By air sealing your home, you can help block pollutants that can affect your health.
- Reduce dangers of respiratory distress – allergies, asthma, and certain chemical sensitivities can be caused by natural airborne irritants.
- Minimize pollutants – dust and dirt, mold and moisture, radon, exhaust fumes, and carbon monoxide are reduced by air sealing, to keep your home and air clean.
- Protect against mold growth – minimizing the flow of random airborne moisture entering your home help you protect against mold growth that may lead to conditions such as asthma and allergies and cause symptoms such as itchy eyes, sneezing, and coughing.
Air sealing your home using Icynene spray foam insulation creates a cocoon effect, increasing the comfort of your home.
- Reduce drafts – a home without spray foam insulation loses enough air each day to fill two blimps.
- Avoid hot and cold spots – seal between heated/cooled living spaces and unconditioned spaces such as garages and basements, to maintain even temperatures throughout your home.
- Reduce noise – Icynene open-cell spray foam can help reduce sound from noisy indoor rooms such as media rooms and laundry rooms, outdoor noises such as traffic and playgrounds, and transferred noise such as flushing toilets.
Protect your home
You want your home to last a long time and spray foam insulation can help.
- Protect against moisture – 99% of the moisture that enters the walls of your home is carried in the air. You can reduce the amount of moisture that gets into your home, and the mold and moisture damage that can come from it, by air sealing it with Icynene spray foam insulation.
- Keep pests out – Icynene spray foam insulation does not provide a source of food for rodents, termites, or other nasty critters. It also doesn’t make for good nests, and as a solid material it’s difficult to pass through, helping protect your home from critters.
- Structural Integrity- Depending on your application, and the product you choose, Icynene can offer extra structural stability to your walls which can’t be achieved using other traditional forms of insulation.
Spray vs. traditional
Spray foam stops air leakage
Spray foam insulation is like a warm windbreaker jacket. The spray foam stops the cold air from passing through.
Fiberglass and cellulose insulation are like a wool sweater – if there’s any breeze, it doesn’t keep you warm. Even if they’re very thick to give an extremely high R-value, they’ll still let air leak out and increase your energy bill.
Spray foam is an innovative material
Spray foam insulation is a modern material that’s been used for over 25 years
Fiberglass is an old technology, and cellulose is little more than shredded newspaper.
Spray foam fills gaps
Spray foam insulation expands up to 100 times to fill gaps, ensuring maximum insulation.
Fiberglass and cellulose are extremely difficult to install perfectly. The spaces that are left add up to the size of a basketball in the average home and leak enough air to fill two blimps each day!
Spray foam protects from water
Many open cell spray foam (such as Icynene LD-C-50) drains water rather than holding it, and most closed cell spray foam doesn’t let it in at all.
Cellulose is made from shredded newspaper, and drinks up water. Fiberglass batts and cellulose don’t repel water, the water stays in place and may damage the building as well as reducing how well the insulation works. This is one of the leading contributors to mold development and it also decreases R-values, meaning you spend more on energy.
Spray foam stays in place
Spray foam stays in place – it doesn’t settle or sag, vertically or horizontally. It moves with the house as it settles. Spray foam insulation is completely solid when it sets, doesn’t produce any dust, and doesn’t let dust or other pollutants pass through to your home.
Fiberglass and cellulose settle and sag over time, leaving gaps that compromise insulation. Fiberglass and cellulose can be dusty and allow dust and other pollutants to enter the building.
Spray foam is healthier
Many spray foams (such as Icynene LD-C-50) don’t contain formaldehyde, HCFCs, HFAs, or HFCs, and doesn’t give off harmful emissions once installed.
Most fiberglass contains formaldehyde, and may emit formaldehyde fumes into your home.
Spray foam doesn’t attract pests
Many spray foams do not provide a source of food for rodents, termites, or other pests. They also doesn’t make for good nests. Fiberglass and cellulose can be torn apart by pests, and some even use them for nesting.
Spray foam isn’t easily damaged
Spray foams harden to a dense material that isn’t easily damaged. Exposed fiberglass and cellulose are easily damaged – insulation in areas such as basements and attics may be compromised by cats, children, moving boxes around, and other general usage.
Open cell and closed cell spray foam insulation are both effective solutions–one or the other may work better in different climates and parts of the home.
Open Cell and Closed Cell: Similarities and differences
Both spray foam types:
- Spray in to fill all gaps and holes
- Form an air barrier to stop drafts and air leakage
- Don’t provide a food source for mold (check with your spray foam manufacturer)
- Don’t provide a food source for pests
Here are some differences:
- “Breathes” — it is vapor permeable and this can let your home dry out.
