Roof insulation is best known for improving the energy efficiency of a roof, but this isn't the only reason your roof needs to be insulated; there are other reasons for it. For example, insulation also prevents the roof from heating up and experiencing accelerated wear and tear.
There are various types of roof insulation, but blown in cellulose insulation is one of the best. Here are some of the advantages you will enjoy if you decide to use this type of insulation:
It Is Efficient
One of the best things about blown-up insulation is its level of energy efficiency. This is possible because the insulation is comprised of cellulose fibers that can be blown up into even the tiniest of places. It can also be installed to the exact desired thickness.
At the same time, the fluffy mounds of insulation will trap air between them, which prevents heat transfer. Both of these mean that the insulation will make an airtight lawyer in your attic, which is exactly what you need for an energy efficient insulation.
It Is Good for Noise Insulation
If you want an insulation material that is good both for energy efficiency and noise insulation, then blown-in cellulose insulations is a good way to go. This is what you should think of if you have a noisy roof or don't want to hear the pounding noises of rainfall on your metal roof. Of course, this may not be your primary reason for insulating the attic, but most people will find it a great added advantage.
It Reduces the Risk of Fire Damage
Fire needs to things to thrive and spread – fuel and air. Packing an airtight insulation material on your roof will starve any fire that breaks out of the oxygen it needs to burn. For example, if embers or flames of fire from a nearby bushfire or wildfire land on the roof, it will be less likely to spread and reach your home's interior if you have an airtight insulation material on the roof.
It Is Eco-Friendly
Another thing with blown-out insulation is that it is eco-friendly. This is because blown-in cellulose insulation is made from repurposed or recycled wood products. The starting materials include things like used paper (think newspaper and books) and cardboard, among other used wood products.
If your roof is under-insulated (or your roof's insulation material is damaged), consider using blown-in cellulose insulation. Talk to a roofing contractor for more information on attic ventilation and various forms of roof insulation.
