Insulate Your Home and Save Money

Insulation Tips

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?

The Green Cocoon Closed Cell Spray Foam

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.

Take Advantage of Efficiency Maine Rebates with The Green Cocoon

As a Residential Registered Vendor with Efficiency Maine, we’re here to help homeowners on the southern coast of Maine save on their next insulation project. In addition to assessing the unique insulation needs of your home, we will help you determine the rebates for which you qualify.

Prepare for a “Shake, Shiver and Shovel” Winter with Eco-Friendly Insulation

Home Maintenance Tips

According to Farmers’ Almanac (Almanac), we are in for a “Shake, Shiver and Shovel” winter. According to their extended forecasts, this winter season will have plenty of snow, rain, and mush—as well as some record-breaking cold temperatures! With the temperature cooling, it is the perfect time to save money and prepare for the shake, shiver and shovel winter with eco-friendly insulation. Make your home more energy-efficient by replacing your old insulation one of The Green Cocoon’s eco-friendly insulations.

The first day of winter and the shortest day of the year, officially arrives on December 21, 2022, but that doesn’t always mean that the cold temperatures and snow storms will wait until then. So what’s in store for New England? Read on.

According to the Almanac, “The first bite of winter should come earlier than last year’s. December 2022 looks stormy and cold nationwide with an active storm pattern developing and hanging around for most of the season over the eastern half of the country.” We think there will be a white Christmas this year!

New Hampshire Known for Crazy Weather

Winter is coming - Insulation needed from The Green CocoonIf you live in New Hampshire, you are no stranger to crazy winter weather. According to NOAA’s National Centers for Environmental Information, the coldest temperature on record in New Hampshire (-50°F) was on January 22, 1885. That was at the summit of Mount Washington. Likewise, many winters in New Hampshire bring snow, rain, ice, and chilly temps.

A well-insulated home is crucial, especially the week of January 16-23, 2023. The Almanac raises a red flag for bouts of heavy rain and snow across the eastern two-thirds of the country. Additionally, this will be followed by what might be one of the coldest outbreaks of arctic air they have seen in several years. How cold? Try 40 degrees below zero!

Use Eco-Friendly Building Insulation

Many homeowners don’t realize 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 in and out of the home. This means that in the winter, your expensive and valuable heat stays inside your home, right where you want it. Cellulose and spray foam insulations are especially effective insulation materials.

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

  • Fewer drafts and cold spots
  • Warmer floors
  • Lower annual heating/cooling costs

The Green Cocoon - Thermal Bridging Photo

Understanding and Managing Thermal Bridging

Home Maintenance Tips

When you are ready to insulate your living space, you may be contemplating what R-value you will need. And why not? It is the most widely accepted measure of insulation and often aligns with a minimum code requirement. But assuming that your wall assembly will realize the R-value of your insulation ignores a crucial variable in building science—thermal bridging. Understanding and managing thermal bridging will make your living space more comfortable. And, it will save you money!

What is thermal bridging?

Thermal bridging is when a particularly conductive (or poorly insulating) material allows heat flow across a thermal barrier. Physics dictates that hot wants to go to cold and a thermal bridge is a perfect invitation. The best analogy is to think studs within an insulated wall. The insulation on either side of a stud will do its job of limiting heat flow. But, the wooden stud, which has a much lower R-value, will not. These bridges can become expressways of heat loss.

green-cocoon-insulation-ma-open-cellHow does this work in a home?

To understand and manage thermal bridging, let’s continue with the stud example. The typical R-value of a 2×4 wooden stud is 4.4, while the insulation on either side is much higher—typically greater than R13. The result of this bridge is heat being transferred and a significant loss in the wall’s effective R-value. In a wood stud wall with R20 insulation, thermal bridging can reduce the effective R-value to as low as R15. One of the worst thermal bridges is a metal stud. This can reduce effective R-value by as much as 80 percent. Along with studs, other typical building materials that create thermal bridges are metal fasteners, plates, headers, and windows. Typically, you can observe these all around a house—roofs, walls, fenestrations, for example.

