What else can I help you with?
Does dead air space provide insulation?
As you should know, the purpose of insulation is to create dead air space. DEAD air does not transfer temperatures.
Why is there air space in a thermos bottle?
better insulation
What is air good for?
for thermal insulation
What type of heat transfer does adding insulation slow down?
Generally speaking, insulation slows the movement of thermal energy by convection. The dead air spaces in fiberglass insulation make it a good bet to put in walls and under roof spaces. Styrofoam coolers work because the many, many tiny air spaces in the styrofoam are places where air is trapped, and those are dead air spaces.
Why is old putty good for insulation?
I am not sure where you heard this but the thickness of old putty against the thickness of insulation for r-value is not as good. The best insulator is air. Fiberglass insulation has a high r-value because of the air it holds not the fiberglass itself. So that's why you don't cram 6in fiberglass into a 4in space, it does not work when you compress it.
Can plexiglas be used on the inside to insulate single paned windows?
Yes, even plastic bag can be used. You just need to create a space of dead air to cause insulation.
How can vacuum flask keep hot things hot and cold things cold?
The statement of calling it a vacuum mean there a no atoms between a space without the atoms or molecules in this space heat can not be transferred. Without this transfer of heat things can not heat up or cool down.
How does heat escape an empty warm house with loft and cavity wall insulation and new double glazing using energy transfer and how does the insulation reduce the rate of the heat loss?
Heat will always migrate through anything. The rate is the only thing we can control. Dead air space (motionless air) is the best natural insulator. Fiberglass insulation is used to try to trap as much air and hold it as motionless as possible. This is why you should never compress insulation; you're pushing out the trapped air.
Is straw is a good insulator?
Straw can be a good insulator due to its ability to trap air within its hollow stems, creating pockets of dead air space that reduce heat transfer. However, its insulation properties can vary depending on how tightly packed it is and what it is being used to insulate against.
Are air pockets good insulation?
Air pockets can act as good insulation because they limit heat transfer by reducing the convection of air. Materials like foam, fiberglass, or double-pane windows utilize this principle to improve insulation in buildings and homes.
How does polyurethane foam keep a house warm?
like any good insulation it has gazillions of microscopic dead air spaces that effectively block heat and cold transfer.
Insulation is a material that has lots of pockets of trapped air. Air is a good insulator without loft insulation the roof space is full of air so why does that not keep temperature stable?
The insulation is a better insulator than air is. Pockets are there to allow 'slow' airflow so the house breathes and keep the insulation from molding.Also the air only acts as an insulator if it is trapped. If free it moves around and loses it insulating ability. Air in your attic (loft) Does act like insulation, but a very poor one.The same principle is in your double pane storm windows. if one of the panes crack, or breaks, the insulating value of the window falls.
