R-value is the unit of measurement used to gauge a material’s ability to reduce the rate of heat flow. Everything has an R-value and in insulation it is used to rate the effectiveness and quality of products. Different products have different R-value characteristics which are often compared by inch-depth. A standard fiberglass batt has a different R-value per inch-depth than loosefill fiberglass, cellulose, JM Spider or spray foam insulation.
We use insulation most commonly in residential construction within the wall and ceiling cavities. Its purpose is to hold heat within the conditioned spaces, the interior of your home, and slow down the rate of transfer to the outdoors. Walls are most commonly insulated with Fiberglass batts which have the lowest R-value per inch-depth. JM Spider Custom insulation is an innovative system that creates a higher r-value per inch-depth using loosefill fiberglass and resin. Spray Foam insulation, in either ½lb open-cell or 2lb closed-cell offers the highest r-values. Spray Foam is also excellent in areas that are difficult to insulate traditionally such as Floor Joists & Cantilevers.
For Attics the standard remains loosefill fiberglass insulation. At IDEAL we utilize Climate Pro insulation developed by Johns Manville, one of the largest insulation manufacturers in North America. Climate Pro is formaldehyde free and offers ease of installation to ensure your attic will be insulated to a quality standard with minimal heat loss.
Insulation within finished wall and floor cavities are difficult/impossible to improve without renovation. Flat ceiling attic spaces on the other hand are readily accessible and often easy to upgrade the insulation R-value. During an attic upgrade inspection IDEAL will identify the current R-value of your attic insulation and specify the additional loosefill fiberglass insulation required to achieve our recommended R-Value of 50. Ventilation and vapor barrier performance is also considered and scope of work quoted. By increasing your attics insulation you can expect increased comfort within your home and potential savings on your energy bill.
