"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.

"These guys did good job with my crawl space. They had to remove a lot of very moldy insulation in space that was crawl only height. They showed up when they said, confirmed and best of all the price was reasonable. Prices were all over for this job and while theirs was most affordable, the work was well done. Professional and trustworthy. They were also competent, efficient and came with the needed respirator, and Tyvek suit to handle this toxic job. Thanks JImmie!"

Insulation questions, answered by experts

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.
