Polyisocyanurate insulation is more or less a refined version of the very common material polyurethane. The primary purpose of any insulation is to provide protection against heat from the outside atmosphere such as direct sunlight. It also to provide protection against live wires in buildings and against the high amount of heat that is discharged from these wires.
Polyisocyanurate roof insulation is perhaps the most technologically advanced thermal insulation that is available in the market today for garage door insulation. As mentioned earlier, it is far more superior to the now outdated polyurethane because of the favorable strength to weight ratio and rigidity that it offers any insulation installation.
Such Styrofoam insulation is usually manufactured from a foam based spray and afterwards, panels which are comprised of the aforementioned foam are laminated with sheets of aluminum and then go on to be used in many varied applications everything from insulation in industrial scale air-conditioning vents to heating and cooling.
Sometimes such vents can be pre-fabricated with the polyisocyanurate insulation already in place, to save it being installed at a later time. These are otherwise known as sandwich panels. Such insulation can also be found in industrial and commercial piping systems, but one particular thing called shrinkage must also be accounted for before everything is put in place.
Individual panels will decrease in size over time and even though manufacturing criteria stipulates that the shrinkage must be kept to within 1% of the original size, the decrease in size can mean that the effectiveness of the insulation decreases slightly. The effect of shrinking panels can be worsened still if the setup has some sort of water vapor barrier to prevent moisture build up.
All in all though, a good insulation system will save energy in the long run and provide a sound way to reduce reliance on fossil fuels and lessen the impact of global warming by keeping desired thermostat inside the house longer. A polyisocyanurate insulation installation will comply with and even exceed the expectancies all of the relevant regulations set down by such institutions as the US government and the Environmental Protection Agency.
One important eco-friendly application of polyisocyanurate insulation on spray foam insulation kits is the point that it diverts waste that would usually go to landfill back into the manufacturing process. With how to dispose of common waste becoming more and more of a problem as the population increases and landfills overflow, the allocation of reusable materials that otherwise would have been thrown away is an important factor to consider.
Some polyisocyanurate insulation is even made from 100% recycled material which means that in the case of a building renovation, old insulation can be torn down and specifically reused to create the new insulation. This greatly reduces the carbon footprint of some 880 million pounds of insulation which is currently being used in the construction of the buildings of today. Use polyisocyanurate insulation for a more modern and efficient thermal insulation in any kind of insulation installation.
