Before you buy, build or remodel your home, it is important to spend time speaking to an Alameda County insulation contractor that serves the major cities of Oakland, Fremont, Hayward, San Leandro, Piedmont, Castro Valley, Berkeley, San Leandro, and the smaller towns of Albany, Ashland, Cherryland, Komandorski Village, and Mount Eden. about your house’s energy efficiency. Some pertinent questions to ask would be:
- What type of insulation should I use in this attic?
- Which areas of the house should be (or are) insulated?
- Does the insulation meet the recommended local and national insulation codes?
In order to keep your home as energy-efficient as possible, insulation should be installed in as many areas of your house as possible, not only the outside walls and attic. Some of the areas you may want to include are:
- Sloped walls and sloped ceilings
- Slab perimeters
- Floors above an unheated place, like a garage or a porch.
- Walls of the basement
- Interior floors and walls, especially where you need extra sound control
- Floors that are above unconditioned basements
- Attics and Crawl Spaces
R-value is the way insulation is identified and labeled. The “R” represents the resistance to heat flow; and the greater the insulating power the higher will be the R-value. Usually this number will be printed on the bag or on the label of the product. Most of the time, the R-value will be written on the facings of the rolls, too. If there is no facing on the insulation, R-values are written on the product or with striped coding.
You will have many insulation choices which include: foam, fiber glass, mineral wool, and cellulose. The types that are most frequently used for homes are cellulose and fiber glass.
This insulation is one of the most meticulously tested building materials for over fifty years, which supports the claim that fiber glass is safe to use if you follow the manufacturer’s recommendations. This product can cause irritation or itchiness in some people.
This insulation is still mainly untested, which leaves questions among those in the building industry about its health and safety. It is made of 20% fire retardant chemicals; however, the limited testing so far indicates the possibility of serious health concerns.
