Why Attics Need to “Breathe” Year Round – A True Story

Recently I met a man who used to work in the construction business. More specifically, he worked in a niche as a construction “fixer.” His job was to go to newer developments where homeowners had various complaints or problems with their houses, narrow down the issues, itemize them, quote the price to fix the problems, and assist the homeowners by trying to work out solutions with the original developer who built the homes. His story applies to all homes, but I found it ironic that he was experiencing this in newer homes.

While out on a call to a home in winter, he entered the homeowner’s master bedroom. He saw black streaks on the ceiling. He pointed them out to the homeowner and asked if they could take a look in the attic. The homeowner seemed surprised by this and asked him why. My friend said, “Do you know what those streaks of black are on the ceiling?” The homeowner was puzzled and had no idea. My friend said, “That’s mold growing on your ceiling, and I guarantee you that your attic is wet.”

They went up to the attic, icicles were hanging from the attic ceiling, and, sure enough, the attic was also wet. The culprit? There was no ventilation in the attic. It might be hard to believe that icicles can form inside the house, but in many older homes that lack proper insulation and ventilation, the attic can become a magnet for condensation, which will freeze when it gets cold enough and the moisture has nowhere to go. … After a while, this frost builds up to form icicles. Homeowners assume that attic fans are only useful in the summer to move the heat around and keep the attic and home cooler. This could not be further from the truth. While fan ventilation does the trick in summer with the correct type of fan and the fan’s correct placement, it is just as important in winter. In the winter, heat in your home rises – to the attic. With it comes moisture. When attics are not well ventilated, moisture collects in this area of the home. … Adequate attic ventilation allows cool, dry air from outside to come into the attic, while warm, moist air inside the attic can escape.

Attics and More sells solar attic fans that have a lifetime guarantee. They install quickly and are workhorses without tapping into your electrical grid. Some other facts about our fans:

  • They can withstand 150 mph hurricane winds
  • They can withstand golf ball-sized hail
  • We offer a lifetime warranty
  • The flanges are made of a single piece of aircraft quality aluminum
  • They are made in the USA
  • The motor is completely sealed, which means that no dust or moisture can get inside causing the motor to seize and potentially creating a fire hazard
  • They are whisper quiet

Our price not only includes the installation of the new solar fan but the removal of another fan if you have an existing one. Our solar fans also qualify for the federal solar tax credit (26% for year ending 12/31/2020), and we provide the paperwork to you. This credit steadily declines each subsequent year, so it really is in your best interest to purchase a fan now. Our fans are not made in China like those sold in the big box stores, and ours come with a lifetime warranty that cannot be matched.

If you have not had the opportunity to see or have one installed over the hot summer months, now is the time to contact us for a complimentary appointment to see our fans at your home up close and personal, AND take advantage of the highest federal solar tax credit. Let our Attic Specialist stop by to recommend the fan that would best suit your attic based on square footage and roof pitch, so give us a call today at 856-474-2400!

Insulation Dangers: Closed Cell/Spray Foam vs. Blown-in Fiberglass

Most homeowners never consider what kind of chemicals are literally over their heads. And by chemicals, we mean attic insulation material.

There’s a myriad of choices when it comes to insulation. What most customers don’t know, however, is that several types of insulation may contain hazardous material that can fuel long-term health problems.

For the sake of space, we’re going to place two types of insulation under our “blog microscope” (blog-oscope?) – Closed Cell/Spray Foam and Blown-in Fiberglass. Spoiler alert: blown-in fiberglass turns out to be safer AND more energy efficient.

Danger Above: Spray Polyurethane Foam

Spray Polyurethane Foam (SPF), as the name implies, is, well, spray foam composed of polyurethane. SPF’s are classified as high, medium, or low density. Attic insulation falls into medium or low. Medium-density SPF’s are sometimes called “closed-cell foam” because they are contained within an internal closed-shell configuration to improve thermal resistance. To make this simple: All closed-cell foam is SPF but not all SPF is closed-cell.

SPF has been a popular attic insulation choice because of its high R-value. Readers may recall the term from previous posts. EnergyStar defines R-value as “a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value, the better the thermal performance of the insulation.”

Sounds great, right? Well, here’s the problem. SPF contains a harmful chemical scarily named
isocyanates. Now, if isocyanates stay locked inside the insulation, it’s probably not an issue.

However, the EPA notes: “If SPF was not applied properly, chemical contaminants may have migrated to hard and/or soft surfaces elsewhere in the building and may be the source of residual odors; therefore, removal may not resolve the issue.”

Think about your attic for a moment:

• What do you know about the composition of your attic insulation?
• Was it installed before you bought the home?
• What were the qualifications of the installer?
• Why do you have 5 years’ worth of magazines up there?

It’s likely the answers are “Not much,” “No idea,” “Dunno who installed, “Hey, those special editions of Good Housekeeping will only increase in value!” Therefore, most homeowners have no way of knowing if they have SPF or if it has been properly installed and, as such, don’t know if isocyanates have seeped out. Yikes!

