Proven Energy Savings
Where Patio Door Inserts Make the Biggest Difference
Condos Facing Traffic or Construction
Large balcony doors can expose living rooms and bedrooms to road, rail, construction and neighbourhood noise. An interior insert adds sound control without changing the building exterior.
Cold or Drafty Rooms
Sliding glass doors can make nearby rooms uncomfortable during Canadian winters. Adding an interior glazing layer limits heat transfer and creates a warmer interior barrier.
Homes Where the Existing Door Still Works
If the patio door frame and operating system are still in usable condition, replacing the entire unit may be unnecessary. An insert targets acoustic and thermal performance while allowing the original door to remain.
Commercial and Multi-Residential Properties
Interior installation can improve comfort in offices, apartments and other buildings without major exterior construction.
Large or Custom Patio Door Openings
Each Magnetite system is individually measured, making it suitable for oversized and non-standard configurations that cannot be addressed with off-the-shelf inserts.
ProCore Sliding Door System
Effortless Comfort & Access For Patio Doors
Magnetite® ProCore patio door inserts are designed specifically for sliding patio doors, improving insulation and sound control while maintaining smooth, everyday door operation. These patio door window inserts install on the interior and enhance comfort without replacing your existing door.
A smooth-glide PVC guide channel allows the insert to open and close easily, while a vertical handle strip supports effortless use. ProCore delivers a quieter, more comfortable space while preserving full door functionality.
Quick, Clean & Custom-Fit Installation
Each ProCore system is custom-measured and professionally installed for a clean, built-in finish. As specialized inserts for sliding doors, installation is completed from the interior with no exterior modifications and no construction mess.

A Magnetite insert is particularly useful when the existing patio door still functions but noise, drafts or temperature transfer remain a problem.

Our Customers Frequently Asked Us
FAQs
What are patio door inserts?
Patio door inserts are custom interior panels designed to fit over existing sliding or patio doors. They create an added insulating layer that improves comfort, reduces noise, and enhances energy efficiency without replacing the original door.
How do patio door window inserts help reduce noise?
Patio door window inserts reduce noise by adding an additional barrier and increasing the air space between the insert and the existing glass. This design helps block outside sound and is especially effective for patios facing busy streets or shared outdoor spaces.
Are patio door inserts available for sliding doors?
Yes. Patio door inserts are commonly used on sliding doors and function similarly to sliding window inserts. They are custom made to ensure a tight fit that minimizes drafts, vibration, and sound transfer.
What materials are patio door inserts made from?
Our patio door inserts are available in acrylic. Sometimes referred to as plexiglass door inserts, acrylic inserts are lightweight and impact resistant.
Can patio door inserts improve energy efficiency?
Yes. By sealing air gaps and adding an extra insulating layer, patio door inserts help reduce heat loss in winter and heat gain in summer. This can lead to more stable indoor temperatures and lower energy costs.
Will patio door inserts affect how my door operates?
Patio door inserts are designed to work alongside your existing door system. They install on the interior side and do not interfere with normal door operation when properly measured and installed.
Are specialized inserts available for large or unique patio doors?
Yes. Specialized inserts are available for oversized doors, multi panel patio doors, and unique configurations. Each insert is custom measured to ensure proper fit, performance, and ease of use.
Are patio door inserts removable?
Yes. Patio door inserts are fully removable, making them easy to clean or remove seasonally if needed. This provides flexibility for homeowners who want a non permanent upgrade.
