WHAT IS SPRAY FOAM?

Save money

Icynene spray foam insulation installed by NGI is a premium product that pays for itself quickly.

Be healthy

By air sealing your home, you can help block pollutants that can affect your health.

Be comfortable

Air sealing your home using Icynene spray foam insulation creates a cocoon effect, increasing the comfort of your home.

Protect your home

You want your home to last a long time and spray foam insulation can help.

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 AND CLOSED CELL

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:

Here are some differences:

R VALUES

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.

BARRIERS

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).
