Engineering & Specifications

VDK Ultra Shaped Windows are built to the same high standards—fusion-welded corners, multi-chamber frames, and premium uPVC construction for lasting performance and energy efficiency.

Fusion-Welded Corners

Frame corners are heat-fused into a single, seamless piece — not screwed or glued. This creates an airtight, watertight joint that maintains structural integrity for the life of the window.

Multi-Chamber Frame Design

The frame profile contains multiple hollow chambers that trap air, creating a natural thermal barrier. This design significantly reduces heat transfer through the frame itself.

Premium uPVC Construction

Made from high-quality unplasticized PVC that resists fading, warping, cracking, and rot. Unlike wood, it never needs painting or staining. Unlike aluminum, it won't corrode or conduct cold.

Warm Edge Spacer System

Advanced spacer technology between glass panes reduces condensation at the glass edge and improves overall thermal performance, keeping the interior glass surface warmer in winter.
