Blown In Insulation
March 19, 2015
Blown in insulation is one of many products available on the market today. For the most part, there are two versions - cellulose and fiberglass. Both products are designed for use primarily in the attic and throughout the roof cavity. Once installed, cellulose and fiberglass have similar R-Values (per inch installed), but according to industry statistics, the cellulose blown in insulation has a slightly better R-value than the fibreglass product. On the other hand, cellulose has an inclination to settle over the long term, and this may well have an affect on R-Value. Although similar, each product has its own singular features. However, both products are designed to be fire resistant - the cellulose product is specially treated to retard the spread of fire, while the fiberglass product is difficult to ignite, simply because of its glass fibre content. Clearly, blown in insulation is a desirable product for the attic. In addition, many contractors will suggest "topping up" existing attic insulation with the blown in product, and as long as the existing material is clean and dry, it's a cost-effective solution that delivers added R-Value. In terms of composition, cellulose is made of 100% recycled, shredded newsprint. It is treated to be anti-fungal, and is "fiberized" (separated into fibres) to give it a fluffy composition. The fiberglass product is manufactured from fine glass fibres - a proprietary process designed to give the product its insulating potential. As for the application, cellulose and fiberglass are both blown into a space, hence the name. Special equipment is used to spread the insulation uniformly, and assure complete coverage - even into the smallest, hard-to-reach spaces. For blown in insulation to deliver peak performance, a proper install is essential, and it's preferable to have experience and expertise. A good contractor will do the job right, the first time: suggesting the right product for the job; abiding by construction standards and building codes; and taking into consideration the customer's schedule and budget. Indeed, there may even be extra prep-work that is required - like air sealing or draft proofing; or installing a vapour barrier; or creating additional air vents. It's this kind of comprehensive approach that delivers the best results. There are many project advantages with blown in insulation. Both cellulose and fiberglass provide excellent coverage, filling practically every opening, gap, and crack. Unlike other insulators, blown in insulation blankets a given space completely: wooden crossbeams; electrical wiring; plumbing and pipes; even television cables. Professionals refer to this kind of coverage as a "true insulated building envelope". And for the customer, the benefits are numerous - heating/cooling is better regulated; sound and noise is dampened; and HVAC performance is enhanced. Overall, blown in insulation is a straightforward application that offers excellent insulation value, and affordability for most any budget. As such, a reliable insulation contractor can provide a full service approach under one roof - they will have extensive product knowledge; provide dependable product availability; and will deliver the technical expertise that ensures peak product performance and an installation that is guaranteed for the long term.
