Sliding windows: Quick facts

Sliding windows or gliders are installed horizontally, with sashes that slide along the track from left to right or vice versa. This window style is one of the most popular choices for many Canadian homeowners. They are so demanded since:

  • Sliders proved terrific, unobstructed view outside
  • Provide great energy-efficiency
  • Easy to operate
  • Allow exceptional ventilation and bring much natural light to your area

Window frames: What you can choose from?

There are many frame materials to choose from. The main and most popular ones include wood, vinyl, aluminum, and fiberglass. Each type has its own pros and cons to consider. So, let’s get right into and figure out all the features of each frame type.

Wood: Traditional and great looking

If you’re after elegance and a classic look, then wood is your go-to option. It is a common choice among Canadian homeowners for many reasons.


  • Super durability
  • Amazing look
  • Traditional, all times classic

Low condensation and great sound cancelling


  • The most expensive material
  • Needs frequent maintenance
  • Vulnerable to insects

Aluminum: Light but durable

For many Canadian homes, aluminum windows are a good pick. They look great, requiring less maintenance than wood. Aluminum is also lightweight but very durable and can hold large areas of glass.


  • Cheaper than wood
  • Less maintenance
  • No damage from insects
  • Easier to install


  • Low energy-efficiency
  • Increased moisture
  • Does not fit every design

Vinyl:  Your best option

Vinyl window frames are made of PVC (polyvinyl chloride). This material is probably the middle ground for many homeowners.


  • Much cheaper compared to other materials
  • Can fit any design
  • Does not require frequent maintenance
  • Exceptional energy-efficiency


  • Difficult to recycle
  • Might fade over the years

Okay, you read till this point, and now you know a lot about window frames and what fits you best. But here comes another vital aspect to keep in mind. Installation. Even the best windows will not serve you long if the installation is poor. Ecoline Windows experts recommend to check whether you installers:

  • Follow CSA guidelines as well as your local building codes;
  • Have years of experience and perfect reputation;
  • Offer only Energy Star-rated and NAFS-11 tested windows;
  • Provide you a decent warranty and post-installation support in case issues arise.