The impacts of thermal bridging

If you are losing heat through thermal bridges, the efficacy of your climate control system decreases and uses more energy. Furthermore, these bridges can create cold spots within your walls where condensation can easily form. This moisture can produce a whole host of issues to the wall cavity—mold and mildew or rot, to name a few. Excessive moisture also challenges the structural integrity of your wall.

How do we prevent or limit thermal bridging?

Luckily advancements in building science and common sense can really help limit thermal bridging. Realistically, most homes will have some thermal bridging happening, but there are tools at our disposal to help prevent it.

  1. Exterior insulation – According to Havelockwool.com, a better term would be “out-sulation.” This means that by wrapping the exterior of your home in insulation you can prevent (or dramatically reduce) the common thermal bridging via wall studs. Cork is a great option. You can spray foam the exterior, add rigid board or Rockwool as well.
  2. Advanced house framing or Optimum Value Engineering – The goal of this building technique  is to reduce lumber used in framing, which reduces thermal bridging. There are a lot of strategies incorporated, including spacing wall studs up to 24 inches on center, eliminating headers in non- load-bearing walls, designing on two-foot modules to make the best use of common sheet sizes, and to reduce waste.
  3. Insulated studs – The company T Stud produces an R19 stud that is a thermally broken, insulated wall stud assembly. They also have the BareNaked Tstud™, which is an uninsulated, thermally broken wall stud that you can insulate with the insulation of your choice. These studs can not only reduce thermal bridging, but they are incredibly strong.
  4. “Alternative” Wall Assemblies – Structural Insulated Panels (SIPs) are a common alternative to stick-built construction and can help limit thermal bridging. These panels have an insulated foam core between two rigid board sheathing materials, which when installed properly, can provide a continuous air and vapor barrier. There are issues, however, including the use of foam. Bamcore makes a bamboo wall system that is an environmentally friendly, extremely high-performance option.

Understanding and managing thermal bridging is easy

In conclusion, understanding and managing thermal bridging is a must because thermal bridging happens in every home. And, if you are constructing a new building, you can take care of that very easily. If you have older construction or renovation, you can use the best insulation possible in between the base to mitigate the amount of thermal bridging happening.

The Green Cocoon suggests you monitor the health of your roof

Monitor the Health of Your Roof During the Winter

Home Maintenance Tips

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.

Why We Say, “Don’t Use Fiberglass Insulation!”

Insulation Tips

We recently got a call from a homeowner who wanted their attic insulation replaced. Their old fiberglass insulation was wet and dirty and needed to be replaced. Not only that, it had originally been installed upside down, leading to moisture problems.  We weren’t surprised by this situation as we get calls for help all the time. Our advice is to do it right the first time. That's why we say, "Don’t use fiberglass insulation!!

In cold climates fiberglass just won’t do

Fiberglass insulation is significantly cheaper than spray foam insulation, but it is also less effective, especially in extremely warm conditions. Summers in New England regularly hit above 100°F. Spray foam is more expensive, but you get your money back within five years.[1]

Used in roughly 85% of American homes, fiberglass insulation is the most common form of home insulation. Spray foam insulation has less market share, but is increasing in popularity.[2]  Why? Because it is MUCH better and you pay once. Professional installation is required for spray foam insulation, but hey, would you have the plumber fix your broken tooth?

Energy efficiency of fiberglass vs. spray foam

The composition of fiberglass insulation does not stop air from passing through it. On average, more than 30% of heat or air conditioning escapes where fiberglass insulation is installed. If poorly installed, fiberglass can also leave spaces around fixtures, allowing even more heating or cooling to escape.

Spray foam insulation fills all spaces, preventing air from escaping. It acts as an air barrier. Spray foam insulation is significantly more efficient than fiberglass and has a higher R-value.[3]

Problems with fiberglass

Incorrect installation – Failing to fill the wall cavities and compressing the batts are two of the most prevalent installation mistakes. They’re also the leading causes of poor performance, which is why some green building consultants, architects, and builders recommend other products. Their answer for total fill: cellulose.[4]

In a recent project we repaired, the insulation was originally installed incorrectly. As a matter of fact, because it was installed incorrectly, the vapor barrier (the brown paper side) couldn’t do its job – to trap moisture against the floor. The raft paper has to be facing the conditioned space, in this case the attic floor.

