In Green Graphic Design author Brian Dougherty asks graphic designers to start at the end of the process instead of the beginning. In Cradle to Cradle: Remaking the Way We Make Things authors William McDonough and Michael Braungart make a similar case for how sustainable practices need to be implemented. One of the biggest challenges that graphic designers face is educating their clients about sustainable practices.
Get the Guide Ethics: A Graphic Designer's Field Guide is a 60 page handbook that looks at the ethical issues graphic designers face along with case studies. The first rule with spray foam is “hire the installer spraying the foam, not the foam manufacturer or the foam brand.” By this I mean, the installer’s brain is the most valuable asset in selecting who will do the job. I was reminded of this a few weeks back when I visited a job site with terribly applied spray foam. When the two liquid components of spray foam come together, there is a very rapid exothermic (heat-producing) chemical reaction. In this core, the color changes from a greenish hue at the base to a more yellow, toffee color at the top. This spray foam core sample had a uniform cell structure (small bubbles) and was consistent in color throughout. Note to self: With each layer of foam applied, defects get amplified, resulting in a bumpier finish. Blisters or voids are caused by a number of things — including electrical wires, plumbing pipes, framing that creates shadows in the foam, poor access in a tight space, or just spraying over a messy area. A good sprayer also will appreciate the fact that spray foam won’t stick to 6-mil polyethylene. The red marker indicates places where we found air leakage passing through the newly installed spray foam. The difference between the two is that one may be spray-foamed directly, while spraying the other one may cause the pot light to overheat and should be considered a very serious fire hazard. The moral of this tale: if you invest in spray foam, hire a good installer, And if the foam is part of the air barrier system, test it for air leakage. Great article; however, I'd like to offer a word of caution about directly encapsulating recessed can lights without providing necessary clearances. To be clear, the NEMA and SPFA study did NOT find a combustion hazard from encapsulating IC rated cans. Expanding foam can also cause a second unacceptable condition with recessed lighting fixtures and their associated junction boxes.
Then why do the first two insulation quotes I've received specify closed cell foam down the walls to seal with the poly vapor barrier?
To limit the flow of water vapor through your basement walls, either rigid foam or closed-cell spray foam is effective. Thanks for the reference, I totally agree about foam being pushed in through the stamped, metal box and I also feel uneasy about the foam directly against even IC rated boxes. I suspect if the poly is clamped and air sealed to a framing member and that enough of that framing member is exposed to the new spray foam for good adhesion you might be able to get a satisfactory seal. It should be noted the above was all part of a renovation to eliminate ice dams and it should be noted that retrofitting spray foam is a more complex job than new construction. I shoudl have started off the article by saying all insulation types can be badly installed.When done properly though, spray foam is a wonderful insulation with the caveat that it has a lot of embodied energy. And the caveat that at the end of the building's life that spray foam will probably be a liability. Over the last year I watched a large local high school being demolished, the components sorted and recycled right down to the door and window hardware being stored for replacement parts for other buildings and crushing the concrete foundation for aggregate. As I told Malcolm, I'm glad to hear that there are regions of North America where salvage is routine.
The main barrier to salvage is that (in many cases) the labor cost to remove fasteners is higher than the value of the salvaged material.
Martin, is the labour cost to remove fasteners higher than the value of the salvaged material, or are the environmental and labour and embodied energy costs of new materials higher than that? The new Heat & Eat meal pots range features six products, each containing 300 calories per pack.


They are presented in bright packaging, boldly highlighting the calorie count and ingredients. The meal pot range has been developed over a 12-month period and is manufactured and retailed under licence by Kerry Foods. The range was initially launched in the foodservice sector, where sales are forecast to exceed ?2m in 2012.
The launch with Sainsbury’s is the first step in a programme to expand the retail sector reach of the Tasty Little Numbers brand. Initial products included 100 calorie chocolate bars and crisps and 200 calorie snack pots. Beach said: “We have received amazing feedback for Tasty Little Numbers from both retailers and consumers. When creating traditional print materials the toxicity of ink and paper and the sheer quantity of paper produced need to be considered.
Imagine the best possible destiny for your design and visualize the process of every phase from the final destination of your product at the end of its life cycle back to the design studio.
They assert that it’s not enough for us to “reduce, reuse, and recycle.” They explain how products need to be designed from the outset so that after their lives they will provide nourishment for something new. When companies claim to be ecofriendly based on a myopic view of sustainability and without looking at all the implications of their actions, they may end up being guilty of greenwashing—the practice of “spinning” their products and policies as environmentally friendly, such as by presenting cost cuts as reductions in use of resources. This core was taken from a layer of foam that had been applied 6 inches thick in a single pass. Sick because this high-performance insulation has a big carbon footprintAmount of carbon dioxide and other greenhouse gases that a person, community, industry, or other entity contributes to the atmosphere through energy use, transportation, and other means. When it’s not installed correctly, it can get expensive for the client, the contractor, and the planet. The rigid foam that you buy at the big box store is produced in a highly controlled factory setting to exacting, repeatable standards and is tested for quality before it leaves the factory.
