"These guys took time from their busy schedule came to my residence on Easter Sunday to give me a price on repairing insulation mess left by previous contractor. They arrived next day and completed the insulation work and did an excellent job at an excellent price. My thanks to Sagittarius air seal thanks again, Michael Duffy."

"I can?t say enough good things about PeakPro Insulation! Before they came out, my attic wasn?t insulated at all and my house constantly fluctuated in temperature. When their team arrived, they introduced me to solar radiant barrier insulation. The difference was noticeable immediately. After the job was done, every room in my house finally felt consistent in temperature, and even my attic felt cooler while they were working up there. On top of that, they left the attic looking beautiful and clean. Highly recommend"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.
