The Basics of Loft Insulation

Loft insulation is constructed in an extensive array of different materials. Green credentials, price, efficiency and application are all significant factors to consider when selecting the ideal loft insulation product for your particular project. Depending on the style and size of your loft insulation you may have several options in your choice of insulation. Ranging from cellulose to fiberglass and even insulating paint, insulation provides the desired protection from heat or cold and offers comfort. Although there is a significant amount of variation in insulation types, you’ll find most all provide good protection from dampness and heated air. The amount and type of loft insulation you select will depend on the climate you live in and the specific conditions of your loft will face throughout the year.

types of loft insulation


The major types of loft insulation are perforated metal, spray foam, blown-in insulation or rigid plastic membrane. Each offers different benefits depending on your application needs, and will vary in price. If your home has a high roofline and is in constant wind, it is imperative that you choose rigid plastic membrane as your roof insulation material. The reason for this is that this type of material is able to conform to the shape of the roof, offering superior performance where other types of loft insulation may not perform as well. When selecting this form of insulation, it’s important to carefully measure the height and width of your roof.

Installing loft insulation may require professional help and installation. If your home is not properly insulated, you will find your heating and cooling costs rising, with a correspondingly higher electric bill. The best way to avoid costly complications in the future is to consult a reputable installer and get an estimate of the cost of installing the necessary materials to properly fit your roof. Make sure you have chosen a quality product that will protect your home and your wallet.

When selecting the right loft insulation, it’s important to know what type of insulation will work best for the location you are planning on installing it in. There are different types of insulating materials, each offering its own benefits for both insulation and air conditioning. Knowing which type will work best for your situation can help you make a better decision about your purchase.

The two most common forms of attic insulation are drywall and cavity wall insulation. Drywall is a great option if your home has a higher ceiling or is already insulated but lacks a basement. For those homes with a flat roof and a decent amount of living space, cavity wall insulation may be the best choice. This type of loft insulation can be installed in either an open or closed wall position, and is usually a sheeting of fiberglass, corrugated fiberboard or a foam insert held in place by nails or metal staples. Most installers will recommend cavity wall insulation for homes with a lower ceiling, high windows or where electrical outlets need to be located near the walls.

consider before insulating your loft


Whether you decide to install drywall or cavity wall insulation, it’s important to use the proper equipment for the job. Choose a contractor that has many years of experience in constructing and installing all types of insulation, and who has proof of insurance to protect you in the case of damage. A good insulating contractor will be able to give you cost estimates for both options, and help you determine which will work best in your particular situation. Remember that most homeowners don’t have much extra money for a project like loft insulation, so it’s important to get the most bang for your buck.
