The orientation of your foil insulation depends on the climate your place is constantly experiencing. Take note that if it is hot outside and you want to stop the heat from coming to your home, the reflective part of your foil insulation must face outside.

Benefits Of Using Foil Insulation

Foil insulation is a desirable form of insulation due to its various advantages. Having it installed on your walls can significantly enhance the thermal performance of your home.

It can also shield your interior from dust and wind, and some people also use it to lower their energy costs.

Does Foil Insulation Need An Air Gap?

One of the considerations you should remember when installing foil insulation on your walls is the air gap. Your foil insulation will not work effectively if not for the air gap.

Your foil insulations require an air gap of approximately one inch when you install it on your walls. It is not a problem if you opt to have bigger air gaps because they are actually effective. More significant air gaps can encourage more airflow, keeping the temperatures down.

Take note that the air gap in your foil, regardless of which side it is, will not affect how the foil insulation works when it comes to keeping away or retaining the heat.