- Moderate cost $$ per square foot
- Reduces sound transmission so you don’t hear from one room to the next
- Flexible – moves with your house to ensure there are no gaps in your insulation and no loss of air seal
- Doesn’t absorb water; lets it drain down through the insulation (check with your spray foam manufacturer)
- Good thermal insulation – R-3.7 per inch thickness. A 3.5 inch thickness is suggested to get an air barrier
- Doesn’t “Breathe” – acts as a vapor retarder
- Higher cost $$$ per square foot in most applications
- Lower sound reduction
- Stays rigid – helps wall strength; impact resistant.
- Doesn”t let water in (check with your spray foam manufacturer) – this is an advantage in flood zones. Great for flood prone areas
- Great thermal insulation – R-6.0 per inch thickness
Don’t get blinded by high insulation R-values
R-value only measures how well insulation resists heat movement through the insulation material (called conductive heat flow). It doesn’t take into account how well the material stops heat movement from convection, carried in the air. Air leakage can cause up to half of your home’s energy loss.
Reduce energy costs by sealing air in
R-value doesn’t measure air flow through a material, so without air sealing your home could lose a lot of heated or cooled air. Icynene spray foam insulation seals your home as well as providing an effective R-value.
More or Thicker Insulation and Higher R-Values Are Not Always Better
Did you know 93% of conductive heat flow is already stopped by R-12 insulation? Upgrading from R-12 to R-40 reduces conductive heat flow by only another 5%. If you use very high r value fiberglass or very high r value cellulose, you may still get high heating and cooling costs. Icynene spray foam insulation can provide a high enough R-value plus offering air sealing to maximize comfort and minimize your energy bills.
When using spray foam insulation, you sometimes need to include other materials to meet code. Your builder or NGI will check with the local code official to ensure that everything will meet their requirements.
Thermal and ignition barriers – protect against fire
Icynene spray foam is a Class 1 material with a flame spread of less than or equal to 25. Also, according to third party testing, electrical wires installed by a licensed professional don’t overheat when encased in Icynene spray foam insulation.
Local codes usually require additional protection against fire.
Occupied spaces in your home: Thermal barriers and spray foam insulation
If the spray foam insulation is used in any part of your home used as a living space, it should have a thermal barrier that has been tested and approved for use with the spray foam. Thermal barriers are designed to protect against direct fire damage to spray foam adjacent to living areas for at least 15 minutes. A thermal barrier might be a material such sheet rock, plywood or particleboard, or a painted-on fire proof coating.
Unoccupied spaces in your home: Ignition barriers and spray foam insulation
If the spray foam insulation is used in any unoccupied part of your home, such as an unoccupied attic or crawl space, it should have an ignition barrier that has been tested and approved for use with the spray foam. An ignition barrier is a fire protective coating designed to inhibit or prevent the start and spread of fire from a spark or direct heat on the spray foam surface. Ignition barriers are usually spray-on or brush-on coatings.
Vapor barriers and vapor diffusion retarders – Protect against moisture
Cold climates: Vapor barriers and spray foam insulation
If you’re using an open-cell spray foam insulation such as Icynene LD-C-50 in a cold climate, you’re usually required to have a vapor barrier or vapor diffusion retarder on the interior (warm in the winter) side of the insulation. This blocks moisture movement from inside your house to the outside, where it may condense and freeze. Vapor barriers / vapor diffusion retarders are typically membranes (plastic sheets) or brush-on coatings.
Closed-cell spray foam insulation typically doesn’t require a vapor barrier or vapor diffusion retarder.
Hot and humid climates: Vapor barriers and spray foam insulation
If you’re using an open-cell spray foam insulation such as Icynene LD-C-50, in a hot and humid climate you?re usually required to have a vapor barrier or vapor diffusion retarder on the exterior side of the insulation. This blocks moisture movement from outside your house to the inside, where it can cause mold and increase the amount of energy you need to cool your home. Vapor barriers / vapor diffusion retarders are typically membranes (plastic sheets) or brush-on coatings.
Closed-cell spray foam insulation typically doesn’t require a vapor barrier or vapor diffusion retarder.
Hot and dry climates: No vapor barrier
Vapor barriers or vapor diffusion retarders aren’t generally required in hot and dry climates.
Icynene spray foam insulation: More than just insulation
Going beyond traditional insulation, Icynene spray foam is also an air barrier that completely fills any crack or crevice to provide a superior air seal. Go with a complete insulation and air barrier solution that often pays for itself within three to four years (on average).
