An issue with which many homeowners in Toronto are confronted is whether or not they should remove the old insulation. The fact is that prior to embarking on a renovation project, it is a good idea to remove the old barrier and replace it with a new one. Building material deteriorates with time, thus becoming a less viable option. The old layer of protection can create a number of issues around your home. Not only will it not provide you the results that you were expecting, but it can also be filled with excrement and mildew. Insulation removal makes sense and it is the only way to ensure that your family enjoys a clean and healthy environment. While this practice is not very popular, you should make insulation removal your priority.
Elaborating upon the necessity of removing old insulation
Whether you are planning to embark on a renovation project or you are simply interested in increasing the R-value of your home, it is important not to neglect removing the old layer of protection, especially if your home was built in the 1960s. Undoubtedly, insulation does not last for a life time, which is the reason why you should make efforts to replace yours. Even if materials are able to hold their aspect for several years, they ultimately lose their strength. When the layer of protection becomes less viable, it can either become damp or infested with rodents and other pests. This means that you should absolutely not add another layer on top of the existing one. On the contrary, you should eliminate it and equip your home with a proper barrier against moisture and cold air.
Cases in which you should replace your home insulation
According to experts, not all situations require the complete replacement of the layer of protection. Unless the situation is serious, you can simply add another seal. For instance, if the covering is slightly compressed, a complete replacement is not really necessary. On the other hand, if the material is not strong enough, it is severely damaged or, worse, it was not installed properly, the best course of action is to extract it. You may think that it is performing a good job, but the reality is that the seal will not help your home stay warm. What you have to keep in mind is that the prices for heating are constantly rising, which is reason enough to invest in a cost-saving solution.
Typical signs that you need to replace your home insulation
Unless you call a Toronto insulation professional to come inspect your home, you cannot know for sure if your home insulation is a faulty one. Or is there? The fact is that there are some classic signs that indicate there is something wrong with the seal. If you happen to notice the following clues, you should take measures immediately:
- Fluctuating temperatures – the temperature in your home should be unchanging, so if you notice a significant difference between the temperature upstairs and that downstairs, you should know that this is due to the fact that air leaks in your attic. Normally, you should have the exact same temperature in all the rooms. Before blaming the seals, see if there is a window left open by mistake.
- Increased energy bills – insufficient protection can account for high monthly energy bills. If the energy bills suddenly go up, this is a clear sign that the old barrier is not working anymore. Outdoor air manages to penetrate the home through the attic or crawl spaces and causes the temperature to change.
- Water leakage – the layer of protection should not be damp or moist. Should this be the case, you can be sure that the insulating material accommodates mold spores. It does not really matter if the material dries, the spores still infiltrate the air and cause health issues. Fiberglass in particular harbors mold, quickly becoming a useless solution.
- Unappealing insulation – if the open ceiling reveals ugly material that creates a bad impression, you should consider evacuating it. The likelihood is that the material has been vulnerable to dusts, rodents, wind, and cold and warm temperatures. Not only do they not do their job of trapping air, but they are dangerous to your
Choosing new home insulation
Now that it is clear that it is necessary to eliminate the old protective building material and install a new one, it is important to choose the right one. The preferred choice in Toronto is spray foam insulation. Spray foam is capable of increasing the strength of your walls, not to mention that it has a high R-value. This basically means that is has a high thermal resistance. With spray foam, air infiltration or heat loss will not be an issue. Of course, there are other options you should take into consideration, including cellulose and blown fiber. Your decision will depend largely on where you need to add seals and the recommended R-value for that particular area.
Removing old insulation
Leaving the building material will not do you any good. When you are sure that you want to install new building material, you should get your hands on a knife, a pair of gloves, a dustpan and brush set, a respirator and a protective eyewear. The simplest way to evacuate the old building material is to pull it from the decayed area, even though the process may take you some time. Do not forget to put on your safety equipment. As mentioned before, the barrier could be home to mold and excrements, reason why you should safeguard your health. When you are finished, make sure to vacuum the remaining pieces and to properly dispose of them using garbage bags. Of course, the right thing to do would be to hire insulation removal specialists who are more equipped to deal with the problem than you. There are many reasons why you should leave the job to professionals, including the fact that they have encountered a number of scenarios.
