"Matias and his crew were excellent! They blew new insulation in my attic for me, and I am thrilled with the result. They ran into an issue accessing part of my attic, but thanks to their creative problem-solving, they worked around it and were able to get insulation throughout the whole attic. They truly went above and beyond, and I would recommend them to anyone who needs insulation work done."

Insulation questions, answered by experts

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.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.
