WHY SPRAY FOAM INSULATION?

Air moves in and out of a home through every hole, crack, and crevice. Roughly 33% of air infiltrates through walls, ceiling, and floors. Adding an advanced insulation system is necessary to achieve optimal building performance. Lapolla is that advanced insulation system.

Spray foam insulation can maximize a homeowner’s investment by sealing the building envelope to stop conditioned indoor air from escaping and prevent unconditioned air from entering a home. Air exchange in and out of a home is a leading cause of escalated energy bills. The mechanical systems that heat and cool buildings are continuously operating; reducing extreme temperature variations saves on the overuse of mechanical systems and leads to lower energy bills.

WHERE DOES MY HOME LOSE ENERGY?

home-insulation-losing-energy-efficiency-insulation

Superior energy efficiency mostly depends on creating a better air seal. Wall insulation is a significant issue in home energy savings, but there are other factors that will lower home energy efficiency.


Doors and Windows

Moisture Control

Water and moisture in the building envelope is the single, greatest threat to building durability in residential construction. In addition to causing building-durability issues, moisture can create ideal conditions for mold growth, which can dramatically impact occupant health.

Ceilings, Outer Walls Floors and Crawlspaces

Air Leakage

Unsealed, responsible for about a third of the air leakage in a home.


As much as 40% of energy loss is due to air infiltration. Therefore, the most effective way to improve energy efficiency and comfort in your home is to seal it with foam.

LET’S COMPARE THE MOST POPULAR HOME INSULATION PRODUCTS

HOW IT WORKS

SPRAY FOAM INSULATION

Spray polyurethane foam acts as a barrier between the home and outside, creating a seal that can conform to any architectural design.

FIBERGLASS INSULATION

Traps air inside tiny glass fibers that contain small bubbles of air, which slows the transfer of heat.

CELLULOSE INSULATION

Made of shredded newspaper and a fire retardant chemical (borate), the paper is broken down into cellular fibers.

DOES IT SEAL AIR INSIDE YOUR HOME?

SPRAY FOAM INSULATION

Yes

FIBERGLASS INSULATION

No

CELLULOSE INSULATION

No

INSTALLATION METHOD

SPRAY FOAM INSULATION

Sprayed by a certified spray foam applicator, spray foam can adapt to any structural design.

FIBERGLASS INSULATION

Folded, wrapped and cut to place in walls. Slanted and/or high ceilings and outlets can lengthen installation time.

CELLULOSE INSULATION

Cellulose insulation is blown into walls. The material requires small amounts of water and glue to keep it in place.

R-VALUE

SPRAY FOAM INSULATION

6-6.6 per inch

FIBERGLASS INSULATION

2.2 per inch; loses up to R-Value 50% if it becomes damp

CELLULOSE INSULATION

3.5-3.8 per inch

PERFORMANCE IN COLD/HOT

SPRAY FOAM INSULATION

Excellent thermal properties and a sealant for your home that keeps warm and conditioned air in your home year round.

FIBERGLASS INSULATION

Doesn’t hold in heat well. Loses 40% of insulating capacity when outside temperatures are below 20° F.

CELLULOSE INSULATION

Doesn’t stop air leakage by sealing. Weather will cause wind and air pressure to enter through the small holes in the insulation.

ENERGY EFFICIENCY

SPRAY FOAM INSULATION

Most efficient.

FIBERGLASS INSULATION

Less efficient.

CELLULOSE INSULATION

Less efficient for your keeping your home insulated, even though it’s made from recycled newspaper.

HEALTH HAZARDS

SPRAY FOAM INSULATION

Polyurethane spray foam insulation consists of diisocyanate, which isn’t scientifically detectable after 1 hour of when the foam ins applied. Installing spray foam requires a professional certification and proper equipment to install it.

FIBERGLASS INSULATION

Fiberglass can be installed by anyone. Due to its long process for insulating around electrical outlets and windows, often insulation isn’t completed properly. Leaky ducts can pull loose fiberglass insulation and spread its particles throughout your home. Its small particles can be inhaled and cause serious respiratory conditions. The resin that bonds fiberglass can also emit small amounts of toxic fumes.

CELLULOSE INSULATION

Not sealing your home means dirt and moisture can cause mold, mildew and bacteria to grow. Blown cellulose insulation is prone to create dust that is then blown through cracks in the walls and creates a health hazard.

