Fibreglass Loose Fill Insulation and Fibreglass Batt Insulation in Middlesex County

A Better Understanding of Home Insulation

For the average homeowner, regardless of house type, understanding home insulation will make for better decision making down the line. Essentially, insulation is about preventing undesirable “heat transfer” or what experts call “heat flow”. In winter, heat flow is indoor heat that’s escaping out. In summer, heat flow is outdoor heat that’s creeping in. Both dynamics are inefficient, and both create energy loss and high utility bills. In short, insulation is designed to stop “heat flow”.

In Middlesex County, and throughout the neighbouring communities of London, there are many insulation options for homeowners – everything from fibreglass loose fill insulation, to fibreglass batt insulation, to spray foam insulation. With every option, the objective is basically the same: to reduce heat flow; to reduce energy usage; and to reduce energy costs. With good insulation, this is achieved through enhancing R-Values, blocking air movement, and diminishing air moisture.

Choosing From Fibreglass Insulation Products

Over the years, fibreglass insulation has become a popular residential application. Fibreglass batt insulation is quite common in attic applications, basements, and exterior walls. As for fibreglass loose fill insulation, this product is blown into large, expansive spaces - like the attic and roof, and sometimes wall cavities. Both products are equally satisfactory in terms of R-Value, and both will enhance energy efficiency. Product lifespan for fibreglass is good, and performance is sustained.

As for installation, both of the fibreglass insulation products require expertise. The “batts” must be strategically installed to ensure peak performance. The “loose fill” product, on the other hand, must be blown into a given space to ensure a perfectly uniform density. Both fibreglass products can be used effectively to “top up” existing insulation. When professionally installed, fibreglass insulation creates an efficient “thermal blanket” that will reduce air movement, while insulating.

Fibreglass Insulation Does Have Benefits

Neither the fibreglass batt insulation nor the fibreglass loose fill insulation will retain water, and usually, small amounts evaporate. Neither product settles dramatically, so that insulation values are maintained for the long run. Completely safe for indoor application, both fibreglass products are odor-free, non-corrosive, and non-combustible. Finally, fibreglass insulation does not provide a welcome environment for mold, mildew or fungus.

When professionally installed in a dry, ventilated space, the insulation should not deteriorate or decay over time. As well, the installed materials are not a comfortable environment for insects, rodents or vermin. An affordable insulation option, fibreglass batts and/or loose fill can provide a cost-effective approach for insulating the home. Long-term performance is satisfactory, and the savings on heating and cooling make it worthwhile.

Unfortunately, Some Downsides to Fibreglass Insulation

The main downsides of fibreglass insulation are related to performance. Here, there are problems when effectively limiting air movement and air moisture. For homeowners considering fibreglass insulation, these problem areas should be addressed.

Because of fabrication, fibreglass insulation products do allow air to move through the installed insulation. This is not desirable with any insulation, especially in the attic or roof cavity. The problem is that fibreglass doesn’t seal a space properly.

If fibreglass insulation becomes overly wet, there can be problems. R-Value will be compromised, and insulation performance will therefore suffer. Depending on the amount of wetness, there is a chance for contamination, making removal necessary.

With fibreglass insulation, very high moisture levels (without proper ventilation) could promote mold growth. Unattended, mold can create air quality issues throughout the entire home. In a case like this, insulation removal will be necessary.

An Alternative Insulation Option - Spray Foam

In addressing the downsides of fibreglass insulation, industry professionals often suggest spray foam as an option. Unlike fibreglass, spray foam creates an airtight barrier that effectively seals a space - including all openings, holes, gaps, and cracks. For professionals, this solves a big issue when insulating a space – that is, preventing air leakage.

Uncontrolled air leakage allows for “heat flow” in both winter and summer, and largely results in poor energy efficiency. With spray foam, air leakage is essentially eradicated. Professionally installed, spray foam insulation allows for a completely airtight space that prevents “heat flow”, enhances energy efficiency, and reduces energy use.

The Best of Alternatives - a Hybrid Installation

Spray foam insulation is a superior installation compared to other products. A professional install delivers superior R-Values, much reduced air movement, and much reduced moisture collection.  Because it delivers more benefits than anything comparable, spray foam has become the product of choice for industry professionals.

In some situations, however, spray foam insulation does not suit a homeowner’s budget. Here, the experts at Great Northern Insulation can offer the best of alternatives - a “hybrid” installation.  This is an application where fibreglass insulation is installed alongside spray foam insulation - it’s an extremely cost effective approach.

For homeowners in Middlesex County, the “hybrid” install could be the best choice for achieving home energy efficiency. Whatever the final choice, and whatever the type of house, it’s important to contract a professional - a reputable contractor who can offer the best return-on-investment, and an install that delivers performance.
