- Does spray foam add strength or rigidity to the structure?
Yes. According to tests conducted by the National Association of Home Builders, closed-cell spray foam insulation in wall cavity applications improved racking strength 330%-400% over fiberglass insulation. Roofing foams also add structural strength. The compression strength of closed-cell roofing foams is 40-50 pounds per inch while other insulations offer 20-25 pounds per inch.
- What is the cost of installing spray foam insulation and how is the cost derived?
There are a number of variables when determining the cost quote for your project, including:
- Size of area
- Existing structure vs. new construction
- Design and access to areas in need
We are happy to visit the building you’re looking to insulate to conduct a complimentary site analysis and explain the costs for your specific project.
- Does spray foam require attic venting?
No. Attic venting is a practice that initiated as a way to eliminate condensation from building up in the attic as a result of the temperature differences between the exterior and attic walls. Because of its moisture-barrier characteristics, spray foam insulation applied to the roof eliminates the need for cold air venting, lowering the overall annual costs.
- Does spray foam perform well on metal roofs?
Yes. However, prior to planning the project, be sure to check with the manufacturer of the metal roof to inquire about warranty considerations
- Is spray foam a moisture barrier?
Yes. Because closed-cell spray foam has cells that are closed, it will not absorb water when properly installed.
- How is spray foam installed?
Spray foam is sprayed into the wall cavity between the studs. While it’s applied as a liquid, it will expand to foam within seconds and fill gaps and open spaces–creating a permanent bond to the wood.
- Where would I need spray foam insulation most?
An on-site inspection or review of building plans would offer the greatest opportunity for deciding where spray foam insulation would best benefit your specific need.
- Does using spray foam insulation create big savings on fuel?
It certainly can. There are a number of factors that influence the use of fuel, ranging from building materials to building design to comfort and temperature preferences in the home. Typically, the fuel savings question is in regards to compensating for heat loss and gaps that contribute to air loss of the homes. When comparing use of fuel in accordance to air loss when comparing fiberglass products to spray foam, it has been tested and noted that close-cell spray foam fiberglass insulation offers 25%-40% more ‘R’ and offers significant advantages in gap filling and air loss control. The net gain of a tighter seal and higher ‘R’ value presents the opportunity of less fuel usage, which in turn can save a Maine home with 1,800 square feet around $447/year in fuel costs.
- How is spray foam insulation different than fiberglass insulation?
There are many differences, from active components to application to cost savings. While spray foam is more expensive than fiberglass and blown-in cellulose, it is the only insulation that offers an immediate reduction to energy costs due to its air barrier characteristics. Spray foam does not sag, compress, or settle over time and allows a greater protection against drafts and air loss in tight and hard to reach places.
No matter what form, fiberglass is not an air barrier and will not stop air leakage, especially at the tip and in tight places. Beyond that, the ‘R’ value or measure of insulation performance in the product is twice that of traditional fiberglass insulation products.
Specifically, spray foam offers:
- Higher ‘R’ value
- Liquid application to fill more gaps and create a tighter bond
- No chemical or physical changes over time
- Moisture barrier
- Adds structural strength to walls and roofs
- Can minimize sound transmission at greater levels
- Will the spray foam settle or change physically over time?
No. The closed-cell spray foam products we use do not change chemically or physically over time.
- Will I still get drafts through my walls?
Air loss and air drafts are a product of open spaces and unsealed barriers. Gaps of just 2% at the end of fiberglass insulation can result in 25%-40% reduction of ‘R’ value due to air leakage in the home. Reduced ‘R’ value means a decrease in insulation performance, an increase in drafts and air loss, and higher overall heating bills.
- Will using spray foam insulation make my home warmer?
On the basis of increasing warmth using the same level of fuel and comparing spray foam to rolled or blown-in insulation, the answer is “yes” as you’ll have less air and heat loss. When comparing use of fuel in accordance to air loss when comparing fiberglass products to spray foam, it has been tested and noted that close-cell spray foam fiberglass insulation offers 25%-40% more ‘R’ value and offers significant advantages in gap filling and air loss control. The net gain of a tighter seal and higher ‘R’ value presents the opportunity of less fuel usage, which in turn can save a Maine home with 1,800 square feet around $447/year in fuel costs.
- Does spray foam insulation deter rodents and insects?
While it is not a pest deterrent, spray foam offers no food value to rodents or pests and therefore would not be an attractant. Should a rodent or insect decide to gnaw through the material, there are no deterring factors of the product to prevent that from happening.
- Do I need to leave my home while you’re installing spray foam insulation?
It’s recommended that during the installation of a spray foam installation project that you not be in the building until the product has had time to fully cure. Curing time can depend on a number of factors, including temperature, thickness and humidity. Typically, curing can be reached in a range of 12-24 hours, depending on site conditions.
- Can you give me a comparison price on products?
Following an inspection of the location or the building plans, we are happy to offer a price quote that provides options for your specific needs and goals.
- Do you provide guidance as well as installation?
Yes. Our team will work with you and/or your builder or designer to discuss and plan out the best use of spray foam products and process for your specific building needs, schedule, budget and performance goals.
- Do people still use fiberglass?
Yes, fiberglass is still used. However, insulation is also made of other products such as polyurethane, which is extremely durable.
- What is a blower door and a thermal imaging test?
A thermal imaging test is done with an infrared camera to show where the leaks are in your walls, doors, windows, attics or wherever you may feel a breeze. The blower door test uses pressure to locate the leaks you may have.
