Windows
4300 series casement
Inspired by Westcoast Contemporary design, and influenced by building science, Westeck’s line of windows provides an innovative solution for today’s energy-efficient home.
The Westeck Westcoast Contemporary line of windows allow for bigger and better views, cleaner lines, cleaner glass, easier operation and industry-leading safety.
The 4300 series window is a high-performance PVC framed casement, awning and fixed window system. This innovative window is designed for maximizing the view, ease of operation and impressive thermal performance.
If you or your architect can design it, our specialty department can most likely build it.

Solid coated colours
Colour with confidence
Match every window and door to your vision with RAL specifications, custom colours, or Westeck’s extensive standard palette. E-Coat Colourwise Performance Vinyl leads the industry in water-based coating and staining technology. With a 20-year colour warranty on vinyl products, it delivers long-lasting durability. Heat-reflective pigments reduce heat gain, even in dark colours.
This finish exceeds AAMA 615 performance standards and meets EPA safety requirements. It’s non-toxic, free from lead, isocyanates, and NMP. At Westeck Windows & Doors, we use E-Coat Colourwise Performance Vinyl Diamond Coat for a high-performance, eco-friendly finish.

Customize your colour
At Westeck, we take pride in ensuring the colours you see are as accurate as possible, which is why our digital swatches are calibrated using state-of-the-art spectrometry for precise matching to our actual products. However, the colours displayed on your screen or printer may vary due to the limitations of individual devices. For the most accurate representation, we recommend viewing these samples on an iPad or iPhone. For critical colour matching, visiting our showroom or requesting physical samples is always the best choice to guarantee satisfaction.
We also work with outside paint vendors for custom matching should this be a requirement.

The world’s first flexible window screen
Simple design
Our revolutionary design utilizes a PVC coated, high-performance spring steel frame. However, innovation does not need to be complex, so you will not find unnecessary attachment hardware on FlexScreen.
Damage resistant
We were tired of bent aluminum frames, scratched paint and broken hardware. So we built a window screen that can be thrown from the top of a five-storey building without being damaged.
Beautifully invisible
FlexScreen hides in the window screen pocket, drastically improving sightlines and eliminating the need for colour matching.
