Homeowners Beware: Re-Entry Times and Your Safety

Green, Insulation, Safety, Spray Foam

How safe is it to re-enter my home after installing Icynene® spray foam?

Homeowners and building managers often ask us about a product called Icynene, a liquid spray foam insulation. Icynene Inc. claims people can re-enter the building one hour after installation. We decided to investigate that claim for ourselves.

The Green Cocoon follows OSHA’s and the manufacturers’ guidelines when using spray foam insulation. Those guidelines state that re-entry should only happen 24 hours after installation has been completed.

Let’s Do Some Math

According to icynene.com, “Low VOC Icynene Classic Max and Icynene ProSeal spray foam products allow for re-entry after 1 hour and re-occupancy after 2 hours of active ventilation (at 40 ACH) following installation, allowing for minimal impact on construction schedules.”

Let’s have a look at 40 ACH (40 air changes per hour). Take a small, 2-story house that has a 24’ x 36’ footprint, which is 864 square feet. If we figure it has two stories at 8 feet tall, the basement is 8 feet tall, and the band joists are 1 foot tall, that’s an overall height of 25 feet.

Now let’s take the square footage (864 feet) times the overall height (25 feet) and you’ve got 21,600 cubic feet. When multiplied by 40 ACH, you will have to move 864,000 cubic feet of air in an hour!

If we take the cubic feet of air moved in an hour and divide it by 60 minutes, we calculate that we’ll need to move 14,400 cubic feet of air per minute. That takes some pretty big fans, but the average insulation company uses fans that move 2,500 cfm of air (like the one in the photo). That means that you have to have six of these fans running while you are spraying and you’ll need to leave them running for an hour once you finish spraying. And this is on a small house! The larger the house, the more fans you will need!

TGC regularly works on homes that would require 12 or more fans to hit the number. That is a lot of fans to purchase, set up, take down, and move around from job to job.

Safety First

Ask your contractor how many and what size fans they are planning to use if they install Icynene. We suggest you stop by the home and take a peek to make sure the contractor uses the right number of fans needed (see math above). Your safety should come first.

TGC chooses not to offer Icynene spray foam as Icynene reps are only allowed to spray Icynene. TGC is an independent spray foam insulation company, so we spray the product that we think is the greenest and safest for our customers. We don’t like to be pigeon-holed into using one product that might not be the best fit.

Before you purchase any spray foam insulation, get a second opinion from The Green Cocoon.

Summer Safety Tip: Be “Fireworks Smart”

Safety

Fireworks safety is very important now that the Fourth of July weekend is here! That means sun, fun, and fireworks! The Green Cocoon wants everyone to be safe this holiday season. Follow these guidelines from the National Council on Fireworks Safety to ensure fireworks safety.

Stats to Consider for Fireworks Safety

In 2006, an estimated 9,200 people were treated in emergency rooms for fireworks-related injuries, 36 percent of whom were under 15 years old. Children between the ages of 10 and 14 were at three times the risk of fireworks injuries than the general population. About a third of the injuries were from small firecrackers, 21 percent from bottle rockets and 20 percent from sparklers. In 2004, fireworks caused $21 million in direct property damage.

The National Safety Council advises the best way to safely enjoy this 4th of July is to watch a public fireworks display conducted by professionals. However, if fireworks are legal where you live and you decide to use them, be sure to follow these safety tips.

General Fireworks Safety Tips

Never allow young children to handle fireworks.
Older children should use fireworks only under close adult supervision.
Light fireworks outdoors in a clear area away from onlookers, houses and flammable materials.
Light one device at a time; maintain a safe distance after lighting.
Do not allow any running or horseplay while fireworks are being used.
Never ignite devices in a container.
Do not try to re-light or handle malfunctioning fireworks; douse and soak them with water and discard them safely.
Keep a bucket of water and hose nearby to fully extinguish fireworks that don’t go off or in case of fire.

“Fireworks Smart” Before, During, and After

The National Council on Fireworks Safety urges consumers to be “fireworks smart” – before, during, and after their fireworks display.

Before: Choose an open area away from spectators, homes, buildings, and dry vegetation. Use a garden hose to wet down the area before firing.
During: As each device burns out, soak it using a hose or bucket of water.
After: Place all used items in a covered, fireproof container and leave it outside and away from homes and buildings.

