This commercial glass greenhouse is built for growers who need stable light and reliable winter performance. The 4 mm toughened double glazing diffuses daylight evenly across the crop while cutting infrared heat loss, and the sealed air gap slows overnight cooling in cold climates. A hot-dip galvanized aluminium frame carries snow loads up to 50 kg/m2 without sagging. Roof vents and side louvres control humidity, which matters in hydroponic bays where disease pressure rises quickly. The greenhouse ships as a modular kit: spans of 6 m, 8 m or 10 m combine with lengths from 30 m to 60 m, and every section bolts together without field welding. Typical uses include year-round vegetables, cut flowers, nursery propagation and commercial hydroponics.
Glass greenhouses hold light and heat longer than film or panel covers, which is why commercial growers in cold and temperate regions keep choosing them. This model pairs 4 mm toughened double glazing with a hot-dip galvanized aluminium frame to deliver even light diffusion, controlled heat loss and a structure rated for 50 kg/m2 of snow. It is designed for year-round vegetable, flower and hydroponic production.
Each pane is 4 mm toughened glass, tempered for impact resistance and set in a sealed double glazing unit. The air gap between the two panes slows heat transfer, so overnight temperatures stay more stable than with single glazing. The frame is hot-dip galvanized aluminium, a combination chosen for corrosion resistance in humid growing rooms and for a stiffness that keeps roof geometry under load. All steel sections are galvanized after fabrication, which protects cut ends and bolt holes as well as the visible surfaces. The unit is manufactured to recognised NEN glazing and structural practice, and growers can follow current commercial greenhouse reporting on FreshPlaza.
The greenhouse ships as a modular kit. Panels, frame sections and fittings arrive pre-drilled and labelled, so assembly on site needs no field welding. A small crew can follow the supplied layout drawing and bolt each bay together, then repeat the module along the length of the house. Maintenance is mostly inspection: check seals at the start of each season, clean glass surfaces so light transmission stays high, and verify that vent actuators move freely. Galvanized surfaces need no repainting under normal use.
These houses suit year-round vegetable cultivation, where stable winter temperatures protect margins, and cut flower production, where even light improves grade consistency. Nursery propagation benefits from the controlled humidity that roof vents and louvres provide.
In hydroponic operations, the sealed glazing reduces heat loss in winter while the ventilation system handles the moisture load from open water surfaces. See our glass greenhouse range, the Venlo glass greenhouse with roof vent and cooling pad, and our hydroponics system range for complete project planning.
It uses 4 mm toughened glass in a sealed double glazing unit. The toughening process raises impact resistance, and the air gap between panes reduces heat loss during cold nights.
The frame is rated for snow loads up to 50 kg/m2. Heavier local requirements can be met with a customized frame, so tell us your design snow load when requesting a quotation.
With normal use and routine inspection, the galvanized structure is expected to serve for 15 to 20 years. The covering glass performs for 15 years or more depending on handling and local conditions.
We provide a 10-year structural warranty and a 5-year anti-corrosion warranty. Film or covering warranty is separate and depends on the cover type selected.
