"Dynasty Decking has my vote for best construction team. They are not only honest and trustworthy but kind and understanding. They worked with my budget and troubleshooted with me so that I got the best possible results. I recommend them to all my friends and family. They’re even certified through the state unlike a few of the other people who gave me outrageous quotes."

Insulation questions, answered by experts

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

We recommend that you cut batts of fiberglass insulation with a sharp utility knife. However, in a pinch, you can use tools such as a box cutter or even a pair of scissors. No matter what cutting tool you use, just make sure it’s sharp so you get a clean, straight cut. Always cut along the back (foil) side of the fiberglass, rather than the “fuzzy” side of the material.
