How And Where To Use Rigid Foam Insulation

The rigid foam board insulation comes in three types, namely: polystyrene, polyisocyanurate and polyurethane. Each comes with its own specific properties which make them each suitable for specific applications. Here are uses of the different types and also the precautions you should be taking while using those.

First of all let?s take polystyrene. This kind of insulation requires profound heat and pressure to cast into shape. It is the ideal material for insulation of walls and installing in the attic. Though more costly than the other two kinds, it?s characteristically a lot stronger and durable than the other two.

Boston rigid foam insulationBead board is the second type of rigid foam insulation. It is produced in such a manner that bead expands to fit the space, giving a better insulated area. This type of insulation is generally used in day to day common products. Because of the bead spacing moisture gets absorbed.

The third type of insulation comprises of polyisocyanurate and polyiso foam boards. This is a very tough and durable material that can withstand extreme temperatures, making it ideal for installing attic insulation. It provides a fantastic moisture barrier when applied in conjunction with aluminum foil facing.

However, there are a couple of points you should be aware of before venturing into handling of rigid foam insulation. We?ll start with the flame retarder. This item takes a lot to set fire to but once it does, it burns steady. It also smolders for a while. Safety regulations necessitate your using flame resistant material like dry wall, panel, or gypsum wall board above the insulation.

Direct sunlight causes it to deteriorate. So, when installing attic insulation it needs to be protected by using acrylic silicone, roofing felt, rubberized paint asphalt, or tar. This kind of insulation is a favorite of bugs that make nests therein. So, while insulating basement or floors you?ll be better off by using insecticide treated insulation. Also, keeping the insulation in the interior discourages bugs. Rigid foam insulation absorbs water vapors from the atmosphere and retains moisture.

The above could simply lead to mold formation and damage wood. To overcome this problem you need to employ a vapor diffusion retarder, particularly when installing attic insulation. From the given three kinds of insulation i.e. loose fill, batt and blanket, and rigid foam board insulation, this involves minimum initial cost. Though it?s found useful for many kinds of applications, this item could be counter productive if not installed the right manner or on ignoring the safety precautions. It?s imperative that you carefully read safety precautions and check the local building code regulations before getting started with installation of this material.
