We Make Homes Happier
Most window stores sell units in boxes. We don't. At Eisenhardt Studio, we upgrade how your home feels—warmer in winter, cooler in summer, quieter from traffic, and filled with natural daylight that transforms ordinary rooms into extraordinary spaces.
We design, deliver, install, and service. We're accountable for the whole experience, from the first consultation to decades of ongoing support. This isn't about moving product—it's about creating environments where families thrive.
When street noise fades to silence, when winter drafts disappear, when summer heat stays outside where it belongs—that's when a house becomes truly happy. That's when you feel the difference between ordinary windows and the Eisenhardt approach.
We don't just sell windows. We deliver comfort.
From Renovation… to Custom Homes… to Eisenhardt Studio
The Beginning: Renovation Experts
We started as a renovation company in the Philadelphia area, earning trust through difficult remodels that demanded precision and problem-solving.
Evolution: Custom Home Builders
Our reputation grew, leading us to build high-end custom residences for discerning Main Line clients.
The Problem: Underperforming Openings
We repeatedly encountered the same issue—off-the-shelf American windows and doors underperformed with ugly frames, drafts, noise, and poor security.
The Solution: European Systems
To solve this, we began sourcing advanced European window and door systems for our own projects. Our clients instantly felt the difference—quieter, more comfortable, and dramatically more beautiful.
The Focus: Eisenhardt Studio Today
That transformation became our obsession and our specialty. Now, we bring that same European excellence and comfort to every project we undertake.
"We didn't pivot into windows. Windows pulled us in."

Tilt-and-Turn Windows: Quiet, Secure, Beautiful
The European Standard That Transforms Main Line Homes
Tilt-and-turn windows represent a fundamentally different approach to residential fenestration. Where American double-hung windows offer limited functionality and compromised performance, European tilt-and-turn systems deliver precision engineering that you can feel the moment you operate the handle.
These aren't just windows—they're sophisticated climate control and security instruments that happen to be beautiful.
Why Main Line Homeowners Choose Tilt-and-Turn
  • Slim European frames mean more glass area, more natural daylight, and cleaner sightlines that showcase your views without bulky obstructions
  • Multiple opening modes provide ventilation without drafts—tilt for secure airflow or turn for full access and cleaning from inside
  • Triple glazing with thermal insulation creates an invisible barrier against temperature extremes and dramatically reduces energy costs
  • Acoustic control blocks street noise, neighbor sounds, and traffic din for peaceful, quiet interiors
  • High-security hardware with multi-point locking provides bank-vault protection when you're home or away

Recommended Application
Ideal for Main Line street-facing rooms, bedrooms requiring quiet and security, and any space where you want superior thermal comfort with elegant aesthetics.
Massive Sliding Glass Walls
This Is How You Turn a House Into a Showcase
Lift-and-slide glass wall systems erase the boundary between interior comfort and outdoor beauty. These are the openings that make architects smile and homeowners stop mid-sentence to simply stare at the view.
Floor-to-ceiling glass panels—some spanning 10, 12, even 16 feet wide—glide open with a gentle push despite weighing hundreds of pounds. The secret? German-engineered hardware systems that elevate panels off their track, then glide them horizontally on precision bearings before gently setting them back down.
This isn't the jerky, binding operation of typical patio doors. This is mechanical poetry.
Built for Main Line Living
  • Seamless flow for kitchens, family rooms, and poolside entertaining
  • Daily-use reliability engineered for years of smooth operation
  • Thermal break frames maintain comfort through all seasons
  • Weather seals that actually work—no drafts, no leaks
