Once you have built up three courses with mortar, there is no turning back. And do not leave it freestanding and unanchored: an openwork panel offers less wind resistance than a solid one, but it still needs pillars or piers every few meters and a top finish to tie it together.\u003c\/p\u003e\u003c\/blockquote\u003e ","brand":"Vetonek","offers":[{"title":"40x10x40 cm. \/ Unit \/ White","offer_id":53877293252955,"sku":"ADYBOR-CELOSIA-40x10x40-B","price":6.47,"currency_code":"EUR","in_stock":true},{"title":"40x10x40 cm. \/ Unit \/ Cream","offer_id":53877293285723,"sku":"ADYBOR-CELOSIA-40x10x40-CR","price":6.47,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/9698\/8257\/files\/cubrepilares-4.jpg?v=1787639143","url":"https:\/\/vetonek.com\/en\/products\/concrete-breeze-block-40x10x40-cm-openwork-enclosure-that-provides-ventilation-and-shade","provider":"Vetonek","version":"1.0","type":"link"}
