Q: What's the best insulation for a garage?

• <div><p>Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation. </p></div>

Q: Is ceiling insulation worth it?

• <div><p>Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2. </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 most affordable way to insulate behind drywall?

• <div><p>The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around <b>$0.75 per linear foot</b>, with the width matching the gaps between standard studs perfectly. However, it&rsquo;s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn&rsquo;t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.</p></div>

When installing board and batten siding, make sure there is wall sheathing and 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’t plywood or OSB, you can install vertical furring strips at 1½- to 2-foot intervals to nail the boards and battens to.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
