CELLULOSE V/S FIBERGLASS INSULATION. WHAT’S BEST FOR YOU?

Fact Check: About 50% to 70% of the energy is consumed for heating and cooling in average homes.

Insulation is one of the best ways to reduce and control your energy bills from peaking. The even-more-important-factor is its function of maintaining and providing an even thermal condition in your home or commercial structure. As compared to older homes, newer homes cost you lesser energy bills. Basically, insulated homes perform well and increase their comfort level. There are different types of insulation with their respective specifications, pros and cons. This article is going to discuss on Cellulose Insulations vs Fiberglass Insulation, since it’s most commonly used and have higher demands in the building industry.

CELLULOSE VS FIBERGLASS INSULATION

Both cellulose and fiberglass are two most commonly used insulations. The two insulations have successfully improved energy efficiency in homes over the years. With varying locations and building code requirements, fiberglass and cellulose insulation can be beneficial for homeowners, builders and remodelers.

There are existing actors that distinguish these insulations from each other. Although fiberglass precedes and has been frequently used, cellulose insulation has been gaining more popularity in recent times.

What is the difference between Cellulose and Fiberglass?

As homeowners, it is necessary to know about the insulation being used in your homes for its enhancement in terms of safety and comfort. Before knowing which insulation is better than the other and why, understand what these insulations are made of and how they are used.

What is Cellulose insulation?

Cellulose Insulation also called as the greenest of the green is 85% recycled paper, 25% treated with non-toxic borate compounds that prevent mold growth or insects and fire and is high in thermal efficiency.

Cellulose is a wet-spray or loose-fill form of home insulation which is used in enclosed existing walls or open new walls and attic floors. It is ‘green’ which means greater per cent of its composition is recycled and environment-friendly. According to the claims of Cellulose Insulation Manufacturers Association Canada (CIMAC), insulating homes with cellulose recycles newspapers compared to an individual’s consumption in 40 years. Often made using paper fibers, newsprint, cardboard are the primary ingredients. Cellulose Insulation is considered as a natural thermal insulation that increases the efficiency of structures it is used in.

What is Fiberglass Insulation?

30% to 50% of the raw material used in the manufacturing of fiberglass comprises of the recycled window, bottle or automotive glass.

Since 1938, fiberglass has been preeminent insulation material for many homes and other commercial buildings. Fiberglass insulation is an amalgamation of limestone, soda ash, silica sand, and recycled glass cullet. In simple words, it is made of glass fibers. Micro-thin glass fibers spun into batts make structures more energy-efficient and reduce utility bills making the structure more comfortable for the occupant. Newly manufactured fiberglass is higher in R-value as compared to the older ones. Fiberglass insulation can be installed in unfinished walls, ceilings and floors and fitted between joints, beams and studs. Fiberglass comes in different types- batts, rolls and blown-in insulation.

Batts are usually placed between frames and used in walls, floors, attics and ceiling. Rolls are fitted between joists and studs. Blown-in fiberglass is used for wall cavities and attics.

What are the benefits of Fiberglass and Cellulose Insulation?

Cellulose InsulationFiberglass InsulationIt is ‘green’ or eco-friendly. Lightweight and easily portable. Fills cavities and creates an energy-efficient building. High thermal performance and available in different types.Retains its R-value even in extreme cold conditions. Easy for DIY installation and cost-effectiveHealth-friendly, fireproof, resists mold.Fireproof No degradation concerns.Prevents mold or mildew growth.SoundproofSoundproofRepels insects and crittersSimilar to animal bedding (higher risk of animal infestation)

Is Cellulose Better Than Fiberglass?

Installation

The light weight and flexibility of fiberglass make the installation easy. Along with that, transportation and application become simple and easier too. While cellulose is 18% heavier and requires adequate installation knowledge or improper installation leads to the reduction and degradation of thermal protection. Fiberglass is less dusty and easy to handle. Cellulose is comparatively dustier due to its recycled component and requires a minimum of 36 hours to dry. With its ability of high compressibility and lesser chances of degrading the effectiveness of R-value, fiberglass can be manufactured into greater amounts. Fiberglass batts are easier for installation, especially for DIYers. But it needs to be blown-in with a blowing machine which is slightly more difficult and may require professional help. Cellulose insulation is more commonly installed by professionals and is always blown-in.
