    There are two primary ways to install foam insulation in San Diego and Orange County homes. Spray foam is applied as a liquid to exterior walls that are in direct contact with exterior areas and don’t have enclosed spaces within them for layers of insulation. Crawlspaces and attics are typical targets of spray foam insulation, which expands after application by as much as 100 times its volume. Insulation is literally injected through the wall surface, where it fills in closed cavities and cracks, forms around pipes and wires, and covers all of the gaps and crevices. At Attic Projects Company, our spray foam and injection foam insulation is:

    Signs to Watch For

    A few tell-tale signs that your house needs to have its insulation replaced or upgraded, whether through injection or spray-foam application.

    Higher utility bills. If HVAC costs are spiraling upward in your energy bill, it might be a sign that your insulation is no longer helping to keep your home warm or cold enough.

    Hard-to-control home temperatures. If managing your thermostat settings for ideal home temperature is getting to be a constant problem, poor insulation may be the culprit.

    Vast temperature differences from room to room. If one bedroom in your home is drastically warmer or colder than another bedroom, or other similar living spaces are wildly different in temperature, your insulation may need to be serviced.

    Benefits of Insulation Injections and Spray Foam Insulation

    Lower utility bills. Injected insulation and spray foam insulation make it easier to control a home’s temperature with less energy, which results in lower utility bills.

    More comfortable temperatures. By preventing air leakage through small gaps, injected insulation and spray foam insulation keep home temperatures warmer in winter and cooler in summer.

    Reduces carbon footprint. Insulation doesn’t require outside energy sources to work, which means it has no detrimental effects on the environment.

    Easy installation. Injected insulation is applied through sparse, discreet holes drilled into the wall that are easily patched up and cleaned once the installation is over. There’s far less mess or cleanup than with other options.

    Long-lasting. When properly installed, foam insulation can last for as long as most families are likely to live in their home — usually at least 30 years, but potentially 50 or even longer.

    Insulation Injection vs Spray Foam Insulation

    For the most part, injection and spray foam insulation use the same base material. They both apply insulation that serves as an air sealant to make your home’s air more comfortable and clean.

    There are differences in how the insulating foam is applied. For insulation injection, less prep work is involved. Crews simply drill a few holes in walls, inject the insulation with special tools, then close and clean them up.

    With the somewhat more invasive spray foam, crews must remove any old traces of fiberglass and cellulose before applying the insulation. They must also move any furnishings and belongings around and cover them in plastic.

    Frequently Asked Questions:

    How do I know if I need new insulation?

    Signs you need new insulation may include higher utility bills and that the temperature is difficult to control within your home. Also, if you have some rooms that get cold while other rooms get hot, you may have an issue with your current insulation. If you are experiencing any of these signs, you may have old or damaged insulation and should call Attic Projects to conduct a free inspection.

    What is insulation injection? Why would I want this instead of spray foam insulation?

    Insulation injection allows us to insert insulation in all the nooks and crannies between the walls that spray foam may not be able to fill. We recommend insulation injections over spray foam because it fills more space and doesn’t release the chemicals known as off-gassing” that you get with spray foam.

    Why would I want to replace old insulation with insulation injection?

    Getting rid of damaged or old insulation and replacing it with insulation injection will help lower your utility costs, keep the temperature in your home comfortable, reduce your carbon footprint, and the insulation is made to last for years down the road.

    Should I hire a professional to install my new insulation?

    Yes! Instead of installing the insulation yourself, you should hire the professionals at Attic Projects to install it for you. When you hire us, we will come out and conduct a full free inspection to ensure you are getting the right insulation and that no other issues are going on in your attic or crawl space.

At Attic Projects, we not only humanely remove the rodents and pests from your home, but we also rodent-proof your home so they can’t come back. In order to keep the pests and rodents out permanently, you have to close up every entry point that they may squeeze into. Call Attic Projects today to get your free estimate.
