Insulated Sectional Overhead Doors – Versatile Solutions for Every Application
Insulated sectional overhead doors are now a top choice for properties across the UK, offering outstanding performance benefits that set them apart from other door types. Whether for domestic garages or large commercial premises, sectional doors deliver impressive insulation, high security, and reliable weather protection thanks to their advanced multi-panel design.
A sectional overhead door is constructed from several robust, double-skinned panels—typically steel or aluminium—that interlock to form a strong, energy-efficient barrier. These panels travel vertically on roller wheels up either side, and the door can be designed to turn into the building, rise directly upwards, or follow custom trajectories depending on available headroom. Glazed panel options allow for additional light and visibility where required.
Users often confuse sectional doors with roller shutter doors, but they are distinctly different in build and operation. Sectional doors offer smooth, quiet running, and minimal contact between moving parts. Closed panels are joined with high-quality seals for maximum insulation and safety, including built-in anti-finger-trap protection.
Performance Advantages
Sectional overhead doors provide exceptional thermal insulation, with certified U-values and acoustic performance that help maintain comfortable interiors and reduce external noise. Security certifications, including Secured by Design options, reinforce protection against intrusion, while weathersealing prevents dust, leaves, and debris from entering. For projects needing advanced insulation, panels up to 80mm thick are available.
Large openings are easily accommodated, with sectional doors available up to 10,000mm wide and 8,000mm tall. All doors feature excellent spring balancing for easy manual use, with the option of electric operation for added convenience—manual override is always included for emergencies.
Custom Colour & Finishes
The use of galvanised steel or aluminium means customisation is virtually unlimited. Choose from classic powder-coated finishes, realistic woodgrain laminates, or bespoke printed designs including logos and imagery—technology that ensures long-lasting vibrancy and durability. Because panels move without rubbing against one another, the finish remains pristine over time.
