Custom Storm Windows for Historic Homes – Beauty Meets Efficiency
Let’s face it—your original single-pane windows weren’t designed to fend off 21st-century utility bills. But before you rip them out for vinyl double-hungs (please don’t), there’s a better way: storm windows. In this blog, we’ll explore how custom interior and exterior storms give you the efficiency of modern windows without compromising your home’s historic charm.
What Are Storm Windows?
Storm windows are secondary glazing panels installed either on the inside or outside of your existing window sash. They act like a thermal barrier, reducing drafts, blocking UV rays, and enhancing insulation without touching the original window.
Two types:
Exterior storms: Mounted outside, typically aluminum-framed. Visible but weatherproof.
Interior storms: Mounted inside, often magnetic or compression fit. Virtually invisible.
Why They’re Perfect for Historic Homes
Preserve Original Windows: No removal or alteration needed
Boost Efficiency: Up to 50% reduction in heat loss
Reduce Noise: Great for city homes or busy streets
Protect Historic Glass: Acts as a buffer from wind, hail, or lawnmower rocks
Custom vs. Off-the-Shelf
At Austin Historical, we don’t recommend box store storms—they rarely fit historic windows properly. Instead, we design custom storms with the correct sightlines, shape, and low-profile frames.
Options include:
Low-E glass
Tempered for security
Removable panels for ventilation
Wood-framed storms for visual match
Installation Tips
Ensure a tight seal, but don’t trap moisture
Ventilation holes can prevent condensation
Match frame colors to sash or trim
Use hangers that allow for seasonal removal (especially for wood storms)
Common Myths Debunked
"They make windows look clunky." → Not if designed well.
"They don’t help much." → Studies show storm + original = near modern performance.
"They damage trim." → Not true when properly installed.
Bonus Benefits
Hurricane Protection (when paired with laminated glass)
Historic Tax Credit Eligibility (preservation-friendly solution)
Lower Insurance Premiums in wind zones
Final Word
Think of storm windows as a tailored suit for your historic sashes. They protect, insulate, and elevate—without erasing your home’s soul. If you want comfort and character, custom storms might just be your perfect match.
