When the insulation work is completed, most good insulation companies in Santa Clara County in the major cities of Palo Alto, Cuptertino, Gilroy, Campbell, and Morgan Hill will give you a written invoice that details the finished work. This invoice usually will include:

• An itemized list of the gutter protection system and the gutter guard supplies purchased.
• The name, physical address and license number of the contractor.
• A list of all services performed.
• Any applicable warrantees or guarantees provided by the insulation system manufacturers and the company.
• The total cost for insulation services, including the amount due for labor.

It’s a good idea to compare the finished work to what was promised on the written invoice. Ask your company representative to walk through the job site with you and show you the work. Check what was done against the invoice. During the walk-through, ask if there are any special instructions for maintaining your new insulation. If you have questions about the work that was done or the materials used, now is the time to ask.

The majority of good insulation contractors offer some type of warranty on their work or on the materials they’ve used. All warranty details should be provided to you in writing during the contract phase or at the job’s completion. This written warranty information should include the following:

• The contractor’s name and physical address.
• Your responsibility in the case of product failure, including actions you must take in order to redeem the warranty. (i.e., if you have to pay for labor or materials, or if you are required to pay a prorated amount).
• If the warranties are will transfer to the new owner if you sell your home. 
• What products and services are covered. This should also include whether the insulation expert will replace or repair parts in the event of a product failure.
• Terms, limitations and exclusions on the insulation, materials and workmanship.

Q: Why choose a Diamond Certified home insulation company?
A: Diamond Certified helps you choose a home insulation contractor with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only insulation companies rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your new insulation purchase is backed by the Diamond Certified Performance Guarantee.

Q: What’s the purpose of insulating my home?
A: Insulation will keep the house cooler in the summer and warmer in the winter since insulation will resist the flow of heat. Heat, a form of energy, will always look for a cooler area. This means it will flow out of the house in the winter and into the house in the warmer months. If you can reduce the  heat flow, a well-insulated house uses less energy to heat and cool. Insulation will also acts like a sound absorber With so much noise in our environment today, more are soundproofing their houses.

Q: What parts of a house should be insulated?
A: Attics and external walls are not the only places for insulation. Insulation should be put in  other areas of a house, like attics, basement walls, ceilings that are vaulted, floors over unheated garages or porches, and in between internal walls, particularly the bathroom, lofts or floors.

Q: What does u-value mean?
A: U-Value means the amount of the rate of heat loss. The greater the insulating power, the lower the u-value will be. U-value is how insulation is identified and labeled

Q: Where can I find u-value information when I am buying insulation?
A: Insulation manufacturers always print the u-values of their products on labels or bags of the product.  Most of the time, u-values will be printed on the facings of fiber glass batts and rolls.

Q: How can I get the best performance from my new home insulation?
A: The installation of the insulation is the most important ingredient for performance. Regardless of the insulation type, the full u-value can only be achieved with proper installation. Make sure to choose a certified home insulation contractor.

Q: When adding insulation to your home, do you need to remove the old insulation?
A: Since u-values are cumulative, There is no need to remove any current insulation because u-values are cumulative.

Q: Why and how can sound be controlled with the installation of new insulation?
A: The limiting of sound from one area of the house to another requires the application of special insulation plus standard insulation to enclose the noise generating source. Then it forms a sound barrier between the source and the surrounding area. The purposes of controlling sound is to reduce obnoxious noise (like machines), to reduce the noise level, and to provide for good working conditions.

Q: What options do I have when choosing insulation?
A: You can choose from many types of insulations, such as: cellulose, foam, cotton, and fiber glass. For residential homes, the most common types are fiber glass and cellulose.
