what are the main types of insulation commonly used in residential wall insulation projects?

Each type of insulation has its own benefits and appropriate applications depending on the specific needs of the building and climate considerations. Whether you’re looking to upgrade old insulation or install new insulation, understanding these options can help you make an informed decision.

BLOWN IN INSULATION

Blown-in insulation is a method of insulating walls that involves blowing Cellulose into wall cavities through holes 1-2 ½ inches wide. This is the preferred method for insulating existing, closed-up walls, as it offers a far easier method of improving the R-value of walls than installing fiberglass batts.

TWO MAIN TYPES OF BLOWN-IN INSULATION

Cellulose:
Cellulose insulation is made of recycled paper and has an R-value of 3.5-.38
Loose-Fill Fiberglass:
Fiberglass insulation has an R-value of 2.2-2.69 per inch, meaning you will need more fiberglass insulation to get the same effects of cellulose.

EXTERIOR WALLS

For exterior walls, we use Owens Corning fiberglass insulation. It’s a formaldehyde-free insulation that works well on exterior walls. Installing insulation in exterior walls also requires drilling two-inch holes. If your exterior walls have siding, we’ll need to remove a row of it to access the plywood.
Once we’ve installed the insulation, we’ll cover the holes with a wooden or foam plug. If we’ve needed to remove siding, we’ll put it back in place.

fOAM BOARD

Rigid foam board has relatively high insulation value and flexibility. It is light, solid, and usable with different wall surfaces. Foam board insulation offers a very good R-value which makes it suitable for residential or even commercial purposes. It has a high thermal insulating property for its thickness and can be appropriate where there is a lack of space.  

INTERIOR WALL INSULATION PRODUCTS

For interior walls, the products we use are batts made from materials such as fiberglass or mineral wool.
  Rigid Foam Board:
Foam boards and rigid foam boards reduce the amount of heat conducted through the wood, wall studs, and other elements that make up a home's structure.
Fiberglass Batts:
Fiberglass batts are the most cost-effective. However, they must be installed properly to avoid small gaps that can reduce efficiency by as much as 25 percent.
Rockwool:
Rockwoll is more expensive than fiberglass and typically comes in rolls of batts that are pre-cut. Providing up to R-3.3 per inch of thickness.

BATT INSULATION PRODUCTS

The most common type of batt insulation is fiberglass, but other materials can include mineral rock or slag wool.
Fiberglass Batt:
 Made of fibrous glass wool encased by an outer layer made from paper, plastic, metal, or other textile materials. They come in pre-cut sections and come in different thicknesses and widths. 
Mineral Wool:
This type of insulation is fire and water-resistant.  Mineral wool can withstand extreme heat better than any other type of insulation. This gives your home better protection against flame spread. Also, mineral wool does not absorb water, which means it will stay intact even when wet.

BATT INSULATION

Batt insulation is fitted between the studs of an exterior wall. Some products are available with a facing including kraft paper vinyl, or foil which will provide an additional air or vapor barrier. 

INTERIOR WALLS

Internal wall insulation has more than one advantage. If you choose to insulate your interior walls it can significantly reduce heating and cooling costs, making it easier to maintain temperatures in your home which will put less stress on your HVAC system.  Interior wall insulation can potentially reduce noise from room to room by creating essentially a barrier between each room that is insulated.

EXTERIOR WALL INSULATION PRODUCTS

There are many different types of insulation you can use when you renovate or upgrade your home's exterior walls. Exterior walls can either be insulated with insulation blankets and pre-cut batts or blown-in. Unfaced or faced fiberglass insulation Regular or high-density fiberglass batts Rigid foam board Spray foam up to two inches thick Blown-in cellulose Blown-in fiberglass Roxul (a fireproof and water-repellent insulation solution)

Stress-free process

from start to finish

Blown-in wall insulation offers several compelling features and benefits that make it an appealing choice for home and building insulation. 

WHAT ARE THE CHARACTERISTICS AND BENEFITS OF BLOWN-IN CELLULOSE INSULATION?

Overall, blown-in cellulose insulation is not only dense, contributing to its sound reduction and fire resistance, but it also supports environmental sustainability and personal comfort.

1

SOUND ABSORPTION

Cellulose has excellent sound dampening properties, making it ideal for reducing noise penetration in a building.

2

PEST RESISTANCE

It is inherently resistant to pests, lowering the risk of infestations.

3

FIRE SAFETY

With a Class 1 fire rating, cellulose insulation provides a high level of fire resistance, the top classification available.

4

ENVIRONMENTAL FRIENDLINESS

Featuring approximately 85% recycled content, it’s a sustainable option for those looking to minimize environmental impact.

5

ALLERGY-FRIENDLY

Unlike some alternatives, cellulose does not irritate the skin, providing a user-friendly installation experience. 

6

EFFICIENT INSULATION VALUE

With an R-value of about 3.4 per inch, cellulose insulation offers superior thermal insulation compared to many options like fiberglass while being slightly less than closed-cell spray foam.

Frequently Asked Questions

Wall insulation is added material to the walls of your home or building that reduces heat transfer which increases energy savings and home comfort. 

Wall insulation material is unique to each house wall insulation may consist of cellulose, fiberglass, foam board, or mineral wool. 

Benefits of wall insulation that will accrue when installed include less wear and tear on the HVAC system, more efficient use of energy, better comfort, less damage to the environment, and potential increased property value.  

Insulating a wall without removing the drywall, also called retrofit insulation or re-insulation, is useful for homes with existing drywall. Instead of knocking down the existing drywall and then installing new drywall, you can save on the cost of your project by navigating around your drywall.
