Open Cell / Closed Cell Foam

There are many types of insulation products available. Two of the very best available are spray applied polyurethane foam also known as SPF. Typically these are categorized in either their Open Cell or Closed Cell formulation which is determined by its density. Generally any foam with density of 1.5 lb/cu/ft or greater would be considered a closed cell formulation. Anything less would be an open cell formulation.

Both of these materials have incredible insulating properties. SEE MODERN MARVELS VIDEO on our home page. We specify the use of both of these materials on a regular basis. One systemic problem we see in the industry is that many insulation contractors specify one type of foam and try and discredit the use of the others. Our approach is much different in that we believe that both open cell and closed cell have excellent qualities, but should should be strategically used for maximum performance AND value where their individual properties are appropriate.

Existing Homes/Envelope Problems

If you own or ever have owned an older home, you probably have lived with comfort and efficiency issues, at least during extremities in the weather. It could be the coldest part of the winter or the hottest part of the summer, but there is a sense that something is wrong. Problems like drafts, cool or warm rooms and floors are quite common in these homes, but are just as common in newer homes and in some cases even more due to the speed at which some homes are built. These issues may even keep you from the enjoyment or use of a whole particular space. If this is the case, you have a building 'envelope' deficiency issue that should be addressed.

Some homeowners try to solve these issues with a call to their HVAC company. They believe that if a room is cold or hot, that surely the heating and air company can fix it! The HVAC company will gladly come out and give you some relief...and a nice bill in some cases. You can see some benefit from this effort and expense, but unless the underlying problem is addressed, the REAL problem, then the problem is not truly solved. Only in solving the deficiency in the insulation will this problem be fixed.

Bonus Rooms

There are typical problem areas in homes of any age. For example, a finished room over a garage can be a significant problem. If you have one then you probably have experienced these problems. Whether it is too hot in summer or cold in the winter, it is definitely caused by a deficiency in the 'thermal envelope' of that room. There is no doubt the current FIBERGLASS insulation in the floor, walls and ceilings is showing us once again why this building material should be dismissed as an ineffective insulation material for use in today's homes. Sure, it's inexpensive upon initial installation and that is why builders used it, but is it the better investment? Is it really cheaper? NOT A CHANCE! We urge all of our insulation clients to consider the fact that "the cheapest insulation, is ACTUALLY the most expensive...and by far!"

Consider the cost of wasted energy, the cost of correcting the problem later. Consider the very durability and cost of the shortened lifecycle of your HVAC system trying to compensate for the insulation by continuous operation. Lastly, consider the cost of your comfort, is that worth anything?

We believe that once the true cost of poor insulation is acknowledged, most home owners will select spray foam insulation as their best investment.

To correct these problems later simply requires a greater investment of time, money and inconvenience than if it were simply done correctly when built.

If a room over the garage is cold in winter, it is the garage ceiling. If it is hot in summer, it is because the radiant heat from roof is super heating the sloped or flat ceilings or areas behind kneewalls. Remember, fiberglass does not stop radiant heat. This is a well documented Building Science Fact.

Most important, these poorly insulated rooms not only affect that room (although here it is more obvious) they actually affect the entire home.

Whether this is a just a spare room, play room or God forbid a master suite or nursery, our team at Spray Foam and More can make this problem go away in less than a DAY!! We have proven specifications that permanently solve this problem. Many of our client testimonies are written for this reason.

We have been identifying, specifying and repairing these fiberglass insulated homes for many years. For all these years it has been the same complaints:

"My bedroom is too cold in the winter, we can't even walk on the floor in the bathroom."

"My children sleep downstairs because it's too uncomfortable in summer."

"Our home has odors during the rainy season."

"Our second floor is always so cold in winter and very hot in the summer."

"Our HVAC system runs non-stop"
When asked how long this has gone on, many admit it has went on for years. They simply assumed it was normal for their home and learned to live with it.

" I just paid $10,000 for a brand new HVAC replacement system and we are still roasting. When I called the HVAC company back, the first thing they said is I needed to replace my insulation to trap and keep the cold air inside my house. Cold air coming into my house is escaping right up and out the attic. They said spray foam was the best at preventing this. Now my attic is foamed and my NEW HVAC system cools the house and actually shuts off and the cold air stays in my house. Every minute that big piece of electric equipment is not running I am saving on my electric bill. Now I found out that maybe if i had foamed my attic first I may not have had to have the expenseive HVAC installed this soon."

Comfort, efficiency, and safety issues should not be ignored. They should be corrected.

Should You Add Insulation or Install New HVAC System?

Should you spend your money on a better building envelope (air barrier and insulation) or on high efficiency air conditioners, heat pumps, or furnaces?

It's all stuff to help cut down your energy bills, right? True, but there's definitely a preferred order (when you have the option). Ironically, the more efficient the shell, the harder it is justify expensive high-end HVAC systems.

Here's the way to look at this.

The building envelope reduces the amount of heating and cooling your home needs.
High efficiency HVAC equipment reduces the amount of fuel you need to meet the heating and cooling needs. If your house is leaking like a sieve then your HVAC will just keep running, and running and running.
Remember you can put an HVAC system out in your backyard and it will run and also blow out hot or cool air right into the open air outside your home. Your electricy and natural gas bill will be sky high. When you call out the HVAC man and ask, "what's up"? He will say "your unit is running just fine!", the problem is you are trying to cool or heat the open out doors. You need to enclose the open sky. Well, knock me over with a feather, enclose the area, use foam as it is the higest effeciency available and Viola' you have a cool, conditioned, enclosed space where the cool air "stays in".
Do you want to keep sucking all of your hot and cold air up and out your attic? If not then address your homes building envelope. Seal up the attic and floors. Stop the "stack effect" with spray foam.

Think of your house as a basketball game. The HVAC system is your offense. The building envelope is your defense. You might have an amazing offense, but if you keep getting clobbered on defense, you're going to wear yourself out on the offensive side just trying to stay in the game. The better your defense, the less you have to rely on a high-powered offense. And you know what they say: "Offense sells tickets; Defense wins championships."

When talking about the effective use of super insulation material like spray foam, the building envelope reduces the amount of heat flow between inside and outside to such a degree that the house needs little heating and cooling energy to keep the living environment at the level you set at the thermostat.

So, as odd as it sounds, the more energy efficient the home is, the less sense it makes to put in high efficiency HVAC systems. Do as much as you can with the building envelope before you tackle the HVAC side of the equation. If you start with the heating and cooling equipment, you've probably lost the battle before you've even begun.
