Regulate Your Home’s Temperature with Professional Insulation from Sensigreen
Because Sensigreen started as an insulation company and grew into a full HVAC contractor, we treat your home as one connected system. Properly installed insulation helps your home hold its temperature, so your equipment runs less and every room feels more consistent.
How Home Insulation Lowers Energy Use
Insulation works by
slowing heat transfer through walls, floors and ceilings
. In summer, attic heat pushes down into your living space, and in winter the warmth you paid for escapes upward. The better your home resists that movement, the less your air conditioner and heating system have to work.
Air sealing is the other half of a good insulation job.
Gaps around wiring, plumbing, lights and attic hatches let humid air and dust slip past even thick insulation, so every Sensigreen project starts by sealing those leaks.
Understanding R-Value
R-value measures resistance to heat flow, and higher is better. The
recommended R-values for Alabama and Georgia homes
in Climate Zone 3 are roughly R-30 to R-60 in attics and R-13 to R-15 in 2×4 walls, according to ENERGY STAR, yet many older homes in our area fall well short. Looking at
how spray foam, cellulose and fiberglass compare per inch
, closed-cell spray foam leads at about R-6 to R-7, open-cell foam and cellulose fall near R-3.5 and fiberglass ranges from about R-2.5 to R-3.5. Installation quality and air sealing matter just as much as the number on the bag.

Types of Insulation We Install
No single product fits every home, so we install three proven materials and match each to your house, goals and budget.
Spray Foam Insulation
Spray foam is where Sensigreen began. Our SucraSeal spray foam insulation expands to fill gaps and irregular framing, insulating and air sealing in one step. When choosing
open-cell vs. closed-cell spray foam
, open-cell is flexible and sound-dampening, ideal for rooflines and interior walls, while closed-cell is denser, offers more R-value per inch and blocks moisture. Its
best uses include attics, crawl spaces and rim joists
, where air leaks are hardest to stop.
Cellulose Insulation
Cellulose insulation is an
eco-friendly recycled material
made largely from paper treated to resist fire, mold and insects. It packs tightly around framing and wiring, and
dense-pack cellulose for existing walls
lets us insulate finished walls through small access holes without tearing out drywall.
Fiberglass Insulation
Fiberglass insulation is non-combustible, moisture resistant and affordable.
Blown-in fiberglass for attics
is one of the fastest ways to reach recommended levels, while
fiberglass batts for open walls and new construction
are an economical choice when framing is exposed. We fit every batt carefully, since gaps and compression are why fiberglass underperforms.
Choosing the Right Insulation for Your Home
Comparing
spray foam vs. cellulose vs. fiberglass on cost, R-value and lifespan
, fiberglass usually costs the least, cellulose excels in existing walls and spray foam costs more upfront but adds air sealing and never sags or settles. Many homes benefit from a combination. Learn more in our insulation FAQs.
Attic Insulation
Most homes lose more energy through the attic than anywhere else, which makes it the best place to start.
Signs Your Attic Needs More Insulation
Watch for
hot upstairs rooms and uneven temperatures
,
rising summer cooling bills
and an air conditioner that runs nonstop on hot afternoons. Look across your attic floor, too.
Insulation below the tops of your ceiling joists
means you have less than recommended. Stains, damp insulation, musty odors or droppings point to
moisture, mold or pest damage
that usually requires removal. Fixing the attic first can also help us size a new air conditioner correctly if you need one.
Our Attic Insulation Process
We begin with an
attic inspection and energy assessment
, measuring existing insulation and checking for leaks, moisture, pests, ventilation and duct issues with help from our NATE-certified HVAC technicians. When needed, we handle
old insulation removal and cleanup
with commercial vacuum equipment. Next comes
air sealing leaks before insulating
, followed by
installation and a final walkthrough
so you see exactly what was done.
Attic Insulation Upgrades vs. Full Replacement
Topping off existing insulation
is the most affordable option when current insulation is dry and clean but too thin.
A full removal is needed
when insulation is wet, moldy or rodent-contaminated, or when you are switching to roofline spray foam. We will tell you honestly which one your attic needs.
Whole-Home Insulation Services
Our home insulation services cover the entire building envelope, not just the attic.
Wall Insulation
We specialize in
insulating existing walls without major demolition
using dense-pack cellulose, and we provide
new construction and remodel wall insulation
with spray foam or fiberglass batts before drywall goes up.
Crawl Space & Underfloor Insulation
Vented crawl spaces pull in humid Southern air for much of the year. Closed-cell spray foam or properly supported fiberglass is effective at
stopping cold floors and ground moisture
beneath your home.
Basement & Rim Joist Insulation
The rim joist is
one of the biggest hidden air leaks
in many homes. Closed-cell spray foam seals and insulates it in one step, stopping drafts and pest entry.
Garages, Bonus Rooms & Rooms Over Garages
Insulating floors, knee walls and sloped ceilings is the key to
making hard-to-cool spaces comfortable
and bringing bonus rooms in line with the rest of your home.
Insulation Removal & Replacement
Damaged, wet or rodent-contaminated insulation
can no longer protect your home and may affect indoor air quality. We remove it safely, clean the area, seal leaks and install fresh insulation.
Money-Saving Benefits of Professional Insulation
Lower Monthly Energy Bills
A well-insulated home means
reduced HVAC runtime and wear
, lowering utility bills and extending equipment life. Insulating first also supports
right-sizing HVAC equipment
, so if you are planning a heating or cooling replacement, your new system can be sized for your improved home.
Year-Round Comfort & Healthier Indoor Air
Sealing the envelope delivers
better humidity control
, so rooms feel cooler and drier at the same setting. It also means
fewer drafts, allergens and pest entry points
. Pair insulation with duct cleaning for an even bigger improvement.
Long-Term Value for Your Home
Documented upgrades offer
higher energy efficiency at resale
, which appeals to buyers watching monthly costs. Ask us about
local utility rebates
that may apply, and explore our financing options and current special offers.

Home Insulation FAQs
How Much Does Home Insulation Cost?
Cost depends on the area, insulation type, target R-value and whether old insulation must be removed. Blown-in fiberglass and cellulose are generally most affordable, while spray foam costs more but adds air sealing. A free assessment gives you an exact price.
What Type of Insulation Is Best for My Home?
Blown-in fiberglass or cellulose suits most attic floors, dense-pack cellulose works well in existing walls and spray foam excels in rooflines, crawl spaces and rim joists. Many homes benefit from a combination.
Is Spray Foam Better Than Cellulose or Fiberglass Insulation?
Spray foam offers the best air sealing and highest R-value per inch, but cellulose and fiberglass often deliver better value in open, accessible spaces when paired with air sealing.
Which Insulation Is Best for Attics in Alabama & Georgia?
For most attics, air sealing plus blown-in cellulose or fiberglass to about R-30 to R-60 is proven and cost-effective. If ductwork runs through the attic, roofline spray foam may be the better choice.
How Long Does Insulation Installation Take?
Many attic projects are finished in one day. Larger jobs involving removal, walls or whole-home spray foam may take longer, and we include a timeline with your quote.
How Do I Know If My Home Is Under-Insulated?
Uneven temperatures, high bills, drafts, cold floors and visible attic joists are common signs. See our insulation FAQs for more.
