Energy Efficiency – The Green Cocoon

Why Proper Attic Insulation Is Crucial

Attic Insulation, Closed Cell, Energy Efficiency, Save Money

Your attic does much more for your home than store your stuff. It is designed to provide a protective barrier for your home from cold, heat, and humidity. But in order for your attic to do its job, it must be properly insulated.

Traditional Insulation Not Effective

The Green Cocoon has almost two decades installing insulation and has discovered that traditional insulation isn’t effective in most cases! The most common types of insulation used in one’s attic are fiberglass and blown cellulose. The problem with those types of insulation is that many inexperienced contractors install them without sealing to prevent airflow. With fiberglass or cellulose, air can move quickly through the insulation and with that air comes moisture.

Escaping Heat Causes Problems

If heat is escaping into the attic from below, and the attic is not properly vented, the warm air will heat the roof causing ice d am s to form. Some contractors try to fix ice dams by increasing the ventilation in the attic. But what they should be doing is putting in proper insulation! It’s all about the R-va l ue.

In New England, the R-value requirements for an existing attic is R-38, but for new construction it requires a value of R-49! That’s because newer construction techniques are becoming more efficient.

Did you know that R-value is measured in an air-tight vacuum chamber and allows researchers to conduct physical experiments without any interference from the environment? Your wall is not a vacuum chamber and the materials do not perform the same in the real world, unless completely air-sealed like the chamber. R-value is not constant, so it’s important to use the right type and amount of insulation.

Closed Cell Spray Foam Recommended

Closed cell spray foam is the only insulation material approved for spraying directly against the roof deck because moisture can’t pass through it. This, along with the fact that the foam fills the holes and crevices, makes it the best insulation choice to prevent condensation in the attic.

Proper Ventilation

If you have properly insulated and air-sealed your attic, you won’t have heat loss or moisture build-up. We suggest installing a soffit and ridge vent, or two gable vents to help with air circulation, if you have an uninsulated roof.

If your attic is insulated with fiberglass or cellulose, and you have insulation covering the roof slopes, you need to have a vent behind it. As mentioned above, moisture can potentially pass through the insulation and condense on the roof causing a host of issues.

Reasons Not to Ventilate

If you have HVAC and/or ductwork in the attic, you don’t want to vent the attic because you will lose a lot of efficiency. The heating system will try to warm the house from a 10-degree attic and cool it from 130! A conditioned attic will prolong the life of your equipment as well as save you money with your heating and cooling bills.

Start Right and Properly Ventilate

If you have fiberglass or cellulose insulation already installed, then it is crucial that you have adequate and proper ventilation. But, upgrading your insulation saves money and efficiency in the long run. Don’t use ventilation as a way to solve inefficiencies with subpar insulation. That’s like putting a band aid on a bullet wound!

Monitor the Health of Your Roof During the Winter

Energy Efficiency, Insulation, Roof Health, Save Money

Many cities across the country were hit with a major winter storm last week, and for some, it was the first big one of the season. One area of the house that gets hit the hardest during a winter storm is the roof. Make sure to monitor the health of your roof during the winter to make sure it is strong enough to take the brunt of bad weather. If the snow isn’t melting quickly, it means that heat from your home isn’t escaping through your attic floors and then transferring from your roof to the exteriors. That means your roof is doing its job!

Bare spots and icicles mean heat is escaping

If your roof gets a decent amount of snow on it, make sure it’s not melting in specific spots. That means there’s heat loss likely due to poor insulation and/or ventilation in the attic. If that is the case, give us a call once the snow melts.

After a snowfall, every homeowner should take a look at their roof and check for hot spots—areas on the roof where the snow has melted. It’s normal for some melting around venting and fireplace exhausts, but you shouldn’t see any bare patches on your roof. A snow-covered roof means your insulation is doing its job.[1] If not, it’s time for a new insulation package!

Also, keep an eye out for icicles—another sign of heat loss. If your roof is warm enough to melt the snow but it’s cold enough outside for snow to refreeze, your roof is losing heat. That’s not healthy for your energy bills or the environment.

Remove some snow if it gets too deep

What about the weight of snow? If there’s ice too, that can be a heavy load. Add the weight of two layers of shingles and that’s one roof no one would want over their head. Generally, most roofs max out at about 20 pounds of snow per square foot, which translates to around two feet of wet snow or up to four feet of light, fluffy snow.[2]

Once you start hitting those levels, you may want to think about removing the snow. Otherwise, it could potentially cause your roof to cave in, which is a terrible experience in any weather, but particularly during subzero temperatures. Still, you can’t exactly get on top of your roof with a snow shovel. If you have an asphalt roof, you run the risk of doing serious damage to your shingles, which can cause your roof to leak afterwards—and all kinds of havoc as a consequence.²

If you don’t have the proper equipment to remove the snow yourself, hire a roofing contractor to safely handle the removal for you. It generally only costs about $100 to $300, and it will save your roof a lot of wear and tear.[3]

Install an ice and water shield

We suggest you install an ice and water shield over the first four feet of roof, on top of the sheathing—not just along the edges near gutters. This adds a second layer of protection against leaks and moisture where ice dams may occur, so if water gets in below the shingles the sheathing is watertight.

