Is it time for Insulation Cost in Roanoke? 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 Cost in Roanoke are tested and rated as fireproof. If for some strange reason you find one that is not, stay away from that product.
Special Applications for Spray Foam Insulation
The energy conservation industry has experienced explosive growth while continuing to develop new technologies. For the consumer, deciding which materials and devices offer the greatest return on investment can often be confusing.
Over the last five decades, thorough research reveals that the greatest energy savings per dollar invested comes from maximizing the insulation value of a home or business. Among the different insulation materials, spray foam insulation offers substantial advantages over competing systems.
Heat Transfer: Conduction, Convection, and Radiant
The purpose of any insulating material is to slow the transfer of heat. To compare the relative effectiveness of the different insulation alternatives, it is important to understand how heat moves through materials and space.
R-Values and Spray Foam Insulation
Most insulation systems are designed to address conduction fairly well, while doing a poor job of addressing convection and radiant heat transfer. The insulation industry has adopted a standard called "R-value" which is a measurement of conductive heat transfer through an insulating material over a given period of time. The problem with this standard is where its focus is, conductive heat transfer which is only small part of the pie when it comes to whole issue of heat transfer. Spray foam insulation is the only type of major insulation that performs at a high level across all three fronts of heat transfer: conduction, convection, and radiant heat transfer which makes it the best choice for keeping your home comfortable and your energy costs low.
Heat Transfer, R-Value, and Spray Foam Insulation
House attic mold is one of the most "popular" items in my property inspection reports. And now is time for an explanation of how to kill mold and / or how to clean mold in the attic. But before I do that, let me give you a little advice, something to consider before you sign a few (if you're lucky) thousand dollars contract agreement with a mold remediation company.
Attic mold remediation TIP - an alternative (to consider):
Let us assume that you are in the middle of a real-estate transaction, and the home inspector just revealed to you, that your entire house attic is contaminated with mold.
If you have a brand new roof, you can only blame yourself or try to blame the roofing contractor for not checking the attic before replacing the roof (he will laugh at you unless you've actually asked the guy to check the attic before the roof replacement). If you have an older roof, the importance of this advice is even greater.
Call at least 2-3 mold remediation companies for an estimate - specify to the representatives, that you not only want to have the mold removed, but also attic ventilation system corrected / installed if necessary / ask if the attic insulation requires replacement.
With the numbers from the mold remediation contractors, call 2-3 roofing contractors, and ask them for a quote on the roof replacement cost including decking boards / plywood (ask the roofer to check the attic area), attic ventilation improvement, and insulation if necessary.
Be cautious if they only suggest humidistat controlled power vent installation - without properly functioning soffit vents or any type of vents along the lower portion of the roof this might not be an adequate solution.
If the attic insulation replacement is not required (it most cases it will not be possible to tell without laboratory testing), make sure it's sealed with plastic foil before the roof and its decking replacement. Fold the foil sealing its contents after the contaminated decking has been removed, and dispose of as a regular waste (EPA recommendation).
I personally wouldn't even attempt to do it myself, so my suggestion is:
Use a professional mold remediation company:
- check their background and check it manually by calling their clients
- ask for clients who had their attic mold remediated approximately 1 year ago - it usually takes a winter for the mold to start growing again if the job wasn't fully completed
- Insist on removing the mold completely instead of encapsulating it (Media Blasting methods give the best results).
- Encapsulation is simply a process of covering the mold contaminated surface with paint (paint like product) that contains (or at least some of them do) mold killing chemicals
If your attic mold is properly removed and all of the issues responsible for its growth corrected, which is even more important than mold removing, it will not re-grow / no need for encapsulating.
- Hire a different contractor for mold testing and mold remediation to eliminate conflict of interest.
- Make sure that you perform an independent clearance test after the mold remediation process completion.
- Clearance test is to determine if there are any mold spores remaining in the previously contaminated area
All wood (framing and decking) surfaces should be perfectly clean (like brand new), unless there was some rotting that resulted from leaking roof or extremely humid conditions in the attic - those sections of wood should be either replaced or reinforced from underneath. You don't want anyone to fall through the roof while servicing it or just inspecting.
