When should you not use a vapor barrier?
Experts advise builders against the installation of an interior polyethylene vapor barrier unless they are building in a very cold climate — for example, in the colder regions of Canada and Alaska.
What is the downside of radiant barriers?
Radiant Barrier Moisture Problems
The other main issue that can impact the performance of any radiant barrier is moisture. In colder weather, radiant barriers can sometimes develop condensation. This issue is most prevalent in climates where the temperature regularly falls below zero degrees Fahrenheit.
What is the R-value of the barrier?
In the context of construction, the R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive flow of heat.
Does radiant barrier insulation really work?
Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it's usually more cost-effective to install more thermal insulation than to add a radiant barrier.
