How Fibreglass Insulation Works and What It’s Made Of

21 November 2022

Do you need insulation in your house, and do you want additional information about fibreglass insulation and how it would function in your house?

Since the 1930s, fibreglass insulation has been utilised in the construction of residential buildings, and this practice continues to this day in contemporary building practises.

We are here to provide answers to some of the most commonly asked concerns regarding fibreglass insulation as part of D&D Insulation Services’ continued commitment to educating homeowners.

What Exactly Is Insulation Made Of Fibreglass?

Insulation is a substance that can be found in most homes, and one of those materials is fibreglass, made up of very tiny glass fibres. It is often utilised in producing two distinct kinds of insulation, namely batts and rolls, as well as loose-fill. Additionally, it is sold in the form of rigid boards and duct insulation.

According to the Department of Climate Change, Energy, the Environment and Water, manufacturers currently make medium- and high-density fibreglass batt insulation materials. Because of their higher density, these goods have a slightly higher R-Value than regular batts. The ceilings, floors, and walls of an unfinished structure are all suitable locations for installing fibreglass. It is installed in the spaces between the studs, the joists, and the beams.

In residential and commercial insulation projects, fibreglass is often used because of its ability to retard the transfer of heat and cold. Homeowners interested in economising a few bucks or doing the installation as a do-it-yourself job might consider fibreglass a viable alternative.

How the Insulation Made of Fiberglass Functions

Insulating a structure with fibreglass reduces the rate at which heat, cold, and sound travel through the building. According to the International Association of Certified Home Inspectors, the material accomplishes this by capturing pockets of air, which enables it to keep rooms warmer and cooler during the summer.

When attempting to make a house more comfortable, it might be helpful to restrict the quantity of air that flows into and out of the structure. It is essential to remember that fibreglass slows down the flow of air but does not entirely halt it.

What Exactly Is An R-Value?

The R-Value of insulating material is the capability of the substance’s resistance to the flow of heat. Simply put, this indicates that the insulating capacity of the material is greater the higher the R-Value of the material. Even while R-Value is something that one should be familiar with, it is not the most important factor to consider when it comes to insulation.

Your region’s climatic zone determines the insulation you need to have to meet the R-Value requirements that are mandated where you reside.

Material Components of Fibreglass Insulation

Insulation made of fibreglass is plastic woven with very fine glass fibres. Molten glass is spun into fibres while being covered with a liquid binder during the manufacturing process that creates fibreglass. After that, those bits are shattered into smaller, more manageable parts. The cooling glass fibres fall onto a moving conveyor belt, which piles up into a tangled mess as they go along.

The tangled fibreglass blanket is transported on the conveyor through the curing ovens. After that step, the batts are sliced to the desired dimensions in terms of length and breadth. In the event that the finished product is a loose-fill formulation, a binding agent will not be utilised.
