What are the different types of insulation? And how to protect yourself during insulation work?

From vegetable origin, cellulose wadding is made from recycled newspapers or paper sludge from printing facilities. It is treated to resist fire, insects, and fungi.

Blowing insulation

Blowing insulation is used in most cases to insulate attics. After having found an access to the attic (which can be inside or outside), the insulation is projected on the whole floor of the attic and even in the most difficult to access corners, unlike insulation done manually.  It allows to obtain a perfectly uniform insulating layer, and thus to eliminate at most the thermal bridges. Maximum efficiency for lost and unfinished attics.

DEFINITION
Consists in spreading fibers pneumatically and dry on an open horizontal surface, especially in attics that can be converted or lost.

ADVANTAGES

• Total rupture of thermal bridges
• Adapted to difficult places
• Fast execution
• Freedom of thickness according to thermal regulations

POSSIBLE PRODUCTS      
Cellulose wadding, glass wool, rock wool, hemp, wood.

Insufflation of the walls

This technique is ideal for renovation because it allows to keep existing partitions without having to remove them. This can be beneficial for wall insulation, roof insulation under a slope, floor insulation, etc. The main advantage of this technique is that the insulation will be perfectly adapted to the different gaps behind the wall.

DEFINITION
It consists in injecting under pressure and dry the fibers in a closed box, such as floors, walls, slopes and roofs…

ADVANTAGES

• Total rupture of thermal bridges
• High density (variable according to the products used)
• No settlement and reinforced air tightness
• Freedom of thickness and phase shift (inertia)
• Insulation from the outside

POSSIBLE PRODUCTS   
Cellulose wadding, glass wool, rock wool, cotton, wood, hemp…

Spraying insulation

It is a solution quite similar to blowing. The difference resides in the projected material: the cellulose wadding benefits from a contribution of water playing the role of fixative (papier-mâché). The insulation is projected on the walls in vertical.

DEFINITION
It consists of applying cellulose wadding under pressure with a small amount of water. The water allows a perfect adhesion of the wadding on a vertical wall.

ADVANTAGES

• Total rupture of thermal bridges
• High density
• No settling
• Reinforced air tightness
• Freedom of thickness
• Phase shift (inertia)
• Insulation from the outside

POSSIBLE PRODUCTS   
Cellulose wadding.

Use the right PPE during insulation work.

In hard-to-reach areas, where heat is often intense (attics, etc.), the best way to protect yourself is to wear personal protective equipment that meets the requirements and standards.

The mask will allow the operator to limit considerably the inhalation of dusty particles.

It is also recommended to wear coveralls, gloves, and goggles.

Here is a selection of PPE adapted for your insulation and carpentry treatment sites.

Half-mask: order online 

Half-mask: a professional, durable half mask. It is ideal for the protection of operators during the handling of chemicals and dusts and during spray painting. To be used with P3 filters.

Dust coveralls: order online

Dust coveralls: Lightweight, ideal for dusty environments.

Spotlight covers:

Under CSTB certification, spotlight covers are mandatory when installing insulation in the attic.
