In a 110-degree summer, garage insulation matters more than you'd think. Here's when an insulated door pays off.

When homeowners replace a door, the big question is almost always whether to pay extra for insulation. In our climate, the answer is more often yes than in most places. Here is how to decide.

What insulation actually does

An insulated door has a foam core (polystyrene or polyurethane) that slows heat transfer. In Las Vegas that means a cooler garage in summer and a warmer one in winter, plus a quieter, sturdier door, the foam dampens noise and stiffens the panel.

When it's clearly worth it

If your garage is attached to the house, shares a wall with a bedroom or living space, or you use it as a gym, office, or workshop, insulation pays off in comfort and lower cooling load. An uninsulated door turns an attached garage into a heat box that bleeds into the house.

When you can skip it

If the garage is detached and used purely for storage, a non-insulated door may be fine. You are not conditioning that space, so the main benefit (quieter, sturdier door) is nice but not essential.

The resale angle

A new door, insulated or not, is consistently one of the best return-on-investment home upgrades. Insulated doors tend to look and feel more substantial, which helps when selling.
