Zerav Glasshouse 6

QELNAVOR Glass — winter, postponed indefinitely

Serious gardeners outgrow polycarbonate; the Zerav is the graduation — cold, cool or warm house regimes stated plainly, automatic vents that work in August, and lines that flatter the kitchen garden they serve.

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

• Condensation managed by design: ventilation, breaks, drainage
• Frost-deep foundations; gaskets stocked fifteen years
• Toughened panes sized for hail honesty
• Victorian growing lines with modern thermal manners
• Automatic roof vents and shading options run quietly
• Insulated safety glass to Ug 1.0; laminated where overhead

Specifications

Care

Wash glass with water and a soft blade twice a year; clear gutters and check vent seals each autumn. Gaskets and glass units are stocked for fifteen years — condensation between panes is a warranty conversation, not a mystery.

Questions, Answered

Is it warm enough in winter?
Insulated glass to Ug 1.0 and thermally broken frames hold a winter garden comfortably above frost, and heating options make it a January room. Growing houses state their own regimes honestly.

Will it overheat in summer?
Not with the shading and ventilation designed in: automatic roof vents, shading options and door placement are sized to the glass area. The listing states the package; summer states its gratitude.

The QELNAVOR Promise
