Blow In Attic Insulation: Things to remember

Posted by Johnny Baker on July 10th, 2018

Attic insulation significantly reduces heating costs by up to 30%. However, not all used insulation vacuum machines and insulation techniques are equal. The first way to ensure that the insulation is correct is to ensure that the thermal resistance index R is greater than 6. In this article you will came to know about the methods of insulation of the attic by blowing.

However, it is essential to adapt its insulation technique to its type of height:

  • For lost roof spaces, the insulation comes to rest on the floor between the floor and the frame.
  • For converted attics, the cool insulation vacuum is placed between the roof and plasterboard.

The attic insulation technique by blowing is only possible for attic spaces. To isolate lost attics two techniques are possible:

  • By spreading: for this it will be necessary to mount by hand the insulator then to distribute it by means of a rake.
  • By blowing: in this case everything is done mechanically using an insulation removal vacuum pump and a pipe that will blow the insulation in your attic. This technique allows you to blow directly from the outside to your attic insulation without going through the house.

Attic insulation by blowing: advice before starting

The insulation improves the thermal and acoustic performance of his home. Depending on where you live and where you live, the choice of insulation is important. For a little reminder, a thermal insulation protects both the hot and the cold. Good insulation in hot areas will therefore cool the house. Moreover, if you live in a noisy area, the insulation also has a phonic coefficient.

Attic insulation by blowing: Monitor the condition of the floor

The insulation must be placed on a sound support. If your floor has wet spots, treat them and repair them before installing the insulation. Once the problems are fixed, let the floor dry and make sure the problem has been solved. Then, it will be possible to proceed to the insulation of the attic by blowing.

Attic insulation by blowing: Some tips

In order to limit thermal bridging and ensure continuity in the insulation, the holes and openings in the ceilings must be filled. If an access door is present, it is important to isolate it with materials of the same thermal property as the insulation used for the insulation of the attic space lost.

The electrical boxes will also have to be insulated and protected. Do not put them in immediate contact with the used insulation vacuum for removal; it is better to separate them.

If ventilation is present in your attic, it must be made sure that it is at a sufficient height so as not to suck the wool otherwise you have to move it. For windy areas, prefer wool with good resistance to wind so that it does not move in time. Indeed, once available, your insulation will not move.

Price of attic insulation by blowing

This type of work requires tools and equipment. In addition, for these insulation works you can benefit from 30% tax credit.

About us:- As such, we recommend that you hire a professional. What will influence the price is the type of material chosen as well as the coefficient of thermal resistance. In general it is necessary to count between 20 and 40 dollar per square meter laid for this type of work.
