Hartley Botanic Glasshouses are single glazed in 4mm tempered safety glass, with all edges cushioned by TPR (Thermo Plastic Rubber) glazing seals, bonded to the glass. Each pane is held within its own individual framework on all sides, meaning NO glass to glass, glass to metal, nor overlapping glass contact. This method of glazing, unique to Hartley, completely eliminates glass slippage. Although it is extremely difficult to break the glass, as proven through decades of successful use in many harsh climates throughout the world, it is not possible to guarantee glass.
