Types of Loft Insulation

Loft insulation is one of the most important aspects of the home. Your loft is essentially a part of your house that you don’t see while in use. It houses your attic and the things that you keep in there. Getting this type of insulation done properly is vital if you want to have an energy-efficient home and be at the top of your energy bill in winter as well as summer. There are a lot of different options when it comes to loft insulation so it can be confusing knowing what you need to get done.

insulating material


There are some basics fundamentals when it comes to loft insulation. The first is that it should be waterproofed with a type of insulating material that is durable. There are some types of foam, for example, that are made to resist moisture while still being very airtight. Another option is to spray foam, which is more affordable but also fairly effective at insulating against moisture. You should choose a spray foam option for most types of attic insulation.

Next, you need to figure out the right way to install the insulation. Most people just run a few inches of insulation along the ceiling. This isn’t a bad idea if you have a reasonable amount of space. However, if you have a tiny crawlspace or even a bathroom, this isn’t going to do the trick. Ideally, you’d want to run a three-inch wide strip along the bottom of the walls and up the entire wall. This is much more effective than just running a couple of inches of insulation along the ceiling.

When choosing the insulation, you should pay close attention to the R-values of the product you buy. This will give you an idea of how effective the product is to reduce heat loss. Also check the type of insulation used. More than likely, if you’re paying a contractor to install the foam, it will be made out of fiberglass or another less costly type of fiberglass. If you’re installing the insulation yourself, you may be able to use a reflective type of insulation, which would be cheaper but would wear out more quickly.


best location for foam insulation


Now that you’ve chosen the type of insulation to be installed, you need to know where to install it. The best location for foam insulation is right above the attic. Installing it directly above the roof is not a good idea, as the water vapor from the roof may escape and eventually cause damage to your home. You also don’t want to cut into the attic in order to place it. Instead, install it flush against the rafters and siding.

As mentioned earlier, this type of insulation is very affordable. It is possible to install it yourself for about two hundred dollars per square foot. This is generally less expensive than the R-values, which are generally between one and three. If you are insulating a garage, you can expect to pay anywhere from five hundred to a thousand dollars. These prices are much lower than what you would pay for traditional types of insulation, which can add thousands of dollars to the cost of your home.
