I highly recommend EM Energy & Air!! We had them remove and replace our attic insulation, clean and sanitize our attic and install new insulation and a heat shield in our home. The crew was awesome. They laid down plastic for the pathway, and around the entire area where work was to be performed. It took about 5 hours and they were non-stop working to completion. We got a few quotes and were well worth our cost. Can’t say enough good things about the entire process, from initial meeting, quote to work completed!!

As a Professional Engineer and HVAC business owner, I can certainly recommend E&M. I pursued multiple bids and Eilon was by far the most knowledgeable, thorough and professional. His field team was courteous, worked neatly, and finished the project on time. We already notice that the HVAC system runs less and the house holds temperature better. Strong endorsement from me.

we are very pleased having hired EM Energy & Air trough Eilon to tackle our attic project. From scheduling an appointment to getting the job done all went smoothly and faster than we expected. After reaching out on Sunday our attic got renovated within 1 week time frame: removing the old insulation, clean up of the attic, installing a whole house fan, redoing the HVAC pipes and insulation. I am very pleased with work done and professionalism of the crew. They worked very clean and swiftly ( all work was done in 1 day).

I recently hired EM Air & Energy to clean up and re-insulate my attic and handle some heating work at my home. I’m thrilled with the results and highly satisfied with their service! Elion visited my home to assess the attic and heating setup. He was thorough, knowledgeable, and gave me valuable suggestions tailored to my needs. The contractors who came to do the actual work were efficient, hardworking, and professional throughout. The pricing was fair, and I truly feel I received excellent value for the cost. The entire process was seamless, and I’m happy to recommend EM Air & Energy to anyone looking for top-quality service.

I called up these folks initially to get an estimate to clean out my attic. They provided me the best bid I received in terms of details and price. After a candid conversation with Eilon, I decided to have EM energy and air also install new insulation and seal off my attic. The crew were very thorough in sealing off all the possible rodent entry points and did a great job with the cleaning. And the insulation came just in time for the heat wave. It made a 10 degree difference in the inside temperature of my home. Great experience, would highly recommend them.

Installing two heat pump with EM was a breeze; communication was very timely and the job was done well and as agreed. Quote process: They got me a fair quote same-day by just from sending them info over text (while other companies took weeks) and the price was fair. Change orders: I decided later I want two units, and again it was a smooth process. Also later there was an equipment change – and it made it convenient for me. Job Day: 4 guys arrived as agreed and get it done same day. I talked to most of them and all were polite, nice and upbeat. They let me inspect the work closely, made sure I am happy and give me tips on next steps. TLDR; Would hire them again and I am happy to recommend to my neighbors!

What Is a Radiant Barrier?
A radiant barrier is a specialized reflective material designed to block radiant heat from entering your home. Unlike traditional insulation, which slows down heat transfer, a radiant barrier reflects heat away from your home before it can be absorbed by attic insulation. Installed along the underside of your roof, this barrier significantly reduces the amount of heat that builds up in your attic, helping to keep your entire home cooler.
In Palo Alto, where warm summers can lead to excessive indoor heat, radiant barriers work in conjunction with attic insulation to maximize energy efficiency. Instead of allowing heat to accumulate and transfer into your living spaces, a radiant barrier prevents this process, reducing your dependency on air conditioning.
How Does a Radiant Barrier Work?
Heat moves in three ways. Conduction happens when heat transfers directly through solid materials like walls or roofing. Convection occurs when heat moves through the air, such as when warm air rises inside a home. Radiation sends heat in the form of infrared energy, which explains why the sun heats an attic so quickly.
A radiant barrier specifically addresses radiant heat transfer by reflecting it away before it can reach the insulation below. Since most roofs absorb and radiate heat downward, a radiant barrier disrupts this process, reducing attic temperatures by as much as 30°F in some cases.
The Radiant Barrier Installation Process
Attic Inspection and Preparation
Before installing a radiant barrier, our team conducts a thorough attic inspection to assess existing insulation, ventilation, and any potential problem areas. If your attic lacks proper airflow or has insulation that needs replacing, we address these issues first to optimize overall energy efficiency.
Choosing the Right Radiant Barrier
There are two main types of radiant barriers, foil-based and radiant barrier coatings. The former are thin sheets of aluminum foil, either perforated or solid, that reflect heat effectively. The latter is a reflective spray applied to the underside of the roof deck, offering similar heat-blocking properties.
For most folks who need a radiant barrier in Palo Alto, foil-based barriers provide the best results, as they are highly reflective and easy to install with minimal disruption to your attic space.
Installing the Radiant Barrier
Our team installs the radiant barrier along the underside of the roof rafters to make sure we cover the full attic. Proper spacing and ventilation are key to allowing heat to escape while preventing trapped moisture, which could reduce effectiveness over time. We secure the material without obstructing airflow, allowing your attic to breathe while maximizing heat reflection.
The Benefits of Installing a Radiant Barrier
Lower Cooling Costs
By reducing the amount of heat that enters your home, a radiant barrier significantly decreases your need for air conditioning. Homeowners often experience energy savings of 10-15% during the hottest months, as their HVAC systems don’t have to work as hard to maintain comfortable indoor temperatures.
Improved Indoor Comfort
Without a radiant barrier, attic heat builds up throughout the day, transferring into your home and making it harder to keep cool. With a properly installed barrier, temperatures remain more stable, leading to a more comfortable living environment year-round.
Extended HVAC System Lifespan
Since your air conditioning system won’t have to work as hard to cool your home, it experiences less wear and tear over time. This can extend the lifespan of your HVAC system, reducing the frequency of repairs and replacements.
Better Home Energy Efficiency
A radiant barrier improves overall home energy efficiency by reducing heat gain. This is especially important in Palo Alto, where sunny weather can contribute to high attic temperatures. Paired with high-quality insulation, it creates a more energy-efficient home with lower environmental impact.
Works Well With Other Insulation Solutions
Radiant barriers complement traditional insulation rather than replacing it. While insulation slows heat conduction, a radiant barrier prevents excessive heat from reaching insulation in the first place. Together, these two elements create an optimized energy-saving system for your home.
Does Your Home Need a Radiant Barrier?
If your home tends to heat up quickly in the summer, or if your cooling system struggles to keep up, a radiant barrier can be a game-changer. Homes with south- or west-facing roofs that absorb direct sunlight throughout the day benefit the most from this technology.
You may also want to consider a radiant barrier installation if:
- Your attic becomes unbearably hot in warm months.
- Your energy bills spike dramatically in the summer.
- You notice uneven cooling, with some rooms staying hotter than others.
- You’re looking for cost-effective ways to reduce HVAC strain.
