Walls Insulation

Wall Insulation

You are most likely aware that heat travels up, so you're probably wondering why the walls?  It's not up... So what's the purpose?

Well, think about it like this... While hot air does rise up, heat spreads all over. Traveling from a warmer area to a cooler area, by conduction and radiation.

Another way of looking at it is; trying to preserve air that you don't want to escape. What do you do? You, cover the whole surrounding space so the air doesn't escape. Same concept with your home. You have the AC or Heater going, you don't want the air to go in between any cracks that's money slipping away. The insulation around the walls will prevent this from happening.

Walls insulation is super important to keep the right temperature at your house. Failing to properly insulate your home can send your energy bill sky high, but the best time to do it is before you finish the walls. When you’re living in a home with exterior insulation that leaves something to be desired, your best option — short of uncovering the walls — is to blow insulation into them. The procedure involves making holes in the walls, either from inside or outside the house, but they are usually easy to patch.

Examples of where to insulate.

1. In unfinished attic spaces, insulate between and over the floor joists to seal off living spaces below. If the air distribution is in the attic space, then consider insulating the rafters to move the distribution into the conditioned space. (1A) attic access door
2. In finished attic rooms with or without dormer, insulate (2A) between the studs of "knee" walls, (2B) between the studs and rafters of exterior walls and roof, (2C) and ceilings with cold spaces above. (2D) Extend insulation into joist space to reduce air flows.
3. All exterior walls, including (3A) walls between living spaces and unheated garages, shed roofs, or storage areas; (3B) foundation walls above ground level; (3C) foundation walls in heated basements, full wall either interior or exterior.
4. Floors above cold spaces, such as vented crawl spaces and unheated garages. Also insulate (4A) any portion of the floor in a room that is cantilevered beyond the exterior wall below; (4B) slab floors built directly on the ground; (4C) as an alternative to floor insulation, foundation walls of unvented crawl spaces. (4D) Extend insulation into joist space to reduce air flows.
5. Band joists.

Wall Insulation Techniques

When installing wall insulation there are two methods we use here at Pure Eco Inc. The two techniques are entirely up to the customer.

Blown In Wall Insulation

Blown In Insulation is for existing walls.

  • We drill 2” holes about 16” apart on the surrounding outside/inside of the house/room(s).
  • Where the holes are placed, our installers insert a hose, and blow - in the insulation.
  • Once finished installing the insulation around the house/room(s), the installers will clean up any mess that may have been made.
  • Pure Eco Inc. does not patch and paint; this is a separate service. However, our representatives will point you to the right direction if requested. The patch and paint companies we recommend are always highly certified and professional.

Batt Wall Insulation

Placing Batts into your walls is good for renovations, or new construction.

  • The Batts are placed between studs in the house during renovation or new construction.
  • When there is pre-existing loose fill insulation, installers can place batts on top (optional).

Material Used for Installation:

  • Fiberglass
  • Cellulose
  • Roxul soundproofing

Fiberglass- Is most commonly used insulation in today's times. Fiberglass is made from finely woven silicon, glass powder, and from this shards of glass is formed. This material is non- flammable.

Cellulose- Most Eco Friendly of insulation. Cellulose is made from recycled cardboard, paper, and other similar material. You may think this is extremely flammable however, some studies have shown that this material might be an excellent product to minimize fire damage. The reason being, the compactness of the material, cellulose contains next to no oxygen within it. When you have no oxygen within the material, then this helps minimize the amount of damage that a fire can cause.

“Cellulose fiber insulation provided up to a 55% increase in fire resistance”
- National Research Canada July 13, 1999(2)


Roxul- Eco Friendly insulation. Made from rock based mineral fiber comprised from basalt rock and recycled slag. Roxul insulation capabilities are best known for being sound absorbent, fire resistant, water repellent, and dimensional stability.

Go Green

Protect the air and prevent climate change. Perhaps the most notable way that reducing energy helps the environment is by decreasing power plant emissions. To generate electricity, most power plants burn coal, crude oil or other fossil fuels. - (saveonenergy.com) (4)

Let’s Talk About Saving Money

“Reducing air leakage by air sealing, properly insulating your home, and replacing or improving your heating system are the three major ways of reducing your heating bills.”
-According to Energy.gov.

Coming to a Decision

Ask yourself the following questions.

Am I renovating, doing new construction, or in need for upkeep?

  • This will help determine the insulation technique.

What is the material of insulation that fits my preference? The most common or    environmental friendly?

  • Fiberglass, Cellulose, or Roxul

How much money am I spending a year?

  • Take a look on your energy bills for the past year what is adding up to?

Do I want to be part of the Go Green Act?

  • Do you care about our environment for today and our future?

Do I want to invest a little to gain so much more?

Blowing-In from Inside

The machine that blows the fiberglass or cellulose insulation into the walls has a large hopper to hold material and a long hose with a nozzle about 2 inches in diameter. Pure Eco Inc. makes holes for the nozzle — usually with a hole saw — between each pair of studs in the wall we’re filling. The holes are usually mid-way up the wall and at the top to provide regulate the density in each wall cavity. Patching the holes isn’t difficult to do since we save each cut-out. We are not responsible for patch and paint. The professional who will be hired to perform this service can fit each cut-out back in place and cover it with drywall tape and joint compound.

Blowing-In from Outside

If you live in a house with plaster walls, it may be preferable to blow insulation from outside, as long as the house has vinyl, aluminum or wood siding that you can easily remove. The procedure is the same, except that we make the holes in the plywood sheathing. A good way to patch the holes is to fit each cut-out back into the hole from which the professional you hire took it and cover it with patching compound, which becomes rock-hard when it sets. Cover the patch with tar paper and replace the siding that you removed to access the sheathing.
