Foil insulation - this is relativelya new heat insulating composite material that is coated on one or both sides with a layer of polished foil with an aluminum layer 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:
- Insulation of heat pipes.
- Warming of pipes in engineering networks of a building of hot and cold water supply.
- Thermal insulation of air ducts, ventilation ducts.
- Technical insulation of process equipment.
- Thermal insulation of walls and floors in residential and public areas.
- 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 -expanded polyethylene. As a rule, this is the most effective heat insulator. This multilayer material is sold in the form of thin rolls of material covered 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 for the insulation of 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 damping properties, resistance to biological pests and chemical influences.
- Folgated material, the basis of which -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.
- Foamed polystyrene foam or insulation withfoil, the name of which is isolone or foil. Used for warming the system of warm water floor and heating. Such insulation with foil refers to a strong heat-insulating material that retains its properties at a temperature of -180 ° C - + 180 ° C.
- Basalt heat insulation insulation withfoil. 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 temperatures 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.
- Environmentally friendly material that does not emit any toxic and hazardous substances.
- Installation is quite simple and fast. Even a layman can properly perform the installation, for which it will only be enough to use a very simple instruction.
- It has excellent soundproof characteristics.
Insulation for bath with foil is good becauseexcept 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 disadvantage of this insulation is that the foil is susceptible to corrosion.

Mounting foil insulation
The material is set up with a reflective sideinside the room. This allows you to reflect and keep the heat. Mounted insulation butt-end, and not overlap, which significantly reduces construction costs. For fixing use a construction stapler or nails of small size.
Between finishing and insulation materialA gap of approximately 12-25 mm is left, which contributes to additional thermal 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 commensuratewith the cost of alternative competitors having similar heat-insulating 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.
