"I can't say enough good things about Elephant Floors. They removed carpet and parquet flooring and installed new hardwood floors in a large space (~1200 square feet) plus a flight of stairs, the entrance way and a closet. The wood is perfectly laid - seamlessly moving among three rooms with long lines. They kept the house really clean and neat, moving my furniture around, so I didn't have to move it. They did this start to finish in 4 days, my friends and neighbors are amazed - lots of excellent feedback..and this includes a contractor, who does this himself. Thank you Daniil, Hector and team, Bravo!"

FAQs for batt, rolled or reflective insulation install or upgrade projects in Gilroy, CA

Your radiant barrier can last up to 80 years or more with minimal maintenance and care. Factors like the quality of the materials you choose and proper installation affect its actual lifespan. Hiring a radiant barrier professional ensures that it's installed correctly to prevent exposure to moisture and other elements, which will help extend its effectiveness.

Installing a radiant barrier in your home offers several benefits that improve energy efficiency and can lower your electricity bills. Mainly, it reduces cooling costs by reflecting heat away from your home, helping to maintain lower indoor temperatures. In the winter, it can help keep warm air from escaping. This reduces the stress on your HVAC system, potentially extending its lifespan and reducing energy consumption. 

Additionally, a radiant barrier can protect roofing materials and structural components from extreme temperatures. Pairing your radiant barrier with other insulation systems will provide even more benefits.

A professional installation of a radiant barrier takes one to two days, while a DIY project, due to its complexity, extends the process into several days. The installation duration depends on the size of the attic and the chosen method. For larger homes, experts complete the work in two to three days. Laying foil over existing insulation is a faster procedure that maintains high performance, ensuring the barrier operates efficiently.

A radiant barrier must be installed over existing insulation rather than directly underneath it, ensuring that an effective air gap is created for optimal heat reflection. An adequate air space on at least one side permits the reflective surface to work at peak efficiency, reflecting heat away from the home and preventing moisture issues. This placement method enhances insulation performance and maintains structural integrity by reducing heat transfer and condensation risks, ultimately preserving the quality of both the barrier and insulation.
