Overall, when installed properly radiant barriers can provide reduced energy costs and cooler attics.

There are also some comfort improvements. The radiant barrier creates a cooler attic which helps reduce cooling costs. The reason this method is so effective is because radiant barrier makes regular insulation more effective.

Laying Foil Over (On Top of) Insulation on the Attic Floor This is probably the easiest method to install Radiant Barrier AtticFoil™ is to lay the foil out OVER the existing insulation on the attic floor. Thereof, can you put radiant barrier over insulation?

Seal all seams with aluminum foil tape.

Boasting an undoubtedly excellent 97 reflectivity rating, the Houseables Radiant Barrier is a true radiant-heat-shielding workhorse.

Unroll and staple reflective insulation to the under side of the rafters. This radiant barrier can be installed in an attic, around a greenhouse, under the floor of an RV, and even around existing insulation.

Install unfaced mass insulation between rafters ensuring a minimum of 1" ventilation space between the mass insulation and the underside of the roof decking.

In cool climates, however, it's usually more cost-effective to install more thermal insulation than to add a radiant barrier. The reduced heat gain may even allow for a smaller air conditioning system. Some studies show that radiant barriers can reduce cooling costs 5 to 10 when used in a warm, sunny climate. Radiant barriers are less widely known or used than insulation. Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. If you have a radiant barrier with a really low level of emissivity, then you have a very effective radiant barrier.