WHAT ARE THE BENEFITS OF SPRAY FOAM?

  • SAVES MONEY & ENERGY

    Installing spray foam insulation will help save you and your household money every year. The spray foam will seal air within the property and help prevent heat loss; this will make it cheaper to warm your home in the winter and help you save money every year. If you wish to sell your home in the future, buyers will find buying your property with a more attractive option. The savings begin immediately upon installation.

  • COMFORTS

    As our spray foam insulation is installed, you will find that your home is more comfortable than ever before. Drafts will be a thing of the past as they will be eliminated in your home. The seal created by the spray foam installation will help reduce cold and hot spots within the home as gaps are closed. This contributes to an even temperature within your property. If your home is near a noisy area, you will not have to suffer anymore as the spray foam seal will help reduce the effect of noise.

  • PROTECTS

    Lapolla’s AirTight spray foam insulation has many protective benefits for the home. It restricts air movement, which stops moisture accumulation so that the possibility of mould growth is less likely to occur. A huge benefit of spray foam insulation is that it helps deter pests from entering your home. Once the spray foam has solidified, pests of all kinds will find it difficult to enter your home through the now sealed areas.

  • HEALTHIER

    Many illnesses like asthma and allergies are often caused by airborne pollutants such as dust, dirt, carbon monoxide and many more. By choosing spray foam insulation, your home will be sealed from a wide range of pollutants in the air. Many customers notice a positive difference in their health after installation.

  • STRENGTHENS

    Spray foam insulation can help support the overall structure of your property. This is dependent on the application and thickness of the spray foam on installation.

  • RECLAIMS SPACE

    Current guidelines recommend up to 10 inches of insulation in your loft. This is usually added to the ground, rather than the roof line, which results in the loss of your storage area, due to not being able to refit floor boards after installation. By implementing spray foam insulation to the roof line, you regain the lost 10 inches, thus increasing storage, height and practicality. Reclaim your loft space!

HOME ENERGY ASSESSMENT

A home energy assessment helps owners determine where their house is losing energy and money – and how such problems can be corrected to make the home more energy efficient. The assessment will include checking for air leaks and inspecting your insulation, furnace and duct work. Inspections also include performing a blower door test and using an infrared camera.

For new homes, our insulators can provide a swift response at all phases of construction, whether you’re at the conceptual phase or if construction is already underway.

THE SCIENCE OF BUILDING

BUILDING SCIENCE PRINCIPLES

Practicing building science, also known as a “systems approach,” means accounting for the ways all building components interact, including the foundation, walls, lofts, roofs, doors, windows, insulation and mechanical systems. Doing so is critical to optimize building performance and prevent building failures.

Last but not least the building occupants must be educated to behave properly to limit energy losses; the most optimized building with the best insulation will be useless if the occupants do not respect the environment.

The principles of building science include:

  • Creating a continuous air barrier combined with proper mechanical ventilation
  • Providing thermal resistance and limiting heat bridges
  • Managing moisture
  • Improving indoor air quality
  • Using appropriate heating systems

Lapolla’s AirTight spray foam insulation addresses all of these principles to help building and design professionals practice building science techniques with ease. The benefits are verified through extensive research and testing performed on all Lapolla products worldwide.


HOW SPRAY FOAM PLAYS A VITAL ROLE

Building scientists are now stressing the importance of air barriers like spray foam insulation in building design and construction. This is partly because many buildings constructed in the past had no air barriers and experienced major failures in terms of moisture damage and mould caused by condensation, which stemmed from air leakage. In addition, research shows that without an air barrier, insulation cannot deliver optimal energy efficiency or comfort. This is why blower door tests are commonly required to measure air tightness in new or renovated buildings.


LIMITS OF U VALUE

U value measures insulation’s ability to limit conductive heat flow (heat that is transferred through it). But the primary method of heat transfer is not conductive heat flow — it’s air leakage, which can account for up to 40% of a property’s energy loss.

In addition, U value only does so much to prevent even conductive heat flow. Beyond a certain point, improving insulation U value makes very little difference, if any. Above a certain thickness of insulation material the heat flow reduction due to conduction reaches a plateau. In fact, the cost of improving U value alone can actually far outweigh the energy savings that result, meaning it will take much longer to break even.

Therefore, the best way to increase efficiency is not merely to improve U value, but rather to combine U value with an air barrier. Lapolla AirTight spray foam insulation provides both in a single step.
