Types of Sliding Windows

Both single and double sliding windows have two sashes. In the former, only one is operable and the other is fixed in its place. Both sashes can open simultaneously or alternatingly in the latter, letting in more air than its single counterpart. 

Both of these sliding window types are similar in terms of operability. Their movable sashes slide horizontally along a set track on the window frame. These sashes can be removable, making it easier for you to clean them. 

Structurally, the two types of sliding windows are rectangular and have a landscape orientation. They become hung windows when manufactured vertically. 

4 Differences of Sliding Window Types

Let’s compare single and double sliding windows and see how they compare in four crucial aspects: cost, ventilation, size, and energy efficiency:

Cost

The standard price of the two types of sliding windows ranges from $250 to $1,800, installation fee not included. However, double sliding windows are generally more expensive since they require more material and mechanical parts for assembly. If you consider adding insulation, glazing, frame designs, and size, it’s only natural that the costs increase.

Ventilation

A single slider window offers limited air circulation since its maximum opening area is equal to a single pane. Double slider windows offer more fresh air since you can open both sashes at once, allowing air to enter at two endpoints. 

Some window manufacturers have moved away from traditional sliding windows by producing models that open like a casement window to achieve maximum ventilation at home.

Size

If you’re going for small-scale or something that fits tighter spaces, single sliding windows are great since they have smaller size options than double sliding windows. The latter is usually available in bigger sizes to display expansive views and let natural light come in.

Energy Efficiency

The two sliding window types are not as energy efficient as casement, awning, and fixed windows. They have more moving parts that give air a chance to leak out. But if you compare them both, single sliding windows offer better energy efficiency since they only have one movable panel that can cause air leaks. 

Sliding windows can have improved energy efficiency when you choose the right materials, glass glazing, and number of panes. For instance, Burano Doors’ windows with low-E glass reflect UV rays back into your home while keeping the cold outside at bay. Consulting with our window specialists and energy advisors can help you determine the best customization route that’ll keep you comfortable in all seasons.

Benefits of Sliding Windows

Let’s discuss what makes the two types of sliding windows stand out more than other window types:

Easy Operability

Single sliding windows are easy to operate since all you have to do is unlock its latch and open the window by pushing its panels to the side. The same thing applies when you close the window.

Low Maintenance

If you’re busy all days of the week, sliding windows are perfect for you since they’re low maintenance. You can clean them once a month to remove dried dust and debris on their surface. As for its mechanical parts, you’ll only need to spray lubricant on its track to ensure it slides smoothly. 

Unobstructed View

Enjoy expansive views of the outdoors when you install single or double sliding windows in your home. Unlike single and double-hung windows, their glass surfaces don’t have any obstructions to ruin your view.

Guaranteed Safety in High Traffic Areas

Casement and awning windows become hazards since their panels extend outward when opened. Sliding windows are different since their panels stay within the window opening, making them the best choice for indoor and outdoor spaces.

Style Versatility

Sliding windows are highly customizable, and you have a wide selection of styling options to make them personalized. Most window manufacturers offer various window materials, colours, trim designs, and other embellishments. 

Customizable Security

Sliding windows come with a built-in multi-locking point system that prevents outdoor tampering; only you can control the locks from inside your home. Besides that, Canadian homeowners can also add window films, frosted glass, grilles, and screens to increase their overall home window security.
