The walls are one of the most significant sources of air leaks inside your home. Insulating them helps maximize energy efficiency and provides additional comfort for your family.

Newer home construction typically includes state-of-the-art insulation, but homes built decades ago will need wall insulation installed as part of a home improvement renovation.

When it comes to your Seattle home, you want to ensure the wall insulation is good. You’ll want to know that it will deliver the best results possible, so leave it to the pros. Trust an experienced contractor from Attic Projects for your wall insulation services.


Most people know that wall insulation slows down the loss of your home’s heat. But it does much more than that. Many homeowners use insulation materials to create a sound barrier between rooms. Although it won’t become totally soundproof, interior wall insulation can reduce noise transfer.

Interior and exterior wall insulation reduce the rate of heat transfer between rooms. Without insulation, air will enter and exit your home easily, causing the temperature to increase and decrease to uncomfortable levels. This fluctuation forces your HVAC unit to work harder to keep your home comfortable and drives up your monthly energy bills.

The best insulation material for your home depends on the local climate, budget, and installation area. Common materials used are as follows:

Spray foam insulation is made from polyurethane and applied using a special sprayer. It easily gets into tight spaces, making it an ideal insulation material for cold climates.

Injection insulation gets inserted into your wall’s cavity to create an air seal, stopping drafts from moving inside your home.

Blown-in insulation is made of fiberglass spun into fibers or cellulose. This material gets installed using a blower machine.

Foam board insulation is made of dense material and may be laminated on either side.


Insulation material is rated according to its R-value. This number tells you how well that material will prevent heat from leaving or entering your home. R-value varies based on the insulation material’s type, thickness, and density. The higher the R-value, the more protection it provides for your home.

R-values typically range from R10 to R60. Higher numbers are best for areas that need more insulation, like an attic. However, insulation with a lower R-value could provide comparable insulation to materials with higher values when more is used or layered.

The R-value per inch varies between brands, types of insulation, and how it was installed. However, you can expect insulation to fall within these ranges:

You can always increase your R-value by applying another layer of material.

Poorly, non-insulated walls allow heat to escape your home, making it more challenging for your HVAC system to keep a comfortable temperature. This means it must work harder to maintain a warm home, forcing your energy bills to skyrocket. Adding insulation to your walls saves you money by keeping heat inside.

It’s hard to determine an exact estimate for how much money you save after having wall installation installed. It depends on the type of insulation you have installed, along with the total R-value it represents.

You can find the best insulation for your home and begin saving money with Attic Project.


If your home could benefit from wall insulation, Attic Project is here to help. We offer free inspections for your home, where we’ll answer all of your questions. A qualified contractor will assess your walls and identify any unknown issues to create a full picture of your requested insulation project.

Attic Insulation

Like your walls, choosing the correct attic insulation for your home is crucial to your comfort and energy savings. Before we complete any installation, we’ll thoroughly inspect your attic space to ensure there aren’t any issues that need addressing, like rodents or mold. Don’t continue letting air escape through your roof!

Crawl Space Insulation

Insulating your crawl space is as crucial as protecting the rest of your home. At Attic Projects in Seattle, we adequately install and seal the most vital areas of your home: floors, walls, and rim joists. Our services will help keep the pests and mold out of your crawl space.



Insulating finished walls can be tricky because it’s challenging to get insulation inside the wall and between the studs and cavities. It is easiest to install insulation when the studs are still visible before the drywall or another wall material is placed. But we’ve got the necessary tools to get the job done right.

Attic Projects’ Professionals

Our experts understand that crawl space insulation is as strong as its weakest points. Our team will target the most vulnerable spots in your crawl space effectively and ensure that there are zero weaknesses left in your crawl space. During the installation, we guarantee your walls, floors, and joists will be properly insulated.

Let our professional team improve the quality of your crawl space and home by keeping out moisture, air drafts, pests, and rodents all while keeping the cool or hot air inside.
