Spray foam is fast becoming a phrase that keeps popping up in conversations. Spray foam roofs were some of the first applications for spray polyurethane. The most popular growing applications today for spray foam insulation are walls, foundations, attics, joists and crawl spaces. It’s amazing how many people are getting the blower door test and other types of energy efficiency tests on their homes only to have trouble locating a company that has certification, experience, knowledge and equipment to apply spray polyurethane foam (SPF).
Some Industrial Applications for Spray Foam Insulation and Roofing:
- Winery tanks
- Water tanks and towers
- Grain storage tanks
- Poultry houses
- Freezers and cold storage facilities operating at -40 below zero
- Encapsulating old chimney stacks
- 55 foot dome on a Department of Transportation road salt shed
- Re-purposed shipping containers can become 2 story modular homes with the help of spray foam insulation
- Waste digester tanks
Closed-Cell Spray Foam Insulation Benefits (residential or commercial):
- Provides stability, close-cell spray foam insulation prevents shrinkage and settling in your building.
- Reduces energy use by lowering heating costs
- High R values- on 3 inch thickness R value is R19 or higher and 6 inches of closed-cell insulation is about R38.
- Spray foam is an excellent sound deadener and lessens sound transfer between walls
- Less labor cost to apply spray foam than asphalt shingles or other types of roofing material.
- Fire retardant
- Air barrier blocks air infiltration
- Vapor barrier helps prevent moisture
No matter if you are looking to use spray foam on your roof or in your interior for insulation it is important to include all costs involved when estimating payback. When comparing spray foam to fiberglass insulation it’s good to keep in mind that fiberglass does not fill up the cavities where the air is coming from – it just puts a blanket over the hole. Here are some other points to remember:
- Fiberglass insulation also does not seal out condensation or water infiltration, so if you are not properly sealed then water damage can occur under your insulation. This can lead to all kinds of unforeseen costs down the road.
- Remember the high cost of heating and cooling bills will be dramatically reduced by approximately 40% – 50% or more – make sure you factor this in when calculating your payback.
- Operating wear and tear on your HVAC systems will be lessened, increasing the system’s life span.
- Spray foam prevents mold and mold spore growth by preventing condensation and water infiltration.
- SPF keeps dust and pollen out by eliminating air transference. This increases indoor air quality and leads to less allergies and lost days from work.
- Buildings with electrical equipment, product warehouses and computers should consider what a little water or condensation would cost them if it should ruin a computer system or a warehouse of expensive stock.
So if you are looking at insulation in a new addition, an unfinished attic or you’re tearing down walls of a room check out spray foam insulation for your next project you’ll be glad you did.
