{"product_id":"44-5mm-pond-glass-window","title":"44.5mm Pond Glass Window","description":"\u003cp\u003eFour layers of 10mm toughened glass. Three EVA interlayers between them. The 44.5mm pond glass window is the specification for ponds over a metre deep or approaching 3,500mm in width, and nothing lighter is appropriate at those dimensions.\u003c\/p\u003e\n\u003cp\u003eAt 1,200mm of depth, the load on the face of a pond glass window is significant and permanent. Four-layer laminated construction, heat-soaked throughout, handles it. The three EVA interlayers each serve the same function: if the glass layer outward of each bond breaks, the fragments are held and the layers inside continue to perform. A three-layer pond glass window at 1,100mm of depth has one fewer bond in that chain. Over years of continuous water pressure that distinction is not academic. It shows up in how the installation ages.\u003c\/p\u003e\n\u003cp\u003eLarge feature ponds and serious koi breeding setups are the typical applications here. If you are building at this scale, our \u003ca href=\"https:\/\/bespokeglassproducts.co.uk\/blogs\/news\/raised-koi-pond-with-viewing-window\"\u003eraised koi pond guide\u003c\/a\u003e covers the structural and design considerations in full. Commercial installations at the outer limits of the depth and width range also land on the 44.5mm. This pond glass window is not for garden builds and it is not priced like one. Suitable for ponds up to 1,200mm deep and 3,500mm wide.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFour layers of 10mm clear toughened glass with 3 x 1.5mm EVA interlayers\u003c\/li\u003e\n\u003cli\u003eHeat-soaked for additional strength and reduced breakage risk\u003c\/li\u003e\n\u003cli\u003eAll edges polished to a professional finish\u003c\/li\u003e\n\u003cli\u003eMade to your exact dimensions\u003c\/li\u003e\n\u003cli\u003eProduction tolerance ±3mm\u003c\/li\u003e\n\u003cli\u003eAverage lead time 12 to 14 working days\u003c\/li\u003e\n\u003cli\u003eFree mainland UK delivery (exclusions apply)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003ePond Glass Window Thickness Guide\u003c\/h3\u003e\n\u003cp\u003eThe 44.5mm is the top of the range. The four lighter specifications below it are the 39mm (three layers of 12mm, up to 1,000mm deep and 3,000mm wide), the 33mm (three layers of 10mm, up to 900mm deep and 2,000mm wide), the 25.5mm (two layers of 12mm, up to 550mm deep and 1,600mm wide), and the 21.5mm at the entry point (two layers of 10mm, ponds up to 400mm deep and 1,400mm wide). If your pond dimensions fall inside any lighter specification, order that one. The 44.5mm is not a cautious upgrade. It is the specification your pond dimensions require, or it is the wrong product.
