THE THERMAL ENVELOPE
Standard residential and commercial construction has traditionally designed vented attics without regard for regional and climatic conditions.  Also, many vented attics are not designed and constructed in accordance with properly proportioned eave and ridge venting.  This can accentuate the problem of extreme attic conditions.  In warm, humid climates, attic temperatures can reach well in excess of 120 degrees Fahrenheit.  This, coupled with the infiltration of moisture laden air and attic pressurization, can cause a myriad of problems for energy efficiency, indoor air quality, condensation and comfort.  An attic cannot be vented enough to minimize these conditions.  Attic fans can cause exfiltration problems and negative air pressures in the envelope.  The ambient outdoor conditions would be preferable to the extreme attic conditions that are created.

The Thermal Envelope utilizes an unvented (sealed) attic design that places the insulation at the roof plane in lieu of at the ceiling.  Thereby bringing the entire building envelope within the thermal and air barrier.  Research has proven that there are many benefits to this method.  By locating the thermal and moisture barriers at the same plane, it eliminates the opportunity for moisture to enter the attic and condense on cold mechanical systems.  Moisture will not condense within spray foam insulation making it the ideal material for this application.

The Florida Solar Energy Center (www.fsec.ucf.edu) attributes 65% of the infiltration in the average Florida home to the attic.  This, coupled with duct leakage, can place an insurmountable burden on the mechanical systems to maintain indoor air quality and occupant comfort.  Frequently, the result is a "sick building or home,"leading to occupant illness.  There are many contributing factors; however, the most significant element is the failure of the building envelope.  If we first address how we correctly build the "closed box,"we can then better engineer the mechanical systems within that "box."

The building envelope has long been overlooked and addressed uniformly in different hygro-thermal zones. We no longer ignore that climatic conditions greatly effect how we should build the "box."  The latest research has led to newly applied perspectives in Building Science (www.buildingscience.com), primarily the Thermal Envelope.  The 1997 ASHRAE Handbook (23.10) recognizes and endorses this procedure stating, "because the net benefits of attic venting do not always clearly outweigh the disadvantages, venting should not be required in a warm humid climate."  The 2002 Florida Energy Code also prescribes Thermal Envelopes for commercial buildings.  The same techniques are being applied to residential buildings with complete success.

The Thermal Envelope alone can remedy many of the symptoms ailing "sick buildings" in southern climates.  A necessary step in the "cure" is that we must change the environment.  "Fix-it" or "Band-Aid" approaches are only a temporary solution putting the problem off to reoccur another day.  Generally condensation, duct sweating, infiltration, humidity control and bacteriological growths within building envelopes vanish when remediated with a foam-sealed Thermal Envelope.

The spray foam insulation method is the most comprehensive solution to address the remediation of a building envelope.  The diverse application techniques and the inherent properties of Foam allow it to accomplish the most difficult and otherwise impractical sealing and insulting jobs with assured success.  A Thermal Envelope sealed with semi-rigid foam allows control of humidity levels within the 45-50% range, a level at which molds, mildew, dust mites and many allergens perish -- immediately affording the occupants maximum indoor air quality.  The system also improves the thermal comfort within the entire envelope and vastly improves energy efficiency.  The sum of the results is clean, comfortable, healthy, energy efficient, sustainable construction; that not only is a Lifetime Warranted product itself, but also extends the life of the building envelope and the systems within it.

Warm Climates - A unique insulating challenge with a unique solution

To vent, or not to vent?
In warm, humid climates, temperatures in vented attics can reach well in excess of 120 degrees Fahrenheit.  With the infiltration of moisture laden air from outside and attic pressurization, a myriad of problems are created including low energy efficiency, poor indoor air quality and condensation, all of which result in a lower level of occupant comfort and even "sick building syndrome."

The Florida Solar Energy Center (www.fsec.ucf.edu.com) attributes 65% of infiltration in the average Florida home to the vented  attic design (a design which is well suited to northern climates).  Coupled with duct leakage, this places a considerable burden on mechanical systems to maintain indoor comfort (humidity levels and consistent temperature) resulting in higher energy usage, lower indoor air quality, shorter lifespan of buildings and mechanicals. 

The solution is simple.  An unvented (sealed) attic design using ZipFoam spray foam insulation at the roof plane rather than on the ceiling creates a completely closed structure.  This prevents moisture from entering the attic and condensing.  The result is a completely enclosed, air-tight, sealed building that offers healthier indoor air quality, considerable energy savings and additional storage space due to the lack of extreme attic temperatures.   Coupled with duct-sealing, the unvented attic provides a simple, yet comprehensive, solution. 

But doesn't a building need to breathe?
Yes, but in a controlled way.  The key to healthy indoor air is control.  By eliminating air leakage and allowing your mechanical ventilation system to do its job, you control the quality of the air that you and your family breathe, and in doing so lower your energy bills and improve your health.  The ZipFoam solution virtually eliminates condensation, duct sweating, infiltration, humidity and therefore, bacteria growth.

