No. The International Agency for Cancer Research recently removed fiberglass from its list of possible carcinogens, based on its review of more than 15 years of research. Research conducted over the past 70 years shows that exposure levels are low, and that, even if inhaled into the lung, most fibers disappear quickly with no adverse health effects.
Fiberglass serves a number of useful purposes, but the most important application of wool-type fiberglass is as insulation used primarily to control temperature and sound in homes, commercial buildings and industrial operations.
Although there are various types of insulation that helps to muffle sound better than others, we cannot guarantee a 100% soundproof. Results are often better at the building stage than in a retrofit.
Ice dams are the build up of ice, generally along the roofs edge.They are the result of snow melting on the roof and freezing before it has the chance to run off. With a number of such cycles, the dam of ice builds up as more and more water freezes and pools behind the dam. As the ice dam spreads up the roof, water can eventually work its way under the shingles and enter the attic. Once the water enters the attic, it can damage the roof, ceilings, walls and contents of your home. If the attic insulation becomes wet, the value of the insulation is lost and can lead to a rise in temperature of the attic which can accelerate the growth of the ice dams. Look for the formation of icicles, which is a sure sign of ice damming.
Generally, Fiberglass insulation has an R-value of about 2.7 per inch of thickness, compared to Cellulose R-value of 3.4 blown in or 3.8 settled per inch. Overall, cellulose is a denser product. So, cellulose is considered to have an overall better R-value than fiberglass insulation.
Signs of insulation problems may be: high heating costs, walls feel cold to the touch, mould on walls, drafty windows, cold floors, ice damming, cold rooms.
Since the R-values are cumulative, there is no need to remove what you already have as long as the existing insulation is not contaminated. Instead we just blow a new layer of insulation over the existing one, adding up the resistance values together.
The basement or crawl spaces of your house, all outside walls need to be insulated with polyurethane foam insulation. This type of insulation provides a total seal to keep out the cold air that is cooling down your floors.
Caution while comparing quotes. Make sure you are comparing apples to apples. Different R-values, or products could be the difference especially for spray foam. Pricing on Spray foam will be greatly affected by the type of foam you’ve been quoted. For example: A 2lb medium density product such will be a higher price than a 1/2 lb low density product. Insultech can provide an estimate on both products. We also include everything in our estimates to give you a 100% complete job. Extras will only be added on at your request, other than that the estimated price is the end price.
Yes! Except during the application. We recommend that no one is present during the application and should give 24 hours before entering the work area. Polyurethane foam has been used on many different applications for many years and has been tested extensively for safety. There are no emissions or any harmful substances related to the foam under normal conditions.
