I trust them with all commercial and residential insulation projects. I worked with Noble on multiple occasions and highly recommend them especially for spray foam insulation.Posted on Google Yashua BarrettTrustindex verifies that the original source of the review is Google. Rami really knows his stuff and his crew is very professional. I am impressed by the teams response time and attention to detail when it comes to the install. I like the fact that he sources Knauf insulation, it’s a little more natural and really helps the air quality in the home!! I was also very impressed by the foamers quality of work and mindfulness when it came to safety. Great team and I highly recommend!!Posted on Google maurissa heffranTrustindex verifies that the original source of the review is Google. Best insulation company we have used...and we've used several on different job site's. Professional, knowledgeable, reasonable, clean and a real pleasure to do business with. He delivered on every promise. I asked advice on heat and soundproofing he went over and above to get it done at our building. We are very pleased and will use them again. Thanks guys for the great job!Posted on Google Mickey SouzaTrustindex verifies that the original source of the review is Google. As a HERS verifier, I come across a lot of insulators, and would avoid some with a 10 foot pole. Insulation is an art, and the crews at Nobel Insulation know their art. R-Values, proper coverage, heating of the spray foam chemicals, safety, materials... all of it. Not only that, they are honest and care about their work and what it does for the planet -- which is what works to make a building energy efficient.Posted on Google Roland De WolkTrustindex verifies that the original source of the review is Google. An exceptional experience. Not only the lowest of five bids from highly recommended energy audit professionals, but an unusual pleasure to deal with. Always responsive, flexible, forthright. They did an extensive job in two days, no change orders (the low big I received 6 months before is what they charged me when the outstanding work was done.) Rami, Hector & Co. were truly outstanding.Posted on Google Brett WeiselTrustindex verifies that the original source of the review is Google. Noble did a fantastic job for us. Did a quality job at a very reasonable price would highly recommend them.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Noble Insulation are licensed and experienced insulation contractors in Oakland, CA. We specialize in open-cell and closed-cell spray foam insulation. This material is far superior to fiberglass and cellulose. Here is a breakdown of each material:
With this form of spray foam, the cells are intentionally left open. This makes the foam softer and more flexible. By doing so, the foam expands more than it otherwise would with closed-cell spray foam. This means you can use less material to fill the same amount of insulation space. Subsequently, this can reduce the cost of materials during insulation. One major benefit of open-cell spray foam is that it offers better noise control (meaning it creates a quieter environment) than closed-cell spray foam.

This is widely regarded by industry professionals as the best material available for consumers. It has an R-value of 7.0 per inch. (R-value measures thermal resistance and is an indicator of the overall insulating power of a material.) To put that in perspective, open-cel spray foam and other alternative options such as fiberglass and cellulose generally offer less than a 4.0 per inch R-value. Subsequently, clients in Oakland, CA who choose closed-cell spray foam enjoy more energy savings monthly and reduced maintenance costs. Closed-cell spray foam lasts for more than 75 years.

We offer a range of insulation services in Oakland, CA. These services include air sealing, attic insulation, crawl space insulation, metal building insulation, and energy audits. Below is more information about each service.

We provide crawl space insulation in Oakland, CA for residential and commercial preporties. This notably includes spray foam insulation for your crawl space area (and other vulnerable areas around the perimeter of your home). Reliable insulation for your crawl space helps reduce energy costs, improves air quality, and reduces the risk of pest infestation (among other benefits). Noble Insulation has years of experience with crawl space insulation in Oakland, CA as well as the rest of the Bay Area.
We provide insulation services for vented and unvented attics in Oakland, CA. This reduces the risks of drafts, water damage, and temperature fluctuations inside your home. It can also help prevent pest infestation and subsequent damage to your attic, roof, and property foundation.


Air sealing services with Noble Insulation involve the identification of cracks, gaps, and other openings where unwanted air can penetrate and enter your home; heating and air from your HVAC unit can also leave these same areas and lead to it running all day and night. This can lead to high energy costs. We offer spray foam insulation, radiant barriers, and more to ensure your home and commercial property are as energy efficient as possible.
There are many purposes for metal buildings. From serving as warehouse and storage facilities to mancaves, a metal building can be used in so many ways. Regardless of your purpose for your metal building (or the size of your metal building), Noble insulation can ensure it has the insulation material it needs to remain in good condition with optimal temperature regulation. Get in touch today to learn more about metal building insulation in Oakland, CA from Noble Insulation.

Spray foam offers unique advantages that alternative solutions do not provide to the same extent. Notably, these benefits include:

Spray foam simply lasts much longer than fiberglass and cellulose. When you compare the options, spray foam lasts between 50 and 90 years, whereas fiberglass and cellulose last between 20 and 30 years on average.
Upgrading your home’s insulation with spray foam can save you approximately 15% on energy costs. This is a substantial amount that largely (if not entirely) makes up for the initial investment for the upgrade.
Since spray foam provides a much more reliable thermal barrier, you can trust that no unwanted air or contaminants enter your home and affect the comfort level and/or air quality.
You can also reduce the risk of pest infestation in your attic, crawl space, and other vulnerable areas by upgrading to spray foam insulation.


Energy audits are a great way to learn more about your property’s energy efficiency. If there are any issues that are holding back your property’s thermal resistance and temperature control, then we will promptly identify them and put a plan in place to ensure they are resolved. This includes the detection of leaks, cracks, gaps, and holes that allow outdoor air to enter your property and indoor air from the HVAC unit to escape. Through an energy audit with Noble Insulation, you can ensure your property has good air quality, optimal comfort, and optimal temperature regulation.
