Spray Foam Insulation
Spray Foam Insulation is a spray-applied foam that can form a continuous insulation and air sealing barrier on walls, roofs, around corners, and on all contoured surfaces. It is made by mixing and reacting unique liquid components at the job site to create foam. The liquids react very quickly when mixed, expanding on contact to create foam that insulates, seals gaps, and can form moisture and vapor barriers. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints.
Air Sealing reduces the amount of air that leaks in and out of your home in a cost-effective way to cut heating and cooling costs, improve durability, increase comfort, and create a healthier indoor environment. While applying spray foam insulation is a big step towards air sealing, there is more to be done: proper weather stripping, caulking and sealing windows and doors during installation, to name a few.
Shell Commissioning manages the shell construction, ensuring all penetrations, be it windows or light fixtures or ventilation, are properly sealed, and all applied foams and sealants are installed and tested ensuring that construction meets or exceeds performance specifications.
Air Source Heat Pumps
An Air Source Heat Pump (ASHP) is a system which transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called “reverse-cycle air conditioners.”
In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating and/or domestic hot water supply. Until recently an ASHP was not a viable option in the northeast, but extraordinary upgrades have occurred and now ASHP are considered very reliable and very efficient options.
Geothermal energy is defined as heat from the earth. It is a clean, renewable resource that provides energy in the U.S. and around the world in a variety of applications and resources. Here in New England, geothermal is often references as Ground Source, the application is a series of wells where closed loop piping circulates water gaining geothermal heat in the process.
Biomass is a renewable source of fuel to produce energy because waste residues will always exist – in terms of scrap wood, mill residuals and forest resources; properly managed forests will always have more trees; and we will always have crops and the residual biological matter from those crops.
Solar energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible.
