What’s in
your attic?
Your home has aged. Has your insulation kept up? Learn how the space above your ceiling affects comfort, energy use, and the money you spend keeping your home comfortable.
A comfortable home
starts with a better barrier.
Heat moves from warmer areas toward cooler ones. In summer, a hot attic can send heat into your living space. In winter, heat from your home can move into a colder attic.
Insulation slows that heat transfer. Air sealing addresses the gaps that let air move between the house and attic. Together, they help your heating and cooling system maintain a comfortable temperature with less wasted energy. [1][2]
Conduction
Heat travels through materials, such as the layers between your attic and ceiling. Insulation adds resistance along that path.
Convection
Moving air carries heat. Gaps around penetrations and attic access points can let conditioned air escape.
Radiation
Heat travels as radiant energy, including from the sun to the roof and between hot roof surfaces and the attic below. [1]
Texas Panhandle
Conditions
Summer heat. Persistent wind. Freezing winter nights. Your attic sits between you, the brutal weather of the Panhandle, and the comfort inside your home. Insulation and air sealing help your home handle all three.
Summer heat builds overhead.
Panhandle attics can reach 130°F or more in the summer. The sun soaks into your roof causing it to retain lots and lots of heat. This heat is radiated into your attic and without a proper barrier in place that heat will radiate into your home.
Proper insulation in your attic slows the transference of energy from your conditioned space into your attic and vise versa. It's going to be hot in your attic but that insulation barrier will keep your conditioned air where it belongs and protect you from the elements.
Wind finds the weak spots.
Wind creates pressure differences around a house, pushing air through openings. Near attic edges, air moving through or around unprotected insulation can weaken its performance. This is called wind washing.
Airflow can also disturb loose insulation, leaving thin edges even when the center looks deep. A continuous ceiling air barrier and protected insulation edges help limit these losses while keeping intentional attic ventilation open.
The same barrier works year-round.
In summer, insulation slows heat entering your cooled home. In winter, it slows heat escaping from your heated rooms. The greater the temperature difference across the ceiling, the stronger the drive for heat to move.
Insulation adds resistance in either direction and helps your heating and cooling system maintain comfort and lifespan. A proper insulation barrier allows your HVAC to work instead of struggle. This not only saves energy and money but future headaches of having to repair or replace HVAC components unnecessarily.
What about freezing weather and power outages?
Protect exposed pipes.
Water pipes exposed to freezing attic temperatures need appropriate freeze protection. Ceiling insulation protects the rooms below; it does not keep an unconditioned attic warm.
Watch for ice dams.
Snow can melt over warmer roof areas and refreeze at colder edges, creating an ice dam. Heat escaping into an attic can contribute to this uneven melting.
Plan beyond insulation.
Insulation slows indoor temperature change during an outage. It does not replace heating, cooling or an emergency safety plan but will help keep your heat in longer in case of.
Where is your home’s
energy going?
Your heating and cooling system works to keep your home comfortable. Every weak spot in the home’s outer boundary can make that job harder.
Above the ceiling
Thin, uneven, or missing attic insulation allows more heat to move between the attic and your rooms. Gaps around the attic hatch and ceiling penetrations can also leak air.
Through walls and floors
Empty wall cavities and floors above unconditioned spaces can weaken the insulation layer around your living space.
Around windows and doors
Glass and frames transfer heat, while worn weatherstripping and unsealed gaps can let outdoor air in and indoor air out.
Through leaks and ductwork
Air leaks connect your living space to outdoors or unconditioned areas. Leaky ducts in an attic can lose heated or cooled air before it reaches your rooms. [2]
Older homes.
A reason think about what's in your attic.
Your home may have been built to the standards of its time. That in itself begins to paint the picture of your insulation.

More resistance.
Means less energy can escape
R-value
: a measure of resistance to the flow of heat through a given thickness of a material (such as insulation) with higher numbers indicating better insulating properties
Compare the insulation layer
Same area. Same temperature difference. Compare idealized conduction through insulation alone against R-10.
75%less heat flow through this insulation layer in the example.
This is an insulation-only comparison, not a prediction of bill savings. Real ceilings also include framing, other materials, gaps, and air leakage. Model: heat flow is proportional to 1 ÷ R-value.
An R-value is a measure of a material’s thermal resistance
specifically, how well it resists the conductive flow of heat within a home. This is the center everything insulation and what matters the most. With a professional install of the right R-value you'll see results almost immediately in your homes ability to maintain a conditioned environment and over time you'll see results in the form of savings on your energy bills.
Core Concepts
Meaning: The “R” stands for resistance. It evaluates how effectively an insulating material, window, wall, or ceiling impedes heat transfer (both heat loss in cold weather and heat gain in hot weather).
