At Acre Windows & Doors, every project is about improving how a home looks, performs, and feels year-round. This recent window and sliding glass door installation in Lancaster, PA showcases how strategic upgrades can completely transform a living space while improving energy efficiency.
The homeowner wanted more natural light, better insulation, and updated patio access — without compromising durability. Our team delivered by replacing an existing sliding glass door with two Andersen® 100 Series picture windows and upgrading a second patio door with a new Andersen® Perma-Shield® gliding patio door.
Project Overview (Before & After)
Replacing a Sliding Glass Door with Picture Windows
One of the most impactful changes in this Lancaster home was converting a sliding glass door into two large picture windows.
While sliding doors provide access, they also introduce framing that breaks up the view and can reduce energy efficiency over time. By installing Andersen® 100 Series picture windows in its place, we created a clean, expansive glass area that brings in significantly more natural light and provides unobstructed backyard views.
The Andersen® 100 Series is built with Fibrex® composite material, which offers long-term durability and strong thermal performance — ideal for Lancaster’s cold winters and warm, humid summers. These windows are low maintenance, resist warping and rotting, and provide a modern, streamlined appearance that complements a variety of home styles.
The result is a brighter interior space that feels more open and connected to the outdoors.
Upgrading to an Andersen® Perma-Shield® Sliding Glass Door
In another area of the home, we replaced an aging sliding patio door with a new Andersen® Perma-Shield® gliding patio door.
Older sliding doors often become difficult to operate and can allow drafts, especially in Pennsylvania’s fluctuating climate. The new Perma-Shield® door provides smooth operation, improved insulation, and enhanced weather resistance thanks to its vinyl-clad exterior and energy-efficient glass options.
This upgrade restored easy access to the backyard while improving overall comfort inside the home. The slimmer design and updated finish also modernized the rear exterior of the property.
