When your home is properly insulated, you can cut your energy consumption by half and possibly more. This will help you generate great savings for many years to come. However, installing insulation is not a simple task. You have to prepare carefully to ensure that you will enjoy the best results and keep costs down. Base your choice of material on the following major criteria to get exactly what you need and want. You may want to check out see this for more.
This is the measure of the thermal resistance of a particular material. Simply put, it indicates how well a material can insulate a particular structure. It is measures in plain numbers per inch or centimetre of thickness. The higher the R-value is the better the insulation will be. Most materials have R-value between 3 and 8 per inch with fibreglass and spray foam having some of the highest values.
It is important to note that the R-value depends not only on the nature of the material but on its form as well. Blown-in and foam materials can fill in cavities more perfectly than blankets. Additionally, the thicker the layer of the material is the better the insulation will be.
You have to check how well the material will perform in the long term. You would want to invest in a material which is weather resistant and water resistant, in particular. Its structure and properties should not be permanently affected by moisture. Fibreglass, for instance, may contact when wet, but it will dry quickly and expand. This will not happen with cellulose, however.
The longer the useful life of an insulation material is the better. This will help you save money, time and effort on replacement. Most materials have a very long useful life with some manufacturers claiming that their fibreglass products can last for 100 years. You should check what supports the claims and what the warranty or guarantee is. The manufacturers making more durable materials will feel comfortable with giving you a longer warranty.
You have to determine which type of material will be most suitable for you given the structure of your house and the scope of the home improvement project. Most buildings constructed in the 20 century and afterwards have wall cavities which make it possible for blown-in, foam material or blankets to be installed. Still, it is also possible to install panels on the outside of the house. Some materials require professional installation while others are suitable for DIY installation as well.
You need to calculate the total cost of the material based on the price per square foot or metre and on the size of the area which you plan to insulate. It pays off to invest in a better material even if the price is higher. Consider all possible sources of funding including special loans and insulation grants.
