Drastically Reduce Your Energy Consumption While Strengthening Your Home’s Structure and Reduce Outdoor Noise
Home Performance Group’s holistic approach emphasizes energy conservation through tight building construction. HPG integrates mechanical, electrical, and plumbing systems with the building envelope to create extraordinary home comfort while maximizing overall building performance. Use of Spray Polyurethane Foam (SPF), “spray foam” is an integral component with our total home approach.
Changes to the residential building codes and consumer demand for energy efficient homes that perform consistently year-round without comprising design vision, comfort and performance make SPF an excellent choice.
HPG’s proven experience in the selection and installation of spray foam and blow in insulation is coupled with other advanced building sciences: ground-source heat pumps (GSHP), radiant heated floors, walls, and ceilings, advanced controls, renewable on-site power generation with solar photovoltaic (PV), emergency whole home back-up generators, and insulated concrete form (ICF) construction.
- Spray foam insulation minimizes both conductive and convective heat loss in the winter and heat gain in the summer
- SPF improves indoor air quality by sealing gaps, cracks and holes that cause air leakage into the home
- Single touch-point in design/build projects with an integrated team ensures project consistency
- Advanced building science ensures the comfort and durability of energy-efficient building
- Powerful system when used in conjunction with ultra-efficient geothermal heating and cooling system and PV solar arrays.
Spray Foam is an Energy Efficient Solution
As much as 40% of a buildings energy is lost due to air infiltration. Gaps, holes and air leaks can make energy bills unnecessarily high. Spray foam performs as both an insulation and air barrier, closing gaps that let air escape and that add dollars to monthly energy bills.
As much as 60% of the energy used in a home goes to heating and cooling. Maintaining an optimal heating, ventilating, and air conditioning (HVAC) system can make your home more energy efficient. With spray foam, HVAC sizing can be reduced as much as 35%. Air leaks that can waste energy and drive up utility bills can be filled with spray foam.
Some common spots for air leaks that can be sealed with spray foam include the area behind knee walls, attic hatches, wiring holes, plumbing vents, open soffits, recessed lights, furnace flue or duct chase ways, basement rim joists, windows and doors.
“Cool roofs” are designed to maintain a lower temperature than traditional roofs. They are light in color and reflect sunlight. Closed cell spray foam is applied to the underside of a roof resulting in cool roof performance.
Closed Cell Spray Foam Can Improve Building Strength and Durability
Applying a closed cell spray foam to a roofing system can improve the buildings strength. In fact, SPF roofs have effective life spans that can exceed 30 years. Spray foam can help create a strong bond to protect the roof and can eliminate water seepage through weak spots. It can also be applied in a sloped manner to allow water to easily drain off the roof
The bond that SPF forms can increase a buildings resistance to wind uplift. During periods of high wind, a building with spray foam roof generally experience less damage. One prominent spray foam technical consultant notes, “when added to the inside of a structure, spray foam “glues” the whole building together, enhancing overall wind and pressurization resistance.”
SPF insulation adds strength and resilience. The Federal Emergency Management Agency (FEMA) has classified spray foam insulation as highly resistant to floodwater damage, saying, “these materials can survive wetting and drying and may be successfully cleaned after a flood to render them free of most harmful pollutants.”
Spray foam prevents moisture and condensation throughout the building, helping prevent mold and mildew. Applying closed-cell spray foam in the cavities of walls increases the durability of a wall system because of its ability to conform and adhere to the surface upon which it is sprayed. A wall with spray foam insulation is better able to maintain its shape under duress than a wall assembly without spray foam.
Spray Foam and Indoor Air Quality
Spray foam insulation can make your home or building more comfortable in many ways. SPF helps minimize airborne sound transmission. Sealing a building’s air leaks prevents drafts, creating more comfortable indoor environment and providing better indoor temperature control. Closed-cell spray foam acts as a barrier to water and vapor, helping to prevent condensation and water intrusion. Sealing gaps with spray foam can provide a barrier against pollen, dust, and insects, which can be especially helpful in households with allergy sufferers.
Spray Foam Learning
Spray Polyurethane Foam(SPF) is a spray-applied plastic that can form a continuous air sealing barrier on walls, roofs, ceilings, around corners and other surfaces. SPF insulation is known to resist heat transfer extremely well and offers a highly effective solution in reducing unwanted air infiltration.
HPG employs low Volatile Organic Compounds (VOC) and low Global Warming Potential (GWP) spray foam products.
Like most other build-on-site construction products, SPF insulation varies by installer. The most often cited problems of spray foam insulation can be prevented with careful installation and rigorous quality assurance inspection immediately following installation. HPG conducts a visual walk-through inspection with the client as well as an IR inspection of the project ensuring the four most common installer mistakes do not become your problem.
- Spray foam isn’t thick enough. This mistake is most common with closed cell insulation, but does happen with open cell as well. Open cell insulation usually fills the framing cavity making depth and fill inspection much easier. Close cell insulation has a higher R-value and therefore generally is not used to fill between framing inspection should be more careful. A final note, average thickness should not be used as the inspection criteria. Even small points of thin or no insulation can have dramatic effects on system performance.
- Spray foam is missing causing air leakage. HPG implements a visual walk though and Infrared (IR) inspection of the installation prior to closing the project. This ensures all locations along the building envelope have been sprayed ensuring the lowest air leakage possible.
- Spray foam is not in the right places based on the building envelope. HPG conducts a thorough plan review and site walk through prior to beginning the insulation application. These reviews and site visits ensure our installer clearly understands the building envelope, the type of foam needed, and the thickness required.
- Spray foam contracts and pulls away from framing. HPG ensures that one installer manages the foam rig to ensure quality chemical batching, proper mixing and temperature control. These safeguards help to mitigate applied spray foam from contracting or pulling away after installation.
