Exterior Insulation Installation
in Madison, AL
Madison Pro Siding & Wrap has installed continuous exterior insulation on new construction and full re-siding projects throughout Madison, AL for over 20 years, and demand for it has grown as more homeowners look to cut cooling costs during the region's long, humid summer season. Continuous rigid insulation installed beneath siding can improve a wall assembly's effective R-value by 20% or more by eliminating thermal bridging at wall studs, where standard cavity insulation alone can't stop heat transfer through the framing itself. Madison's energy code increasingly favors continuous insulation on new construction to meet updated thermal performance targets, particularly on homes with standard 2x4 or 2x6 wood-frame walls. We install rigid foam board systems, including XPS, EPS, and polyisocyanurate insulation, matched to each project's R-value target and siding type.
Homes with continuous exterior insulation typically see a measurable reduction in cooling costs compared to homes relying on cavity insulation alone, since eliminating thermal bridging addresses a source of heat transfer that cavity insulation can't reach. The upgrade also reduces exterior wall condensation risk in humid climates like Madison's when installed with correctly sequenced house wrap and furring strips. Madison Pro Siding & Wrap installs exterior insulation using manufacturer-specified fastening patterns and furring strip spacing to maintain proper siding attachment over the added foam thickness.
Why Choose Us
Local Siding Contractors
We've installed and repaired siding on hundreds of homes across Madison County and Limestone County, giving our crews direct, repeated experience with the area's mix of 1990s-to-present suburban construction and older homes near the Madison Historic District.
Advanced Installation Techniques
Our crews are trained on manufacturer-specific fastening and flashing standards for James Hardie fiber cement products, along with proper house wrap lapping sequences that prevent water from tracking behind the barrier.
Proven Track Record
Our project history spans single-family ranch homes, two-story new construction, and historic properties requiring custom trim and matching work, giving us direct experience with nearly every siding condition found in the Huntsville metro.

Some of the Products We Proudly Use
Exterior Insulation Services We Provide
Rigid Foam Board Insulation Installation
Rigid foam board insulation, including XPS, EPS, and polyisocyanurate panels, installs directly over sheathing and house wrap to add a continuous thermal layer before siding goes up. Each foam type carries a different R-value per inch, and we select the product that best fits the project's thermal target and budget. Correct fastener length is critical since fasteners must reach through the added foam thickness into structural framing.
Furring Strip Installation for Rainscreen Assemblies
Furring strips create an air gap between the insulation layer and the siding, allowing any moisture that gets past the siding to drain and dry rather than sitting against the wall assembly. This rainscreen approach performs especially well in Madison's humid climate where trapped moisture accelerates rot. We install furring strips at the spacing required to support the specific siding type going over them.
Thermal Bridging Reduction Assessment
Standard wood-frame walls lose a significant share of their rated insulation performance through thermal bridging at studs, a problem cavity insulation alone can't solve. We assess existing wall assemblies during re-siding projects to determine where continuous insulation would deliver the most meaningful performance improvement. This assessment factors in the home's existing insulation levels and window-to-wall ratio.
Siding Attachment Over Continuous Insulation
Adding exterior insulation changes how siding attaches to the wall, since fasteners must span the added foam thickness to reach solid framing. We verify manufacturer-approved fastening schedules for each siding type installed over continuous insulation, since incorrect fastening is one of the most common causes of siding failure on insulated wall assemblies. This applies whether the siding is vinyl, fiber cement, or James Hardie product lines.
New Construction Continuous Insulation Compliance
Building codes in many jurisdictions now require a minimum continuous insulation value on new residential construction to meet updated energy performance targets. We install continuous insulation systems that meet current code requirements for new builds throughout Madison and Limestone County, coordinating directly with builders on inspection scheduling.
Types of Properties We Serve
New Single-Family Construction
Builders throughout Madison's newer subdivisions increasingly specify continuous insulation to meet updated energy code requirements and market new homes with lower projected utility costs. We install insulation systems sized to each project's specific thermal target during the framing-to-siding construction phase.
Full Re-Siding Residential Upgrades
Homeowners undergoing full siding tear-off throughout Madison and the surrounding Huntsville metro often add continuous insulation during the project, since it's the only practical time to install it without removing finished siding later. This is a common upgrade on older homes with minimal existing wall insulation.
Energy-Conscious Custom Homes
Homeowners building custom homes with specific energy performance goals frequently specify higher R-value continuous insulation than standard code minimums require. We work with architects and builders to install insulation systems matched to these higher performance targets.
What Our Customers are Saying
"We added continuous insulation during our re-siding project in Madison specifically because of our summer cooling bills. Noticeable difference the first season."
— Brian K., Madison, AL
"Our builder specified polyiso insulation on our new build in Harvest to hit the updated energy code requirements."
— Nicole T., Harvest, AL
"They explained the furring strip and rainscreen setup clearly before we committed to the upgrade."
— Ray D., Meridianville, AL
"Good experience overall, and they coordinated directly with our general contractor without us having to relay information back and forth."
— Carla V., Owens Cross Roads, AL
Exterior Insulation FAQs
How long does exterior insulation installation take on a typical Madison, AL home?
Continuous insulation installation adds roughly 1 to 3 days to a standard re-siding or new construction timeline, depending on wall area and furring strip requirements.
Do I need a permit for exterior insulation installation in Madison, AL?
Exterior insulation on new construction is reviewed as part of the overall building and energy code permit process, while re-siding upgrades on existing homes generally follow standard building code review.
Does exterior insulation come with a warranty?
Manufacturer warranties on rigid foam insulation products typically cover material defects for a set number of years, separate from installation workmanship coverage.
How much can continuous insulation lower my energy costs?
Homes with continuous exterior insulation commonly see measurable reductions in cooling costs by eliminating thermal bridging that cavity insulation alone can't address.
What's the difference between XPS, EPS, and polyisocyanurate insulation?
The three materials differ in R-value per inch, moisture resistance, and cost, and the right choice depends on the project's specific performance target and budget.
