Toughened Glass Glazing

Toughened glass, also known as tempered glass, is a high-strength and durable glazing material that is ideal for greenhouses. It undergoes a special heat treatment process that enhances its resistance to impact, making it less likely to break or shatter. In the rare event of breakage, toughened glass crumbles into small, granular pieces, reducing the risk of injury. Gardeners and plant enthusiasts value toughened glass for its safety, longevity, and ability to provide a clear and well-lit environment for optimal plant growth.

The 12ft x 12ft Janssens Mur Dwarf Wall Greenhouse is a large, extra strong greenhouse that will make a real statement in your garden as a focal point.

You'll not only get stylish Victorian looks with the roof cresting and finial but you will also get full modern box section construction, vital for weather resistance, especially in very strong storms and winds. The ornate crestings and finials match the greenhouse colour, whether you choose a green or black powder-coated frame finish.

Pick from a green or black powder-coated finish to suit your garden or personal style preferences. Both Hinged and Sliding Double and Single Doors are available as options below to fully customise your greenhouse.

All Janssens Mur Greenhouses are built around a strong box-section aluminium frame, with 4mm Toughened Glass held in with proper rubber glazing gasket to take on the worse of UK weather!
