How does insulation reduce heat loss? The use of more loft insulation can reduce heat loss by reducing the movement of air upwards. The fibres of the insulation can also prevent the trapped air from circulating and causing convection currents.
How does insulation keep heat in? Insulation doesn’t “heat” an area, it simply slows down heat movement through building materials. Since heat will always move to a colder source, in cold climates, insulation slows the heat from leaving the house and in hot climates insulation slows down the hot outside air from entering the cool inside.
How does foam insulation reduce heat loss? Insulating materials are bad conductors and so this reduces the heat loss by conduction. The material also prevents air circulating inside the cavity, therefore reducing heat loss by convection.
Do insulators increase heat loss? Insulation prevents heat loss by trapping air, which is a poor heat conductor. Lastly, heat transfer by radiation is the transfer of energy from one location to another by electromagnetic radiation.

How to clean foam insulation?
Acetone is a solvent that dissolves uncured polyurethane foam and can be used to clean up foam before it cures. Acetone-based nail polish remover will also work to remove uncured foam. Unfortunately, these products don’t have any effect on cured foam. Once it cures, you’ll have to scrape or sand off unwanted foam.
