What is Blow Insulation and Why Should You Use It?

Loose-fill blown-in cellulose blow up insulation is an easy dry install for attic walls, basement walls and other crawl spaces. Once the exterior finish has been installed, run a loose-fill through a blow-up machine, then cut out access holes by turning a sheet metal trowel upside down.

A filler material is then pressed into the hole using a metal press, and the filler penetrates the wall with the help of a trowel or a roller. After the inside is completed, it can either be installed on a tarp or by using an exterior membrane or reinforcement. An exterior membrane is used to seal and keep moisture out while reinforcement is used to secure the wall to the rest of the house.


Cellulose is used because it is more durable than wood, and the insulation can be applied over an extended period. The material can also be used for floors, decks, walls, windows and roofing. It is available in many colours and designs and has low cost and high energy efficiency properties. A fiberboard core is placed between two sheets of fibreglass insulation to make a strong, rigid barrier that will keep the heat and cold from escaping and to prevent heat loss.

If you are not sure what kind of insulation is best for your house, contact a local contractors’ office. They have experienced people who can take measurements and show you how to get the most for your money. The materials and installation process can be simplified for you if you have the right kind of contractor and the right amount of know-how.

Is It Up to Code?

If you are going to use blow insulation, you should check with your local building codes to make sure you follow the proper procedures. You should not go through with installing it yourself. Many of the companies that provide blow in insulating systems will allow you to install them for free, but you should hire a contractor that specializes in this field to make sure they understand the insulating process. This will save you both time and money since they will install it correctly and give you expert advice for the most effective use of the materials.

Blow insulating is great for rooms that don’t have direct exposure to direct sunlight, like a basement or attic. They are not recommended in rooms like closets, garages and laundry rooms because they will produce a lot of heat, even in wintertime. Because they are more expensive than traditional insulation systems, you will want to do your research before purchasing one.

It is best to check your local building codes to find out what types of insulating materials are allowed in your area. Many places require certain percentages of either wood or fiberboard as a prerequisite to having an adequate amount of insulation. If they do not, you can get by with using either one of these materials. or you could ask your local contractor to install the system for you. It’s not worth the risk.

Final Advice

To get the best bang for your buck, you may want to look into installing both types of insulation together. The cost of the entire installation would be much cheaper than the cost of one part of it alone. It is still worth investigating to make sure the company is certified to do this kind of work and to make sure their prices are reasonable.

Check with your home insurance carrier if they cover blow insulating materials. The good ones will cover some of the cost, but not all. If they don’t, you might want to check around with other insurance companies to find a cheaper policy.
