Insulating Raised Floors
Insulating Raised Floors – California Requirements
For Californian contractors, there are a few values that must be true in order to receive your energy compliance credit when insulating raised floors. The first thing to remember when insulating raised floors is that the insulation must fit completely and entirely into all compartments, end to end and side to side. Also the raised floor insulation must be in contact with the air barrier, not the vapor barrier, while making sure that the insulation is cut and split for plumbing fixtures or wiring.
Insulating Raised Floors – Mechanical Fastening
Another thing to remember when insulating raised floors is to have the insulation mechanically fastened, so that it will not displace during the drywall phase of the job. Mechanical fastening is also the best option when it comes to support for the insulation. Rods work well every twenty to twenty-four inches, but netting or fabric also works great, as it doesn’t compress the insulation.
Insulating Raised Floors – Air Barrier
When insulating raised floors, it is vital that the insulation is actually against the air barrier, to gain the maximum benefit. Once again, mechanically fastened netting or fabric will insure that your insulation doesn’t sag or droop, which can cause an unsightly problem, and even more importantly, holes in the insulation, making your house draftier than it need be.
Insulating Raised Floors – Energy Compliance
Insulating raised floors can save you hundreds of dollars on your home heating and cooling bills. Please remember that when insulating your raised floors, the installer needs to fill out a CF6R form. These forms are required by the city and must be filled out to ensure your energy compliance credit when insulating raised floors, or anything else.
Insulating raised floors is a great way to save money and increase your level of comfort in your own home. Just remember to mechanically fasten your insulation, preferably with a fabric or net, to hold the insulation in place and to keep it as close to the air barrier as possible. Remember, it is very important to have nothing else between the insulation and the outside air. Follow these tips and insulating raised floors will be a breeze!
