Rousham Orangery — Lantern

QELNAVOR Glass — winter, postponed indefinitely

Orangeries are optimism with a U-value; the Rousham measures both — Ug 1.0 insulated glass, honest heating loads, and a lantern-roof option that crowns the garden the way conservatories used to promise.

Orangeries are optimism with a U-value, and ours measure it: thermally broken aluminium or laminated timber frames, insulated safety glass to Ug 1.0, condensation managed by design rather than towel, and ridge details that shed snow without theatrics. Automatic roof vents and shading run quietly; winter runs outside.

Design & Craft

• Winter citrus regime: frost-free with honest heating loads
• Thermally broken aluminium or laminated timber frames
• Statutory 24-month warranty
• Condensation managed by design: ventilation, breaks, drainage
• Insulated safety glass to Ug 1.0; laminated where overhead
• Automatic roof vents and shading options run quietly

Specifications

Care

Lubricate hinges and vent gear yearly with the supplied grease, keep drainage channels clear, and wash frames with neutral cleaner. The orangery ages by staying exactly the same.

Questions, Answered

What about condensation?
Managed by design: ventilation paths, thermal breaks and drainage details. Persistent misting between panes is a warranty matter — glass units are available as spare parts.

Does it attach to any house?
Winter gardens are surveyed first — wall build, damp course, foundations — then engineered to the house. The flashing details are ours; the house's dignity stays its own.
