308- Tips on Selecting Insulation Material for Your House

When your house is properly insulated, you can cut your energy consumption by as much as 50% and possibly more. It is perfectly possible for insulation to be installed on already built homes. The first thing which you need to decide is what type of material you will use. Here is some practical advice to help you make the best choice for your house.

Tips on Selecting Insulation Material for Your House


Examine the structures requiring insulation.

Most of the heat lost to the outside environment escapes from the loft (up to 35%) and from the walls (up to 33%). That is why these two structures have to be insulated first. Then you can move onto the floor and windows. In order to pick the best type of material, you have to check how these structures are constructed. Homes built after the 1910's typically have external walls consisting of two layers with a gap in between them. If this is the case, the material can be installed directly into the cavity. If the wall consists of a single solid layer, then you will have no choice but to use external panels.

Consider the installation difficulty and cost.

Some insulation materials are more difficult and consequently more expensive to install than others. You have to take this into account when making a choice. The rolls and bats are typically the easiest to install as they require manual placement. They are among the top options for DIY fans. The external solid panels are also inexpensive to install, but this job has to be done by specialists due to the risk of falling and injury. The blown-in and foam materials require special equipment for installation and this leads to higher costs.

Calculate the R-value carefully.

The R-value is a measure indicating the ability of a material to resist the heat travelling though it. The higher it is the better. The R-value depends on the natural properties of the material and on its thickness as well. That is why when you select a material, you have to calculate its R-value per inch precisely based on its thickness.

Evaluate materials based on quality and durability.

You have to ensure that the material will retain its properties and R-value for as long as possible. It is best if you pick a material which is water-resistant like fibreglass or foam, even if the price is higher. Still, any moisture must be removed before insulation is installed. You have to check the useful life of the material as well. The longer it is the better.

Compare the different insulation materials carefully to make a final decision.
