What does R-value in insulation mean?
Effectiveness in insulation is measured by R-value, resistance to thermal transfer. The higher the R-value, the better job the insulation does at blocking warm and cool air from moving where you don‘t want it. Building codes often specify which R-value is needed in each part of the structure.
Real-life v. the lab
R-values are determined in specialized labs. However, in reality, a higher R-value doesn’t mean that the product is more effective in real life. For example, traditional fiberglass batting with an R-Value of R-19 will usually perform at less than 50% of that rating. That’s because the batting will slip in some spots, get compressed in others, and inevitably have some gaps. Since spray foam seals the building completely and holds its form, an R-value of R-13, for example, will always be R-13.
There’s more to insulation than meets the eye
You may never actually see it, but you’ll always know if it’s there. Insulation creates pockets of air, which block air from moving in or out of the structure. A well-insulated building is more comfortable and cost-effective to maintain. But you knew that. What you may be wondering about is how to know what type of insulation is right for you.
HERE'S A SYNOPSIS OF SOME OF THE MORE COMMONLY USED APPLICATIONS
Of course, there’s nothing like real-live guidance, and we look forward to providing you with that when you’re ready.
1. Open Cell Foam
Spray polyurethane foam, commonly known as spray foam, is an insulating foam plastic that is spray-applied as a liquid and then expands to many times its size to fill and seal the cavity it‘s applied to:
- Semi-rigid and soft to the touch
- Creates phenomenal air seal, eliminates drafts
- Provides excellent soundproofing
- Less dense than closed cell foam
2. Closed Cell Foam
Features high density and is harder to the touch
- Highest R-value per inch
- Provides structural strength
- Increases racking strength in structure
- Used in crawl spaces and areas with high moisture content in the air
- FEMA approved for flood zones
- Acts as an air barrier
- Qualifies as a moisture barrier
- Qualifies as a vapor retarder
3. Thermal Barrier
Fire protective barrier applied on top of foam in specific applications.
- Often applied as an intumescent coating
- Approved applicator of the ONE STEP THERMAL BARRIER FOAM
- Spray Fireproofing
4. Sound Insulation
Used to create quiet zones or between tenants
- Applications include open-cell foam, blown cellulose, and Roxul soundproofing bat insulation
