Aluminum

Aluminum windows are a great option for custom homes, contemporary building styles, and commercial window applications.

Fibreglass

Fibreglass provides low levels of conductivity without the need for thermal breaks. The frames are more energy-efficient than aluminum or vinyl windows, allowing less heat or cold to travel through the frame material itself.

Vinyl

Vinyl windows are usually the least expensive choice and are suitable for many applications. In lower-quality models, the weatherstripping is not durable, and some of the plastic parts may break.

Wood

Wood windows are more expensive than vinyl windows and periodically need to be sealed with paint or finish to prevent rotting and sun damage.

Glass

Whether floating, safety, insulated glass unit (IGU), low-emissivity glass, etc. – a frameless window is just as it is described. Frameless. A seamless option that has no obvious frame around the perimeter.

Visual Light Transmittance (VLT)

Visible light transmission is the percentage or fraction of visible light that passes through the glazing system, as opposed to being reflected or absorbed. It is somewhat of a filter for reducing the intensity of exterior daylight conditions.

Solar Heat Gain Coefficient (SHGC)

The SHGC rating represents a small fraction of the amount of solar radiation across the entire spectrum directly transmitted and absorbed by the glass portion of a window. It can give you an idea of how much solar heat and sunlight will be released in your home.
