Insulation with foil: types and applications

A foil insulation is a relatively new heat insulating composite material that is coated on one or both sides with a layer of polished foil with an aluminum interlayer or a metallized polypropylene film. Due to the aluminum component of the coating, this product is able to reflect and store heat in the room, and the reflection effect reaches up to 97%.

Insulation with foil: application

Its scope is quite diverse. A heater with foil is used for:

1. Insulation of pipes of thermal networks.
2. Warming of pipes in engineering networks of a building of hot and cold water supply.
3. Thermal insulation of air ducts, ventilation ducts.
4. Technical insulation of process equipment.
5. Thermal insulation of walls and floors in residential and public areas.
6. Soundproofing of interstrate coating.

Varieties of foil insulation

A heater with foil is currently produced in four main types, which differ not only in appearance, functional features, but also in the field of application.

• Foil insulation, the basis of which - foamed polyethylene. As a rule, this is the most effective heat insulator. This multilayer material is sold in the form of thin rolls of material coated with an aluminum layer. This insulation with foil (the name is another - penofol) can have an adhesive layer in order to provide convenience and reliability of fastening to the surface. Basically it is used to insulate the floor, roof, walls, ventilation system. In addition, this material is quite effective for insulating pipes, ducts. It has good elasticity, steam and waterproofing, thermal protection and soundproofing, high cushioning properties, resistance to biological pests and chemical influences.
• Foiled material, the basis of which is mineral wool. This unique insulation with foil is available in the form of rolls (mats), plates and cylinders. Its basis is mineral wool. This environmentally friendly, durable and non-flammable material is used for all types of insulation. Perfect for insulation of sauna, warming baths, roofs, chimneys.
• Foiled polystyrene foam or insulation with foil, whose name is isolon or foil. Used for warming the system of warm water floor and heating. Such a heater with foil refers to a strong thermal insulation material that retains its properties at a temperature of -180 ° C - + 180 ° C.
• Basalt heat-insulated insulation with foil. It is used in various branches of heat power engineering, in housing construction, industry, in aircraft building, and also for erection of filling stations. This material is non-flammable and able to withstand a temperature of -200˚C + 700˚C. It has a higher resistance to aggressive environmental influences.

General characteristics of foil insulation

• The material is stable at a large temperature range.
• Does not absorb moisture and has good resistance to reflection.
• It has high heat, steam and waterproof performance.
• Ecologically clean material that does not emit any toxic and dangerous substances.
• Installation is quite simple and fast. Even a layman can properly perform the installation, for which it will suffice only to use a very simple instruction.
• It has excellent soundproof characteristics.

Insulation for a bath with foil is good in that, in addition to insulation can still serve as an additional reflector of thermal energy. This material is most popular and popular in the construction of steam rooms and washrooms.

The main and biggest drawback of this insulation is that the foil is susceptible to corrosion.

Mounting of foil insulation

The material is set up with a reflecting side inside the room. This allows you to reflect and keep the heat. Mounted insulation butt-end, and not overlap, which significantly reduces costs during construction. For fixing use a construction stapler or nails of small size.

Between the finish and the thermal insulation material a gap of approximately 12-25 mm is left, which contributes to additional heat protection. Visible joints are glued together with a special aluminum (foil) tape. Installation work is completed.

How to choose a foil insulation

The price of any foil insulation is commensurate with the cost of alternative competitors that have similar thermal insulation characteristics. However, with the help of a heater with foil, it is possible to save on factors such as installation time and space (a heater with a foil thinner than usual), and also to receive environmentally friendly and fireproof material that is used for thermal insulation of absolutely any objects. To stop the choice at purchase follows on a heater which is covered with an aluminum foil, instead of by a spraying as he, most likely, will not work.
