Expanded Polystyrene Foam Board Insulation Waterproof

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.

Expanded polystyrene foam board insulation waterproof.

Polystyrene insulation is very rigid unlike its fluffier cousins. 0 56 in x 4 ft x 8 ft 1 unfaced polystyrene foam board insulation item 511270 model 100000050497. Widely reported research by dow chemical co. Kingspan insulation r 3 common.

It has a higher r value per inch of thickness it s resistant to moisture and is easy to work with. Shows that their extruded polystyrene foam insulation on average outperforms expanded polystyrene eps in below grade insulation applications.

Our photo above left shows polystyrene foam insulating board below a concrete slab being poured in two harbors mn.

1 in x 4 ft x 8 ft. Each type comes with unique advantages. Poly shield is made of cellofoam expanded polystyrene eps rigid insulation faced with a tough poly laminate or a reflective foil facer. Unlike other insulation materials it is waterproof and lasts a long time.

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 s closed cell eps core wraps the structure in permanent r value retarding radiant heat flow and reducing air infiltration. What is foam board insulation.

0 56 in x 4 ft x 8 ft. As an insulator it can withstand extremes in temperature and is also a noise reducer. Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation. Foam board insulation is a great alternative to the very common fiberglass batt insulation that is in most of our homes.

It performs well as insulation for garages pole barns basements and crawl spaces. Poly shield offers both high efficiency and low cost insulation. Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical.
