New, multi-layer insulating structures appeared on the market a few years ago. For the same thickness, they offer better insulation performance than, for example, traditional polystyrene-based products. These structures comprise a number of layers of different materials, including metallized film layers with infrared reflective properties.

These applications use a number of different types of film, particularly PET and PE film, which can be metallized on one side or both, if needed.

A commonly used structure is expanded polystyrene structure laminated with metallized polyester film, which improves the product's insulation performance.

Non-woven, largely polyethylene fiber based-films are also metallized and incorporated into structures used in the construction industry, introducing humidity barrier properties and strengthening the insulation performance of the structure by reflecting infrared radiation.

The following is a non-exhaustive list of the films that we offer which are commonly used in insulation:

* Plain or corona-treated 8µm to 12µm PET, metallized on one side or both to standard optical density

* 35µm LDPE metallized to standard optical density

Metallization is used in the solar textiles market for its reflective properties. The use of metallized window shades to reflect light considerably reduces the amount of heat that is transmitted into a building through the windows on sunny days. The films help to control the temperature inside the building, limiting the use of air-conditioning and resulting in considerable energy savings. These shades can be fitted inside and out, with those fitted outside having the greatest effect.

One or both sides of the product can be metallized.

With a wealth of experience in this business sector, Met-Lux is an indispensable partner for all your PET, glass fibre/PVC or OPP-based textile metallization projects.
