Should I install Novitherm Heat Reflectors behind all heating units on interior walls as well as those on exterior walls?

Novitherm Heat Reflectors are normally installed behind heating units on exterior walls to prevent heat loss to the outdoors. However, the radiant heat reflective capabilities of the Novitherm Heat Reflectors, also improves warm air circulation and comfort when installed on interior walls. This could be a benefit especially to colder rooms in your home.
