Expanded Polystyrene Foam Board Insulation Waterproof

It performs well as insulation for garages pole barns basements and crawl spaces.

Expanded polystyrene foam board insulation waterproof.

Kingspan insulation r 3 common. 0 56 in x 4 ft x 8 ft. Poly shield s closed cell eps core wraps the structure in permanent r value retarding radiant heat flow and reducing air infiltration. Our photo above left shows polystyrene foam insulating board below a concrete slab being poured in two harbors mn.

Poly shield is made of cellofoam expanded polystyrene eps rigid insulation faced with a tough poly laminate or a reflective foil facer. Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation. Polystyrene insulation is very rigid unlike its fluffier cousins. Types of insulating boards choose from three types of insulating foam core boards for wall insulation.

Unlike other insulation materials it is waterproof and lasts a long time. 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. Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical. As an insulator it can withstand extremes in temperature and is also a noise reducer.

Each type comes with unique advantages. 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. 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. Expanded polystyrene or xps extruded polystyrene or eps and polyisocyanurate or polyiso are the three main types of rigid closed cell insulation materials.

Poly shield offers both high efficiency and low cost insulation. It has a higher r value per inch of thickness it s resistant to moisture and is easy to work with. 1 in x 4 ft x 8 ft. Widely reported research by dow chemical co.

Foam board insulation is a great alternative to the very common fiberglass batt insulation that is in most of our homes. There are a few different kinds of foam board insulation diyers should know about. Shows that their extruded polystyrene foam insulation on average outperforms expanded polystyrene eps in below grade insulation applications.