How does the ZipFoam solution eliminate bacteria growth?
An unvented design allows you to control humidity levels to within the 45% to 50% range; a level at which molds, mildew, dust mites and many allergens perish.

WARM CLIMATE SOLUTIONS FOR YOUR BUSINESS:
Insulating your business against losses doesn't have to be difficult.  ZipFoam offers a one-stop solution to a variety of problems that commonly plague commercial, industrial and agricultural businesses located in warm climates:  high energy costs, sick building syndrome, moisture problems, inventory losses due to mold & mildew, structure & mechanicals failure (overload) as well as expensive, short lived fixes.  In addition, ZipFoam offers additional value-added benefits.

ELIMINATE HIGH ENERGY COSTS:
According to Florida Solar Energy Center (www.fsec.ucf.edu.com), air leakage has a greater impact than R-value on the performance of a building.  ZipFoam is not just an insulation solution - it's an air sealing solution as well.  In comparison to traditional insulating methods, ZipFoam has all of the benefits and more, with none of the limitations or problems. 

A semi-rigid spray foam solution, ZipFoam is quick and easy to install and offers a permanent solution, even for steel framed buildings.  ZipFoam reduces maintenance costs by reducing moisture problems thereby extending the life of your building and mechanicals.  This improvement in performance can dramatically lower the sizing and operating costs of heating and cooling equipment. 

HOW DOES ZIPFOAM ADDRESS SICK BUILDING SYNDROME?
ZipFoam air seals the building envelope against wind and airborne moisture.  It creates a comfortable, draft- and condensation-free environment in a single application.  By sealing out dust, allergens, odors and other pollutants, ZipFoam allows your air management system to do its job so that the indoor air quality is healthier than outside air.  ZipFoam does not emit gases or odors and offers no support to bacteria, fungus, insects or vermin.  An environment insulated with ZipFoam is a much healthier haven for those suffering from respiratory problems (such as asthma), allergy sufferers and persons with chemical sensitivities. 

CAN ZIPFOAM ELIMINATE MOISTURE PROBLEMS?
Yes.  Because air leakage is the culprit, the only way to eliminate moisture problems is to air seal the building envelope.  By eliminating air movement through walls, floors and ceilings, moisture laden air cannot pass through and affect the indoor environment thus allowing you to control humidity levels to within the 45% to 50% range; a level at which molds, mildew, dust mites and many allergens cannot be sustained.  Moisture and temperature sensitivity related inventory losses will be dramatically reduced. 

DOES ZIPFOAM HAVE LIMITED USES?
No.  The ZipFoam solution can be applied to new or existing (retrofit) construction, and will adhere to virtually any surface.  It allows for architectural freedom and eliminates the insulating and air-sealing woes of metal construction.  With ZipFoam, your new or retrofit building is permanently protected, sealed off from wind, pollutants and airborne sound, and resistant to moisture-related (condensation) problems. 

WHAT ARE SOME OF THE VALUE-ADDED BENEFITS?
Sound and odor control:
  On its own, ZipFoam is not intended to be a sound proofing solution, but it is an effective barrier to airborne sounds and thereby offers sound proofing properties.  Its superior fit reduces airborne sound transfer through roof, floor and walls which means it does double duty and becomes part of a cost-effective sound proofing solution.  Outside noises such as air, road and rail traffic are significantly less noticeable.  Inside, there are far fewer complaints about plumbing and neighbor noise. As well, the elimination of air movement through common walls in multi-dwelling units eliminates cooking odor migration. 

WHAT IS ZIPFOAM?
ZipFoam is an American-made spray foam insulation solution that is environmentally safe.  It allows foam to be sprayed without formaldehyde or ozone destroying gases (HCFCs or HFAs).  The result is a semi-rigid foam that is soft to the touch, non-toxic and permanent because it will never shrink, sag, or settle.  It's the ideal solution for metal buildings due to its non-corrosive and adherence properties. 

HOW QUICKLY AND EASILY CAN ZIPFOAM BE INSTALLED?
ZipFoam is a scheduling solution too!  ZipFoam is sprayed or injected on site by trained installers, independent of other trades.  Installation is not delayed by weather conditions.  ZipFoam expands to fill every crevice, and cures in less than one minute and may be covered immediately thereafter.  Excess material is easily trimmed.   

IS ZIPFOAM EXPENSIVE?
No.  Like any real solution, ZipFoam more than pays for itself.  In addition to insulating, ZipFoam offers many more benefits and value.  Most importantly however, ZipFoam eliminates the headaches associated with most other types of insulating techniques. Best of all, ZipFoam is American made and installed by Indoor Air Quality and Energy Efficiency Experts.
