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]

The United States demand for insulation is estimated to rise 3.7 percent per year to approximately $9.5 billion by 2021.^[i] And with so much demand, new types of insulation are being tested for the future. We will focus on one—Hemp.

According to Green Building Advisor, “Two North American companies are producing insulation for residential construction from locally sourced hemp fiber. This gives builders an alternative to fiberglass, plastic foams, and other more conventional materials.”^[ii]

Europe Has More Access to Hemp

In Europe, builders have access to hemp insulation, but availability has been limited in the U.S.  Some U.S. builders have toyed with a mix of hemp fibers and lime called “hempcrete.” But, because of U.S. laws, extensive use of industrial hemp has been blocked.

One Canadian company capable of producing threadlike hemp insulation on a commercial scale is Montreal-based MEM Inc.  Not far behind producing hemp fiber insulation is a biomaterials supplier in Louisville, Kentucky, called Sunstrand. And, new on the scene is Nature Fibres, a Canadian company based in Quebec. ^[iii] The interesting fact about Nature Fibres is they moved into Asbestos, Quebec, to start up their business. The town was named after asbestos because of the former industry in town. But, due to the associated health risks, those manufacturing facilities are closing their doors.

Benefits of Using Hemp

The benefits of using Hemp for insulation are many. It is biodegradable and has a very long service life. “Walls opened up in France 50 years after construction showed hemp insulation looking essentially brand new.” Hemp is composed mostly of a natural fiber (88% hemp fiber and 12% polyester fiber) with no chemical binders and no VOC (volatile organic compounds) off-gassing. As a result, it allows water vapor to pass through it. and is naturally repellant to rodents and insects.

It is clear that with all the changes in the market and with regulations, the insulation industry needs to keep up with demand and changing times. The Green Cocoon is a company that looks to help people lower their carbon footprint by increasing their home's efficiency. We do this while using the greenest products available on the market.

Building a new home comes with a myriad of decisions: How many bedrooms? Do you need a big garage? What about your landscaping? One of the easiest decisions to make is to build sustainably.

Sustainable homes are beneficial for both homeowners and the environment. This is due to the energy efficient design process and green building practices. Read on to see six of the most popular sustainable home trends. Learn how they can improve your quality of life.

Passive Building Design

The word “passive” in this instance means that Mother Nature is doing all the work to maximize natural resources. This allows you to minimize energy consumption.

Instead of a design that uses technology like boilers and electric lighting, the internal environment in a passive home is powered by external elements. These include solar radiation, air pressure variations and outdoor temperatures. Passive homes will help restrict heat loss in the winter and reduce heat increases in the summer.

One of the most common features of a passive home is a large overhang as part of the roof. This helps shade windows in hot weather and prevent water from entering.

Use Sustainable Building Materials

Quality, reusable materials are sent to landfills every day. Sustainable building companies reclaim and repurpose them for use in homes.

Recycled materials typically include tile, flooring, reclaimed wood, roofing materials, light fixtures, steel and many others. Homes often incorporate these items for décor purposes too, like recycled barnboard to create an accent wall.

Sourcing for sustainable and recycled products can take longer than new materials. There may also be added costs. But by preserving these materials, you’re making what was once old new again and helping to limit waste. There are many salvage companies that collect spectacular items from homes that are being renovated or demolished. It can be an exciting challenge to hunt for a treasured vintage item.

Prefabricated Homes

A prefabricated home is another great way to limit waste. These houses are built at an off-site location. Building off-site makes the production process more efficient than building right on your lot.

Your site can be prepared at the same time your home is being built.

There are also hybrid processes. This is where parts of your home are prefabricated, while the rest is constructed on site. One of the most popular techniques is a panelized wall system. The walls are constructed off-site. Upon completion, they are delivered to the lot and assembled like a puzzle.

Green-Certified Homes

You can design and build a home with sustainability in mind. But, receiving a certification will really legitimize all of your hard work.

ENERGY STAR certifications are one of the highest a building can receive. To become certified, a home must meet the strict energy performance standards put in place by the Environmental Protection Agency (EPA). ENERGY STAR homes not only help protect the environment by emitting less greenhouse gas. They also help homeowners save energy and costs while creating an incredibly comfortable home, with fewer temperature fluctuations and greater sound control. In just 2017, ENERGY STAR buildings helped families and businesses save $30 billion in energy costs!

There are also LEED certifications, Leadership in Energy and Environmental Design. These set a standard for the design, construction and operation of high-performance homes and buildings. LEED has various rating levels, depending on how many points a home scores in terms of efficiency. These homes use less water and energy, reduce waste and enhance indoor air quality.

Use Non-Toxic Materials

Many materials found in homes contain hazardous chemicals and toxins that can be harmful to both homeowners and the planet.

Many glues, paint, adhesives, coatings and other materials contain volatile organic compounds (VOCs). These can enter the atmosphere of your home and travel outside. Formaldehyde is one chemical that’s commonly found in paints and solvents. It can cause allergic reactions, irritations and even trigger an asthma attack when it off-gases.

For a non-toxic, healthy home, opt for PVC alternatives, non-toxic wood and natural insulation materials. There are formaldehyde-free products available, along with zero or low VOC paints, and cellulose, for an eco-friendly insulation material.

Net-Zero Homes

In a net-zero home, you produce the same amount of energy that you consume. These homes are built to very high standards in order to produce the most comfortable temperatures and cleaner air with reduced allergens and toxins.

Net-zero homes require sophisticated design and build practices to ensure that the structure is airtight and well insulated. They also need solar panels to generate enough energy to power to your home.

The initial construction will likely run higher than the average cost to build a new home. However. you will be able to save by not having to pay monthly energy bills well into the future.

Once you’ve moved into your sustainable, eco-friendly home, don’t forget to incorporate green décor! Certain indoor plants, like Dracaenas, snake plants and Boston ferns, help purify the air and reduce VOCs. You can also continue to explore salvage options for your furnishings. The items that you select will come with their own historical relevance. The environment will appreciate it.

If insomnia is a problem, maybe your bedroom is too hot or too cold. Both can affect sleep in surprising ways.  Are you keeping your room too cool for comfort because your home costs a fortune to heat? Don't lose sleep to save money! Contact us to find out how you can make your home more energy and cost-efficient.

How Air Temperature Affects Your Sleep

Experts agree the temperature of your sleeping area and how comfortable you feel in it affect how well and how long you snooze. Why? “When you go to sleep, your set point for body temperature -- the temperature your brain is trying to achieve -- goes down." "Think of it as the internal thermostat.” If it’s too cold or too hot, the body struggles to achieve this set point. That mild drop in body temperature induces sleep. Generally, Heller says,“if you are in a cooler [rather than too-warm] room, it is easier for that to happen.” But if the room becomes uncomfortably hot or cold, you are more likely to wake up. He explains that the comfort level of your bedroom temperature also especially affects the quality of REM (rapid eye movement) sleep, the stage in which you dream.

What’s the Best Temperature for Sleeping?

Recommending a specific range is difficult because what is comfortable for one person isn’t for another. While a typical recommendation is to keep the room between 65 and 72 degrees Fahrenheit, Heller advises setting the temperature at a comfortable level, whatever that means to the sleeper. There are other strategies for creating ideal sleeping conditions, too. Experts from the American Academy of Sleep Medicine, for instance, advise thinking of a bedroom as a cave: It should be cool, quiet, and dark. (Bats follow this logic and are champion sleepers, getting in 16 hours a day.) Be wary of memory foam pillows, which feel good because they conform closely to your body shape -- but may make you too hot. And put socks on your feet, as cold feet, in particular, can be very disruptive to sleep.

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."
