Insulated concrete walls are strong, efficient
Found in the official guide to the 22nd Annual Building, Home & Remodeling Show (March 5, 6, &7, 2010) this article highlights the benefits to be found in building with Insulated Concrete Forms (ICF).
Introduction
Stonecraft Construction is at the forefront of residential construction, incorporating methods that ensure a safer, healthier, more comfortable, and energy efficient home. Imagine, Inc. created Stonecraft Construction so that we may be able to offer the residents of North-East Alabama a new option, when they are searching for or are planning to build their DREAM HOME.
Stonecraft Construction is pioneering ICF (Insulated Concrete Forms) construction and is a distributor of the NUDURA forms. ICF construction has many benefits compared to traditional stick-framing. ICF uses a minimum of 4 inches of poured concrete encased in 2 inches of foam. This technique translates into a solid, air tight home, producing maximum energy efficiency (lower utility bills), healthier living, and ultimately a more comfortable home. Not to mention, a haven from “The Big Bad Wolf”.
Stonecraft Construction is also invested in building with Structural Insulated Panels (SIPs) that require less energy and raw materials to produce when compared to other structural building techniques and have the ability to drastically reduce waste generated during construction by being fabricated to specifications on a per job basis. Check out the website of FischerSIPS for more information on this effective energy savings construction method and its health benefits: A home built with SIPs creates an airtight building envelope that limits incoming air to controlled ventilation, resulting in optimal indoor air quality.
Stonecraft Construction also takes an active role in helping homeowners with remodeling projects. Our limits are only determined by your imagination, so dream about all the possibilities. If it falls under the title of home construction, Stonecraft is who you need to talk too.

Truseal: In Action
Glossary
Air Changes per Hour (ACH) An expression of ventilation rates – the number of times in an hour that a home’s entire air volume is exchanged with outside air.
Air barrier A layer of material resistant to air flow usually in the form of polyolefin (i.e. Typar®, Tyvek®, and other house wraps). A material which is applied in conjunction with a building component (such as a wall, ceiling or sill plate) to prevent the movement of air through that component.
Air barrier system The assembly of components used in building construction to create a plane of air tightness throughout the building envelope and to control air leakage.
Blower Door Diagnostic equipment consisting of a fan, removable panel and gauges, used to measure and locate air leaks.
Blowing agent A gas or a substance capable of producing a gas used in making foamed materials.
BTU British Thermal Unit – The amount of energy that is required to raise 1 lb. of water up 1° F
BTUH A rate of energy transfer – can be expressed as BTUs/hour
Building Envelope The external elements walls, floor, ceiling, roof, windows and doors of a building that encloses conditioned space; the building shell.
Capillary Action, Capillarity The movement of liquid within a material against gravity as a result of surface tension.
CFC (Chloroflourocarbon) Any of various halocarbon compounds consisting of carbon, hydrogen, chlorine, and fluorine, once used widely as aerosol propellants and refrigerants. Chlorofluorocarbons are believed to cause depletion of the atmospheric ozone layer.
Combustion efficiency A measure of useful heat extracted from a fuel source by an operating heating appliance. For example a furnace with a combustion efficiency of 60% converts 60% of the fuel’s energy content into useful heat. The rest is lost as exhaust gases.
Conduction Transmission of energy (heat/sound) through a material or from one material to another by direct contact. Materials with low rates of conductive heat transfer make good insulation.
Convection Transmission of energy (heat/sound) from one place to another by movement of a fluid such as air or water.
Density Determined by the weight expressed in pounds of a cubic foot of spray foam.
Dew Point The temperature at which a vapor begins to condense.
Diffusion The movement of water vapor from regions of high relative humidity (RH) toward regions of lower RH driven by a higher to lower temperature differential.
Exfiltration Uncontrolled leakage of conditioned air from inside the home to the outside.
Flame Retardant A substance, which is added to a polymer formulation to reduce or retard the tendency to burn.
Flame Retarded (Adj.) The property of a material to which flame-retardant has been added.
Flame Spread Standard test for determining relative combustibility. The flame spread of a tested material is rated relative to red oak (flame spread = 100).
Flammability Relative ability of a material to support combustion as expressed by its flash point.
Heat loss Heat that is lost from a building through air leakage, conduction and radiation. To maintain a steady interior temperature, heat losses must be offset by a combination of heat gains and heat contributed by a heating system.
Heat recovery ventilation system A mechanical ventilation system that recovers energy from exhausted indoor air and transfers it to incoming air. This system usually incorporates an air-to-air heat exchanger which transfers the heat from exhaust air to the incoming air or vice versa.
HCFC (Hydrochlorofluorocarbons) are compounds containing carbon, hydrogen, chlorine and fluorine. They have shorter atmospheric lifetimes than CFCs and deliver less reactive chlorine to the stratosphere where the “ozone layer” is found.
Humidistat A humidity sensitive control device that signals the ventilation system to operate if the humidity goes above a preset limit.
Hydrophobic Having no affinity for water; not compatible with water. “Water fearing”
Infiltration Uncontrolled leakage of air into a building through cracks around doors, windows, electrical outlets and at structural joints.

Permeability The time rate of water vapor transmission through unit area of a material of unit thickness induced by unit vapor pressure difference between two specific surfaces, under specified temperature and humidity conditions.
pH A measure of acidity/alkalinity of aqueous mixtures. A measure of pH 7 is neutral, lower is more acidic, higher is more alkaline.
PSI Pounds per square inch.
Radiation Transfer of energy (heat/sound) from one object to another through an intermediate space. Only the object receiving the radiation, not the space is heated. The heat is in the form of low frequency, infrared, invisible, light energy, transferring from a “warm” object to a “cold” object. It is known as the “black body effect”.
Relative Humidity The ratio expressed as a percentage of the amount of moisture air actually contains to the maximum amount it could contain at that temperature.
R A unit of measurement of resistance to heat flow in hr. ft2 ° F/BTU.in.
RSI A unit of measurement of resistance to heat flow in m2 ° C/W per 25 mm. R = 0.176 RSI
