Product Overview

Choosing The Right Insulation

Faced Insulation

Faced

Face insulation uses kraft paper vapor barrier to control moisture transmission between 
walls and floors 

*Check your local building code for requirements
Unfaced Insulation

Unfaced

Unfaced insulation does not have a vapor barrier; used over existing insulation in the attic, or where moisture control is not needed

Rolls Insulation

Rolls

Continuous rolls are easy to transport and can be cut to length; great for large areas

Batts Insulation

Batts

Come in pre-cut lengths for faster installation and each package contains more square feet than rolls; ideal for framed cavities

Blow-In Insulation

Blow-In Insulation

Installed using blowing machines, best for adding additional insulation in attic

Regional R-Values

regular insulation is rated R-30-60, how does this relate for insulation? Am using to insulate a ceiling on a flat roof home.

Asked by: Lina
For roofing application, use Thermapink, extruded XPS (similar to Foamular)...comes in 1", 1½", 2", 3", 4" thicknesses, R5 per inch. Can use multiple layers to achieve desired R value.

IS THE FOAM SANDABALE?

I WANT TO PLACE A SHEET IN MY SURFBOARD AND I WANT TO SAND IT DOWN TO SHAPE. XPS IS USED IN MOST SURFBOARDS THESE DAYS.
Asked by: 5121200
Yes absolutely sandable, unlike bead foam it does not break up when sanded. I creat stage props all the time from this but you must must must wear a good mask. There will be a fine dust you don't want to breath. I cut with a jig saw, or Lind blade box knife then sand by hand with a fine sand paper. Orbital sander also works but you need a light hand. You can easily and lightly sand of text for painting and for durability I coast with a flexible coating such as flex coat or sculptor coat about $50 a gallon available at local theater supply stores or online at Rosebrand. It paints beautifully with acrylic or latex paints. Spray paint will melt uncoated foam.

The bathroom gets very cold in the winter. I wanted to put insulation under the shower floor area an along the 2x6' sides and end. I pressed the 2" insulation up so that it contacted the floor. I have seen a 100% improvement in the temperature in the bathroom. The product met my expectations and was easy to trim to size with a drywall saw

I had a HomeOwner's Assoc. request a new sign to replace an old, weathered redwood sand-blasted sign. I suggested bonding two pieces of an 1/8" Aluminum substrate to either side of a sheet of Foamular 150 to make the new sign. They agreed, and I was able to cut the foam to shape with an electric carving knife easily. I used 100% Silicone for bonding, and a dark brown paintable silicone around the outer edge, clamping it together until cured. All the faux-painting of wood grain, shadows and letters were done in Acrylic House Paints.

Rated 5 out of 5 by from Awesome medium for stage props I love using these insulation foam boards for stage displays. They are light to transport but very sturdy. They withstand tons of handling. Using water-based exterior paint, they last through many seasons outdoors.

Rated 5 out of 5 by from Fantastic results... I had two objectives... 1. Insulation 2. reduce noise for neighbors. I accomplished both. I used this 2" foam insulation in my 12 x 16 shop walls and ceiling. I then sealed any gaps with Great Stuff foam spray. The shop is now tight and can be heated with only a small ceramic 1500 watt heater. It's 28degress outside and I am able to be content in my shop. These panels were easy to score and snap to the appropriate size. Would highly recommend!

Rated 5 out of 5 by from Great product for DIY archery targets... Odd, I know, but get one 8'x4' sheet of this and cut it into 24"x16" sections at 2" thick, stack them into a wooden frame and compress with either ratchet straps or some sort of threaded rod on either side. Makes for an excellent 24"x24" faced target capable of handling broadheads for less than half the price of an 18"x18" Block classic target. Even better, when a section starts chunking, just loosen the compression and move a layer up or down. DIY archery target, works a treat, light weight, lasts a while and saves a fair amount of money. Mine has lasted 3 years of minor to moderate broadhead and field point use from a 50lb recurve before needing to have the layers rotated, totally serious.
