With the different seasons all over the world sometimes it can get extremely cold or extremely hot, so there’s always the need to regulate the temperatures around us to feel comfortable. We all use in-home heating and cooling. But without the capacity of an insulating material to resist heat flow (R-Value), your hard earned money is practically leaking out of your home in the form of hot air in the winter or your house gets “baked” in the summer increasing your cooling costs.
The type of insulation you need or have installed varies from location to location and we can provide some helpful advice to our customers about the proper insulation for their home in Nashville. Plus we can take a look at your roof to discover any problem areas or leaks that may be impacting the internal home comfort you experience.

There are many ways to insulate your home. Some of the most common Insulation materials are:
Mineral Wool: A material made up of volcanic rock and recycled slag melted at extremely high temperatures with fibers spun together. This works perfectly as a permanent insulation that doesn’t need to be replaced, is excellent for preventing fires and doesn’t absorb water. Installing Mineral wool is a job best left for experienced installers. If you do it yourself and don’t use the proper gear, you’ll most likely experience some eye, skin and respiratory irritations, resulting in a lot of itching and discomfort.
Cellulose: If you’re an advocate of going green, this is the go green option. It’s made up of about 75% post-consumer recycled newspapers, it’s efficient, non-toxic and affordable. Cellulose is also an excellent air-blocker, which is great especially if you have any cracks or small holes where warm air can escape from.
Fiberglass: This is possibly the most well-known insulation material of them all. It’s made of glass that has been spun into fibers then woven and coated with a binding agent. Compared to other insulations, fiberglass has to be installed perfectly in order to retain its rather lower R-value. However, even with a perfect insulation, if there are any gaps whatsoever or if it gets wet or is too tight or too loosely packed, up to 50% of its R-value can be lost. It has to be installed in a place where there are no air leaks and moisture can’t get to it.
Polyisocyanurate: This is a closed-cell, rigid foam board insulation. It has a high thermal performance in the home building market and because of this it’s the product of choice for many energy-aware homebuilders. It has one or both sides of the insulation wrapped in foil so you can identify it quite easily, it’s cost effective, eco-friendly and has the highest R-value.
Other Foil Insulation: Also known as reflective insulation. It basically uses a foil finish to deflect hot air from coming in (summer months) or going out (winter months) through your roof. But what is the R-value and permeability with reflective insulation? Can it breathe? Permeability is important to avoid moisture from getting trapped and creating mold.
