Fiberglass Batt Insulation and Fiberglass Loose Fill Insulation in Whitby

A good start - understanding the basics of home insulation

For homeowners who are seriously thinking about installing fiberglass batt insulation or fiberglass loose fill insulation in Whitby, it’s good to have an understanding of the basics. In the majority of cases, an insulation project is about reducing and potentially eliminating what the experts call “heat flow” or “heat transfer”. This is a dynamic where warm indoor air is leaking out of the house in winter, while warm outdoor air is coming into the house in summer. This isn’t any good for any home. And the result is inferior energy efficiency throughout the home, and utility costs (heating/ cooling) that are high.

Experienced insulation contractors look at a residential home as a “building envelope". In simple terms, homes are built with materials that have an affect on “heat flow”. That affect can be positive or negative, depending on the situation. What’s important with insulation is to effectively reduce (and hopefully eliminate) the areas of “heat transfer”. That’s why choosing the right insulation product is so critical. But regardless of product, a good installation will effectively address “heat flow”, and will serve to improve energy efficiencies throughout, while reducing energy consumption as well as energy bills.

Most homeowners know that there are a wide variety of insulation products on the market, and a wide variety of installation methods. But whatever the approach, the aims are the same. First - to effectively restrict the undesirable movement of air. Second - to prevent moisture from collecting. And third - to enhance R-Values where the insulation is being newly installed. It’s also important to have insulation installed by an expert, although many a homeowner might be tempted by a do-it-yourself approach. The fact is, an expert can assure good results with product and installation, especially for the long run.

Fiberglass batt insulation and fiberglass loose fill insulation

Residential homes in Canada and in the northern USA have routinely used the fiberglass products to insulate both attics and roofs. A professional install with these products provides very good R-Values and will generally improve the overall energy efficiency in the home. Both fiberglass batts and loose fill insulation have satisfactory lifespans and R-Values that will sustain over the long term.

Like most home insulation jobs, a professional installation is recommended with fibreless products. A professional installer understands the process of effectively installing the “thermal blanket”. With the loose fill product, for instance, it must be blown with consistency and uniformity. Similarly, the fiberglass batts must be installed strategically to ensure the performance of the “thermal blanket”.

Installing fiberglass products – the advantages

Fiberglass batts and fiberglass loose fill insulation are safe for residential use. Both of the products are asbestos free and air-quality tested/certified. Fiberglass is non-combustible and non-corrosive, and most of the brand name products incorporate recycled “glass”. In general, fiberglass products do not retain moisture in small amounts. An install will not settle measurably over time, and remains intact.

Under the right conditions, fiberglass products do not invite animals, rodents, or insects. And when properly installed, fiberglass doesn’t offer a favorable environment for mold to grow. Ventilation is essential with a fiberglass installation, in order to prevent the potential for deterioration. Either of the products allows for a very cost-effective project installation for most homeowner’s budgets.

Installing fiberglass products - the shortcomings

As a “stand-alone” insulation product, fiberglass does not do well in fully addressing the issues of moisture collection and air movement. This could be a big problem for attics or roofs, where air and moisture are a challenge. It should be discussed with a contractor to ensure the best possible results.

Restricting air movement is a problem with fiberglass because the product does not completely seal a space. This is problematic when installing in the attic, roof, or basement because creating an airtight space is important. Again, this is a good topic to discuss before any insulation work is started.

The biggest shortcoming of fiberglass products is wetness – a wet installation will lose integrity and R-Value slowly but surely. The fiberglass itself will eventually deteriorate, and will require total removal. This type of remediation will require removal of the insulation, repair of the space, and re-installation.

Wet fiberglass will be an inviting environment for mold to grow, and will potentially compromise the air in the home. Here again, the mold must be remediated, the insulation removed, and the insulation must be reinstalled. It’s work that requires a professional so that occupant health isn’t compromised.

Spray Polyurethane Foam – SPF - the very best on the market

As a result of the shortcomings of fiberglass products, an alternative has emerged - Spray Polyurethane Foam – an insulation option that can satisfy many applications. An SPF installation creates an actual insulation “envelope” – one that impedes air movement and prevents moisture from collecting.

In virtually every insulation project, leaking air (heat loss in winter, cool loss in summer) is an inherent problem. However, with SPF, the installed space is completely impervious and airtight. SPF creates a combination air barrier and moisture barrier, while delivering R-Values unmatched by other products.

The “hybrid” installation is a combination of insulation products

Overall, Spray Polyurethane Foam is acknowledged as the best insulating product available. One application delivers product performance that is hard to match by any comparable approach. That’s why professional installers are installing and recommending SPC for many a homeowner.

However, the SPF installation is not compatible with all project budgets and may be prohibitive for some. It’s because of this, that Great Northern Insulation developed the “hybrid” installation – a combination of Spray Polyurethane Foam and one of the fibreglass insulation products.

When employing the “hybrid” method, the outcomes are excellent, whether insulating the attic space, the roof cavity, or the basement. SPF provides the effective sealing and insulation, and the fibreglass product provides added insulation and additional cost-effectiveness for the project budget.

For performance, affordability, energy efficiency, and lower utility bills, the “hybrid” installation is the ultimate option for any homeowner.
