The building came up for renovation at the same time as the Amos Anderson art museum was looking for a site for a new building. This gave rise to a project to simultaneously renovate the popular Lasipalatsi and to construct a new, mainly underground, museum building. One special characteristic of the project was the need to support the old clocktower in the Lasipalatsin aukio square, and this became one of the most demanding phases in the entire project.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/foamit.fi\/wp-content\/uploads\/2019\/01\/001-DSCF3346-Pano-AmosRex-PaavoPykalainen-1024x463.jpg\" alt=\"\" class=\"wp-image-772\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The museum\u2019s load-bearing frame was built around and beneath the clocktower, which was supported for the duration of the work. Several other tasks were underway while the frame was being constructed. These tasks included waterproofing, which was included in the contract awarded to KerabitPro Oy.<\/p>\n\n\n\n<blockquote class=\"blockquote\" class=\"wp-block-quote is-style-default is-layout-flow wp-block-quote-is-layout-flow\"><p>The beginning of the project was spent completing waterproofing of the vertical arches underground. After that, we were able to build the courtyard deck, with its demanding structure and shape.<\/p><cite class=\"blockquote-footer\">Production Director <strong>Ari Hoikkala<\/strong>, KerabitPro Oy<\/cite><\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Foam glass aggregate lightens the deck cover<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The frame of the cast-in-situ courtyard deck, which is also the museum\u2019s roof, consists of horizontal sections with cupolas at regular intervals. The cupolas have a maximum gradient of 30\u00b0, and they act as skylights for the museum. At their bases, the cupolas have a corresponding structure to the surrounding horizontal areas. The courtyard deck structure consists of a three-ply waterproofing membrane, three extruded thermal insulation plates, a subsurface drain mat, filter fabric and a layer of foam glass averaging 0.5\u00a0metres in thickness.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/foamit.fi\/wp-content\/uploads\/2019\/01\/036-DSCF3258-AmosRex-PaavoPykalainen-1024x683.jpg\" alt=\"\" class=\"wp-image-771\" \/><\/figure>\n\n\n\n<blockquote class=\"blockquote\" class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>The foam glass aggregate acts as a lightening material for the structure. Lightening is essential because the structure has several layers, and the total load must not be too large. Foam glass is the best option for a lightening material because it also has good load-bearing capacity in addition to its other benefits. <\/p><cite class=\"blockquote-footer\"><strong>Teemu Rahikainen<\/strong>, responsible for structural design, Sipti Oy<\/cite><\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">All of the aforementioned structural layers, as well as the reinforced concrete slab made on top of them, were included in KerabitPro\u2019s contract. \u201cThe steep sections required particularly careful installation,\u201d says Hoikkala.<\/p>\n","protected":false},"featured_media":5291,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"country":[],"news-category":[120],"class_list":["post-5496","news","type-news","status-publish","has-post-thumbnail","hentry","news-category-building-construction"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>The Lasipalatsi courtyard deck forms the roof of the Amos Rex art museum - Foamit Finland<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/foamitgroup.fi\/en\/news\/the-lasipalatsi-courtyard-deck-forms-the-roof-of-the-amos-rex-art-museum\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"The Lasipalatsi courtyard deck forms the roof of the Amos Rex art museum - Foamit Finland\" \/>\n<meta property=\"og:description\" content=\"Lasipalatsi, a building in central Helsinki, was originally erected as a temporary structure more than 50 years ago.
