{"product_id":"diamond-weep","title":"Diamond Weep","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Manthorpe G953 Diamond Weep is a robust, discreet perp-end ventilator for cavity wall drainage. Its distinctive diamond-shaped profile increases the drainage flow rate along the base of the channel, promoting self-cleaning and helping clear debris build-up rather than letting it block the outlet,  keeping the cavity draining freely over the life of the wall.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFitted into an open perpendicular joint above cavity trays, DPCs and over openings, the diamond outlet finishes flush with the brickwork for quick, tidy detailing into the mortar joint, while the tapering outlet is designed for easy cleaning. Ribs along the angled outer walls form a strong mortar key within the perp end for a secure fit in the outer leaf. The rear opening stands a full 65mm,  the height of the perpend joint, in line with NHBC Technical Extra 17, for an optimum drainage inlet from within the cavity, and the minimum 4mm opening is ample for water drainage while staying small enough to keep large insects out.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMoulded from durable polypropylene, it's a quick, one-person fit straight into the course as the brickwork goes up, with a BIM object available for specifiers. Available in clear and the full range of colours to match any brick and mortar finish.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDiamond-shaped profile increases drainage flow rate and promotes self-cleaning, clearing debris build-up\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFlush outlet for quick, discreet detailing into the mortar joint\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFull 65mm rear opening for optimum drainage inlet, in line with NHBC Technical Extra 17\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOne-person installation, saving time on site\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIn line with Building Regulations Part C 5.5(c), weep holes should be positioned every 900mm above a low-level damp proof course to help transfer moisture through the external leaf. \u003c\/li\u003e\n\u003cli\u003eBed size: 102.5mm\u003c\/li\u003e\n\u003cli\u003eCoursing height: 75mm\u003c\/li\u003e\n\u003cli\u003eMinimum opening: 4mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Manthorpe","offers":[{"title":"Terracota","offer_id":57749937094988,"sku":"BMD6640","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"Clear","offer_id":57749937127756,"sku":"BMD6641","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"Buff","offer_id":57749937160524,"sku":"BMD6642","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"Grey","offer_id":57749937193292,"sku":"BMD6643","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":57749937226060,"sku":"BMD6644","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"White","offer_id":57749937258828,"sku":"BMD6645","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"Blue\/Black","offer_id":57749937291596,"sku":"BMD6646","price":28.57,"currency_code":"GBP","in_stock":true},{"title":"Brown","offer_id":57749937324364,"sku":"BMD6647","price":28.57,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/manthorpe-wall-drainage-terracota-diamond-weep-1243343672.avif?v=1781020008","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/diamond-weep","provider":"Construction Supplies UK","version":"1.0","type":"link"}