What’s the worst that can happen if your attic is a ticking isocyanate time bomb? Let’s ask OSHA:

“Health effects of isocyanate exposure include irritation of skin and mucous membranes, chest tightness, and difficult breathing. Isocyanates include compounds classified as potential human carcinogens and known to cause cancer in animals. The main effects of hazardous exposures are occupational asthma and other lung problems, as well as irritation of the eyes, nose, throat, and skin.”

According to Metropolitan Engineering Consulting and Forensics:

“We do know for sure that the prevalence of asthma in the overall United States population has
increased by almost 100 percent since the early 1980’s and links have been reported between these foams and the asthma or dermatitis incidents. A study that was done by Krone, et al. and published in the publication Environmental Contamination and Toxicology in 2003 showed that isocyanates in foam containing consumer products were present 30 years post-manufacture.”

Stay Safe with Blown-in Fiberglass

Commonly composed of fiberglass or cellulose, blown-in insulation is (surprise) blown into attic spaces like confetti. The tiny particles seep snugly into any space and can fill existing walls with minimal damage to any desired depth.

Of course, no insulation type is 100-percent without potential health risks. However, blown-in fiberglass offers maximum benefit with minimum risk – especially when installed by a qualified pro.

  • Blown-in insulation keeps indoor attic temperatures cooler in summer. In addition, blown-in stops heated and cooled air from leaking out. Since it fits into the smallest spaces, blown-in maximizes HVAC performance. Consumers report blown-in insulation often saves so much in energy costs that installation pays for itself in a couple of years.
  • Blown-in fiberglass insulation also reduces the risk of fire. Since it creates a tight seal across the attic, air can’t flow through small spaces to stoke a blaze.
  • Blown-in is easy to install quickly by a qualified installation team – often within a few hours.
  • Because blown-in creates such a tight seal, overall household noise is reduced. And, in these trying times when we’re stuck at home, a quiet home is a peaceful home.

Choose Wisely: The Right Pro for the Job

If you’re convinced that perhaps your attic needs some attention, the first step is an inspection. Attics and More offers a free attic inspection to determine if you have the safest and most efficient attic insulation, as well as uncovering other trouble spots. If blown-in installation is the best option, we’ve got you covered.

EnergyStar notes: “It is easier to get complete coverage of the attic floor with blown-in loose-fill insulation. It is best to hire an insulation contractor for this job.

My Grandmother’s Attic

When’s the last time you went into your attic? I did not give my attic much thought until I started a new job. Now I am amazed to discover how rare people go in their attics. I have talked with homeowners who have not been in their attic for 20+ years.  One new homeowner said that she purchased a home 8 months ago and has actually never been in her attic.

Here’s my attic story:

When I was a little girl, I remember seeing magic attic stairs pop down from the ceiling in one of my grandmother’s bedrooms in her tiny rancher. Kids who see stairs always wonder what’s on the other end. I was so small and the stairs so large that I never went beyond just looking up.

As I got older and saw those stairs descend each Christmas to bring down decorations, I would beg my mother to allow me to go up. It was always a firm “no,” and I lived with it.

After my grandmother passed away, I was at the house with my mother and my aunt. We were packing up boxes and reminiscing. I walked into the spare bedroom, where I saw the stairs to the attic had been pulled down. I was 32, and I had my own attic with pull-down stairs by that time. But the lure remained. I HAD to see what was up there. My aunt heard me step up the first three rungs and yelled out, “Don’t go up there! It’s full of asbestos!” As I am apt to do, I said okay and went up anyway, but stealthily and quickly. It was gross. “Stuff” hung from the rafters, my eyes burned, I couldn’t breathe, and it felt like I was inhaling particles.

A dirty attic with poor insulation, similar to what was in my grandmother’s home.

But I did see my Fisher-Price castle with the working castle gate. I ran and snatched it like a thief in the night. The Lincoln Logs were covered in the debris that was hanging everywhere. On the floor, I saw what polite people would not refer to as “rodent turds,” but it most assuredly was. I ran to the kitchen with my castle and washed it off while my aunt looked at me unfavorably and told me that I should not be handling something covered with asbestos. Plus, I hadn’t listened to her and went up in the first place. She was right, of course.

It ended up that my aunt had specialists come out in hazmat suits and respirators to remove the toxic material in my grandmother’s attic and had it replaced with safe insulation. The lesson that I learned is that if you don’t know what’s in your attic, it can hurt you. I also learned that if you are pigheaded enough to ignore the pleas of your aunt and mother to stay out of an attic, you can score a childhood toy, but at what cost?

I’ll end this by saying: Know what’s in your attic. If you don’t know or don’t want to know, hire a professional to do this for you. Attics and More will provide a free complimentary home energy analysis, which includes inspection of your attic and crawlspace.

As for my Fisher-Price castle? It’s now safely inside my attic. I feel content, and some redemption, knowing it’s there.
