Reflective insulation is, as a rule, a two-layer material of small thickness, which includes the main insulation and a reflective surface. Typically, the latter is foil, for which the corresponding coefficient can exceed 90%. In the role of the base, different materials are used with high efficiency. In order to give the layers good physical and mechanical properties, manufacturers use mesh as one of the layers.
Where different types of foil insulation are used: BestIzol
If you are interested in reflective insulation, then you can consider several varieties of such materials, among others, BestIzol should be highlighted, which is a vapor, heat and sound insulation with a high level of reflectivity.
This insulation consists of closed-cell polyethylene film and aluminized foil. Polyethylene foam is used with a thickness that depends on its brand and varies from 2 to10 mm. As for aluminum foil, its thickness can reach 14 microns, while the minimum value is 7.
Today, this reflective insulation is offered for sale in several varieties, among others, type “A”, type “B” and type “C” should be distinguished. The first option is insulation based on polyethylene foam with one-sided foiling. The second solution has a double-sided foil, while the third has a layer of foil on one side, and on the other, an adhesive with a release material is applied to the surface.
This insulation is effective not only for residential buildings, but also for the insulation of ships, vans, refrigerators, metal structures and ventilation ducts. This material is very light and strong, so it can be embedded in metal structures and fixed to control elements or a frame. This eliminates additional costs for temporary structures and insulation grids.
Additional area of use of "BestIzola"
The above-described reflective insulation has a fairly wide range of uses. It can be applied by installing behind heating radiators, which allows you to increase their efficiency by 30% maximum. If you install such a sheet behind a heating radiator, then more heat will be reflected inside the room. The radiation will work to heat the room.
Using the "BestIzol" type "A", you can insulate pipes of small diameter. The material wraps around the products, but forhot pipeline, in order to achieve maximum effect, it is necessary to use 20 mm banding rings from the same material. An alternative solution is an asbestos cord or fluoroplastic. In this case, the effect of a thermos is formed between the insulation and pipes. However, in this case it is recommended to purchase "BestIzol" type "B".
How to use BestIzol
The above-described reflective insulation, the use of which is almost unlimited, is also used for roof purlins. To do this, the material is laid from cornice to cornice, and it is necessary to pass it through the ridge. It can sag 20mm between runs. Fastening is carried out by building brackets, which are installed at a distance of 150 mm from each other. At the same time, ventilation is maintained, which is provided for by the design of the building. Double-sided insulation is suitable for this.
If it is used to insulate attic spaces, then it will be necessary to ensure that there is an air gap between the insulation or and the ceiling. To do this, purchase reflective insulation with one-sided foil, which should be directed outward. Additionally, slats are laid, the distance between which will be 250 mm.
Where to use "Penofol"
Traditional insulation can be supplemented with Penofol. It forms the basis of the design during the construction of low-rise frame buildings, increasing the thermal resistance of the walls, because their volume increases. Using thisinsulation, you can reduce heat loss as it is highly reflective and a reliable vapor barrier.
Reflective insulation "Penofol" complements the massive insulation and allows you to reduce its volume, increasing the service life. You can use the material for insulation:
- lofts;
- roofs;
- mansard.
It goes to insulating floors and their insulation, as well as insulating walls, ventilation ducts and pipes.
How to use "Penofol" for the roof
The maximum effect when using "Penofol" for the roof can be achieved by providing an air space of 2 cm on both sides of the insulation. Aluminum is an excellent conductor of electricity, so wiring should be protected. Before installing the material, it is important to take care of the reliability of the electrical wiring. The insulation used will reflect up to 97% of the heat flow. The inner layer of the roof insulation must be sealed.
The reflective layer should be directed towards the heat source. In order to achieve complete tightness and waterproofing, the joints must be glued with foil tape. The basic rule is that foil acts as an excellent conductor of electrical current. To fix the material from the inside, prepare screws or a stapler. For this, it is most convenient to purchase 5 mm sheets. If you have to work in a house or apartment, then you need to use one-sided material. But in the case when the walls are very cold, it shouldcarry out additional insulation with polystyrene foam or cotton wool.
Purpose of VPE lavsan insulation
EPE reflective insulation is made of polyethylene foam and has a silver surface. This material is practical, ready to serve for a long time, affordable and versatile. It is used for noise and heat insulation of premises for various purposes. With it, you can achieve partial damping of vibration. Products are placed under the decorative coating of the floor, ceiling and walls, and they can be used even in conditions where high humidity will remain during operation.
How to use HPE insulation
Reflective insulation Lavsan VPE can be mounted on surfaces with any configuration. The material is effective in low-rise construction, and the canvases are fastened end-to-end, while overlapping must be excluded. The joints must be sealed with a special foil tape with an adhesive layer. You can use a composite of polyethylene and aluminum for this.
The connecting element is characterized by strength, as well as moisture resistance and the ability to reflect infrared radiation and ultraviolet. The service life can reach the time of using the foil layer itself. By using VPE lavsan reflective insulation, you can reduce heating costs and achieve significant energy savings.
You can lay insulation under parquet, laminate or other floor coverings, as well as in a warm floor system underplaster or cement screed. Reflective insulation 10 mm is the thickest version of this coating. The minimum thickness is 2 mm, while the width remains the same and equal to 1 m. But the length varies from 10 to 100 m. For a 10 mm thickness, the price of one square meter will be 58.13 rubles.
How and where different types of reflective insulation are used
All varieties of heat-reflecting insulation can be classified into three types, each of which is designated by its own letter. For example, Type "A" is a polyethylene foam material with foil on one side. This insulation is universal and can be installed on any surface. It is glued with special glue or nailed to a wooden surface with staples or nails.
Single-sided coating speaks for itself, because this solution can be used in most cases for interior work, installing foil inside the room. Type "B" is also foamed polyethylene, but its thickness reaches 5 mm. The coating here is on both sides, it is foiled and expands the area of use. This material can be used for refrigerating chambers, which should not allow heat to pass through on the one hand, and on the other - not to release cold. This reflective insulation can be used for walls if you need to maintain your temperature in different rooms.
The last kind of such insulation is Type "C". If we compare it with type "A", then it has a self-adhesive base, but otherwise it is almost the same. As an added benefit,ease of use.
Conclusion
Today, there are other types of thermal insulation. Among others, one should single out those in which the same foil is used as a reflector, and bas alt wool acts as the main layer. It can be one-sided or two-sided, so this insulation is an excellent solution for frame buildings. This is true for other buildings also because the material has a minimum thickness, which allows you to save free usable space inside the house, and this can be important when it comes to typical apartments in multi-storey buildings.