The Rule of Thumb: Higher R-values indicate greater insulating power and better energy efficiency.
How local building codes fit into the decision
Code requirements depend on the jurisdiction, work being performed, and the approved compliance approach. Amarillo lists the 2015 International Energy Conservation Code with local amendments. Lubbock has adopted the 2021 edition with amendments; its amended prescriptive table lists R-38 for ceilings in climate zone 3. Exceptions and alternative compliance paths can apply. [5][6]
We choose the scope for your home and check the requirements that apply to your project. R-40 is not a universal legal requirement across the service region.
Air sealing, ventilation,
and Moisture
Insulation slows heat transfer. Air sealing closes unwanted air paths. Ventilation gives air and moisture a planned way out. Getting these details right helps the whole attic work together.
Seal the ceiling.
Gaps around ceiling openings and the attic hatch let air move between your rooms and the attic. Addressing those paths before adding insulation helps keep conditioned air inside the home.
Think of the air barrier as a continuous lining: the edges and connections matter just as much as the surface. More insulation alone does not close those gaps.
Keep ventilation open.
In a vented attic, insulation needs to stay clear of the intended air intake at the eaves. Baffles maintain a channel near the roof deck. An adjacent dam keeps insulation from spilling into the opening or being disturbed by airflow.
Vent placement and the amount of usable open area matter. A working ventilation arrangement takes more than simply adding more holes.
Give moisture a way out.
Moisture is a natural enemy to fiberglass insulation. Attic vents are part of the air and moisture plan. Bathroom and kitchen exhaust have their own jobs, too. Their routes need to remain functional when air sealing and insulation work is done.
The goal is to close unwanted leaks while preserving the airflow the home needs, including combustion air and whole-house ventilation.
The attic hatch needs both.
Insulation slows heat moving through the lid. Perimeter gaskets and a reliable closure help stop air leaking around it. A dam around the opening holds loose-fill insulation in place while keeping the access usable. This is only necessary if your attic access is inside the conditioned space of your home.
The right seal for each opening.
Chimneys, flues and other hot components need approved clearances and appropriate sealing materials. These connections must preserve fire protection, exhaust and air supply. One type of foam is not the answer for every gap.
Know what happens before the insulation goes in.
We have the ability to seal up many gaps and openings you don't even know exist in your ceiling. These gaps and openings are directly responsible for energy loss in your home along with the improper insulation. We can go into your attic find these hard to reach places and seal them up with a fire resistant foam that doubles as an energy stop.
Keep comfort in.
Keep costs in perspective.
The opportunity depends on where your home starts. A nearly bare attic and a well-insulated attic will not respond to the same upgrade in the same way.
The assumed reduction percentage all depends on how much insulation you have currently to how much we have to put in. If your attic is relatively new then a top off might be all that is required. You might have 8 good inches of still visibly stable insulation which would only require us to add 5 or 6 inches on top of that. You'll see a marginal savings.
In really dire situations where there is little to no insulation it is absolutely necessary to add insulation. In an instance like this it would be a change like you never had insulation to begin with. You would see the highest reduction in energy costs in this situation.
The older your home the higher chance that you have a situation that is in dire need of addressing. If your home was built in the 1900s and you're wondering why your bills are so high this could be a huge factor.
Explore possible annual savings
About $23 a month in this 15% example.
ENERGY STAR estimates an average 15% reduction in heating and cooling costs from a package of whole-home air sealing and added insulation in attics, floors over crawl spaces, and accessible basement rim joists. That is a national modeled average for combined improvements—not a promise for attic insulation alone. [7]
This calculator lets you explore an annual dollar example. Enter only the portion of your annual energy costs used for heating and cooling. Your whole utility bill also includes appliances, lighting, and other uses.
Selected percentages are scenarios, not predicted results or a savings range for your home. Calculation: annual heating and cooling cost × selected percentage. This is not a quote, payback estimate, or financing offer.
Start with what
your home needs.
A chilly/hot room, a draft you notice. Built in the 1900's. Brown and dirty insulation. If you can see the rafters in your attic when you put your Christmas tree up. These are all good reasons to look at your situation closer.
Look at the whole picture.
We check the insulation’s depth and coverage, along with accessible air leaks and visible condition issues. The age of the house helps start the conversation.
Choose practical work.
Your home may need a top-off, a fresh installation, or other work first. We explain the options and work with you to find a practical starting point.
Make comfort a priority.
This side of the business is our heart. We’ve spent our lives serving the Texas Panhandle, and we want to help you keep more comfort—and more of your money—at home.
