Colour with Confidence
Match every window and door to your vision with Westeck’s extensive standard colour palette, custom RAL specifications, or custom colour matching. Whether you’re looking for a timeless neutral, a bold architectural statement, or a colour unique to your project, we can match virtually any colour to bring your vision to life.
Westeck utilizes E-Coat Colourwise Performance Vinyl, an industry-leading water-based coating and staining technology designed to deliver exceptional durability and long-lasting beauty. Backed by a 15-year colour warranty on vinyl products, it helps maintain a vibrant, consistent finish for years to come. Heat-reflective pigments reduce heat absorption, even in darker colours, helping to enhance long-term performance.
This finish complies with FGIA/AAMA 615 and 625 performance standards and meets EPA safety requirements. It is non-toxic and free from lead, isocyanates, and NMP. At Westeck Windows & Doors, we use E-Coat Colourwise Performance Vinyl Diamond Coat to provide a high-performance, environmentally responsible finish.
Standard Colours
Choose from Westeck’s carefully curated selection of standard colours or create a completely custom look with colour matching and RAL specifications. Our team can match virtually any colour to complement your home’s architecture, design style, or project requirements.
Customize Your Colour
At Westeck, we take pride in delivering colours that closely match your expectations. Our digital swatches are calibrated using advanced spectrometry technology to provide accurate colour representation and consistency across our product offering.
Wood stain finishes are available upon request.
Glass
Our window and sliding systems can be optimized for energy efficiency by choosing a combination of our glass and coating options.
Low-E glass
Low-E glass maximizes natural daylight while delivering excellent thermal performance. Its neutral appearance allows for high visible light transmission, creating bright, comfortable living spaces without compromising energy efficiency.
Ideal for projects that prioritize clear views, natural light, and year-round comfort.
Solar control glass
Solar Control Glass is designed to help manage heat gain and improve indoor comfort throughout the year. By reducing the amount of solar energy entering the home, it helps minimize overheating during warmer months while maintaining excellent insulating performance during colder seasons.
This advanced glazing option is ideal for large expanses of glass, south- and west-facing elevations, and projects where maximizing comfort and energy efficiency is a priority.
Laminated safety glass
Laminated Safety Glass consists of two or more panes of glass permanently bonded together with a durable interlayer. This construction creates a stronger, safer glazing solution that continues to act as a protective barrier even if the glass is broken.
When breakage occurs, the interlayer helps hold the glass fragments together, reducing the risk of injury from shattered glass and enhancing security. Laminated glass can also improve sound control by reducing outside noise transmission and helps block up to 99% of harmful UV rays, helping protect interior furnishings from fading.
Laminated Safety Glass is commonly used in applications where enhanced safety, security, and acoustic performance are desired.
Decorative glass
Decorative Glass offers the perfect balance of privacy, natural light, and design flexibility. Available in a wide variety of patterns, textures, and styles, decorative glass can enhance the character of your home while maintaining privacy in entryways, bathrooms, and other living spaces.
Options range from subtle textured patterns to intricate decorative and leaded glass designs, allowing you to create a look that complements your home’s architecture and personal style.
Whether you’re seeking increased privacy, enhanced curb appeal, or a distinctive design feature, Decorative Glass provides a beautiful and functional solution.
