If you have an old home, keeping it warm can be a difficult and tricky task. Houses that were made before 1940 usually do not have insulation and even if they were, the products used have already deteriorated, which means heat is now escaping and cold air is getting inside your home through the roof. Fortunately, there are lots of thermal insulation options in the market today and picking out the best one for your home depends on lots of factors. Given that, here is a guide to help you with your old home’s roof insulation project.
Do You Need Insulation?
The first thing you need to find out is if you have insulation. It is easy to determine if you have attic or roof insulation as you will notice loose fill in between ceiling joists. Checking your exterior walls for patched holes is also a surefire sing of blow-in insulation. Old houses could be drafty places and there are several areas where warm air can leak out. Find out where you might be losing heat like window cracks, ducts, recessed lighting, and even electrical outlets. Keep in mind that the main site of heat loss is usually on top of the house and that is why it is important to have proper roof insulation with the help of a roofing contractor.
What To Do With Existing Insulation
A few of the early materials used as insulation that can be left in place are mineral wools and other mundane materials like newspaper, wood shavings, seaweed, and corncobs. The materials that create the most concern are those that contain urea-formaldehyde and asbestos. If you suspect that your house has asbestos, it is best to have it tested or call an expert to assist you.

What Form Of Insulation Do You Use?
There are four general categories for building insulation. These are loose fill, rigid boards, expanding sprays, and batts. Rigid and batt insulation are used during a major renovation that needs the walls to be replaced or if you are going to install insulation on spaces that are not commonly used like attics. Loose fill is the most typical insulation retrofit for old homes since it can reach spots where the installation of insulation is difficult.
How Much Insulation Do You Require?
The R-value of the insulation will depend on where you live and what part of your home you plan to insulate. The material with the higher R-value provides better insulation. The R-value range anything between 0-40. Warm weather places need to have smaller value while locations with chilly climates need high R-value. You can also check the website of the Department of Energy if you wish to know the appropriate R-value for your region.
Where To Install Insulation?
The answer to this question differs from one old house to another. As mentioned earlier, roof insulation is extremely important. It is best to start at the attic since warm air usually tends to rise then cool air tends to fall. In case the attic is not finished, the insulation must be installed on the floor, In case you are using the attic as a living space, then you should place the insulation between the rafters. You also need to make sure that there is a proper ventilation between the insulation and the exterior of your home. Never block the ridge, soffit, or gable vents because if you do, it might lead to moisture problems.
