Q: Do you need a vapor barrier when drywalling a garage?

• <div><p>If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.</p></div>

Q: What do you put behind board and batten siding?

• <div><p>When installing board and batten siding, make sure there is wall sheathing <i>and</i> a moisture-resistant barrier installed. Behind that sheathing should be plywood or OSB for you to nail the boards and battens into. If there isn&rsquo;t plywood or OSB, you can install vertical furring strips at 1&frac12;- to 2-foot intervals to nail the boards and battens to.</p></div>

Q: What is the best type of insulation for crawl spaces?

• <div><p>Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.</p></div>

Q: Do professionals handle attic, wall, and floor insulation?

• <div><p>Yes, professionals install and upgrade insulation for all home or business areas.</p></div>
