Why is my upstairs so hot even with the AC running?

If you live in Texas, you know the feeling: your AC is set to 70 degrees, your downstairs feels great, but the moment you walk upstairs, you hit a wall of heat. Most homeowners think they need a new AC unit, but the problem is actually sitting right above your head.

The "Sponge" vs. The "Shield" Standard fiberglass insulation is like a thick blanket. It’s great for keeping heat in during a winter freeze, but in a 105-degree Austin summer, that fiberglass acts like a sponge. It absorbs the sun’s radiant energy all day long and "leaks" that heat into your drywall and your bedrooms all night.

How a Radiant Barrier Fixes the Second-Floor Sauna A radiant barrier isn’t just more insulation; it’s a thermal shield. By reflecting 97% of the sun’s radiant heat back out through your roof, we stop the heat from ever entering the attic space.

The Result: * Your attic temperature drops by up to 30°F instantly.

• Your upstairs bedrooms stay at the same temperature as your living room.

• Your AC finally gets to "rest," instead of fighting a losing battle against a 140-degree ceiling.
