"Well, the was too much on the second floor but Aladdin solved that with blown insulation. I look forward to the cool savings in the summer and warm savings in the winter. The house has not added insulation since it’s manufacture in 1989. We have been here for 4 years. Should have done it four years ago. Thank you Aladdin!"

Drywall Insulation FAQs, answered by experts

Yes, drywall can hold a 50-pound TV. However, when mounting a TV, you’ll either need to attach it to wall studs or use drywall anchors. If you use anchors, make sure to buy a type that can hold at least 50 pounds. Molly bolts, threaded anchors, and toggle bolts are all good options. For extra support, you can also install a wall mounting plate with the anchors.

Some textures are easier than others to DIY, but the short answer is yes, you can absolutely texture walls yourself. You’ll need certain materials, like a trowel or paint sprayer, but the most important things you’ll need are patience and time. DIYing wall texture can save money and be a fun, messy project, but homeowners need to know that adding texture to a wall isn’t a quick project. 

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Most load-bearing walls are exterior, though they can also be interior.
