It relates to an insulating foam board insulation on the market different foam with a rigid form. These panels are typically type, and to the production of chemicals. Three common types of foam board insulation material is poly isocyanurate and polyurethane, expanded polystyrene foam (EPS) and extruded polystyrene foam (XPS).

Poly-isocyanurate and polyurethane foam board insulation materials are the most expensive type. But, in terms of thermal insulation, this category is also considered to be the most effective. Also known as Polyiso, it has a newer building on a global scale infrastructure in widespread use. For such, the measured R value per inch of thickness relative to R-7 or R-8. Typically one or both sides with a foil (Al) surface insulation resistance can be further improved, especially in terms of radiation heat. Aluminum foil surface, because the tape will adhere better to the aluminum foil, it is easier to install. Polyiso also to + 2500C over a wide temperature range of -1800C. Are closed-cell foam, contains a low conductivity gas, in some cases, involving CFC (chlorofluorocarbon) and of HCFC (hydrochlorofluorocarbon). During thermal drift, we observed a decrease in the R value, and these gases into the atmosphere destroy the ozone layer. Thus, there is a big disadvantage in the use of such a foam board insulation.

Expanded polystyrene is minimal on the market today use foam board insulation materials, is also the cheapest. Such an R value per inch of thickness R-3.6 to R-4. This is also known mainly for structural insulating panel (SIP) and integrated concrete form (ICF). Thus there have been a variety of finishes, such as vinyl sheets and foil. These finishes can be used as blockers of air and water vapor to protect the interior of the foam. It is commonly used insulation layer roofs and walls of buildings. It does not use CFC, HCFC as a blowing agent and formaldehyde are therefore considered to be environmentally friendly. As an inert, highly stable and non-nutritive material, by way of natural decomposition appears to be impossible. It is also 100% recyclable.
R-value range of extruded polystyrene foam having a thickness of R-4.5 per inch and R-5.0. In these three types of reference, in this kind of cost and efficiency in the intermediate position. Also known as blue or pink color palette plate having a different thickness and edge profile. However, this is more likely to show a consistent density. This limits the water vapor or moisture into the interior of foam structure is excellent. This is the type typically used in basement walls and panels. In the insulation type, which is used in most home construction, mainly because of price and practical.
Although these three common types of price and efficiency as well as their own characteristics may vary, but all of these types are dedicated to providing thermal insulation and improved comfort for each family. All of which provide some support structure based on the density applications. What type of foam board insulation material needs depending on its function must play, but as a foam may be best, the worst effect for many other thermal insulation effect.
