Replacement siding adds beauty to your exterior and acts as a protective barrier against heat loss or gain. It helps keep undesirable drafts out of your interior and decreases your energy use—which lowers utility bills.
Siding forms the exterior envelope of your house, delivering the initial line of defense against the elements, including moisture intrusion, high winds, heavy rain, snow, extreme temperatures, and more. Read on to learn more about how siding is a key factor in home insulation, and how it contributes to energy savings.
Enjoy Greater Indoor Comfort and Lower Utilities with New Siding
Siding establishes a boundary that aids in regulating your home interior’s climate, keeping air conditioning inside each summer and heated air indoors each winter. It has a host of advantages:
Use Less Energy
Your energy consumption will go down when you replace your siding with quality material.
Save on Utilities
By using less energy to heat and cool your house, you will save consistently on monthly utility costs.
Preserve Your HVAC Unit
When your home is well protected with siding, your heating and cooling system won’t have to work as hard to maintain the desired temperature. This will help preserve your siding’s lifespan, and you won’t need to repair or replace it as soon.
Enjoy Greater Indoor Comfort
When your house is well insulated with new siding, your interior will be more comfortable throughout the year. The temperatures from room to room should no longer vary, and you’ll enjoy consistency throughout. For even greater interior comfort, address any gaps in your windows.
Preserve Your Home’s Structure
New siding can contribute to your home’s longevity. Why? Because it keeps moisture intrusion at bay, so you avoid the cost and hassles of mold, mildew, and wood rot. This positively contributes to your house’s structural health by keeping it dry.
Contribute to Environmental Sustainability
By lowering energy consumption and greenhouse gas emissions associated with heating and cooling your home, you decrease your carbon footprint.
How the Siding Material You Choose Impacts Your Home’s Insulation
The makeup of the siding material you select for your exterior upgrade will directly impact its insulating capacity.
Vinyl
This affordable material is often chosen for its low maintenance and exceptional insulating capabilities. It can be installed as traditional vinyl siding or insulated vinyl siding—which is highly prized for its extra layer of foam insulation that acts as a thermal barrier, keeping heat from escaping your home interior by minimizing heat transfer. It basically creates a blanket to help your interior maintain a consistent temperature. Insulated vinyl siding has a higher R-Value than traditional vinyl, ensuring your home is well protected from extreme outdoor temperatures.
Fiber Cement
Fiber cement is made of cement, sand, and cellulose. And James Hardie—the leader in the fiber cement industry—delivers durable siding that is moisture resistant, pest resistant, and fire resistant. Its resistance to temperature-induced expansion and contraction makes it a top choice.
The resilient makeup of Hardie siding and trim ensures your home’s protective layer stays intact, and unpenetrated by whatever nature throws at it. Its longevity (up to 50 years when installed properly and maintained well) means your home will be safeguarded from its enemies—water and pests—and will reliably shield your house from the elements.
Stone Veneer
This beautiful siding material is sought out due to its aesthetic appeal. It’s cost effective and adds sophistication to your exterior. Stone veneer has what’s called “thermal mass,” meaning it absorbs heat during the day and slowly releases it at night, which helps moderate indoor comfort by minimizing extreme temperature fluctuations. To optimize energy efficiency, consider installing insulation behind your stone veneer to block heat transfer through the wall and into your home.
