The lower the thermal resistance, the higher the efficiency of the underfloor heating.<\/p>\n<p><strong>We recommend using the following products for laying on an underfloor heating system:<\/strong><\/p>\n<ul>\n<li><a href=\"\/en\/produkt\/underlays-parquet-laminate\/selitflex-underlays\/selitflex-1-6-mm-aquastop-faltplatte\/\">SELITFLEX 1,6 mm AquaStop<\/a><\/li>\n<\/ul>\n<p>Alternative<\/p>\n<ul>\n<li><a href=\"\/en\/produkt\/underlays-parquet-laminate\/selitpro-underlays\/selitpro-xpo-2-mm-aquastop\/\">SELITPRO XPO 2 mm AquaStop<\/a><\/li>\n<li><a href=\"https:\/\/www.selit.com\/en\/produkt\/underlays-parquet-laminate\/selitpro-underlays\/selitpro-hd-2-mm-aquastop\/\">SELITPRO HD 2 mm AquaStop<\/a><\/li>\n<\/ul>\n<p>[\/vc_toggle][vc_toggle title=&#8221;Which underlay can I use on wooden floors?&#8221; style=&#8221;arrow&#8221;]On wooden bases, installation takes place without the moisture protection film in principle. If the base is very uneven, we recommend using special wood fillers (partly fibre-reinforced) or particle boards, which are installed on top of the old wooden boards with an intermediate layer of PE foam. Then install the impact sound insulation on top of this without moisture protection.[\/vc_toggle][vc_toggle title=&#8221;When do I need moisture protection?&#8221; style=&#8221;arrow&#8221;]If you are laying flooring on screed or concrete, moisture protection is absolutely essential. Otherwise, rising residual moisture from the base can cause serious damage to your laminate or wood flooring.<\/p>\n<p>All our products with AquaStop\u2122 technology offer suitable moisture protection in the form of a laminated AquaStop\u2122 film surface. The advantage of this is that it eliminates the need to install a vapour barrier too.[\/vc_toggle][vc_toggle title=&#8221;Can I install it on carpet?&#8221; style=&#8221;arrow&#8221;]We generally advise against installation on existing carpets. For high-pile velour carpets, you risk breaking the click connections due to lack of pressure stability. In addition, there is a high likelihood of mould formation with installation on carpet.<\/p>\n<p>The <a href=\"https:\/\/www.eplf.com\/en\" target=\"_blank\" rel=\"noopener noreferrer\">EPLF Merkblatt<\/a> also recommends removing existing carpet (Paragraph 5.4.5).[\/vc_toggle][vc_toggle title=&#8221;Can I lay double layers of underlays?&#8221; style=&#8221;arrow&#8221;]In general, we do not recommend the use of double layers of underlay. The 2 layers impair the pressure stability of the underlay and the resulting friction may lead to undesirable floor noises.[\/vc_toggle][vc_toggle title=&#8221;What do the individual test marks mean?&#8221; style=&#8221;arrow&#8221;]<strong>T\u00dcV Cert DIN EN ISO 9001<\/strong><\/p>\n<p><strong>Zertifikat: 01 100 84025<\/strong><br \/>\nThe T\u00dcV-Cert certification body of T\u00dcV Rheinland certifies SELIT for the scope &#8220;Development, production and sale of innovative insulation materials for ceilings, walls and floors and <strong>the introduction and application of a quality management system<\/strong> in accordance with DIN EN ISO 9001:2008.<\/p>\n<p><strong>SELIT stands for quality and reliability &#8211; for more than 30 years!<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>\u00dc-Zeichen<\/strong><\/p>\n<p>The mark of conformity in the German Federal States identifies regulated and non-regulated construction products that comply with the underlying technical regulation, the national technical approval, the general supervisory authority test certificate, or the approval in individual cases.<\/p>\n<p>In Germany, this is also known as the &#8220;\u00dc mark of conformity&#8221;.

Products made of polystyrene (such as SELITAC<sup>\u00ae<\/sup> and SELITPRO<sup>\u00ae<\/sup> Serie) are the first choice in this case.[\/vc_toggle][vc_toggle title=&#8221;Do underlays also provide thermal insulation?&#8221; style=&#8221;arrow&#8221;]For cold floors, especially in basement areas, underlays contribute to thermal insulation. The rule is: the thicker the material, the better the insulation. Even underlays as thin as 5 mm, such as SELITAC\u00ae 5 mm, provide significantly increased foot warmth. SELITFLEX\u00ae 10 mm Thermo achieves top performance in terms of thermal insulation.[\/vc_toggle][vc_toggle title=&#8221;How do I find the best underlay?&#8221; style=&#8221;arrow&#8221;]The easiest way to find the right underlay is to use the \u201cSELIT Product Advisor\u201d, which is our app. This app is for <a href=\"https:\/\/itunes.apple.com\/de\/app\/selit-produktberater\/id1189141393\" target=\"_blank\" rel=\"noopener noreferrer\">iOS<\/a> and <a href=\"https:\/\/play.google.com\/store\/apps\/details?id=de.selit.selit\" target=\"_blank\" rel=\"noopener noreferrer\">Android<\/a> and enables you to scan the flooring you have purchased and find the perfect underlay for it.<\/p>\n<p>You can also find a product advisor tool here on our website. Just answer a few questions and get a recommendation straight away.[\/vc_toggle][vc_toggle title=&#8221;Can the underlay be affixed with adhesive?&#8221; style=&#8221;arrow&#8221;]underlays like SELITPRO\u00ae, SELITAC\u00ae, SELITFLEX\u00ae and SELITBLOC\u00ae are designed for the floating installation of laminate, wood flooring and vinyl click flooring and must not be firmly affixed to the base.<\/p>\n<p>For easier installation, you can use SELITstop\u00ae Aluminium-Foil Sealing Tape.[\/vc_toggle][vc_toggle title=&#8221;Do underlays need to be acclimatised?&#8221; style=&#8221;arrow&#8221;]Unlike floor coverings (laminate, wood flooring and vinyl), underlays do not have to be acclimatised in the room but can be installed immediately after purchase.<\/p>\n<p>Decorative floors must be acclimatised in the installation room for at least 24 hours and 48 hours is preferable. Please follow the instructions provided by the floor manufacturer.[\/vc_toggle][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>\u2026<\/p>\n","protected":false},"author":7,"featured_media":0,"parent":4772,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-4755","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/pages\/4755","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/comments?post=4755"}],"version-history":[{"count":26,"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/pages\/4755\/revisions"}],"predecessor-version":[{"id":5564,"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/pages\/4755\/revisions\/5564"}],"up":[{"embeddable":true,"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/pages\/4772"}],"wp:attachment":[{"href":"https:\/\/www.selit.com\/en\/wp-json\/wp\/v2\/media?parent=4755"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
