Best Insulation R-Value

Energy Star, a government-backed symbol for energy efficiency, recommends different R-values for insulation depending on the geographic location of the property. Depending on the climate of your locality, you can decide which r-value insulation suits you the best. Is the lowest r-value or the highest r-value that you should go for? 

Knowing this information is essential especially when you’re in the process of choosing the right insulation you need for your home. However, when you’re working with a dependable and reputable insulation contractor, they will also surely recommend the best kind of insulation according to your needs. Let us look at a list of lowest to highest R-value insulation.

Insulation R-Value

1. Cellulose: cellulose is the lowest r-value rated insulation with its r-value ranging between R-3.2 and R-3.9 per inch. Cellulose is the least expensive and easy to install. A thick layer of cellulose can be installed to provide high resistance to heat.

2. Fiberglass: next to our list is fiberglass, with again low r-value ranging from R-3.1 to R-4.3 per inch. Fiberglass insulation is primarily installed between studs, rafters, and joists.

3. Spray Foam: Spray foam insulation is available in two types – open cells and closed cells. Open-cell spray foams have an r-value of R-3.5 per inch, while the closed cells have has an r-value of R-6.0 to R-6.5 per inch.

4. Rigid Foam Board: Rigid foam insulation is available in the market in different materials polystyrene with r-value ranging between R-3.8 to R-5.0, polyurethane with an r-value of R-5.5 to R-6.5, and polyisocyanurate with R-value of R-5.6 to R-8.0.

You can know the best r-value for your house either by contacting a professional or consulting your neighbors who have already insulated their houses. It is always a good idea to have the right insulation in place to ensure the effective utilization of energy.

Energy Saving Insulation

Insulation SavingsInsulation helps save on energy by restricting the transfer of heat from walls, attic, and roof. In a well-insulated house, warm air does not escape outside so it is best in keeping the house warm in winter and cool air is also restricted to pass outside in summer. The energy-saving property of insulators has urged many families to have their house insulated and save on electricity costs. Insulation saves energy by:

1. Sealing air leaks: Walls with cracks may provide an escape to warm and cool air pushing the ACs to work on high power mode. The insulator can provide a seal to the crack to prevent the warm air from escaping the walls.


Installing Roof Insulation

Roof InsulationInsulating the roof of your house can keep your home warmer in winter and cooler in summer. It can also help reduce utility bills and, of course, increase the overall comfort in your home. Follow the guide below for easy installation of roof insulation.

1. Contact an Electrician: Before beginning to install roof insulation contact an electrician to check the condition of the wire. If you own an older house, get the pipes checked for any leakage.


Best Way to Insulate an Attic

Insulating the attic is also a way to seal the air leakage. Overall, you can get more energy savings and a more comfortable home with a well-insulated attic.

Here is a short guide that will teach you the best way to insulate the attic.


Insulation Inspection

Insulation InspectionHave you inspected your home’s insulation lately? When your home is under-insulated, it feels less comfortable. It seems like it’s colder even when you have the heater on or warmer even when the AC’s turned on – these, of course, depend on the actual climate or weather in your area. Insulation inspection is necessary to ensure that you’re getting the most out of your home’s insulation.

Ideally, inspection should be done by a qualified insulation contractor. They can help you accurately determine whether the insulation in your home works perfectly or whether there are parts that have to be replaced already. This is usually done through a touch test or thermal imaging. With thermal imaging, fluctuations in temperature in some areas of your home can be determined.