It had every problem you could imagine: fire hazards created by the spray foam, charred foam, air leakage through the newly installed spray foam and missing foam.
As a rule of thumb, most 2-pound spray foam or medium-density spray foam should be installed in layers no more than 2 inches thick. We want the foam to be applied in even coat(s) on a solid, clean and uniform substrate the foam can stick to. So don’t expect a durable air seal if you are using polyethylene as your air barrierBuilding assembly components that work as a system to restrict air flow through the building envelope. Wires, pipes and framing will cause “shadows” in the foam as it’s projected out the gun, much like a flashlight will cause shadows in the dark.
Some recessed can lights are encased in a metal box that’s IC (insulation contact) rated, as this one is.
Either way, if the pot light is installed through your air barrier, it’s going to leak air. As the foam expands, it can intrude into the crevices and small openings inherent with this type of equipment. Because polyurethane foam can exert significant force as it expands, any blocking mechanism must be sturdy enough to resist the resulting forces.
It further confirms my decision to never recommend spray foam, it really seems to be too difficult to get a satisfactory result. To the extent that spray foam may overlap the crack between the slab and the wall, it will certainly reduce air leakage at that crack, which is a good thing. There is no building science justification for worrying about tying that sub-slab vapor barrier to a wall vapor barrier. Since closed-cell spray foam is already a vapor barrier, there is no need to install polyethylene on a wall insulated with closed-cell spray foam -- and in fact installing polyethylene on such a wall is not recommended. You could also try a "transition strip" by testing foam's adhesion to different approved air barrier tapes? I struggle with this last point, especially for vintage masonry buildings where spray foam seems to work fairly well. I imagine society will be apalled at the sight of the building being trashed because we can't recycle the components of the exterior walls.


Our basement has a dirt floor and the quotes have called for everything from 6mil poly to EPDM to pouring a slab, all with foam on the walls that would "seal" the specified membrane.
For example, the high-end builder where I am buys up every stick of salvaged lumber and timber he can get, has it remilled and uses it for finishing. My house includes beams and hardwood flooring that I salvaged in the 1970s from homes slated for demolition. When it comes to re-milling old lumber, most millwork shops would rather see a little bit of adhered spray foam than a nail or screw.
Tasty Little Numbers is not a diet brand, it is created to be the life and soul of the health-conscious party, a brand which says, “I am fun and I care enough about myself to enjoy a balanced healthy diet with products which suit my personality”.
In addition to these factors there are other phases of the life cycle of products that need to be examined. Consider everything from the time of its ultimate disposal to its conception including transportation, warehousing, production, and manufacturing that may prevent green solutions from being implemented. McDonough and Braungart feel that when designers employ the intelligence of natural systems—the effectiveness of nutrient cycling, the abundance of the sun’s energy—they can create products and systems that allow nature and commerce to fruitfully co-exist. Spray foam, on the other hand, is manufactured on the job site, so we’re banking on the person pulling the application gun's trigger to know some foam chemistry and building science. Experienced sprayers who know the behavior of the product can repeatedly get the foam to cure in a nice even coat. IC rated fixtures are also equipped with a thermal protection device that turns off the lamp if the housing temperature exceeds prescribed limits. After the foam hardens in these internal spaces, it can degrade the functionality of the luminaire, prevent routine maintenance as well as prevent inspection of and access to critical electrical connections.
But my main concern is that foam renders all the materials it touches unrecyclable and that alone should make this product unacceptable and banned from the construction industry. To make sure that the air barrier is continuous, the usual advice is to caulk the crack between the slab and the wall. In spite of this "appalling" fact, I note a decided lack of protestors or weeping onlookers. Watching the school be sorted and disappear from its very prominent site on a main road was an eye-opener for many of us. We're leaning towards the slab though we have little interest in using spray foam anywhere in the building other than in small amounts to seal cracks, etc.
Removing every last fastener isn't a simple task, especially when the nails were driven by a nail gun. To really determine the sustainability or carbon footprint of a product, one needs to follow it through its entire life cycle.
The color at the base of the core is a greenish hue — not a healthy sign — and the foam had a strong smell even after curing for two weeks. That's a rare combination, made rarer still if we expect that person to lay a lot of foam down quickly, cleanly, and uniformly.
In the video above, I'm talking with Mike Cerqua of CallRich Eco Services, our go-to expert spray foamer who was called in to clean up this job. As well, there's an outfit called Demex that stocks used construction components, especially windows and doors.
What millwork shop is going to remill lumber that has foam on it that may be hiding metal fasteners?
Questions need to be raised about how much fuel is being used for shipping, what the final end product is, how long the life cycle is, and how long before the product ends up as waste. Anywho, I sure hope you're wrong Martin about it taking fifty years to see a change in attitudes around this.