Special Safety Tips for Sparklers

Children under the age of 12 should not use sparklers without very close adult supervision.
Always remain standing while using sparklers.
Never hold a child in your arms while using sparklers.
Never hold or light more than one sparkler at a time.
Sparklers and bare feet can be a painful combination. Always wear closed-toe shoes when using sparklers.
Sparkler wire and stick remain hot long after the flame has gone out. Be sure to drop the spent sparklers directly into a bucket of water.
Never hand a lighted sparkler to another person. Give them the unlit sparkler and then light it.
Always stand at least 6 feet from another person while using sparklers.
Never throw sparklers.
Show children how to hold sparklers away from their body and at arm’s length.
Teach children not to wave sparklers, especially wooden stick sparklers, or run while holding sparklers.

Don’t Make These Basement Insulation Mistakes

Closed Cell, Fiberglass Batting, Insulation, Save Money, Spray Foam

Basement insulation installed incorrectly is a common contractor error. The results can be disastrous as severe mold and mildew may become a problem, not to mention the loss of money on your heating bill. Since most basements are inherently moist, you need to keep all untreated wood away from the concrete surfaces. Moisture below the slab can wick up into the concrete and get to the base plates of the wall. Therefore, you need to make certain the bottom plate of the wall is treated lumber.

Avoid Using Fiberglass Insulation in Basements

As seen in the photo above, putting polyethylene over fiberglass insulation is a no-no as it doesn’t allow the insulation to breathe. Consequently, this homeowner had moisture build-up and ultimately mold growth!

For years contractors have been treating basements much like regular living space. It’s not uncommon to see fiberglass insulation in direct contact with basement foundation walls. Here in the northeast, we see several common mistakes, including:

Plastic vapor barrier against concrete wall, fiberglass insulation inside stud wall, then drywall
Fiberglass insulation inside a “bag” hanging from the rim joist down along the foundation wall
Stud wall filled with fiberglass insulation an inch or two away from the concrete wall^[1]

Those mistakes can increase the chances for mold to grow.

What Causes Mold to Grow in Basements?

Mold can grow on virtually any organic material as long as it has the right moisture level and oxygen. Because mold eats or digests what it is growing on, it can damage a building and its furnishings. If left unchecked, mold eventually can cause structural damage to building materials and can cause health problems. That’s why we don’t want mold in our basements! Specifically, we can prevent damage to buildings and building contents in the basement areas, save money, and avoid these potential health problems by controlling moisture.

According to the EPA, indoor relative humidity in homes should be kept below 60 percent — ideally between 30 and 50 percent. ^[2] In addition to preventing mold formation, maintaining the correct humidity levels may also have a bonus effect. It may discourage pests such as cockroaches, silverfish (bristletails), and dust mites from showing up where you don’t want them!

To measure the humidity of your home or basement, you need to buy a humidity meter and track the relative humidity level. That is the first part of understanding the mold problem in your home or basement.

Education Needed

If contractors are still using fiberglass insulation in basements, it means that we in the industry need to do a better job educating our builders. In order to understand the issues with basement insulation, you first must understand the role of vapor barriers in basements.

Use the Right Insulation

Over the years, we’ve come to rely on two main approaches for basement insulation projects and remodeling, including closed cell spray foam and rigid foam board. When installed in the correct thickness, these two methods result in a proper vapor barrier and superior insulation.

Get Educated – Be the Pro!

Today, the building industry and building science are changing rapidly.

Did You Know? Insulation R-Value Changes

Closed Cell, Fiberglass Batting, R-Value, Spray Foam

In the world of building construction, improvement, and insulation, we talk about R-value all the time. Usually, we talk about it as if it’s a constant number. We see R-19 stamped right there on the product, so that’s what it is, right? Well, did you know that the R-value of insulation is not a constant?

What Is R-Value?

R-value is a measure of resistance to heat flow through a given thickness of material. R-value is important, but it’s just one of a few key factors that determine the effectiveness of an insulation material. The R-value is tested in an air-tight vacuum chamber, which means that typical insulation materials like fiberglass and cellulose do not actually perform with that value unless paired with intense air sealing measures.

^[1]

How Is R-value measured?

