"Triangle Radiant Barrier did a great job installing radiant barrier in our unfinished storage and attic. I was pleased with the whole process from the beginning where all the options for treatment were clearly explained, to the professionalism of crew who did the install, and to the final inspection. The insulated zipper door for the attic stairs is great so I don't have insulation falling down every time I touch the pull-down ladder."

Tony was especially helpful in explaining the available options and recommending the solution that best fit my garage and specific needs. He was knowledgeable, professional, and even managed to fit me into his schedule on short notice, which I greatly appreciated."

We were extremely concerned about what damage it can cause and Jimmie educated us on what was going on and the options to address the problems. He answered all of my questions. He fixed all issues we had and worked quickly to prevent damage to our home structure. It was a pleasure working with him.”"

"Jimmie was professional, friendly and knowledgeable. Of the estimates and recommendations I received for mold remediation in my crawlspace, I thought Jimmie's approach seemed the most logical and thorough. Pricing was fair, and the service was prompt with regular communication from him and his team about progress and next steps. He even performed an extra preventative measure that wasn't included in the estimate. I highly recommend this company."

Insulation questions, answered by experts

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.
