Is it time for Insulation Installation Cost in Sunnyvale? What is the best type to choose? Let us focus on four specific types. One is blown attic insulation the other is batt insulation. Each type has pros and cons. However, which is the best choice for you.
One of the best advantages of blown attic insulation over batt is that the blown style covers everything; while there can be open areas in the batt type.
When you’re looking to have your home or building insulated with spray foam insulation, you have a couple of product choices. Whether you go with closed foam or open foam insulation, the differences in their make will make a big difference in which one will work best for your needs.
Radiant barrier insulation has one reflective side that is made from an aluminum coating. Any radiant barrier insulation can be installed in an existing or new home. The reflective side of the barrier insulation is made to face the open air pocket of the surface.
Almost all Insulation Installation Cost in Sunnyvale are tested and rated as fireproof. If for some strange reason you find one that is not, stay away from that product.
How To Install Blown In Attic Insulation
Adding insulation to your attic is a great way to save energy, but there are a number of choices that you need to sort through. What is the best type for your situation? What is the best location for this added insulation? How much should you add?
The first thing that you need to determine is how much insulation you already have. Measure the depth and determine the type. Then multiply the depth by the appropriate value: Cellulose: 3.1, Fiberglass Batt or Blown: 3.7, Closed-Cell Foam: 6.2, Open-Cell Foam: 3.6.
Before you move any further to insulate your attic, you should make sure that you have any knob and tube wiring in your attic that would be covered by insulation replaced. The wires in this type of system need to be in the open air in order to dissipate heat. If they are surrounded by insulation this will trap the heat and cause a fire hazard.
Once you have calculated the R-value of your insulation, you need to determine how much more you should add. Energy Starr has developed recommended levels of attic insulation for every Zone throughout the US. See map at Energy Star and chart below. However, what it boils down to is most houses don't have enough insulation. R-30 is the bare minimum and unless you live in south Florida, the recommended amount is twice that.
Radiant Barriers: work differently than thermal insulation. They reflect the heat away from the thermal insulation, instead of slowing the heat transfer through it. This effectively increases the performance of your thermal insulation in your attic by 50% to 70%. Radiant barriers work best if they are installed between the attic insulation and the roof sheathing, and when they are sloped so that dust will not accumulate on it as quickly. Furthermore, radiant barriers are fairly inexpensive and easy to install.
Your last step is to determine if you are going to add thermal insulation, a radiant barrier, or both. If your house already has what is the code minimum in many locations of R-30, adding a radiant barrier should boost its effectiveness to 45 or even 50. Or if you have an old house with 5 ½" of fiberglass or cellulose (R-17 to R-20) and you add another R-19 and a radiant barrier, you effective insulation value should be between 54 and 65.
Is Radiant Barrier Worth Adding To Your House?
Industries have decided to bring the best quality products and the most affordable insulation to home-owners across the county. Traditional materials made from fiberglass or cellulose can insulate the house but can damage the environment. Many such industries have decided to create quality products with the highest renewable resource content to encourage homeowners to purchase a product that protects the environment.
The Benefits of Spray Foam
Many contractors are using spray-on insulation, made of polyurethane froth, which is the same kind of appliance that manufacturers have used in refrigerators and water heaters. It can be used as an insulating and air sealing product for residential wall and ceiling cavities. The insulation is sprayed onto the wall cavities thereby expanding it. The liquid is sprayed through a nozzle into wall, ceiling, and floor cavities where it expands to fill every nook and cranny. Because it expands into tight areas, and its froth is ideal for insulating steel framing and outlets. This product can seal and fill tiny unseen cracks and seams, eliminating energy-wasting air filtration. Excess froth is scraped off the sides to form a uniform wall cavity. It makes it easy to completely fill wall cavities with insulation and to also perform air sealing. It is applied as a liquid which contains a polymer and a foaming agent.
The foam product also helps control moisture condensation because it does not shrink or settle. It is fire resistant and reduces heating and cooling costs significantly and its thermal seal keeps cold air in and unwanted air out. Spray on insulation has also been known to improve indoor air quality, thereby decreasing the likelihood of allergies. It also has high quality sound control, and significantly reduces dust, mold and mildew accumulation. Most importantly, the froth from the spray has been known to help the economy and the environment by using recycled materials in the froth. The containers are usually also recycled. Those who use this product are committed to providing quality renewable resource based building materials.
The Costs of Spray Foam Insulation
If an individual decides to get spray foam product, they must understand that the initial product costs may be higher than with traditional devices. But this foam product is not a do-it-yourself project and therefore homeowners will have to hire a contractor certified in applying this new technology. Since this is a fairly new product, there may not be many contractors in the area who can apply insulation. This is also a complicated and messy process, so it may be easier and more effective in new construction rather than existing homes. Furthermore, froth insulation in sidewalls may cause difficulties to contractors who are not familiar with its properties. The initial cost of using this foam product is about three times more than traditional materials. Even though it is more expensive, the insulation could lower your utility bill by as much as 30 percent, paying back the cost difference in energy savings in a few years from now.
