Spray foam insulation is used for many different applications. Spray foam is used in residential, commercial and industrial applications. There are two types of spray foam insulation, closed cell and open cell spray foam. Spray foam in Iowa is the best choice for insulating a home or shop because it adds racking strength and moisture barrier attributes as well as insulating factor. Iowa is considered climate zone 5, so closed cell spray foam would be the best performing insulation. Spray foam insulation performs with superiority using a fraction of the R-value as traditional fiberglass.
The energy savings with spray foam insulation can save up to 50% on energy bills. When we insulate new homes we can get the house to perform super efficient. We have seen less than 1 ACH (air exchange per hour). Building code in Iowa for energy efficient homes require maximum of 4 ACH. There are a few ways to spray foam the attic space. Closed cell foam can be used on the underside of the roof or open cell. The roof line application is good if the HVAC duct work is in the attic. Other methods would be to down spray with closed cell foam onto the dry wall. There are a couple ways to down spray in the attic, one is a hybrid with 2” of closed cell foam with additional fiberglass blown on top of the spray foam. Another method would be to spray 4” plus and go over each rafter to mitigate thermal bridging. Thermal bridging is simply energy transferring through the construction materials. With 2” of closed cell foam 93% of energy is mitigated, with 3” 97% of energy is mitigated. Closed cell applications over 4” has diminishing returns. These are huge energy saving numbers. R-value is a small part of the insulation equation.
In winter months we experience stack effect, where energy is going up and out of the house and the summer is reverse stack effect, where energy is going down and out. Spray foam is approximately 30-40% more efficient than traditional fiberglass, foam also will reduce the required tonnage on the a/c unit and size of the furnace. K-value is a more important number to look at with spray foam. K-value is the measure of thermal conductivity of the materials. U-value measures the R-value of all the construction materials used. A great article to read on these values is, ““R” The Myth of Insulation Values” by David South.
Spray foam in basement and crawl spaces make a huge difference in the colder months. We sprayed a utility room in a basement with no insulation in the rim joist and noticed a difference immediately with unwanted cold air no longer being an issue. We also sprayed a crawl space in Nevada, Iowa and the homeowner noticed an immediate difference in energy and he no longer had a mouse problem. We sprayed an attic space for the same client and he also said there was an immediate difference in the energy savings. One attic we sprayed, we sprayed the underside of the roof with an open cell foam and the temperature difference was less than 10 degrees from the inside of the home in the summer months. Basements and crawl spaces should be sprayed with a closed cell foam only on the concrete walls. Areas with risk of high moisture should only be sprayed with a closed cell spray foam with a moisture barrier attribute.
Closed cell spray foam applied to a roof and walls in a building in Indianola, Iowa. Closed cell spray foam is the superior option in metal buildings with better long term results and performance. We recommend closed cell in metal buildings for longevity and no moisture problems.
Closed cell foam in vaulted and cathedral ceilings in Ankeny Iowa. This proves to be the best insulation option for cathedral and vaulted ceilings hands down. Closed cell foam can mitigate 98% energy loss cold winter months and deflect scorching summer heat.
Closed cell foam in basement walls proves to be the best option on concrete. Closed cell spray foam will not take on moisture or mold if the basement floods. Simply clean and dry the basement. Closed cell spray foam is the only FEMA approved insulation because it does not take on moisture and mold like other insulation systems.
Closed cell spray foam is the best option for work trailers or box trucks. This adds racking strength to the truck or trailer. This also makes conditioning the truck or trailer with heat or air conditioning effortless.
Closed cell spray foam in Ankeny, Iowa. This is a garage application. Heating this garage in the cold winter months will be effortless, and cooling this garage in the summer will also be simple.
Take peace of mind that Precision Insulation and Coatings strives on quality applications. We have been trained in spray foam insulation, concrete leveling and Polyurea coating systems. We are certified and insured giving a peace of mind to the end user that each application is done correctly.
Polyurea is a seamless, elastomeric, fast setting coating that allows for a rapid return to service and eliminates costly down times. This high performance Polyurea is used across a wide variety of applications in residential, commercial and industry. Polyurea is used as a protective coating and lining for a variety of assets, protecting them from water and damaging chemicals. Polyurea is used to line aqueducts and potable water applications, wastewater facilities, secondary chemical containment, spill containment, waterproofing, abrasion resistance, shop floors, industrial floors, parking decks, infrastructure water proofing, heavy equipment protection, and much more.
Precision also offers concrete leveling in central Iowa. We use foam injection methods, providing a long term solution as opposed to the traditional mud jacking methods. The most common reasons concrete settles are water erosion from gutters that are not properly routed, poor soil compaction, frost and heave from winter months, over saturated soil, and rodents burrowing. The most common foam we use in the residential applications would be a foam that can withstand 6500 pounds per square foot compressive strength. We used this foam on a grain bid in the fall of 2018. The floor of the grain bin had settled enough that the augers were breaking. We saved the client thousands of dollars. These geotechnical foams can be used for deep injection to stabilize soils that may have voids, and possibly cause sink holes. Concrete leveling is often used in the oil refineries for the convenience of immediate return to use withstanding millions of pounds of use. Geotechnical foams we use are hydrophobic, not affected by moisture. Concrete leveling is used in residential, commercial, and industry offering immediate return to use. More benefits include less intrusive method of repair, lightweight product, eco friendly, and cost effective.
We serve central Iowa in the following locations: Des Moines,Nevada, Slater, Kelley, Ankeny, Grimes, Norwalk, West Des Moines, Johnston, Granger, Maxwell, Dallas Center, Urbandale, Ames, Madrid, Clive, Polk City, Pleasant Hill, Waukee, Altoona, Carlisle, Huxley, Bondurant, Windsor Heights and more
