LW Series In-Glass Pet Doors
If you have pets at home, you’re probably all too familiar with the constant routine of opening and closing the door. It’s a small task that adds up, especially for owners of active dogs or independent cats. The LW Series Pet Door offers a better solution. Built directly into the glass of our LW Series patio doors, this integrated pet access system allows your animals to go outside whenever they want — without interrupting your day or sacrificing your patio door’s look, function, or energy efficiency.

Innovative Features You and Your Pet Will Love
The LW Series Pet Door is more than just a convenient upgrade—it’s a thoughtfully engineered feature designed for real homes and real pets. Built from durable materials and placed directly into the glass panel of your patio door, it offers long-lasting performance and seamless integration. With four available sizes, flexible placement options, and secure, energy-efficient sealing, this pet door delivers everyday convenience without compromising the look, function, or comfort of your home.
Durable Materials and Perfect Placement
LW Series Pet Doors are built with durability in mind. The frame is made from high-strength aluminum and is built to withstand daily use, even by large or energetic pets. The flap is flexible yet sturdy, held in place by embedded magnets that ensure it stays closed after each pass-through. A dense weatherstrip adds insulation around the pet door flap and helps keep out wind, rain, and debris.
Each pet door is installed in the lower corner of a fixed or operable glass panel, allowing you to choose the most convenient location for your layout.
Secure and Energy Efficient
The LW Series Pet Door includes a rigid closure panel that can be inserted and latched. It is ideal for keeping pets inside or outside, depending on who is home, the weather, and the time of day. This panel adds a layer of security and insulation when the pet door isn’t in use.
Built-in magnets and weatherstripping around the flap help seal the flap opening to reduce drafts and maintain indoor temperature. Whether it’s a hot summer day or a cold winter night, your home remains energy efficient and secure from the elements while still giving your pets the freedom to come and go. It’s a simple way to manage access without leaving the door unlocked, so you never have to trade security for convenience.
Size and Placement for the Perfect Fit
Every pet — and every home — is different. That’s why the LW Series Pet Door is available in four sizes, allowing you to match your door to your pet’s size, breed, and comfort level. Whether you require a small indoor cat door or a large, active doggie door, there’s an option that provides safe, easy access without creating an oversized opening.
With the right size and strategic placement, your pet will enjoy comfortable access, and you’ll enjoy a solution that blends perfectly into your patio door.
A Closer Look at LW Series Patio Doors
While the built-in pet door is a standout feature, the LW Series patio door is just as impressive. Available in sliding and French swing styles, these doors are engineered to perform in the Northwest’s varied climate while enhancing your home’s beauty, comfort, and efficiency.
Sliding glass doors are ideal for maximizing floor space and easily connecting indoor and outdoor areas. French patio doors bring a more traditional aesthetic and dramatic presence to formal living rooms, garden entries, and dining spaces. Both styles share the same core construction and performance features, ensuring reliable operation and long-term value regardless of your chosen configuration.
Key Features and Benefits:
- Effortless operation: QuadraGlide™ rollers and precision bearings create smooth, quiet sliding motion over a heavy-duty stainless steel sliding door track.
- Enhanced security: Optional multi-point locking systems offer increased protection with up to four secure contact points, so you no longer need a security bar to keep your doors secure.
- Superior insulation: Comfort•Core™ foam and Inner•Core™ fiberglass reinforcement boost energy efficiency and structural strength.
- Weather resistance: Triple-Guard weatherstripping seals out moisture, drafts, and noise while resisting bacterial buildup.
- Noise control: The LW Sound Package includes dual-pane dissimilar glass to minimize street and traffic noise.
- Durable screen system: Heavy-duty aluminum screens with self-latching handles offer lasting performance and easy use.
- Expansive views: Narrow frame profiles and large glass areas let in more natural light and improve outdoor visibility.
- Custom configurations: Choose from two-, three-, or four-panel layouts, with transoms, sidelights, or swing panel options available.

FAQs – LW Series In-Glass Pet Doors
Can I add an LW Series Pet Door to an existing patio door?
No. LW Series Pet Doors are built directly into the glass during manufacturing and must be included when the patio door is ordered. They are not an add-on or retrofit option.
How do I know which pet door size is right for my pet?
Choose a size based on your pet’s weight and shoulder height. Our size chart will provide a reference based on shoulder height and common breeds.
Is the closure panel easy to use?
Yes. The panel slides into the pet door frame and latches securely. Inserting or removing as needed for cold weather protection or security is simple.
Can I lock the pet door?
The closure panel acts as a lockable barrier. The pet door is fully sealed and cannot be accessed outside when inserted and latched.
Will the pet door reduce the functionality of the main door?
Not at all. The LW Series Pet Door is slim enough that the main sliding or swinging door still operates normally, even with the closure panel in place.
What happens if the glass panel with the pet door breaks?
The glass used in LW Series patio doors is engineered for strength and durability, and it’s extremely rare for it to break under normal conditions. However, in the unlikely event that it does, your door is protected by our True Double Lifetime Warranty, which covers both the glass and the integrated pet door for as long as you own your home — and it’s fully transferable to one additional homeowner.
Do you offer LW Series windows to match these doors?
Yes! LW Series windows are designed with the same energy-efficient performance and sleek design as our patio doors.
