The Benefits of Blown Insulation
May 13, 2016
Blown insulation is a popular insulating product, widely used in residential applications. Usually available in two compositions (cellulose and fiberglass), the products deliver satisfactory results in the attic and roof cavity. Both compositions have comparable R-Values when installed, but the cellulose product has slightly higher R-Value. At the same time, cellulose has a tendency to settle, and this has a long-term effect on R-Value. Undoubtedly, there are upsides and downsides to each of the products - although a professional installation will assure the optimum in performance. Blown insulation products are manufactured to be fire resistant. With cellulose, the product is treated to impede fire from spreading. With fiberglass, the product itself is hard to ignite, mainly because of the glass fibre. Needless to say, the fire resistant element is particularly desirable for a space like the attic. As such, blown insulation is also recommended for "topping up" the existing insulation in the attic (provided the existing material is clean, dry, and uncontaminated). Clearly, this approach makes for a cost effective option when attic insulation requires enhancement.
Quite a quick installation job
Installing blown insulation is fast, when compared to other methods. With a professional install, the "thermal blanket" that is blown throughout will deliver satisfactory levels of R-Value.
Very good energy efficiencies
Blown insulation provides satisfactory energy efficiency where installed. Coverage is complete and comprehensive, filling many of cracks and crevices in the attic (although not 100% airtight).
Sound and noise dampening
With a good install, blown insulation can prevent noise from migrating from space to space. This could be of benefit to those who use the attic space or adjacent areas for work or recreation.
Energy savings every season
A properly insulated attic is well worth the project cost. Doing it right will stop heating and air conditioning from leaking, and will save on energy consumption and costs throughout the year.
Containing recycled content
Cellulose blown insulation is composed of recycled, shredded newsprint. The fiberglass product is made of glass fibres, much of which is recycled glass. For some, this is an important feature.
Complete, in-depth coverage
Professionally installed, blown insulation provides good coverage in an attic, blanketing all of the wooden crossbeams; the plumbing pipes; the electrical wiring; and even the television cables.
Overall longer-term benefits
In a typical residential install, blown insulation creates enhanced energy efficiency throughout the building - improved heating and cooling cycles, as well as enhanced HVAC performance. All things considered, blown insulation is a cost-effective application, with satisfactory insulation value, and an affordable budget commitment. However, these are products that require expertise during the installation process. It means that a professional approach is recommended - this will ensure peak performance for the product, and an installation that will deliver results for years to come. Good contractors do the job right - they follow the building code - they maintain schedules - and they stay on budget. And while the DIY approach might be inviting for some homeowners, the finished results of a professional job are far more preferable.