Because of scams involving R-value claims that didn’t match reality, the U.S. Federal Trade Commission (FTC) devised the R-value Rule to protect buyers of insulating products. In fact, in 2013 the FTC handed down its largest fine ever ($350,000) to a company claiming that its paint had an R-value of 100.^[2]

So, the R-value Rule requires testing insulation using one of four American Society of Test Methods (ASTM) standards. The basic requirement is that the mean temperature must be 75° F (24° C) with a temperature difference of 50° F (28° C) across the insulation.^[3]

According to Building Science Corporation, most R-value testing is done with a temperature of 50° F (10° C) on the cold side and 100° F (38° C) on the hot side.^[4]

The Lowdown on R-value

The main point here is that R-value isn’t some constant number for a given material, and installation isn’t the only factor that affects it. As you can see above, temperature has a significant effect as well.

The team at The Green Cocoon knows that the performance of the insulation is affected by how well it is installed. Energystar.gov has developed guidelines for grading the quality of installation. Moreover, they’ve developed a table that shows what levels of insulation are cost-effective for different climates and locations in the home.^[5]

Compression

Improperly installed insulation loses its R-value. For example, fiberglass can lose up to 50 percent of its prescribed R-value when compressed. When you compress fiberglass batt insulation, the R-value per inch goes up, but the overall R-value goes down because you have less inches or thickness of insulation.^[6]

Fear not, closed cell spray foam is the only insulation material that has an almost constant R-value. The reason is because you cannot pass air through it or compress it.

Gaco Profill Spray Foam Used on Northshore Project

Open Cell, Portfolio, Spray Foam

The Green Cocoon recently completed a project in Massachusetts and had the privilege to work with Gorman Homes. “We work with these guys quite often and they’re great,” said Jim Materkowski, The Green Cocoon President. “We used Gaco Profill in the walls to eliminate open cell shaving waste.”

The Gaco ProFill System is the first complete spray foam system to offer a consistent cavity fill and a smooth surface with no trimming needed. The self-compressing characteristic of this tough, true polyurethane based spray foam is the reason Gaco ProFill can be quickly and easily installed behind a membrane (either Gaco ProFilm or Gaco ProWeb) as part of the Gaco ProFill System. (gaco.com)

There is hardly any waste, which means the Gaco ProFill System provides higher yields than most open cell foams. Consequently, scrap disposal expenses are greatly reduced or eliminated.

Northshore Rehab

Closed Cell, Portfolio

The Green Cocoon was fortunate to work with Red Hammer Builders from Georgetown, Massachusetts on this project. The house, which is located on the northshore of Massachusetts, was built in the early 1900s.

The project is a full gut rehab, and closed cell spray foam was applied throughout the building.

As you can see, everyone is wearing protective equipment to protect you and themselves from Covid-19 AND the insulation!

Earth Day Goes Digital During Covid-19 Pandemic

Environment

Even though many of us at The Green Cocoon are working from home just like you amidst the Covid-19 pandemic, we can still do our part on Earth Day 2020 (EARTHRISE).

From the 2020 NCAA Basketball Tournament in the U.S. to the UEFA Champions League and Europa League in Europe to the Grand Prix in Australia, just about every big spring event this year has been cancelled or postponed. But the annual event coming up on April 22, Earth Day, will be held rain or shine. You don’t want to miss it!

Earth Day History

This year is the 50th anniversary of Earth Day, which began as a “youthquake” in 1970 with former Wisconsin Senator Gaylord Nelson leading the charge.

Here’s a little history: On April 22, 1970, millions of people took to the streets to protest the negative impacts of 150 years of industrial development. In the U.S. and around the world, smog was becoming deadly and evidence was growing that pollution led to developmental delays in children. Biodiversity was in decline as a result of the heavy use of pesticides and other pollutants. The global ecological awareness was growing, and the U.S. Congress and President Nixon responded quickly. In July of the same year, they created the Environmental Protection Agenc. They also created robust environmental laws such as the Clean Water Act and the Endangered Species Act, among many. Earth Day is now a global event each year, and more than 1 billion people in 192 countries now take part in what is the largest civic-focused day of action in the world.

EARTHRISE: Earth Day Goes Digital

The theme for this year’s Earth Day is Climate Action. Earthday.org states, “Climate change represents the biggest challenge to the future of humanity and the life-support systems that make our world habitable.” With the coronavirus wreaking havoc on us all and limiting our activities, Earth Day organizers had to get creative.

