The difference between FOAMULAR® 150 vs 250
FOAMULAR® is a popular energy saving, moisture resistant, XPS insulation from Owens Corning
. The difference between 150 and 250 is simply the compressive strength
of each type.
FOAMULAR® 150 has a compressive minimum PSI of 15
FOAMULAR® 250 has a compressive minimum PSI of 25
FOAMULAR® 400 has a compressive minimum PSI of 40
FOAMULAR® 600 has a compressive minimum PSI of 60
FOAMULAR® 1000 has a compressive minimum PSI of 100
Primary Uses of FOAMULAR® XPS Insulation
Establishing the Right Foundation
On foundations, moisture-resistant FOAMULAR® insulation insulates while at the same time its durability protects waterproofing membranes from backlling damage, putting one more obstacle in water’s path (soil to foundation).
Going Under Slab
For use under slabs, in a variety of compressive strengths suitable for the lightest residential to the heaviest industrial floor loads, FOAMULAR® insulation is durable enough to be walked on while placing slab reinforcing and concrete.
Insulating Below Grade
In below-grade applications, FOAMULAR® insulation’s high resistance to water absorption makes it the only choice to protect against constant and relentless moisture threats present throughout a building’s lifecycle.
Sheathing and Masonry Wall
FOAMULAR® sheathing and masonry wall insulation products are highly water resistant for cavity applications. They maintain their R-value over the life of the building and provide a “continuous insulation” layer prescribed by ASHRAE 90.1
Benefits of FOAMULAR® XPS Insulation
The R-Value of FOAMULAR®
Insulation’s R-value is based on real-time aging and the product is warranted to maintain 90 percent of its insulating value for 20 years. FOAMULAR® insulation has a combination of characteristics that yield very low water absorption and is available in a range of compressive strengths that accept loads up to their design limit with little deformation.
Moisture Protection of FOAMULAR®
Water — an ever present element in building construction — gets in by design in applications like rain screen
systems, or as a result of natural aging, design or construction aws. Almost all construction applications, at some time, must resist water in the form of a liquid, a vapor or solid ice.
Not all insulations, however, provide adequate water resistance necessary to meet real world construction
applications. Insulation that absorbs water loses R-value and other important physical properties resulting in costly customer complaints, call-backs and damaged reputations.
