Horizontal Sliders

Horizontal slider windows slides to the left or right for easy-to-open capabilities allowing in natural light and fresh air.

sliding window

Horizontal Slider windows open with the sash sliding left or right. Some people find sliding windows easier and faster to open than crank-style windows. Since they open and close without protruding, horizontal sliders are an excellent choice for rooms facing walkways, porches or patios. Horizontal sliders are a favorite for contemporary style homes and are also popular for satisfying bedroom egress requirements. In a single slider, one sash slides to open. In a double slider, both sashes open. Double sliders are great for providing air circulation, particularly if there is only one window in the room.

Horizontal Sliders is rated 4.4 out of 5 by 323.
Rated 5 out of 5 by from Added Value We had upgraded to Milgard Windows in 1996 because our windows were leaking and not very acoustically sound. When we sold our home in October of 2016 everyone that came through to view it commented on the beauty of the windows. Thanks Milgard for helping us sell our home!

Rated 4 out of 5 by from Good windows. Windows are nice. We also purchased a Tuscany series sliding patio door and are happy with it. The slider on the door for the between the glass blinds is installed crooked and we are looking into having it fixed properly. Also I do wish the installers would have cleaned the windows after they were done installing them. there are fingerprints and sticky stuff from the stickers and such all over them.

Rated 5 out of 5 by from Nice looking We are very pleased with the 8 replacement windows. Can't believe how much cooler the sunny side of the house became after installation. No more rattling, leaky windows!

Rated 4 out of 5 by from Imperfection There was an imperfection in one of the glass panes so the company has to come out and replace the pane.

Rated 5 out of 5 by from Retrofit - Couldn't be more pleased We recently remodeled our master bathroom. The original window was over 25 years old and wouldn't open. The salesman suggested the Tuscany Horizonal Slider. It fit perfectly without tearing our the old window frame or having to deal with repairing the stucco outrside. Very pleased with the product and ease of installation.

Rated 1 out of 5 by from Irresponsible 8/2/17 My Ultra glass doors are beautiful. I got a swing door with side lites, and a sliding glass door, both custom sized. They insulate well, both temperature and noise. I cannot recommend Milguard, however, because of multiple service failures. Due to manufacturing errors, neither door had functioning screens, with gaps ample for bugs to enter. This was reported by my installation company; then began my service saga with Milguard. There were months-long delays, a last-minute cancellation of an appointment for which I’d adjusted my vacation, and finally today’s long-awaited visit for which I’d adjusted my work calendar, only to have the crew arrive without a replacement needed to complete the repair. Installation was March 2, and it’s now August 2. During this time I’ve had the service department 1) fail to contact me for a couple of months, 2) when I instead contacted them via website service request (another long delay) and finally by phone, claim the installation company failed their reporting protocol, and 3) blame my installers for not fixing it (how were they supposed to fix a too-narrow screen, or one missing a part?) After Milguard’s own manufacturing errors, I would expect the company to take appropriate responsibility, not blame my installers, and to be more accommodating in scheduling a fix already long-delayed. I would expect that when the crew did arrive, they would have the replacement screen they knew I needed—after all, it’d been a month or so after their first, failed appointment (if they’d still needed it, you’d think they’d have manufactured it in the mean time). I would expect that they would have reasonable wait-times on the phone, and a supervisor who would wait for my last question this morning (rescheduling) instead of hanging up with a have-a-pleasant-day sign off, then claim he’d called me back twice during my hold when I called him back. (My phone, witnessed by the crew here, tells a different story. No calls.) The crew today was great, and I feel sorry for them having to deal with cranky customers like me due to this completely inadequate service system.
