We are officially in the season of heating, but before long it will be warm again in our area of the country, and staving off the heat is more of a challenge for us than staving off the cold. Proper insulation is important for both heating and cooling, as well as overall energy efficiency, including the installation of a radiant barrier. Radiant barriers in Baytown, TX, can, and should, be part of your attic insulation, but they can often be overlooked. This is unfortunate, because according to Energy.gov, the installation of a radiant barrier can save anywhere from 5-10% in heating costs every year. What is a radiant barrier? We’ll explain more below.
What Is a Radiant Barrier?
A radiant barrier is a hard insulation barrier placed specifically in your attic space with the job of reflecting out the radiant heat that your roof is prone to from direct sunlight. Attic spaces can reach temperatures in excess of 150 degrees during the summer, and a radiant barrier working in combination with good insulation can significantly reduce this heat level. The materials used for radiant barriers are typically OSB boards or plywood (materials can also be batt insulation with reflective foil on one side) with a highly reflective side; the boards are installed perpendicular to the incoming radiant energy. To be fully effective, radiant barriers need at least ¾” of air space between it and the roofing so that the foil can reflect back the radiant heat instead of absorbing it into the board’s material.
