The sun has gone down. The temperature outside is finally dropping. But inside your house, it still feels like the heat of the day refuses to leave.
That’s an Arizona problem many homeowners know well.
And part of the reason may be sitting directly above your ceiling.
Your Attic Has Been Baking All Day
Think about what your roof goes through during an Arizona summer.
For hours, the sun beats down on it. The roof absorbs heat, and the attic underneath becomes an extremely hot space.
Then evening arrives.
The sun disappears—but all that accumulated heat doesn’t magically disappear with it.
Your attic and the materials surrounding it can continue transferring heat long after sunset.
That means your AC may still be fighting the effects of the afternoon sun well into the evening.
Insulation Is the Barrier Between That Heat and Your Home
Attic insulation helps slow the movement of heat between your attic and the conditioned rooms below.
When insulation is too low, uneven, missing in areas, or no longer providing adequate coverage, more heat can make its way toward the living space.
That’s one reason a home can remain uncomfortable even after the outdoor temperature starts dropping.
Your AC isn’t just cooling the air.
It’s fighting heat that has been building above your ceiling for hours.
Arizona Homes Need the Right Amount of Insulation
Simply having insulation in your attic doesn’t necessarily mean you have enough.
If the insulation level is low enough that attic framing is clearly visible throughout large areas, or there are thin and uneven sections, it may be time to have it evaluated.
At Active Shield Insulation, we use Johns Manville Climate Pro® blown-in fiberglass insulation for our blown-in applications.
We can add insulation to an under-insulated attic or, when necessary, completely remove old material, address minor air leaks, and install new insulation.
Don’t Let Today’s Heat Follow You Into Tonight
Your home should be the place where you escape the Arizona heat—not where you continue feeling it hours after sunset.
Proper attic insulation can help reduce heat transfer, improve comfort, and help your cooling system do its job more efficiently.
So the next time the sun goes down but your house still feels hot, don’t just look at the thermostat.
Look above it.
