Thermal insulation foam - an excellent result in the shortest possible time

Thermal insulation foam, distant "cousin" foam

As is known, always involves cheap and not very high quality, the exception to this rule is negligible.For example, the insulation of a wooden house foam - insulation is obtained relatively good and "penny", but fears the fire insulation in combination with the tree gives the doubled risk of fire when the slightest.However, and quite expensive mineral wool, as it turned out, it may be harmful to health if made with deviation from the standards.Therefore foam insulation polyurethane foam (PUF or short) opens completely different horizons for those who are looking for optimum thermal insulation.Needless to say, covering 500 square meters per day - a total area of ​​almost all the internal surfaces of a country house.

Thermal insulation foam, in a frozen state reminiscent of the foam, is very simple, but first you need to dress in a tight protective suit - scrub insulation will be difficult even with a weak acid.Once prepared and wearing equipment starts spraying process itself, because the foam is a ready-made mixture.By the way, to perform the polyurethane foam insulation you are unlikely to succeed, because in general it is difficult to find for sale, most of the market services are provided by spraying polyurethane foam.But if the heater turned in your hands, feel free to take a special gun and direct the jet composition of the prepared surface.

polyurethane foam hitting the insulated surface begins to harden very quickly, at the same time gaining volume.It is at this point increases the viscosity, and thermal insulation, as well as its adhesion to the surface.

fill in the gaps between the roof rafters and specially stuffed the walls with vertical bars, you can quickly warm your home without any seams and joints.Given that polyurethane foam is moisture and is an excellent vapor barrier , and are not afraid of the wind and can withstand heat up to 80 degrees without any damage, for insulation of walls and ceiling, you can do without additional insulation layers, a lot of this saving.In other words, proper insulation of the house justifies payment of polyurethane insulation.

Thermal insulation with foam - an unexpected way to use

In the process of construction of a building or simply by replacing old window frames on the windows workers often used foam to fill its space around the window frames.Such an action is performed due to the fact that this material is an excellent thermal insulation, among other things tight, and provides excellent protection against drafts and damp street.And why not go ahead and do with foam insulation, for example, the entire space of the walls and the floor?And at the same time grab the ceiling?Slightly different scale, the technology is the same, the more it is, in fact, the same polyurethane foam, which is described above, is used for domestic use as a sealant.

What is most appealing about the mounting foam - leaving volumes. completely devastated a small, seemingly, the capacity, you will get 40 to 50 liters of foam mass , which, being uniformly distributed on the surface, cover considerable space even when the layer thickness of more than 10 centimeters.Use foam for insulation of the floor in a wooden house is quite justified, because it has such a high strength after curing, that it is possible to go even in the absence of the deck.Just fill in the space between the joists foam and now you have finished monolithic insulation, not afraid of no water, no mechanical damage.Same thing with a loft - Gulf gaps with foam between the rafters, you can immediately close the resulting insulating layer any decorative panels.

to be aware of polyurethane foam as a whole and in particular the mounting foam

course, the polyurethane foam is not a panacea for plugging absolutely any gaps in your house to turn it into invulnerable to various natural factors fortress.For example, the polyurethane is able to withstand relatively high temperature, but within certain limits, up to approximately 80 degrees, the possibility of ignition on a heater, and if it is made of poor quality, to be expected in combustion emissions of harmful substances.Also, polyurethane, produced by technologies doubtful (unknown manufacturer) may eventually begin to disintegrate into its component even from constant exposure to water vapor.Hence the conclusion - choose only quality materials from trusted manufacturers.

Polyurethane foam, polyurethane and being more heat-resistant and can withstand even direct contact with fire.However, she also has a couple of drawbacks to be considered when creating a thermal insulation.Firstly, the foam core can not fill the closed space, because the composition can not pass in the foamed state, remaining essentially without access of air with a certain humidity level source liquid polyurethane.One more thing to consider - polyurethane foam in all its forms can not withstand prolonged exposure to direct ultraviolet rays, that is, sunbathing mounting foam contraindicated.By following all the measures to iron out the shortcomings of the material, we can confidently expect not his long service.