In a recent press release, Earth Day Network noted that they are shifting their actions from massive worldwide cleanups to a strictly online campaign. The title of their movement is EARTHRISE, which is a “global, digital mobilization that drives actions big and small, gives diverse voices a platform and demands bold action for people and planet.” Over the course of 24 hours, EARTHRISE will fill the digital landscape with global conversations, calls to action, performances, video teach-ins, and more. Learn more.

Some people have already started recruiting others to do their part by hosting Facebook events. For example, Amanda Merlino from Florida is hosting a “Get Trashed for Earth Day” event on April 19^th. She is encouraging people to grab “a plastic bag, wear some gloves, and pick up all of the discarded trash that you see. Post pictures or video of your efforts to encourage others to get involved.”

How to Celebrate Earth Day at Home

While none of us are sure how long this pandemic will last, each of us can take steps to ensure we don’t turn one crisis into another. Strive for sufficiency over efficiency, avoid the urge to panic-buy and learn how to cook for a few days with what you have in the house, rather than run to the store for one item.

Take a walk and pick up trash

Whether you walk by yourself and pick up trash or you recruit others to do it, seeing a clean street shows pride for one’s town or city. Join an event like Amanda is holding or hold one yourself. Doing something with others increases one’s motivation.

Cut way back on water

Since you’re not going out, consider cutting back on showering to save water and energy (but keep washing your hands!). Unless you’re in direct contact with medical professionals or constantly out in the world, try showering several times a week instead of every day.

Embrace frugality

Try eating the same breakfast every day for a week. Keep your pantry stocked with humble ingredients that are also delicious. Now is a great time to pass your frugal life skills onto your kids. Breakfast is important!

Let your yard go wild

Treehugger.com says to “Turn your lawn back into a productive plant community. Plant clover. Stop raking your damn leaves and use them as a home compost pile instead. Grow vegetables in your yard. Plant a wildlife hedge instead of building a fence.”

Stay healthy

Help overworked healthcare professionals and hospitals by keeping your own immune system strong. Go on a walk for both a mental and physical break. If you’re unable to go outside, try one of these “visual soundscape” videos to relax. Reduce your consumption of meat and dairy.

In summary, all of us working together can save the planet. We just need to get along. Stay healthy and strong this Earth Day. Learn more about Earth Day.

The Green Cocoon Is an “Essential Business” and Will Remain Open

Covid-19

The Governors of Massa chu setts and New H am pshire have asked all non-essential businesses to close. The Green Cocoon (TGC) is excited to be listed as an essential business, and thus will continue working on all projects as planned, unless other arrangements are made.

Employees Working From Home

All office employees are now working from home and only the installers are coming to the shop. They get the supplies they need and then head off to the project site.

Taking Extra Precautions

“We are a very small crew and are taking extra precautions in the office by deep cleaning surfaces frequently,” said Vice President Candace Lord. “By law our installers have to wear respirators while at the job site, so they are already better protected from the virus. Moreover, TGC uses mechanical ventilation while we work, which creates a negative pressure in the house. This actually prevents any of our air from getting into your house!”

If you have any questions about your current project or would like a consultation for something new, please contact us. Stay safe and healthy everyone.

The Coronavirus and Your Safety

Covid-19

At The Green Cocoon, the safety and well-being of our employees and our customers is always our priority. We are actively monitoring the Coronavirus (COVID-19) situation and taking steps to help keep our employees and customers safe. We wanted to share with you some steps we are taking.

Protecting our employees and customers

As our employees interact with customers and the general public, we have taken steps to limit exposure to the virus.

Employees

The Green Cocoon has 12 employees, so we are a small, but mighty group. We are postponing our team meetings, providing remote-work solutions, and continue to reinforce safe behavior in every environment—from customer homes and businesses to our offices. We are in continuous communication with our employees reminding them about the importance of good hygiene, providing them with health education and support whenever needed. Employees who feel ill have been told to not report to work.

Customers

When we first meet you, The Green Cocoon sends one sales person to your home. They have washed their hands and sanitized their vehicles before coming into your home. Once we are hired by you, we send a crew of two people to perform the actual work. Safety regulations mandate that homeowners be absent from the home while insulation is being installed. And, our employees must wear a protective suit, thus limiting your and their exposure while they are in your home.

If you have any questions, please contact us. We are open for business!
