Fibreglass Loose Fill Insulation and Fibreglass Batt Insulation in Mississauga

Understanding Insulation

For the typical homeowner to better understand insulation, it’s also a matter of understanding heat transfer (sometimes called heat flow). In most cases, heat transfer is unwelcome – it means that the indoor heat is escaping in winter and the outdoor heat is creeping in during the summer. Unwanted heat transfer causes energy inefficiency and energy loss – it makes for costlier utility bills. Every home is a "building envelope", made of materials that positively and/or negatively affect heat transfer – and the objective with insulation is to create energy efficiency.

For homeowners who are considering fibreglass loose fill insulation or fibreglass batt insulation in Mississauga, the aim of insulating is the same: to eliminate unwanted heat transfer. By doing this, energy is conserved and seasonal energy costs are reduced. With insulation, the idea is to prevent air movement, inhibit moisture accumulation, and enhance overall R-Value. Regardless of the insulation product chosen, or the installation method employed, the key is to maximize the performance of the insulation so that the homeowner can realize positive outcomes.

Fibreglass Insulation

Fibreglass insulation is well known to most homeowners. Fibreglass batt insulation has been used for years in attics and inside walls, while fibreglass loose fill insulation has been used as a blown-in product for the same types of spaces. Both products offer good resistance (measured as R-Value) and when professionally installed will contribute to saving energy. Overall lifespan for fibreglass insulation provides good value, and R-Value is well maintained over the long term. For the professional installer, both of these products are easy to transport, manage, and install.

As for installation, both of the fibreglass products require some expertise. Fibreglass batts must be installed uniformly and strategically, while loose-fill insulation must be dispersed properly for even density. Both of these products are good for “topping up” any existing insulation, as long as the existing insulation is not water-damaged or deteriorated. When professionally installed, both of these products will provide a satisfactory “thermal blanket” which will reduce air movement. A good application (of either product) will result in effective insulation throughout the seasons.

The Benefits of Fibreglass

Fibreglass batt insulation and fibreglass loose fill insulation do not retain small amounts of water. Short of being soaked, small amounts of water will evaporate within a short period of time. When professionally installed, these products don’t settle significantly, and will maintain satisfactory insulating values for years. Both products are quite safe to install in any interior space. It’s also worth noting that fibreglass is odor-free, non-combustible, and non-corrosive. In fact, most of the quality brands are air-quality certified. The fibreglass products contain sizable recycled content.

Fibreglass insulation products do not contain chemicals that would promote mildew or mold, and will not provide the nourishment to attract insects or rodents. Both fibreglass batt insulation and fibreglass loose fill insulation contain no asbestos, and when properly installed do not pose a risk of rotting or decay. Both of these product options are affordable for most homeowner budgets, and will provide a cost-effective insulation approach for many years to come. For best results and long-term performance, a professional installation is highly recommended.

The Drawbacks of Fibreglass

The drawbacks of fibreglass insulation are relative to the product’s overall performance level. This is particularly relevant when it comes to moisture control and air movement. These problem areas should be weighed and addressed prior to installation.

Because of the product’s composition, fibreglass batts and fibreglass loose-fill will allow some air to pass. Because of this, air leaks are not always totally sealed after the insulation is installed – it means that this product does not provide 100% insulation.

When wet, the fibreglass products (both batts and loose-fill) can be vulnerable. This could well compromise the R-Value. And depending on the wetness, there is potential for deterioration and possible contamination – it means that removal is necessary.

Unfortunately, with moisture and wetness issues, there is potential for mold growth. Without action, mold can contribute to poor air quality circulating around the house. Without doubt, this type of situation will require removal of the insulation.

Spray Foam Insulation

When addressing the failings of fibreglass insulation, a good many contractors are opting for spray foam insulation as an alternative product. Spray foam insulation adheres to practically any surface, including uneven or irregular surfaces. With a professional application, spray foam will create a seamless air barrier, and will overcome the problems common to the fibreglass products. Where the fibreglass products don’t fully seal holes and gaps, spray foam insulation seals it all.

When insulating a space, the biggest problem is air leakage. In the winter, warm indoor air can escape, and in the summer hot air can intrude. This makes for increased energy costs. But with spray foam insulation, air leakage is eradicated. In attics and in basements, spray foam creates an airtight environment, resulting in better energy efficiency, less energy consumption, and reduced utility bills. A spray foam application will also last a lifetime, without any need to replace.

The Hybrid Installation

Throughout the industry, spray foam has proven to be a superior insulating product. With one application, an airtight envelope is created - it prevents air movement and moisture collection, while delivering superior R-Values. A spray foam application will deliver more benefits than any comparable product, and the outcomes are excellent, both short term and long-term. This is a premium priced product, so for more restrictive budgets a “hybrid” installation is recommended.

The experts at Great Northern Insulation often recommend the “hybrid” install when spray foam does not fit a project budget. This install combines one of the fibreglass products with the spray foam product into one application. And with both products in one application, excellent results area achieved within a cost-effective budget. Best of all, the “payback” period makes the overall investment worthwhile. For many homeowners in Mississauga, the “hybrid option is the ideal.

Whatever the choice - fibreglass batt insulation, fibreglass loose fill insulation, or spray foam – a professional install will ensure the best possible outcomes.
