Insulation Matters In The Pacific Northwest

Properly Insulating Your Home Can Save You As Much As
17% On Your Annual Energy Bill

We frequently discuss heating systems, such as furnaces and heat pumps on our website and in our Idea Center. These necessary systems heat our homes in a way that we can physically feel.  However, there is an unsung hero in home warmth and efficiency that just doesn’t get enough credit: insulation. In our wet, cold, cut-you-to the-bone Pacific Northwest winters, keeping heat and cool air where it should be is crucial—and that’s exactly what proper insulation delivers. According to Energy Star, adding insulation can save you up to 17% on your annual home energy bills.

There are four types of insulation available from Washington Energy Services. Each type serves a unique purpose, and they all work together for optimum home comfort and efficiency.

Interior And Exterior Wall Insulation

When you hear the word insulation, this is probably the type that comes to mind. This insulation is installed in the cavity between the interior and exterior walls. This is common in new construction, but in older homes, it is often a retrofit installation. To install, small openings are inserted into the walls for the insulation to be blown in.

Interior and exterior wall insulation act’s as a barrier to the elements. Just as important, it reduces interior heat loss through the wall.

Duct Insulation

If your home has an air-forced heating and cooling system, your ducts act as a thoroughfare to distribute air. Unfortunately, 20 to 30 percent of this air can be lost through the ducts, resulting in energy loss and uncomfortable temperatures. It’s also a safety issue as crawlspaces are dirty and dusty, and these particles can be picked up by the ducts and spread throughout your home.

Duct insulation seals the ducts to stop air leakage, improve your home’s energy efficiency, and help you manage temperatures. It also keeps dust out of the ducts, and therefore, out of the air your family breathes.

Crawl Space Insulation

Believe it or not, most Puget Sound area homes have no insulation in their crawl spaces. While they’re on the outside of the heated part of your home, insulating these areas can have a big impact on your home energy usage because it keeps heat from escaping the home… and money from escaping your wallet.

Attic Insulation

Attic insulation from Washington Energy Services is environmentally friendly, flame resistant, and energy efficient—an all-around win-win. The insulation is cellulose-based and blown in by one of our technicians. We also offer a fiberglass insulation option, which we may recommend based on your unique home.

Insulation may not be as noticeable as your heating system, but it’s crucial to your home’s comfort and energy efficiency. If you know your insulation is lacking, call us for a free in-home estimate. If you’re unsure of your home’s insulation quality or locations, opt for a Home Energy Audit. We’ll identify insulation weak spots, locate opportunities for insulation placement, and show you where you’re losing valuable heat and energy.

Tips for safely insulating your home

Posted On: Filed Under: Home energy audit, Insulation 3 Comments on Tips for safely insulating your home

Insulation is an important part of reducing energy bills and increasing comfort. But did you know that you can create safety issues in your home if you do not install insulation correctly? Here are three tips to installing proper insulation so you can avoid:

  • Carbon monoxide poisoning
  • Moisture problems and mold
  • Fire hazards from lighting

1. Be sure to conduct carbon monoxide tests on appliances before insulating and air sealing your home, especially in homes with natural gas. On a recent home energy audit, Washington Energy’s home performance team discovered unseen carbon monoxide coming from an old gas water heater. With a drafty house, and the water heater in the basement, it wasn’t enough gas to trip the CO detector in the main part of the house. However had the homeowner installed full insulation and air sealed the house without knowing, they may have locked in that gas and exposed their family to high levels of carbon monoxide.

2. Prevent moisture problems by letting your house breathe. In the previous article we discussed the relationship between your home and indoor air quality, and we highlighted the need to seal the penetrations bringing unwanted air through your home. But did you know that you can overseal? Most older Seattle homes don’t need to worry about this, but if you have new construction or if you are putting in your own insulation, this is important to consider.

New construction (less than 20 yrs old) has been built tighter – with fewer penetrations than older homes. These homes may actually need added ventilation installed when you insulate, to ensure healthy air inside the home.

To make sure your house is breathing properly, start by ensuring that bath fans are vented directly to the outside. Then when insulating, baffle the soffits! It may sound like pirate-speak but it’s important to keep your vents under the eaves of the roof free and clear for air transfer In layman’s terms: the eave vents are called soffits. Baffles, which are foam or cardboard pieces, fit around the inside of the soffit to keep the insulation from clogging up the vent. If insulation blocks the soffit vents the heat and moisture rising up through your house toward the attic, cannot escape. This will result in condensation forming in the attic and can eventually soak or ruin your insulation plus potentially affect your roof shingles. But most importantly, it can create the environment for mold and mildew to grow.

A licensed insulation contractor will know where and how much venting will be enough, and how to baffle a soffit too.

3. Insulation and can lights may not mix well. If you have recessed “can” lights, those spotlights commonly built into the ceiling, you may not know that some of them are rated to be surrounded by insulation and some are a fire hazard if they are surrounded by insulation. Inside the light fixture look for the rating stamp IC (insulation contact). IC lamps can contact your insulation safely. If you do not see IC, keep insulation 3 inches away from the light fixture and use a wood or metal barrier to ensure they don’t touch. Consult the manufacturer of the lamps or an electrician, if you have questions about safe installation. There are also specialized boxes that can go over non-IC rated cans so you can air seal the cans without making them a fire hazard. To ensure your cable, wiring and insulation are an appropriate match, please research carefully before installing them yourself.

And one final tip. If you are going to invest in adding insulation, for just a small amount more a home performance contractor can add duct sealing and duct insulation. They will carefully seal the joints in exposed portions of your duct system and then insulate around the ducts. This works to ensure that the heat travelling in your ducts gets to the rooms you need it in. When combined with insulation and air sealing, these three measures can improve home comfort and reduce energy costs by up to 30%.
