Pass-Through

Pass-through windows create an enhanced indoor-outdoor flow for greater entertaining or open-concept living. Operated on gas struts, the window swings open like a garage door, presenting a dramatic and modern look to any space.

Glass options

Glass options

Each glass type offers different benefits depending on your preference, budget, and performance needs.

Double, or dual-pane glass consists of two glass layers with an insulating gas (like argon or krypton) in between, providing improved thermal performance and soundproofing. If you are looking for greater energy efficiency and noise reduction, ideal for the more extreme cooler or hot months, triple, or tri-pane glass adds a third layer and additional gas fill.

Other options include low-E (low -emissivity) glass, which is a special coating to reflect heat and UV rays, and laminated or tempered glass, which enhances durability and security.

Window frame material

What suits the style and functionality of your home? Consider whether vinyl, fiberglass, aluminum, vinyl metal clad, or wood metal clad is the best fit for your windows.

Vinyl

Vinyl windows are a smart choice for Okanagan homeowners looking for energy efficiency, minimal upkeep, and 25-30 years lifespan. Built from high-quality PVC, these windows resist moisture, won’t rot, and require no painting or staining, making them ideal for the region’s climate. With excellent thermal insulation, customizable designs, and lifetime warranties, vinyl windows provide lasting value and curb appeal for your home.

Durable, efficient, and low maintenance

Fiberglass

Fiberglass windows offer unmatched strength, energy efficiency, and sleek design, perfect for Okanagan homes that need performance and style. Made from durable, low-expansion materials and available in a wide range of colors, fiberglass frames resist warping, cracking, and weathering, even in extreme temperature swings. Offering excellent insulation, low maintenance requirements, and modern aesthetics, fiberglass windows are a smart, long-term investment for homeowners who value quality and performance while expecting a 40-50 year product lifespan.

Strong, stylish, and built to last

Aluminum

Aluminum windows are not as popular in the Okanagan, but could be the perfect choice for homeowners and builders seeking clean lines, slim profiles, and modern design.

Known for their strength and durability, aluminum frames allow for larger glass areas and more natural light, ideal for capturing those Okanagan views. They also deliver long-lasting structural integrity and low maintenance. With advanced thermal breaks and energy-efficient glazing options, today’s aluminum windows combine contemporary style with improved energy performance and can have a lifespan of 30-45 years with proper care and quality materials.

Sleek, modern, and built for performance

Aluminum-clad Vinyl

Vinyl metal-clad windows combine the energy efficiency and low maintenance of vinyl with the sleek, durable exterior finish of aluminum cladding. On the inside, a well-insulated vinyl frame resists warping, moisture, and temperature changes.

On the outside, aluminum cladding adds an extra layer of protection against the elements, with a clean, smooth, and modern look. This premium option is built for long-term performance in the Okanagan climate, designed to withstand seasonal extremes while enhancing your home’s appearance and value. With proper care, vinyl-clad windows offer a reliable lifespan of 30 to 40 years.

Ideal for both traditional and contemporary homes in the Okanagan, these windows combine high-end aesthetics with structural strength and energy efficiency.
