"⭐⭐⭐⭐⭐ Excellent Work by Sebastian – Jersey State Insulations We recently had insulation work completed by Jersey State Insulations, and Sebastian and his team did an outstanding job. From the beginning, Sebastian was professional, knowledgeable, and very easy to work with. He took the time to explain the process, recommended the right insulation for our space, and made sure everything was properly sealed and installed. The workmanship was clean, efficient, and done with great attention to detail. No shortcuts — just solid, quality work. Sebastian was punctual, respectful of our home, and left the area clean after the job was finished. We’ve already noticed an improvement in comfort. I highly recommend Sebastian and Jersey State Insulations to anyone looking for reliable and professional insulation services."

Metro NY Insulation is a green focused, cellulose insulation contractor that works with homeowners to help them save money on their heating and cooling costs. By sealing the home to prevent drafts from allowing heated (or cooled) air from escaping, home works more efficiently and uses less energy. We are accredited by the Building Performance Institute (BPI) for Building Envelope and Building Analyst to view the whole building as a system and allow it to breathe properly while still retaining the heat in the winter and the conditioned air in the summer. Proper ventilation and insulation leads to a healthier home, with fewer mold issues and less likelihood of developing ice dams in the winter. We do more than just add insulation, we do full scale weatherization to keep you and your home healthy. \n\nWe also do interior wall soundproofing to reduce noise transfer from room to room.\n\nWe use only 100% Borate infused National Fiber Cel-Pak so you won't have to worry about the toxic off-gasing or ammonia smell from inferior insulation used by other companies.\nAll employees are trained and trusted. NO SUBCONTRACTORS. Free in-home assessment. Costs are determined by the scope of the job - we do everything to the BPI specifications. \nWe do more than just insulate - WE WEATHERIZE!!!

Insulation questions, answered by experts

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

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.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.
