Is your San Antonio heating and cooling bill higher than it should be? Then you might be in need of new insulation in your attic. Your attic’s original insulation will work well for a while, but to be truly effective and keep your heating and cooling costs in control, it will eventually have to be added to or be replaced.
InHomeVest is here to help! We work only with quality vendors who can provide you with the best and most energy efficient radiant barriers like Green Energy Radiant Barrier, ™ a high-tech radiant barrier installed in place of traditional, less efficient, and less environmentally sustainable insulation. Products like these keep you cooler in the summer and warmer in the winter. Most importantly, though, putting in new insulation can save you money by keeping those CPS utility bills down!
Don’t spend your hard-earned money on something that won’t save you money or be effective. Call us today and let us show you what a Green Energy Radiant Barrier ™ can do in place of traditional insulation in San Antonio, Texas. Remember, if you roll it in or blow it in it’s not a Green Energy Radiant Barrier. ™
InHomeVest is your one-stop shop for cooler homes in the summer and warmer homes in the winter. So, stop cooling your attic! Contact us now and we’ll have someone come and check your insulation levels in your attic and get you an estimate – all for FREE and with NO OBLIGATION!

How Radiant Barriers Work
Heat travels from a warm area to a cool area by a combination of conduction, convection, and radiation. Heat flows by conduction from a hotter location within a material or assembly to a colder location, like the way a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Heat transfer by convection occurs when a liquid or gas — air, for example — is heated, becomes less dense, and rises. As the liquid or gas cools, it becomes denser and falls. Radiant heat travels in a straight line away from any surface and heats anything solid that absorbs its energy.
Most common insulation materials work by slowing conductive heat flow and—to a lesser extent—convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must face an air space. Dust accumulation on the reflective surface will reduce its reflective capability. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface.
When the sun heats a roof, it’s primarily the sun’s radiant energy that makes the roof hot. Much of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
A radiant barrier works best when it is perpendicular to the radiant energy striking it. Also, the greater the temperature differences between the sides of the radiant barrier material, the greater the benefits a radiant barrier can offer.
Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. 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.
Types of Radiant Barriers
Radiant barriers consist of a highly reflective material, usually aluminum foil, which is applied to one or both sides of a number of substrate materials such as kraft paper, plastic films, cardboard, oriented strand board, and air infiltration barrier material. Some products are fiber-reinforced to increase durability and ease of handling.
Radiant barriers can be combined with many types of insulation materials in reflective insulation systems. In these combinations, radiant barriers can act as the thermal insulation’s facing material.
