When should you not use a vapor barrier?
You may find that vapour barriers are often not required in warmer climates. And, if installed in the wrong climate or on the wrong side of building materials, a vapour barrier can cause more harm than good. This circumstance may prevent water vapour from drying, which in turn can cause rot and mold. (Source: Dupont.)
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?
The R-value per unit of a barrier's exposed surface area measures the absolute thermal resistance of the barrier. , quantifies the temperature difference per unit of heat flow rate needed to sustain one unit of heat flow rate.
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.
