Unlike standard expanding foams, the low-pressure formula expands gently to fill the gap between frame and rough opening without generating the internal pressure that causes frame distortion or warping. The result is a thermally insulating, acoustically dampening, airtight seal that protects frame alignment and maintains smooth window and door operation over the long term. Specially formulated for year-round installation from 0\u00b0C to +35\u00b0C, it is particularly well suited to the climatic conditions of the Middle East, Central Asia and North Africa.<\/p>","protected":false},"featured_media":1896,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[195],"product_tag":[],"class_list":["post-974","product","type-product","status-publish","has-post-thumbnail","product_cat-pu-foam","pa_application-fields-window-door","first","instock","shipping-taxable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product\/974","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/comments?post=974"}],"version-history":[{"count":3,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product\/974\/revisions"}],"predecessor-version":[{"id":1977,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product\/974\/revisions\/1977"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/media\/1896"}],"wp:attachment":[{"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/media?parent=974"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product_brand?post=974"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product_cat?post=974"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bopinchem.com\/vi\/wp-json\/wp\/v2\/product_tag?post=974"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
