties .

Double Foil also achieves this with the added bonus of reflecting heat during summer months or indeed in warmer climates.

Radiator Foil pushes heat back into the building as opposed to being absorbed into the walls, reducing fuel bills in the process.

Applications for Yuzet® Foil insulation

  • Improving energy consumption performance
  • Helps provide a thermal break which reduces the risk of thermal bridging
  • Wall insulation
  • Under floor insulation
  • Insulating out buildings such as garages, sheds & greenhouses.

Why should I use Yuzet® Foils

  • Can be used in most types of roofing structures
  • Can be cut easily with a knife
  • Lightweight during installation
  • Attached with staples
  • Effective with a 30mm air gap
  • Can be laid horizontally or vertically with same results
  • Highly reflective
  • Helps with U & R values

U and R Values

Thermal performance of Yuzet® Insulation Foil is excellent and in line with all conventional norms for insulating material.

The R-value measures a material’s resistance to conductive heat flow, i.e. how quickly heat will pass through it. The higher the R-value, the higher the thermal resistance, which means that the insulation properties are better.

The U-value is the most accurate way of measuring a material’s insulation ability, as it considers not only thermal resistance but also other factors contributing to heat loss such as differences in external and internal temperature, etc. As a general rule it can be said that the lower the U-value, the better the insulation properties.
