Fibreglass Loose Fill Insulation and Fibreglass Batt Insulation in Huntsville
Understanding the essentials of residential home insulation
For residential homeowners who are contemplating fibreglass loose fill insulation or fibreglass batt insulation in Huntsville, it’s important to understand the essentials. The principle behind insulation is to eliminate what professional installers call “heat transfer”. It happens in winter when heated air from inside the house flows out of the house. And it happens in summer when outside heat flows into the house. Both of these dynamics are undesirable – they make for a home that is energy inefficient – they cause utility bills to be higher than need be – and the extra energy costs are borne by the homeowner.
Professionals look at a residential home as a “building envelope". This “envelope” contains a variety of building materials affecting “heat transfer” throughout the home. In some cases, the effect is positive and in some cases the effect is negative. With home insulation, the general idea is to diminish and even eliminate the negative effects. And that’s why it’s so important to install home insulation that will address “heat transfer” effectively. The result: energy efficiency in the home is measurably improved; overly high utility bills are seriously reduced; and indoor heating and cooling cycles are balanced.
Most residential homeowners are aware of the many insulation products available today. However, regardless of the product, the reasons for insulating are common - to stop unwanted air movement; to stop unwanted moisture accumulation; and to measurably increase R-Value. These are fundamental to any insulation project. But probably most important when insulating the home is to work together with an expert. Although it’s true that dollar savings can be realized by taking on a do-it-yourself (DIY) approach, it’s the expert installer with experience and expertise that will achieve the better results.
Fibreglass insulation products - a popular insulating option
For residential homeowners in most of Canada and throughout the northern United States, fibreglass insulation products (loose fill and batts) have become quite popular over the years. They are often used in attics and roof cavities, and provide R-Values that are satisfactory. When properly installed, fibreglass insulation products will improve energy efficiency throughout the home, and will noticeably reduce energy consumption from one season to the next. The product’s lifespan is also satisfactory.
Like so many home improvement projects, insulating the home requires some expertise. Professional insulation contractors understand the nuances of product and installation - they know how to create a “thermal blanket” that is effective for the space. With the fibreglass batts, for instance, they require strategic installation for peak performance. Similarly, the loose fill product requires an installation that will be consistent and uniform – it’s the only way that the “thermal blanket” will be effective.
The fibreglass insulation products have benefits
With a professional install, and following the product specifications, fibreglass insulation products are safe. These products are totally free of asbestos and have been air-quality tested. The final installation is non-combustible and non-corrosive. For the most part, fibreglass insulation products will contain quantities of recycled “glass”. The final installation doesn’t retain moisture (small quantities) and will not settle down measurably over the years.
Fibreglass products are treated to resist rodents, animals, and insects. With a professional installation, the finished space is does not provides a welcoming environment for mold to grow or develop. And when the insulated space is properly ventilated, there should be no potential for fibreglass products to deteriorate. Residential homeowners contemplating fibreglass insulation in Huntsville will find this application to be a cost-effective project.
Fibreglass insulation products have some disadvantages
Insulation professionals assert that fibreglass products do not fully address issues like air movement and moisture accumulation. This is considered a disadvantage when the attic is being insulated mainly because air and moisture issues can compromise the overall project.
An additional issue in the attic is air leakage, and here again, fibreglass insulation has some problems. On it’s own, fibreglass does not seal, even with a professional install. This is problematic since sealing up a space is vital for any insulation product to perform at peak.
The most serious issue with fibreglass insulation products is wetness. When fibreglass is wet, it loses integrity and therefore loses R-Value. Unresolved, wet fibreglass deteriorates to a degree where the installation requires remediation – removal/repair/reinstallation.
Probably the worst-case situation with wet fibreglass is mold. And with a mold infestation, practically the only remedy is professional remediation. This is work for an experienced mold removal specialist, followed by a professional re-install of the original insulation.
Spray Polyurethane Foam - the go-to product for the experts
Due to the disadvantages of fibreglass insulation products, Spray Polyurethane Foam has now become a viable alternative for many experts. With a single application of the SPF product, an insulating “blanket” is created to stop unwanted air movement and unwanted moisture accumulation.
Air leakage is also a problem when insulating – a problem that must be fully addressed. With Spray Polyurethane Foam, a finished install is completely sealed. The environment is airtight, and prevents indoor heat from escaping in winter, and outdoor heat from coming in during summer time.
The “hybrid” installation – combining fibreglass and SPF
As the very best product on the market, Spray Polyurethane Foam is being highly recommended by the professionals for attics, basements, and even garages. However, SPF is not suitable for every project budget – this is a premium product with a premium cost. And because of the cost, a more cost effective installation has been developed – the so-called “hybrid” installation.
The “hybrid” installation simply combines a fibreglass product with the SPF product. It’s an install that benefits from the best of both products. The SPF application provides excellent sealing and insulation, while the fibreglass product provides additional R-Value and a cost-effectiveness that results in better dollar value for the insulation project as a whole.
For those homeowners contemplating fibreglass loose fill insulation or fibreglass batt insulation in Huntsville, this combination of SPF and fibreglass may well be the best insulation project of all.
