"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

Insulation questions, answered by experts

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

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.

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.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.
