You say you dont want foam. What is foam? Plastic! What is the poly you propose to install? Plastic! So you can have plastic or plastic, which will it be?
Cellulose is going to tract the humidity level…"
"So Bob are you more worried about the temp in your attic or the energy efficiency of your house. If you have a poorly insulated and air sealed attic what you will do is create a negative pressure in the attic. Some of the make up…"
"It really doesnt take much to vent an attic. The biggest benefit is to remove moisture from building up and to vent excessive heat. I say excessive heat....some people think you need to get the air temp close to the out door temps.…"
"I am a skeptic. I think there was probably a lot of air sealing benefit. As we know air sealing is the place to start. If you didnt do before and after testing how much benefit can you assign the the RCC and how much was air sealing.…"
"Uv lights do not create any byproducts. You may be thinking about ozone. Ozone has some good uses in UNOCCUPIED buildings, Ozone will damage many things so regular use is not a good thing but if you have smoke or other odors you…"
"How do you measure what they prevent? For some people they can make a difference and others they may not see a noticeable diference.
I would not put one in a filter box. I would mount it above the coil. I think in some circumstances…"
"Was there a catalyst? For disinfecting you are looking at UVC not UVA. I have seen systems that UVA activates a catalyst.
UVC is used in hospital operating rooms and have been shown to reduce the infection rate. UVc is effective at…"
"I think it boils down to how well the hatch is insulated and sealed. If the hatch is sealed tight and insulated to the same level as the attic floor then it would work in many climates.
I think the proper way to do it would be to depressurize the…"
"Jerry that is a lot of twisting of facts. Radiant barriers work on one of the 3 methods of heat transfer. It does nothing to stop convection or conduction. So it works during daylight hours when the sun is beating down on a roof.
"That sounds like a ozone generator. I always advise against introducing ozone in to an occupied building. Ozone is a very caustic gas, that is why it can clean surfaces. Putting this system in a small room could elevate ozone to very…"
"$400 is over priced.
What you should know about furnace filters is that they should only do a marginal job of removing air borne particulates. The more you filter the more you restrict the air flow and hurt the efficiency of your…"
"Bob 4 inch filters are not a better filter, they have more surface area and last longer. If you look the the MERV rating of the 4 in filters they are in the range of an 8 or 10. That is mid level filtering.
Furnace filters are a…"
"Selling a house as is means you are not willing to do any repairs that the seller may request. You are still required to tell a prospective buyer and know conditions. Most states have a seller disclosure form that tell you what needs to…"
"That is a horrendous job of installing batts. A perfect example of why I would never use batts.
If you look in the picture you see a thicker bead that sticks up from the framing. Then at the top of the picture it is very thin. I…"
"I spoke with a builder who has tried both the Owens product and the Knauf product.
They quit using Owen. It sprays on and bubbles up a little. He couldnt get a good surface for the drywall to sit on. I cant remember all the particulars but he…"
