If you want the most efficient home possible, you should use foam insulation instead of the more traditional choice of fiberglass insulation.
Fiberglass has a lower up front cost, but foam insulation can save you money on energy bills month after month, making it a smart choice for Northern Virginia homeowners. Whether you are building a new home or doing a major remodel on an existing home, it can be an excellent opportunity to get the very best insulation choice.
The main benefit of foam insulation is the most obvious one: it saves money. In summers it reduces the amount of heat that enters the home and keeps more of the cooled air from your air conditioning in the home.
In the winter, less of your heated air escapes, keeping your home more comfortable and toasty warm.
One of the keys to foam insulation and what makes it such a superb insulator is that it expands into every nook and cranny, sealing off spots where typical insulation would let heat or cold escape.
Obviously, this leads to lower energy bills. By lowering your energy use, you are also being a friend to the environment.
Foam insulation is also a way to help prevent ice damming. Ice damming happens when snow melts on the roof and then the water re-freezes. This can be a dangerous situation and cause damage to your roof and gutters. When an attic space is properly insulated, the heat is kept in instead of melting the snow on your roof.
When Spray Foam Insulation is sprayed into the stud wall cavity of a home, its two liquid components become chemically bonded, creating a rigid plastic-like material that ties the studs and the exterior sheathing together.
In other words, the use of foam insulation actually strengthens the framing of your house.
Foam insulation has been proven to decrease exterior noise by up to 20 decibels compared to typical insulation options. This translates into a home that is potentially 75% quieter!
Foam insulation does not just keep hot or cold air in your home, it also reduces the amount of pollutants and pollen that can enter. Your home is much more airtight than with typical insulation, and that means less unhealthy particles getting in. It also serves as a moisture barrier that can help prevent mold. Finally, it also helps keeps rodents out – they have no room to move in around the foam insulation!
This may be one of the most important pages on the website if your interest is in spray foam insulation. When it comes time to actually put the foam product in your home or commercial building structure, you must identify whether you will use 0.5 lb./cu. ft., open cell foam, or 2.0 lb./cu. ft. closed cell foam. This makes a big difference in cost, application methods, and performance. With the open-cell vs. closed-cell issue, there are two major factors to understand and consider.
The major application for SPF is in the construction industry as a commercial roofing system and perimeter wall insulation material. Use of SPF for wall insulation in the residential housing sector is a rapidly growing market, due to the many energy saving and air/moisture barrier advantages over traditional fiberglass and cellulose insulation systems. Rigid polyurethane foams are also used as insulation in buildings, on roofs, water heaters, refrigerated transport, and commercial and...
Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes. Insulation: saves money and our nation’s limited energy resources makes your house more comfortable by helping to maintain a uniform temperature throughout the house, and makes walls, ceilings, and floors...
Inadequate Attic Insulation Causes Ice Dams. Ice dams occur when snow melts on sloped roofs and then refreezes again. They are most often caused by attics and roofs with inadequate insulation. Two circumstances combine to make an ice dam. If your home does not have proper and effective attic insulation, heat can escape from the living space during the cold winter months.
Spray Polyurethane Foam Insulation can be used in two common ways to insulate your attic space and protect your home from other weather and moisture related damages. Spray Foam Insulation in the Attic Floor (Vented Attic Spaces) The method of use for spray foam in the attic is often dictated by the building science and design principles your architect and/or builder subscribes to.
How many times have you seen round/oval vents penetrating from the crawl space into the house through rectangular holes? This situation is cause for great concern. We already know that fiberglass batts cannot control or prevent air/moisture movement and infiltration. That being the case, even if your crawl space is “properly” insulated with batts, they will not prevent cold air, warm air, contaminated from...
The walls in your home are the main structural component of the building. In wood frame construction, the weight of the roof, shingles, standing rain water and any snow add weight and exert downward forces on the walls resulting in a compressive force. Strong winds and gusts from storms also impose lateral forces onto your home’s walls. These forces can distort the walls with what is called a “shearing force.” Building codes require that your home’s walls...
One of the fairy tales of our time is the “R-value.” The “R-value” is touted to the American consumer to the point where it has taken a “chiseled in stone” status. The saddest part of the fairy tale is the R-value by itself is almost a worthless number. It is impossible to define an insulation with a single number. It is imperative we know more than a single “R” number. So why do we allow the R-value fairy tale to be perpetuated? I don’t know. I don’t know if anybody knows. It...
1) Energy-Efficient The secret to a energy-efficiency is simple…keep the outside air out, and the inside air in. Unfortunately, air can travel through even the smallest cracks, holes, or seams. Even with traditional fiberglass insulation, air easily passes through the spaces between the wall studs and the insulation batts, reducing the effective R-Value of the assembly.
