Expanded Polystyrene Foam Board Insulation Waterproof

It has a higher r value per inch of thickness it s resistant to moisture and is easy to work with.

Expanded polystyrene foam board insulation waterproof.

Shows that their extruded polystyrene foam insulation on average outperforms expanded polystyrene eps in below grade insulation applications. Expanded polystyrene or xps extruded polystyrene or eps and polyisocyanurate or polyiso are the three main types of rigid closed cell insulation materials. Compare click to add item r 3 expanded polystyrene foam board insulation 3 4 x 14 1 2 x 48 6 pk to the compare list. Widely reported research by dow chemical co.

Types of insulating boards choose from three types of insulating foam core boards for wall insulation. 0 56 in x 4 ft x 8 ft 1 unfaced polystyrene foam board insulation item 511270 model 100000050497. Polystyrene insulation is very rigid unlike its fluffier cousins. Poly shield s closed cell eps core wraps the structure in permanent r value retarding radiant heat flow and reducing air infiltration.

Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation. Poly shield offers both high efficiency and low cost insulation.

Unlike other insulation materials it is waterproof and lasts a long time. Kingspan insulation r 3 common. 1 in x 4 ft x 8 ft. It performs well as insulation for garages pole barns basements and crawl spaces.

0 56 in x 4 ft x 8 ft. Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical. Poly shield is made of cellofoam expanded polystyrene eps rigid insulation faced with a tough poly laminate or a reflective foil facer. Our photo above left shows polystyrene foam insulating board below a concrete slab being poured in two harbors mn.

There are a few different kinds of foam board insulation diyers should know about. Expanded polystyrene also referred to as eps white board and bead board has the lowest r value of the three rigid foam board insulation types but is the most economical and versatile it can be used anywhere insulation is needed. As an insulator it can withstand extremes in temperature and is also a noise reducer.
