If you’re looking for blown in insulation in Markham, or in the communities north of the GTA, then Great Northern Insulation is a contractor worth considering. Our approach is to do a job the right way, the first time - allowing for a workable, cost-effective solution that meets a customer’s needs and accommodates their budget. Our people do their best to make sure that the insulation challenge in question is addressed and that long-term benefits are achieved.
For blown in products, the two most common in the market are cellulose and fiberglass. Both are factory-designed for use in roofing, attics and wall cavities. And in the marketplace, each brand manufacturer supports, promotes and markets their product. For insulation value, both cellulose and fiberglass have comparable worth, but statistics show that cellulose has slightly better R-values than fibreglass - this is a comparison made based on per-inch coverage. We also know that over the long term, cellulose settles, and this has an affect on relative insulation values. For the fiberglass product, manufacturers assert that the product does not settle, so there is no loss of insulating value. To be sure, whatever the final choice of product, each has its own set of qualities when reacting and responding to the weather.
Cellulose and fiberglass insulation are specifically manufactured to be fire resistant. Cellulose is treated with a fire retardant that is designed to keep a fire from spreading. The fiberglass product, composed primarily of “glass”, is a difficult combination to ignite, and therefore provides a very high level of fire resistance. In terms of product composition, cellulose is comprised of shredded newsprint (recycled) and is treated with anti-fungal chemicals to resist both insects and mould. The recycled paper is fiberized - meaning its mechanically separated into fibres, giving it a unique insulating capacity. Fiberglass blown insulation is different - it’s made primarily of glass fibres, a proprietary fabrication process that makes for a product with distinct insulating properties and features. When it comes to application and installation, both the cellulose and fiberglass products are similarly blown into a cavity, using specially designed equipment that can distribute the insulation in a uniform manner. It’s a relatively straightforward installation, suing a hose apparatus that blows the insulation into a cavity, and assures even coverage everywhere - even the smallest cracks and crevices.
Great Northern Insulation specializes in blown in insulation, so when you’re looking for blown in insulation in Markham, GNI is a contractor worth considering. We sell and install only the highest quality products, and we always pass the manufacturer’s warrantee through to our customers. We also guarantee our installations, and ensure full customer satisfaction on every project. In short, we stand behind our products and our installations. Our people are always informing customers about which insulation product they should be installing - and the reasons behind the advice. We never engage in selling or up selling an insulation project that a customer does not need or want – indeed, we are not averse to telling a customer that an insulation install is not even required.
As a general rule, blown insulation is a straightforward install compared to many of the other insulation options. Because of the equipment we use and because of the product’s composition, blown in insulation allows for ease of application, with less potential for problems. As it is, we work with our customers from the beginning of a job to the end, making sure that each customer is completely satisfied. We begin the process by choosing the correct product for the job in question; we continue by arranging an installation that accommodates the customer’s lifestyle and schedule, and we work around it; finally, our installations adhere fully to construction standards and building codes.
At Great Northern Insulation, our expert installers understand that the performance and integrity of the installed product is directly dependent on the quality of their installation. And that’s precisely why we want every job to be done right, the first time. We make sure to use the tools and equipment that are appropriate for the project, and we make sure to pay attention to the safety of the occupants and our installation teams. And when we say doing it right the first time, we also mean doing the job in total, and quite often doing it right could include additional work. Its just that the proposed insulation job may require more than insulation - air sealing or draft proofing may be required; there may be a need for a vapour barrier prior to blowing in the insulation; or, there may well be a need for new vents or exhausts to ensure optimum air circulation. For GNI, this added scope of work is what constitutes a “total” job, and it’s absolutely required when delivering a final install that presents the full integrity of the product we are installing.
The benefits and advantages of blown insulation are straightforward, making it a viable and affordable option for many customers. The composition of the insulation itself is advantageous because virtually no cavity remains unfilled after the insulation is blown in – in fact; there are no cracks or crevices that remain without insulation. Safe to say, that many other insulation products do not provide this kind of coverage. Not only that, the blown insulation provides complete coverage around support beams, electrical wiring, plumbing and piping. Professionals in the industry consider this a “true insulated building envelope”, and when we’re done, the finished insulation enhances the overall performance of the indoor environment.
More recently, our customers have been asking for eco-friendly products. Sometimes they ask just to be more eco-conscious; sometimes there are personal health issues; sometimes they are concerned about sustainability; and many times they will have concerns about the composition of a product. The cellulose product is by definition recycled – it contains very high amounts of recycled paper. The fiberglass product, because it’s manufactured with certain amounts of recycled glass, is also eco-friendly. But today, customers can rest assured that manufacturers are sensitive to the eco-consumer, doing whatever they can do to accommodate those needs.
