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.
R-Value Comparisons Between Different Types of Insulations
Spray Foam Insulation is a two-component system typically consisting of petroleum oils, plastics, and resins. The polyurethane foam comes in two different forms, open cell and closed cell foam. The polyurethane spray foam is an extremely versatile material that is available in a variety of final physical properties and densities. Although the two types of foam are very similar in their chemical structures their characteristics and capabilities differ in many ways, which makes it necessary for the user to understand the differences of the two materials so he or she can determine which is the right foam for their particular application.
The open cell spray foam insulation contains a density of 0.5lb. per cubic foot. The greater the density of the foam the heavier, or stronger it will become. This particular type of polyurethane foam is referred to as "Open Cell" because of the nature of the chemical reaction during the installation process. When the polyurethane foam is being applied the tiny cells of the foam are broken causing air to fill the "open" space inside the material, resulting in a soft or spongy material. The open cell foam carries an R-Value of 5 to 5.5 per inch (R-Value is the measure of thermal resistance, which can be found by identifying the ratio of the temperature difference across an insulator and the heat flux). 0.5lb. foam products use significantly less material than 2lb. foam products do when completing the same sized job, making them attractive to an individual concerned with conserving the foam material. Due to the fact that open cell foam requires less material, the cost of the project is much cheaper than it would be if you were to apply closed cell foam. Although, Open cell foam is an efficient and economical product it contains some disadvantages in regards to closed cell foam. One of the open cells disadvantages is it has a lower R-Valuer per square inch than closed cell foam does and open cell foam is vapor permeable requiring it to be covered with a vapor retardant material. Although, open cell foam has some advantages and disadvantages it has been recognized as an excellent insulator, air sealant and sound barrier.
There are many things a home or building owner should take into consideration when considering the type of foam that should be used for their particular application. Although both types of foam are by far the best insulators on the market, each type of polyurethane foam possess its own characteristics and capabilities. It is imperative for the user to identify which foam is right for them before applying the product.
The Purpose of Radiant Barrier InsulationRadiant 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. You can place the sheets directly over the top of existing attic insulation on the trusses, they should be over lapped to prevent any gaps where air and heat may be able to escape. You shouldn’t have the barrier insulation coming in contact with the attic insulation or it will transfer the heat right back, resulting in the heat going back into your home. There should be a dead air space in between the radiant barrier insulation for it to do its job properly. Radiant barrier insulation can also be attached right on your walls. For new homes this process is much easier of course, but it can be installed in an existing home as well. For an existing home, you’ll have to take off the drywall or board, so that the barrier insulation can be attached with the reflective side facing the dead air space. A lot more work, but also a lot more reward in terms of the energy savings you’ll see. The radiant barrier allows for the heat to be transferred up through wall to the attic, where it is dispersed through the venting. If you have an attic that does not have the proper venting installed, then chances are the radiant barrier insulation will not be able to work the way it was meant to. This can be rectified by installing some attic vents, or one or two attic fans. By having the proper venting in you attic, it will allow your attic to breath and help keep the water vapor from building up. If the water vapor becomes trapped in you attic, then this will cause major damage over time. Radiant barrier insulation can have a dramatic effect on your homes energy efficiency. A radiant barrier with an ‘R’ value of just 19 has been proven to equal that of regular insulation with a 30 ‘R’ value rating. A popular product is the UltraTouch Natural Cotton Radiant Barrier which is a lightweight, foil faced fire retardant blanket type insulation with multiple uses.
