Replacement siding, improving energy efficiency, Craftsman Exterior Remodeling

As energy costs rise, upgrading your exterior is more important than ever. Siding replacement is a great place to start when looking for ways to lower energy use. It will improve your home’s insulation, reduce drafts, decrease heating and cooling costs, and preserve your HVAC unit. 

Read on to discover a variety of ways replacement siding can increase your house’s energy efficiency and save you money.

4 Ways New Siding Boosts Energy Savings 

The fundamental reason for new siding is to prevent extreme outdoor temperatures and moisture from infiltrating your home. The result? Greater indoor comfort and energy efficiency (and lower utilities!). And a not-so-obvious byproduct of siding replacement is that less outdoor noise will penetrate your home, making its atmosphere even more relaxing. Replacement siding increases energy efficiency by: 

1. Increasing Insulation

When you upgrade your exterior with replacement siding, your current siding is removed. This exposes any hidden areas that may be suffering the effects of water infiltration. Rot, mold, and deterioration may all be found under your current siding. Your contractor will repair the damaged area, fortifying your home’s protection. You may also have insulation added to your home for better thermal resistance. Increased insulation typically improves energy efficiency, lowering utility bills. Next, your house will be wrapped with a breathable insulation layer that won’t trap moisture in, but will allow your home to breathe. 

2. Reducing Drafts

When your siding is replaced, flashing will be added around doors and windows to prevent uncomfortable drafts. Flashing will help eliminate extreme temperature fluctuations and chilly winter drafts from penetrating your interior. 

As a bonus, realize that anywhere you’re keeping outdoor temperatures from infiltrating, you are also keeping water from penetrating your home. (And water can cause costly damage!) 

3. Lowering Heating and Cooling Costs

Quality siding material installed with precision and maintained well will offer weather resistance and pest resistance, keeping your home well sealed from the elements and therefore increasing energy savings. When your exterior is covered with siding material designed to withstand the Indy weather (like Hardie siding), you can expect to see greater energy efficiency. You’ll also enjoy the fact that it requires almost no maintenance and stands up to high winds and extreme temperatures. 

4. Preserving Your HVAC Unit

When you have energy-efficient siding installed on your home exterior, your home will maintain a comfortable temperature with ease. This translates into the preservation of your heating and air conditioning unit. Repairs on HVACs are not cheap, and it’s a sizable investment to purchase a new unit, so the longer you can keep using your current heating and cooling system, the better. 

Popular Replacement Siding Materials to Optimize Energy Efficiency

Weather-Resistant James Hardie Siding

Made of cement, sand, and cellulose, thick Hardie siding will seal your home against outdoor temperatures and contribute positively to lower energy usage in your home. It lasts up to 50 years when installed with precision and maintained well over the years. It’s engineered to stand up to extreme weather, and won’t let outdoor temperatures or moisture seep into your home. At Craftsman Exteriors, we are an Elite Tier Contractor within the James Hardie ALLIANCE, so we install this outstanding siding according to the manufacturer’s standards, ensuring optimal performance and enduring results. 

Premium Vinyl Siding 

At Craftsman Exteriors, we install Crane Performance Siding’s insulated or uninsulated vinyl siding. You’ll love how insulated vinyl siding boosts your home’s energy performance and positively impacts your utility bills. Its built-in insulation layer yields a high R-value (R-value is the ability to resist heat flow and measures how well a material insulates), improving thermal performance and making your home more comfortable. This siding was made with moisture management ridges that help keep water from accumulating behind it. 

We also install industry-leading Mastic® Vinyl Siding. This gorgeous siding comes in hundreds of colors and styles. We’re a Mastic Preferred Installer, so we ensure your siding is installed to perfection so it will deliver the high performance it was designed to give.
