Refined Vertical Styling with Enhanced Insulation

The Fort 20mm Chester Vertical Standard Rib with Window delivers refined vertical styling through its carefully proportioned standard-width ribs, creating an elegant aesthetic that suits both traditional and contemporary UK properties. Combined with 20mm insulated construction and twin glazed windows for natural light, this door provides an ideal balance of visual appeal, thermal performance, and practical functionality for discerning homeowners.

The standard rib width creates a refined, sophisticated appearance with evenly-spaced vertical lines running the full door height. This proportioning suits properties seeking understated elegance rather than bold contemporary statements, offering timeless styling that enhances rather than dominates your property's facade. The vertical orientation efficiently manages rainwater whilst the ribbed profile adds subtle visual depth and character. Twin windows in the upper section flood your garage with daylight, transforming it from dark storage into a bright, versatile space perfect for workshops, hobbies, or multi-purpose use. With 20mm double-skin insulated construction delivering excellent thermal efficiency and condensation resistance, this door creates comfortable year-round conditions whilst protecting stored contents. The side-hinged configuration preserves internal space, with outward-opening doors eliminating overhead mechanisms for maximum ceiling height. Single-leaf access provides everyday convenience. Choose from 50/50 or 1/3-2/3 split configurations, with 34 RAL colours available.
