Choosing the Right Insulation for New Home Construction

August 18, 2020 Published by Leave your thoughts

High-quality insulation is a great investment for your new home. While it will add some money to the initial construction costs, it will also save you quite a bit of money down the road, as it will result in better control over interior air temperatures and make it so your HVAC equipment doesn’t have to work nearly as hard to maintain your desired temperature.

Of course, there are many different types of insulation to choose from, so how do you know which one is best for your purposes? Here’s a quick overview of some wall insulation tips in Brooklyn, NY and the various kinds of insulation you should consider:

  • Fiberglass: A very common, traditional form of insulation used across the country, fiberglass insulation is made out of very fine glass fibers. It is generally the least expensive option, which can make it appealing for homeowners on a budget, but it’s also going to be the least effective, giving you the lowest R-value and still allowing airflow into the attic.
  • Cellulose: Another very common type of insulation material, and possibly the oldest on the market, this can be either blown in or installed as loose fill insulation in an attic floor. It’s made out of recycled denim or newspaper. It’s an inexpensive option, but will settle quite a bit over a long period of use, and doesn’t create a very effective air seal.
  • Spray foam: Spray foam insulation is the most energy-efficient kind of insulation you can purchase if your goal is to create an air barrier to the attic. These foams are capable of expanding to up to 100 times their original size, allowing them to fill holes and cracks of all sizes and shapes. This foam is made out of organic chemical compounds from petroleum extracts, which means they’re environmentally friendly and safe for use. This kind of insulation is also Class 1 Fire Rated for use in attics, meaning it will not be an accelerant or catalyst should you have a fire start in your home. Finally, because it doesn’t retain water, you don’t have to worry about it encouraging mold growth. The major drawback is that it’s more expensive, but again, you get what you pay for.
  • Foam board: Foam board or liquid foam insulation core materials are often used for unfinished walls, ceilings, floors and roofs in new construction. They’re generally a better option than some of the traditional types of insulation, as they offer better R-value and do not take as long to install, but they lack the versatility of spray foam in that they cannot be blown into small nooks and crannies, where extra protection against airflow is needed.
