Anyone who values <strong>sound insulation<\/strong> or additional <strong>thermal insulation<\/strong> in interior rooms must actively ask for it &#8211; and <strong>usually pay extra<\/strong>. Here we report from our own experience on what to look out for and which insulation measures make sense.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">When we asked what was going between the timbers that make up the walls, our builder looked at us a little puzzled: &#8220;Nothing. The walls are sealed hollow, you can&#8217;t see them&#8221;. OK then, and <strong>what about the background noise <\/strong>from the neighboring rooms?   <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without further ado, we decided to <strong>pay USD 580 for an upgrade<\/strong> and have these walls insulated. After all, we don&#8217;t necessarily want to hear everything that happens in the neighboring rooms. In retrospect, it is still very hard to hear. I can&#8217;t imagine what it would have been like if we hadn&#8217;t had the insulation.   <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ceilings are insulated as standard, but the <a href=\"https:\/\/www.florida-scout.com\/en\/house-construction-report\/roof-decking\/\" data-type=\"post\" data-id=\"7021\">roof<\/a> is generally not, although we will have this done later. As no reinforced concrete is used in the ceilings as in Germany, this insulation <strong>keeps the heat away from the roof truss<\/strong>.   <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Insulation of

class=\"wp-block-paragraph\"><strong>Insulating interior walls<\/strong> is not standard in Florida &#8211; even in new construction. Generally, the spaces between the wood stud walls are simply left empty unless the builder specifically requests <strong>acoustic or thermal insulation<\/strong>. Typically, a simple glass wool (R-11 or R-13) is inserted in what is known as an &#8220;interior wall insulation upgrade&#8221;, usually purely for reasons of <strong>sound insulation<\/strong>. The effect is noticeable, but should not be compared with the sound insulation of European solid walls.   <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bathroom walls or partition walls to utility rooms are also <strong>not insulated<\/strong> as standard, although noise from ventilation, washing machines or <a href=\"https:\/\/www.florida-scout.com\/en\/house-construction-report\/plumbing-rough-in\/\" data-type=\"post\" data-id=\"6872\">water pipes <\/a>can occur there. Insulating these areas is also considered a costly upgrade &#8211; often in the range of USD 300 to 1,000, depending on the size and contractor. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anyone who values a little more peace and quiet and privacy should therefore <strong>make specific inquiries during the planning phase<\/strong> as to which walls can be sensibly insulated &#8211; and how much it will cost.

For <strong>thermal insulation <\\\/strong>, calcium silicate, wood fiber or polyurethane (PUR\\\/PIR) is more effective - especially where space is limited.
