Folding Glass Combination Systems

If you’d like both a sliding window and door system, our Frameless Glass Door Systems connect to a smaller window version of our system without a supporting wall or post. This combination is traditionally used in open kitchen transformations, but many clients opt for a variety of other applications.

Counter Height Systems

Our Counter Height Glass System is a great feature to have, not only as an operable window, but additionally, as a pass-through opening when entertaining outdoors. A Counter Height System creates a seamless pass through that maximizes countertop space, while allowing continued conversation from the inside to the outside.

Top Hung System

We take all the weight from the underside of the header by design. Our bottom track is purely just a wheel guide. Being a top hung system you cannot lift or pry out a panel which is a very important security aspect and overtime, the weight of the glass panels will not put the lower wheels under duress causing the system the become tough to slide, which is what can occur when using a bottom hung system.

Continuous Glass Doors

Experience a new level of clarity, as Cover Glass USA’s folding glass doors have no vertical frames between the glass panels. Instead, they interlock directly into each adjacent panel with a UV protected translucent polycarbonate channel that tightly seals, ensuring you’re still protected against the elements and leaving your space free of bulky obstructions.

Six design options for flexible track design.

Flexible Track Design

When it comes to design, nothing is standard with Cover Glass USA. We specialize in creating unique openings for our clients and can work with a variety of angles. As long as we have the appropriate channel to seal the corner, consider your project done. We can build a custom frameless glass door that is perfect for your project.

Multiple Combinations

Because each folding glass door panel slides individually, Cover Glass USA’s Frameless Sliding Glass Door Systems offer the unique ability to open your system however you see fit. Open one to use as a door, open a few or thoroughly when entertaining, or create air gaps to get some fresh air. The options are endless, and the choice is all yours.

Internal Locking Hardware

For an effective yet concealed look, our deadbolt locks both at the top and the bottom of the first panel to the inside of our glazing channel. This allows for the seamless look of our system to stay uninterrupted, while still ensuring your safety. Alternatively, if you prefer "essential entry access" from the outside or a lock for every panel, we do have an option for both.

Magnetic Stacking Panels

To protect our clients and their loved ones, we’ve equipped each of our frameless glass doors with high strength magnets, so as soon as you open and stack the panels, they magnetize together. This prevents the panels from flailing around if a strong gust of wind comes, or if anyone a bit clumsy happens to walk into them.

Customization for your Door System

We custom design every Frameless Glass Wall System exactly to your needs, and offer a variety of options to choose from.

When it comes to design, nothing is standard with Cover Glass USA. We specialize in creating unique, custom systems for our clients, and can work with a variety of angles. There are thus a wide variety of systems we can configure depending upon your project's needs. Systems can be made to open and stack to either the interior or exterior, and slide to the left or right.

Each sliding glass panel is 1/2″ or 3/8″ thick and consists of two industrial laminated pieces of tempered glass. We use the latest generation of Pilkington's Energy Advantage Series. Number and width of the glass panels are chosen in relation to the length of the system.

Each sliding glass panel is generally between 24″ to 33″ in width and up to 110″ (9’2″) in height. Other sizes of width are available, but please note 110″ is our height restriction. In order to find the best panel width for each system, we typically take the width of the proposed area and divide it into equal-sized panels. We generally recommend staying in between 22″ – 33″, due to the increased weight of the door as the panels increase in size. Depending on each job’s needs, we have the ability to create a panel at a minimum of 18″ wide and as wide as 34″.

The maximum height of our sliding glass panels can be up to 9′ 2″; there is no minimum height per se, but we suggest a minimum of 2′ 6″ H. Our height is limited to 9′ 2″ because without the added structure of a frame at above that height, sometimes the glass will have a tendency to bow. As we want to ensure our systems always operate smoothly, we choose to stay safe rather than sorry. Similarly, we recommend a minimum height of about 2′ 6″ tall, so our internal operating systems remain fully functional.

Cover Glass locking mechanism
Different angles of the glass door locking mechanismOur standard locking mechanisms are two deadbolts that lock both at the top and bottom of the first opening panel. This provides both an effective lock and allows for the seamless look of our system to stay uninterrupted. With no floating handles to disrupt the frameless glass feel, the result provides exceptionally clear views. Alternatively, if you prefer a handle with key entry access from the outside or a lock for every panel, we do have both of those options available.

Depending on your property’s exposure, you may want to use glass that has an additional tint* on it, to assist with the level of protection from the rays of the sun. Our standard color is clear, but we also carry a light gray, light bronze, light blue glass, green glass, and a reflective bronze. We have samples of each color available at all our showroom locations for you to determine which color is right for your project.