Another reason to add an ice and water shield is it seals around nails, unlike tar paper, roofing felt, or asphalt paper. If you have shingles on your roof, as most North American homes do, for every nail that goes through the tar paper there’s a tiny hole — an open invitation for water in your attic.

Check your attic (and garage) after a storm too. If you see frost on the sheathing it’s not a good sign. It means your attic isn’t properly vented for your specific insulation type or it is lacking insulation all together, which could lead to mold or rot. If you see any signs of mold or rot in your roof, call a professional remediation company.

Your roof and attic are crucial when it comes to protecting your home over the winter. Please contact us to schedule an appointment to make sure your insulation package is up-to-date.

Cellulose, Energy Efficiency, Insulation, Save Money, Spray Foam

The fall has officially arrived in New England and winter is approaching quickly! With temperatures already slipping below freezing in some areas, the thought of high heating costs is on our minds. Insulate your home and save money. By adding or upgrading your insulation, you can save money on heating costs, thus making your home more energy efficient. By using Efficiency Maine, you can save up to $3,000 by upgrading the insulation in your home!

The Green Cocoon is located just over the border in Massachusetts, but we also service our sister states like Maine. Maine is known for its diverse landscapes, lighthouses, and its delicious bounty from the sea. However, it is also known for its harsh winters. And, that has many homeowners bracing themselves for indoor drafts, cold floors, and hard-to-heat rooms. What if you didn’t have to put up with these home comfort pains this winter?

Why Upgrade My Home’s Insulation?

Many Maine homeowners don’t realize just how effective insulation can be at making their homes more comfortable and efficient. Insulation in key areas like the attic, basement, and exterior walls slows heat transfer into and out of the home. This means that in the winter, that valuable heat you’ve paid for stays inside your home, right where you want it. Cellulose and spray foam insulation are especially effective insulation materials (which is why we install them in homes here in Maine!)

With the right insulation upgrades, you can expect benefits like:

Fewer drafts and cold spots
Warmer floors
Lower annual heating/cooling costs
Enhanced overall comfort
Greater home energy efficiency
Reduced outside noise

When insulation is paired with proper air sealing to eliminate air leaks, the benefits go even further!

Insulate & Save up to $3,800 with Efficiency Maine Rebates

While an insulation upgrade does have an upfront investment, there are valuable local incentives available through Efficiency Maine to offset that cost. As a matter of fact, upgraded insulation helps you save money on your heating bills over time, and insulation has a remarkably short payback period.

Currently, you can receive up to $3,000 on an insulation rebate, $400 on an energy assessment and another $400 when you air seal troubled spots. The Department of Energy graphic below has a useful cross-section diagram illustrating the most common air leakage spots.

5 Easy Ways to Increase Energy Efficiency and Save Money

Energy Efficiency, Save Money

With winter approaching, The Green Cocoon has five easy ways for homeowners to increase energy efficiency and save money, besides using our fabulous spray foam insulation! As the weather gets cooler, your furnace will start to come on and that means you’ll be using more energy. Consequently, your heating bills will increase. Try these five easy DIY (do-it-yourself) projects to help cut down on energy loss and expenses.

Replace worn weather stripping around doors and windows

Did you know that worn weather stripping can create drafts and let cold air in? This puts a high demand on your furnace and takes away your comfort. Replacing it takes little time and is a low-cost, high-impact solution.

Caulk around windows to increase energy efficiency

Cracks and crevices are a source of heat loss. They can also be an entryway for water/moisture, as well as for undesired insects. Preventative maintenance, such as caulking, can improve energy efficiency and prevent costly repairs.

Change your furnace filter

A dirty furnace filter means less efficiency and that costs money! Check your furnace filter monthly and if it’s dirty, change it or have it changed. Moreover, have a technician come in and inspect the entire furnace at least once per year.

Update light bulbs to LEDs to save money

LED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs—especially ENERGY STAR rated products—use at least 75 percent less energy, and last 25 times longer than incandescent lighting.¹

An automatic thermostat increases energy efficiency and saves money

You can save money and increase energy efficiency on your heating and cooling bills by simply resetting your thermostat when you are asleep or away from home. You can do this automatically, without sacrificing comfort, by installing an automatic setback or programmable thermostat.