It’s cheap – That means that many home builders can offer it to reduce the cost of the home. But don’t be fooled. You may pay less now, but you’ll pay more later, for sure.

Rodents love it! – Rodents prefer safe, warm, and sheltered environments – making the inside of your walls and attic the ideal home. Insulation that can be found in these places can be even more inviting since it is a source of warmth for the scurrying critters. The malleability of fiberglass insulation makes it easy for a nest to be made, and insulation can be moved where ever needed. Once one nest is established and a rodent is comfortable enough, a colony of rodents can soon follow. With the displacement of materials, you could see a difference in the heating as warm air can now escape from your house in those areas.[5]

Length of life

Fiberglass insulation can last several years, but during that time it loses its effectiveness and you never have a complete seal against air flow. The level of effectiveness also depends if any moisture is present. You may need to replace this type of insulation or add to it as it settles and deteriorates over time.

Spray foam, on the other hand, can last as long as 80 years or more. It’s a much more permanent and effective option. While you’ll pay more up front, the longevity and efficiency of spray foam make it a very cost-effective option. [6]

In closing, when it comes to which is best in the spray foam insulation vs. fiberglass debate, spray foam wins, hands down. If you’re a DIYer, you may be used to installing fiberglass insulation. But if you’re looking for something that will last a lifetime, let a professional install spray foam. [7]

No Fossil Fuels Needed for Newton, Mass. Restoration Project

Projects

Newton, Mass. – The Green Cocoon, Inc. (TGC) was recently awarded an insulation project for a home in Newton, Mass. The original home, built in the early 1900s, is being fully renovated, gutted completely to the studs. Once completed, solar panels will be installed in the home and it will run on 100 percent electricity. Consequently, this house will not use any fossil fuels!

Closed cell spray foam was used on this project, specifically Gaco HFO (hydrofluoroolefin) spray foam. HFO closed cell spray foam is a reformulated version of spray polyurethane foam. But, the reformulated version has only a tiny fraction of the global warming potential of its predecessor.  HFO is a blowing agent and is an essential ingredient in spray foam insulation. It creates the tiny bubbles of trapped gas that slow the movement of heat and make foam such a good insulator with a very high R-value. But the most common blowing agent in spray polyurethane foam today, a hydrofluorocarbon, has a global warming potential (GWP) more than 1,000 times that of carbon dioxide. The newer type of blowing agent has a GWP of 1.[i]

“We have been using an eco-friendly closed cell spray foam for quite some time,” said Candace Lord, Green Cocoon Vice President. “It reduces excess waste and energy consumption in buildings by up to 50 percent while adding rigidity and strength to the structure. The R-value is over 7 per inch, and it has a greater resistance to the leakage of air and water vapor. It is a perfect vapor barrier in both summer and winter.”

The contract was awarded by Essex Restoration, a residential building and remodeling company in Wilmington, Mass. They have been working with TGC for over two years on restoration and renovation projects.

Home Builders Sacrifice Energy Efficiency by Using Cheap Insulation

Insulation Tips
CSIRO ScienceImage 2175 Installing Insulation Batts

This is a great article about why over half the new homes in the USA are insulated with fiberglass batts.

"The big problem with fiberglass is that nobody understands how to properly install it to minimize air leakage. And if they do understand how to install it, they don't want to spend the time and money doing it.

"So builders will happily keep building crappy walls that the wind can blow through because people can’t see it. They would rather sell visible performance, like windows and mechanical systems, because they can get real money for that."

Insulation Is Important Year-Round

Insulation Tips

Insulation isn't just for the winter months! Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes. In the summer, insulation keeps the walls, ceilings and floors of your home cooler, which eases the load on your air conditioner and lowers your cooling costs.
