What kind?
Friable Asbestos? Yes.
Non-friable Asbestos? Not so much, but still not great.
Vermiculite? It may or may not contain asbestos.
Fiberglass? Mice love it, and it can make dust, and it only really insulates if it's completely encapsulated by wall, stopping air movement.
Foam? It's combustible, and current thinking is that it should be covered by a 15 minute smoke barrier. (If there's a fire, you have 15 minutes to get out before it produces toxic smoke.) There are expensive paints that can do this, or you can cover it with sheetrock.
The best insulation to use is spray foam, although it is an expensive option. Another option that is less expensive is 1" rigid foam board. Both of these options eliminate the need for tar paper or a vapour barrier as they are self-sealing applications. Avoid using batt insulation w/vapor barrier in basement applications as condensation may occur which will encourage mould growth.
You could friction fit some 3/4" Dow styrofoam on the inside frame during wintertime.
there are many ways to prevent heat loss in your house including; loft insulation, double or triple glazed windows, installing pipe covers on exposed water pipes, purchasing a boiler jacket and even special wall insulation. i hope this advice helps you.
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.

That depends on what type of insulation you're talking about. Exposed foam insulation generally isn't dangerous. Exposed asbestos insulation might be.
The best insulation for a basement ceiling is typically rigid foam insulation or spray foam insulation. These types of insulation provide good thermal resistance and help prevent moisture issues in the basement.
The best insulation for a basement is typically rigid foam insulation, as it provides good thermal resistance and moisture resistance.
Spray foam insulation on basement walls provides better insulation, reduces energy costs, prevents moisture and mold growth, and improves overall comfort in the basement.
The best insulation for concrete basement walls is rigid foam insulation. It provides high R-value, moisture resistance, and is easy to install.
There are several main advantages of basement insulation. These include: insulating the basement can keep the entire home warmer making significantly lower, it keeps the basement much dryer, and it provides a comfortable living space.
Using an insulation blanket for basement walls can help regulate temperature, reduce energy costs, prevent moisture buildup, and improve overall comfort in the basement.
Probably Insulation...
Rigid foam insulation is commonly recommended for basement walls due to its moisture resistance and high insulating properties.
If the basement is "finished" then yes. If it's a typical basement with exposed joists, no.
Foam insulation for basement walls provides benefits such as improved energy efficiency, moisture resistance, and sound insulation. It helps to regulate indoor temperatures, prevent mold growth, and reduce noise transmission, making the basement more comfortable and energy-efficient.
Vermiculite insulation containing asbestos is about as dangerous as any other type of insulation that contains asbestos. If it becomes airborne and people breath in the fibers, their risk of contracting an asbestos related disease increases. The amount of increased risk depends on how much asbestos is in the insulation, how much becomes airborne, how long the people are exposed to the airborne fibers, and whether they smoke tobacco products.
