Blown-In insulation

Attic insulation is key to controlling your home temperature throughout the year. Blown-in insulation is one of the most effective ways to insulate your attic. We often recommend blown-in insulation for unfinished attics. It’s an affordable choice that involves a large tube that blows out insulation, which can be evenly dispersed to hard-to-reach areas. Blown-in insulation can be made of cellulose, fiberglass, or similar materials that are thick, dense, and lumpy in consistency. The pro of blown-in attic insulation is that it can fill small spaces and will add protection against insects and vermin. The two main types of blown-in insulation are cellulose and fiberglass. With a proper blower machine, installation is simple and quick. 

closed cell spray foam insulation

Spray foam insulation can be applied to rafters or the attic floor. Because a sealed attic space doesn't have any contact with the outside air, sometimes spray foam is applied only to the attic floor to replace other forms of insulation like fiberglass and cellulose. Spray foam is created by combining isocyanate and polyol resin, which makes polyurethane. This has been used as an insulation material since the 1970s, and it is effective because the final foam contains a low-conductivity gas in its cells. Closed-cell spray foam creates a proper air seal and is considered one of the best insulating materials. However, each house is different so not every house will perform with certain insulation materials as well as others. It is always recommended to speak with a professional before deciding which insulation is best. 

cellulose insulation

Cellulose is made of recycled materials and can be used to fill enclosed spaces like attics. Cellulose is used as insulation because it is plentiful and packs tighter than fiberglass insulation. Cellulose can be blown into your attic with our special blower machine. Cellulose is considered an eco-friendly product compared to fiberglass and foam insulation.  The R-value of cellulose insulation is significantly higher than fiberglass, and the higher the R-value, the better the insulation is at preserving thermal efficiency, meaning your home temperature will be more stable. 

Batts and Rolls insulation

Also known as blanket insulation, batt insulation comes in pre-cut, flat pieces that look like a blanket. It prevents heat and cold from passing through. Both products are equally effective in insulating your ceiling space. The main difference is the method of installing the insulation. While rolls can be rolled out between the ceiling joists, insulation batts are installed in pieces. If you want to install insulation across the joists to eliminate thermal bridging, and if your ceiling space has very few obstacles and a lot of room to work with, installing insulation rolls may be a suitable option. However, if your ceiling is tight and has some additional obstacles, such as ventilation pipes or electrical cables, then it would be easier to install insulation batts, as rolled insulation will tend to catch more on these obstructions. 

$1,200 Savings with Home Energy Tax Credits for Insulation Upgrades

Are you planning to upgrade your home’s insulation? Now might be an excellent opportunity to not only improve your home’s energy efficiency but also take advantage of financial benefits through tax credits. Homeowners who enhance their insulation qualify for significant savings with home energy tax credits.

Upgrading your home’s insulation can lead to eligibility for a tax credit of up to $1,200. This incentive is designed to encourage homeowners to invest in energy-efficient home improvements. By installing new insulation, you can lower your energy bills and reduce your carbon footprint while getting some money back during tax season.

To take advantage of these tax breaks, make sure your insulation upgrade meets the specific requirements set by the IRS. Additionally, keep all receipts and documentation related to the upgrade, as you will need them when filing for the credits. Check with a tax professional or refer to the latest IRS guidelines to ensure you meet all the qualifications for claiming your credit.

By acting now, you can make a smart investment that not only enhances the comfort of your home but also supports environmental sustainability and offers financial advantages.

How can attic insulation save money on energy bills in Seattle homes?

If your attic is poorly insulated or not insulated at all, you’ll pay more in utility costs. Investing in proper attic insulation can lead to significant energy savings, typically ranging from 30% to 80% depending on the state of any existing insulation. This substantial reduction in energy use is primarily due to enhanced efficiency, as the insulation helps maintain a consistent temperature within your home. Furthermore, such improvements often pay for themselves within months, presenting not just a reduction in energy bills but an excellent return on investment. Homeowners in Seattle have particularly noted these benefits, considering the area’s climate.

what are the benefits of attic insulation in seattle?


Did you know that heating and cooling can make up 50% to 70% of the energy used in the average American home? If your attic is poorly insulated or not insulated at all, you’ll pay more in utility costs. In Seattle, homes with proper attic insulation enjoy significant reductions in their energy bills. Investing in quality attic insulation can lead to an average energy savings of 30% – 80%, depending on the condition of old insulation. This substantial decrease in energy expenditure means that the insulation installation pays for itself within just a few months.


Attic insulation is one of the most effective ways to ensure your home is comfortable year-round. It can allow heat to flow from warmer areas to colder spaces, maintaining a balanced temperature throughout your dwelling. This is especially beneficial in Seattle's variable climate, providing warmth during cool, damp winters and coolness during mild summers.


Since insulating your attic slows down heat buildup, it will prevent mold that often accumulates in moist, cool areas. New insulation is a great way to protect your overall home structure. Mold and mildew, which thrive in the dim, warm conditions of an inadequately insulated attic, can drastically decrease the air quality and cause decay to your home’s structure. By choosing the right insulation and considering additional measures like prescriptive air sealing and duct sealing, you can lock out moisture and keep your attic toxin-free.


Unfortunately, old insulation can serve as a breeding ground for mold and mildew, leading to poor air quality. With new insulation, you can drastically improve the air you and your family breathe. Prescriptive measures such as air sealing and using the appropriate insulation materials not only prevent the growth of harmful organisms but also ensure that the air within your home remains clean and healthy. This proactive approach protects not just your health but also enhances the overall livability of your space.

how can rodents or animals in the attic lead to health hazards?


Rodents or animals in the attic can lead to health hazards due to the potential contamination of the living space. Their presence can result in the spread of diseases, allergens, and parasites, impacting the air quality and overall health of individuals within the home. Specifically, the infiltration of pests like rats, raccoons, and bats can introduce dangerous airborne bacteria and allergens.

Moreover, their droppings and urine can create a breeding ground for harmful bacteria and mold, further exacerbating health risks. If these animals damage air ducts or contaminate insulation, the circulation of contaminated air could lead to unexplained health issues, including itching from mites or flea bites, aggravated asthma, or an increase in allergies. This situation is particularly concerning for vulnerable groups such as small children and the elderly, who may have lowered immunity.

Proper cleaning and removal of debris by professionals are essential to ensure a clean and healthy living environment. Ensuring that your attic is free from pests and their residues not only maintains the structural integrity of your home but also safeguards the health of all its occupants.

How does attic insulation help keep moisture out of your Seattle home?

Seattle’s damp climate can pose significant challenges for homeowners, especially when it comes to managing moisture in the attic. Proper attic insulation is a crucial defense against these issues.

Firstly, insulation acts as a barrier, preventing outdoor moisture from seeping into your attic. Without effective insulation, water can infiltrate through cracks and holes, leading to damp conditions. These conditions are ideal for mold and mildew to flourish, which not only compromises air quality but also weakens your home’s structural integrity.

Effective attic insulation also involves airtight sealing and duct sealing. This comprehensive approach locks out moisture and ensures that your attic remains dry. It helps to maintain a consistent indoor environment, preventing the warm, moist air from condensing on cooler surfaces. This proactive measure keeps mold and mildew at bay, thus protecting both your health and property.

In summary, the right attic insulation keeps your Seattle home dry by creating a moisture-resistant barrier and maintaining a stable indoor climate. This simple yet essential step can save you from extensive repairs and health hazards down the line.
