What else can I help you with?
Do you need a vapor barrier on isulation for inside walls?
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.
Is cavity wall insulation a conductor or insulator?
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.
I have a hole in the wall where the stovepipe goes through. Is it safe to put insulation around the pipe to fill in the hole?
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.
How cavity wall insulation helps to reduce heat loss?
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.
Why do air filled cavity wallskeeps a house warmer in winter?
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."
Are R13 walls insulation good?
Yes, R13 wall insulation is considered good for standard wall applications, particularly in moderate climates. It provides a decent level of thermal resistance, helping to maintain comfortable indoor temperatures and improve energy efficiency. However, in extremely cold or hot climates, higher R-values may be recommended for optimal performance. Always consider local building codes and climate conditions when selecting insulation.
How can I effectively insulate a cold wall from the inside?
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.
What is the purpose of wall 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.
how difficult is wall insulation if your new?
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
When constructing a new wall to optimize insulation value is it acceptable to install 2 inch foam board on the inside of the wall in addition to the fiberglass batts between studs?
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.
What are the best materials and techniques for constructing a basement curtain wall to ensure structural integrity and proper insulation?
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.
What is cold wall?
A cold wall refers to a surface or structure that remains at a lower temperature compared to its surroundings, often due to poor insulation or exposure to cold external conditions. This term is commonly used in building science and energy efficiency discussions, where cold walls can lead to increased heat loss and discomfort in indoor environments. In some contexts, cold walls are also associated with condensation issues, as the lower temperatures can cause moisture in the air to condense on the wall surfaces. Proper insulation and design strategies are essential to mitigate the effects of cold walls.
Do you need a vapor barrier on isulation for inside walls?
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.
What is the best way to install insulation in an existing exterior wall?
Without the interior studs exposed or the siding off the outside the best way, really only way is to have the insulation blown in.
How good is spray foam insulation to use on walls?
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.
Are vermiculite insulation granuals waterproof for external wall cavities?
is vermiculite suitable for cavity wall insulation
How do I replace my 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.
