Sliding Windows

Sliding windows (also called slider windows) slide to open, either vertically or horizontally. Single hung sliding windows have one pane that slides. In double hung models, both panes slide.

Long Life slider window systems feature exceptional, easy to use, sliding vinyl replacement windows. Their quality construction, multi-chamber design, and triple weather stripping offer outstanding performance and energy efficiency.

Our sliding windows come standard with a pivoting sash – so you can clean the outside of the vinyl windows from the inside.


  • We understand that customers want their windows to last. The unparalleled quality of Long Life sliding windows gives high value in an affordable package.
  • Our windows are Energy Star® certified for zones A, B, and C.
  • Each of our slider windows has energy efficient, highly air tight, triple weather stripping to reduce drafts as well as heating and air-conditioning costs.
  • These windows are tough. They are strong enough to withstand winds of over 300 km/hr, and the efforts of a determined intruder.
  • The classic design of our sliding windows coordinates with both traditional and contemporary homes.
  • The multi-chambered construction gives each window extra rigidity and added energy efficiency.
  • The slider track is wide and easy to clean. The window sash glides on nylon glides, so there are no brass or plastic wheels to wear out or leave unsightly tracks.
  • All our vinyl replacement windows are locally manufactured, made for our wind-driven rainy weather, and backed by people with a long-term reputation for reliability.



Our wide variety of dimensions and configurations allow you to customize your windows for the look and function you want. Ask your Long Life representative for images or illustrations of the available options. Remember that you can choose vertical or horizontal sliding windows, and that that both sashes slide in a double hung window.


Different types of glass have distinct qualities and attributes. Selecting the best glass for each window can minimize noise issues, winter heat loss, or fading.

The following five questions can help determine the best glass for each of your windows:

1. Is your home cold in the winter?

Windows are the main sites of heat loss in most Canadian homes. Installing replacement windows will reduce drafts, but even well-sealed windows lose a significant amount of heat. Selecting glass with a high performance, energy efficient glazing can reduce your home’s heat loss, and bring down your heating bills at the same time.

2. Is your home too warm in the summer?

Excess heat gain in summer can cause as much discomfort as wintertime heat loss. Well-sealed replacement windows will reduce some heat gain, but the key culprit is heat coming through the glass. To minimize heat gain, select glazing that eliminates infrared light. Fortunately, the same glazing will also reduce winter heat loss.

3. Is fading a problem in some rooms?

Strong, direct sunlight can fade furniture, paintings and flooring. Where this is an issue, choose glass that screens out ultraviolet radiation (UV rays) to protect your furnishings from damage and deterioration.

4. Do you live on a busy street, or is it noisy inside your home?

In addition to light, windows can also let in unwanted noise.  Most sound is made up of acoustic vibrations at different frequencies. Laminated glass minimizes unwanted sound transmission because the plastic inter-layer dampens vibrations across a wide range of frequencies, quieting low frequency sounds like truck traffic, as well as high frequency noise, like jet aircraft or industrial equipment.

5. Is security an issue?

Safety concerns can be easily addressed by selecting tempered glass or laminated safely glass. We usually recommend using laminated safety glass as it also helps reduce noise transmission and blocks 99.8% of the UV rays that cause fading.

The Building Code requires the use of safety glass anywhere within three feet of an entry doorknob and in a bathtub enclosure. We also recommend it for  basements, garages or any window that could be an easy entry point.


We offer a variety of glass types to suit the needs of each room in your home.

LoE3 Glass with Argon
LoE3 (pronounced: low E cubed) addresses all three of the biggest residential window concerns. LoE3 reduces winter heat loss, summer heat gain, and blocks 95% of the UV rays that cause fading and deterioration.

Laminated Glass
Laminated glass provides increased safety and security, reduces unwanted outside noise, and blocks 98% of the sun’s UV rays.

Neat Glass
Neat glass uses the sun’s UV rays to help loosen dirt so water can rinse it away, leaving your windows virtually spotless. This low maintenance, easy to clean glass is ideal for hard to reach places. Read more about Neat glass.

Obscure Bathroom Glass
We offer a broad selection of obscure glass options for bathroom privacy.



Our high efficiency vinyl windows come standard in white or beige, but if colour is what your home needs to look its best, simply select frame and trim colours from our popular palettes – or we can custom match a sample of your own colour choice. (Note: colours as shown are approximate. Ask your Long Life representative for colour samples).framecolors


Add a heritage feel to your windows with Long Life Simulated True Divided Lite (STDL) or Standard Internal Muntin grids.

STDL grid bars are permanently attached to the outside and inside of the glass to create the look and feel of a wooden grid. The bars can be colour matched to your frame, and come in three width options.

Internal Grids or Muntin Grids, are permanently fixed inside the sealed unit and come in a variety of colours, shapes and patterns. Because they are attached in between the glass panels they are a low maintenance alternative to STDL bars.

We offer a full range of standard window grid patterns, or we can create customized grid patterns on request.

Interior and Exterior Trims:

Long Life offers a number of interior and exterior finishing touches to customize your new windows, including: exterior brickmoulds and rebate flanges from 1″ to 2″, or a 2 1/2″ stucco moulding. Alternatively Long Life can trim your windows with wood. We also offer an authentic looking wood grain stain.

We don’t normally disturb the interior jamb of the window. However, you can choose to have new sills and casings installed. Be sure to ask us about all the options.

Window and Door Hardware:

We offer a variety of colours, finishes, and locking features. Ask us about the hardware options for your window types.
