How to properly and how insulate the attic floor

The issue of building insulation is now more acute than ever.  Most people start with wall insulation, but they end there, however, as you know, warm air tends to rise and leave through the roof, so attic floor insulation plays an important role.  As with all construction work, insulation should be carried out with high quality.  It is important to know how to insulate the attic insulation mississauga floor to get the maximum benefit.

The choice of insulation

When choosing a heater for an attic floor, it is important to take into account its heat-shielding properties, strength, and resistance to external factors.  The type of flooring will also play a role: concrete and wooden floors have their characteristics.

Mineral wool

Most often, attic floor insulation is carried out with the help of mineral wool.  It is important to know what are its features and why is this heater so popular

Benefits of mineral wool:

High thermal insulation: for example, to insulate an attic floor with mineral wool, the layer thickness is 3.5 times less than when using expanded clay.

Ease of material installation: This insulation is not difficult to work even for those who are engaged in insulation for the first time.

Fire safety: Mineral wool is not easily flammable, therefore, in the event of a fire, it does not serve as a fast carrier of fire, which, for example, cannot be said about polystyrene foam.

Long operating period: if you properly lay the mineral wool, it will not roll down and will not create cold bridges.

Affordable price:  It is thanks to all these advantages that attic floor insulation with mineral wool is a widely used way to save heat in a room.

However, this heater also has disadvantages.  In particular, due to its ability to absorb moisture, the mineral wool insulation layer may no longer provide the same thermal insulation as before.  Also, when insulating the attic floor with mineral wool, it is important to observe safety precautions.  Mineral wool fibres can irritate when it comes into contact with the skin, so you should work with them in tight clothes, goggles, a respirator and, of course, gloves.

After analyzing all the advantages and disadvantages of different heaters, many conclude that mineral wool is an ideal option because it has high thermal insulation properties, is fireproof, easy to install, and also has an affordable price.  As for its disadvantages, hygroscopicity can be compensated by installing a vapour barrier and waterproofing, and inconvenience when laying mineral wool – by observing safety rules.
