because otherwise it ll be cold and ur house could go cold, damp, and horrible
There is a layer of vacuum which surrounds the flask, then the inside is covered by shiny material which will reflect the heat back into the flask, there are two lids, and there is an indirect gap of about 0.01mm.
Heat loss from a home occurs through conduction (through walls, windows, and roof), convection (air drafts), and radiation (heat emitted from objects). Proper insulation, sealing of gaps and cracks, and using energy-efficient windows and doors can help reduce heat loss. Heating systems should also be well-maintained to operate efficiently and minimize heat loss.
If there is one thing you should know, it's infrared waves. Obvi.
Conduction and convection are prevented by a vacuum because there are no particles to transfer heat through direct contact or movement. Radiation is the only method of heat transfer that can occur in a vacuum, as it does not require a medium to propagate the heat.
Possible mechanisms of heat loss contributing to Joel's feelings of coldness could include conduction (loss of heat to a cooler surface by direct contact), convection (movement of air carrying away body heat), radiation (heat loss to cooler surrounding objects), and evaporation (loss of heat through sweating). Inadequate clothing and low ambient temperature can also exacerbate heat loss.
cover up the cracks in your house

yes by for example double glazed windows, closing off chimleys, stopping drafts and fibre glass in your attic.
Yall should know this
heat loss
Hemostasis
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.
Heat can prevent water, by evaporation.

the thicker the insulation is then there will be less heat loss. The material also affects heat loss
