get a quoteAre your windows and doors falling short in adding beauty and functionality to your home? Poorly designed or outdated windows and doors can make it difficult to maintain a consistent temperature, increase energy costs, and impact your home’s overall comfort and performance. If they’re aging, cracked, hard to open or close, or don't match the overall aesthetic of your home, they can make your space feel less inviting and take away from the effort you've put into your interior and exterior design. At DeCola Windows & Doors, we offer a comprehensive solution with high-quality windows and doors that are functional, stylish, and designed to complement any home design.
Contemporary style with an increased amount of light and larger view. Casement windows have become more common in more recent buildings, beginning in the late 1980s. Casement windows swing open in the same fashion a door would, hinged at the frame and swinging outwards. Casement windows offer a better air seal than the more traditional double hung windows because the lock mechanism pulls the window sash tight into the weather seal, compressing it to create a tighter seal, while hung windows do not have this ability. Our casement windows operate with a turn crank and feature multi-point locking mechanisms.

Awning windows are similar to casement windows in that they are hinged and open outward. The major difference between awning and casement windows is that awning windows are hinged at the top of the frame rather than on the side of the frame. Awning windows are also typically used above or below a window, or above doors. Awning windows are usually wider than they are tall, but can be customized to virtually any size.

Hung windows give your home a more traditional appearance. Single hung windows are a very simple window, made of an upper and lower panel. The upper panel is fixed while the lower panel slides up and down to allow for ventilation. Since there is only one operating panel, there is a screen only on the operating half of the window.
Double hung windows have two operating sashes, the top and bottom sashes slide up and down, compared one operator in a single hung window. Double hung windows also have a feature that allows the sashes to swing in, allowing for easy cleaning of the exterior glass panel. The screen spans the whole face of the window in double hung windows, because of the two operating sashes.

Bay windows are multi-paneled windows (usually three panels) that are angled in order to create a protrusion out of your home to fully capture the view of the outdoors. Bay windows usually have a fixed panel as the centre, and two operators (double hung or casement) as the outside panels. Bow windows are similar to bay windows except they contain four or more operating or fixed casement windows to form a more gradual curve.

Fixed windows are windows that cannot be opened. They come in a variety of different shapes to suit your home, including; octagons, hexagons, trapezoids, half rounds, full rounds, quarter rounds, ovals, ellipses, triangles, parallelograms, etc. They can be used to accent your home, or allow a huge amount of natural light into your home.

Tilt & Turn windows are a European style window. Turning the handle 90 degrees allows the window to swing into the house, similar to a door, and a 180 degree turn allows the window to tilt in from the top for ventilation. The versatility of the Tilt & Turn window allows for you to open your windows while not taking up much space.

A French door is a classic design that is traditionally used as an entryway from a patio or deck. French doors always have two operating panels, hinged at the frame which swing inward or outward. An advantage to having outswing French doors is that any wind coming toward the house will press the doors tighter into the seal, creating a tighter seal.

Lift & slide doors are similar to sliding doors, but are built with heavier duty hardware. This hardware allows for larger sliding panels compared to standard sliding doors and removes the weight of the operating panel from the rollers when not in use. This will relieve strain and weight on the rollers to ensure longevity. Larger panels keeps the glass area maximized. Lift & slide doors are also available in corner and curved configurations.

Stacking doors, also known as multi-slide doors, are variations of sliding patio doors and lift & slide doors. Stacking doors use 3+ panels to slide and stack in one direction or bi-part in the middle and stack to each side. As one panel comes to another, they collect together and continue sliding to the end to the track. Available in pocket applications, you are able to hide the panels in a wall to give a complete and full opening.
