The best wall insulation for cold climates is typically foam insulation, such as rigid foam or spray foam. These types of insulation provide high levels of thermal resistance, helping to keep the cold out and the warmth in during winter months.
A vapor barrier is typically not needed for insulation inside walls in moderate climates. However, in colder climates, a vapor barrier can help prevent moisture buildup within the wall cavity. It is best to consult local building codes and climate conditions to determine if a vapor barrier is necessary.
Cavity wall insulation is an insulator. It is designed to fill the gap between the walls, providing thermal resistance to reduce heat loss in buildings.
No, it is not safe to put insulation around the stovepipe. Insulation is flammable and can pose a fire hazard if placed too close to a heat source like a stovepipe. It's best to use proper materials like a high-temperature sealant or a fireproof collar to seal the hole around the stovepipe.
A major part of the heat transfer through a cavity wall lacking insulation is convection - and to a lesser degree radiation. When insulation is placed in the cavity between the walls it significantly reduces both convection (air doesn't move well through insulation like it does in empty space) and radition (the walls can't "see" each other through the insulation). For the insulation to be effective, the thermal conductivity of the material must be low enough that conduction through the insulation is much less than was present with convection.
You just answered your own question. The definition of "insulation" is "something that is a bad conductor" and the definition of a "cavity in a wall" is "an air pocket in a wall."
To effectively insulate a cold wall from the inside, you can use materials like foam board insulation, fiberglass batts, or blown-in insulation. These materials can be installed between the wall studs to help trap heat and prevent cold air from seeping in. Additionally, sealing any gaps or cracks in the wall can further improve insulation.
Wall insulation will save you money in the end. It helps keep the cold/hot air in and the cold/hot air out. It will over time help you reduce your electric cost. It will definitely pay for itself over and over again.
Putting wall insulation in your home is a very big job and not as easy as it seems the best thing to do is to contact a home repair place and have it done by a professional
2" of foam is not very vapor permeable, so from that point of view it makes sense to have it on the inside of walls in cold climates, and people did used to do this in the eighties, but all the current literature says that foam must be used on the outside, with a more permeable vapor barrier on the inside. See BUILDERS GUIDE TO COLD CLIMATES by Joseph Lstiburek.
The best materials for constructing a basement curtain wall for structural integrity and insulation are typically concrete or reinforced concrete. Techniques such as proper waterproofing, insulation installation, and using high-quality sealants can help ensure the wall's durability and energy efficiency.
Without the interior studs exposed or the siding off the outside the best way, really only way is to have the insulation blown in.
A vapor barrier is typically not needed for insulation inside walls in moderate climates. However, in colder climates, a vapor barrier can help prevent moisture buildup within the wall cavity.

The best kind of insulation for a wall will depend on if it is an outside or inside wall and what room it will be for. The roll or blanket insulation made of fiberglass will be good enough for most do it yourself jobs.
is vermiculite suitable for cavity wall insulation
When you replace wall insulation, you are first going to have to tear down the entire walls. You will have to place a layer of foam and fiber to keep the wall warm.
