Signs of an Under-Insulated House

Nova Fiberglass Insulation

Your home is always chilly, no matter how high you turn up the heat, especially upstairs.


Your once pristine insulation looks old, dirty, or flat – a clear sign you need to replace it or add more.


Snow melting quickly off your roof is a clear sign of an under-insulated attic, and can cause serious issues.  Snow that melts rapidly can refreeze on your eaves and cause leaks and ice dams which majorly damage your roof.


You upgraded your windows and doors, but your home is still drafty.


Your energy bills have skyrocketed as the seasons change.

According to the U.S. Department of Energy, 42% of a homeowner’s utility bill is spent on heating and cooling costs. That number goes up drastically when a home is poorly insulated. Without proper insulation, the heated or cooled air your heating and cooling system is working so hard to produce escapes through the walls and attic. Proper insulation can cut those costs by an average of 20%! If your home lacks the proper amount of insulation, or if your insulation is installed incorrectly, you can do severe damage to both your home and your bank account.

Symptoms of Insulation Issues:

  • High energy bills
  • Fluctuating temperatures
  • Chilly drafts
  • Cold rooms
  • Cold walls, floors, and ceilings
  • Rodents and insects in your home
  • Ice dams on your roof
  • Frozen pipes

Benefits of Fiberglass Insulation

Typically manufactured in two different forms — pre-cut batts and rolls, and blown-in loose-fill — fiberglass building insulation is used primarily for thermal and acoustical purposes in wall cavities, attics, and other critical open spaces in building assemblies. One of its key advantages is value. Fiberglass insulation has a lower installed price than many other types of insulating materials and, for equivalent R-Value performance (i.e., thermal resistance), it is generally the most cost-effective option when compared to cellulose or sprayed foam insulation systems.

Thermal Performance
Fiberglass insulation helps make buildings more thermally efficient by better retaining the desired temperature of enclosed spaces, whether they are heated or cooled. Its thermal performance reduces utility costs for building owners, conserves nonrenewable fuel sources and provides greater occupant comfort (when used in conjunction with appropriately sized heating and cooling equipment).

Moisture Resistance
When exposed to moisture, fiberglass insulation neither absorbs nor holds water. If fiberglass insulation does get wet during or after installation, installers should visually inspect it on all six sides for contamination. If the material appears free of visible defects, installers must dry it thoroughly to restore its full R-Value. Once the area surrounding the insulation has also been inspected, cleaned and fully dried, the fiberglass insulation can be reinstalled and will regain its original R-Value.

Fire Resistance
Made from sand and recycled glass, fiberglass insulation is naturally noncombustible and remains so for the product’s life. It requires no additional fire-retardant chemical treatments. Many building codes also recognize fiberglass insulation as an acceptable fire stop in wood- and steel-framed wall assemblies.

Acoustic Control
Fiberglass insulation is a naturally sound-absorbent material that significantly reduces sound transmission in wall, ceiling, floor, and HVAC assemblies. The first inch of fiberglass insulation in a building cavity can increase an assembly’s sound transmission class (STC) value by three or four points in some constructions. Each additional inch can further increase the STC rating by two points.

Recycled Content
Between 1992 and 2000, the fiberglass insulation manufacturing industry recycled more than 8 billion pounds (3.6 billion kg) of pre- and post-consumer glass containers, eliminating the need for millions of cubic feet of landfill space. Fiberglass insulation has significant recycled content, with some batt, roll and loose-fill insulation products containing up to 80 percent recycled glass. The other main ingredient in fiberglass insulation, silica sand, is an abundant, naturally renewing resource, limiting environmental impact in the manufacturing process.


yelp-logo-transparent-background-4I own a remodeling company called Evergreen Contracting Services LLC which is a highly rated company for value and quality and we only hire the best craftsman in the business, and I found Ken and his crew to be understanding to work with, excellent communication, knows the in and out of his business, we had a project renovating an old 1800 garage turning it into a gym, pool house space, and found it hard to meet and exceed code until I spoke to Ken, he guided me and provided all the needed documentation to satisfied the county officials, and what a great end result.

NOVA Spray foam did just as they promised and, more importantly, for the price they quoted. The two employees who ultimately installed the product were very nice, pleasant, and respectful. Bottom line: We are delighted with the install. Our house now holds a more stable temperature and no longer has hot spots. It used to be very difficult to cool our upstairs bedrooms; those days are gone! Pocketbook issues: For the last three billing cycles we have used approximately one third less electricity as the AC does not come on as often. Would we do this again? Yup! Do we recommend this installer? Yup! Do the neighbors think it’s cool? Yup!

yelp-logo-transparent-background-4I contacted Ken, at NOVA Spray Foam for a remodeling job I was working on in Upper NW DC. He came out the very next day, spoke to me about what the goal was for the insulation, gave us some great recommendations. Within two days we had a very competitive quote, and a starting date that fit our schedule. Ken and his team at NOVA Spray Foam, are simply the BEST! Very thorough, very professional, and know their job. Our attic and house clients are extremely happy with the way that their house is already feeling cooler(work was done in early Aug 2014), and are excited to know they will be saving money every month on their heating/cooling bill, as well as extending their HVAC systems life, as it is more efficient now. I highly recommend Ken and NOVA Spray Foam.
