Applied using a foam gun or straw applicator, they expand slightly after application and cure through reaction with moisture in the air, forming a strong and long-lasting bond. In terms of performance, foam adhesives share many characteristics with standard PU foams, including <strong>excellent thermal and sound insulation<\/strong>.<br> <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Do Foam Adhesives Differ From Traditional Construction Foams?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The key differences are the foam adhesive\u2019s <strong>higher froth density and lower post-expansion<\/strong>. The higher froth density during application guarantees a strong and even bond between glued surfaces, while the controlled post-expansion allows materials such as insulation boards to be fixed securely without the risk of warping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With an average <strong>bonding strength of 0.12 MPa<\/strong>, Penosil foam adhesives have strong adhesion to most common building materials such as: <\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column has-background is-layout-flow wp-block-column-is-layout-flow\" style=\"background-color:#f6f6f6\">\n<ul class=\"wp-block-list\">\n<li>Insulation boards<\/li>\n\n\n\n<li>Hard wool<\/li>\n\n\n\n<li>Concrete<\/li>\n\n\n\n<li>Wood<\/li>\n\n\n\n<li>Plasterboard<\/li>\n\n\n\n<li>Construction panels<\/li>\n\n\n\n<li>Bricks<\/li>\n\n\n\n<li>Blocks, etc.<\/li>\n<\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/penosil.com\/wp-content\/uploads\/sites\/17\/2026\/08\/materjalide-list-1.png\" alt=\"\" class=\"wp-image-38347\" style=\"aspect-ratio:1.186327139252122;width:355px;height:auto\"\/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, <strong>all Penosil foam adhesives<\/strong> are tested and certified by independent third parties. They meet strict emission standards, including<strong> EC1+ <\/strong>and<strong> M1<\/strong>, and, depending on the product, also comply with <strong>EOTA<\/strong> or <strong>ASTM<\/strong> certification requirements.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/penosil.com\/wp-content\/uploads\/sites\/17\/2026\/08\/Certificates.png\" alt=\"\" class=\"wp-image-38299\" style=\"width:537px;height:auto\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, foam adhesives have become a <strong>practical and cost-effective alternative<\/strong> to traditional bonding methods such as mortar, screws and cartridge-based adhesives. Their <strong>fast application, strong adhesion and excellent insulating properties<\/strong> make them a versatile solution for a wide range of construction tasks.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Advantages Over Traditional Mortar<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Foam adhesives offer several advantages over traditional bonding methods such as mortar. They are much faster to use, create no mess during application, and require significantly less product.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/penosil.com\/wp-content\/uploads\/sites\/17\/2026\/08\/Foam-adhesive-banner.png\" alt=\"Foam adhesive banner\" class=\"wp-image-38307\" style=\"aspect-ratio:1.0281533322729441;width:190px;height:auto\"\/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">1. <strong>Material Savings<\/strong><\/h3>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f6f6f6\">A\u00a0<strong>1 L can<\/strong> of foam adhesive\u00a0<strong>equals\u00a025 kg of cement<\/strong>. Foam adhesives are lighter, much easier to handle and have a much lower transportation carbon footprint.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>2. <strong>Speed<\/strong><\/h3>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f6f6f6\">Compared to traditional mortar, foam adhesives significantly reduce installation time. The foam adhesives are ready-to-use; simply shake the can and apply. Tack-free time is around <strong>7 minutes<\/strong>, load time is around <strong>2 hours<\/strong>, and curing is significantly faster than for mortar-based solutions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>3. <strong>Excellent Insulation Properties<\/strong><\/h3>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f6f6f6\">Using foam adhesives is an effective way to reduce thermal bridges in buildings. With thermal conductivity as low as <strong>0.033 W\/(m\u00b7K)<\/strong> and sound insulation value as high as <strong>62 dB<\/strong>, foam adhesives are one of the insulation materials with the lowest thermal conductivity available.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br>4. <strong>Versatility<\/strong><\/h3>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#f6f6f6\">Foam adhesives can fill gaps and accommodate structural movement. Unlike mortar, which typically requires installation temperatures above +5\u00b0C, many foam adhesives can be applied <strong>below 0\u00b0C<\/strong>.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Choosing the Right Foam Adhesive<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/penosil.com\/wp-content\/uploads\/sites\/17\/2026\/08\/Adhering_Family_Foams_Global_2025_0130.png\" alt=\"\" class=\"wp-image-38310\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\">When choosing a foam adhesive, the most important factors to consider are <strong>material compatibility, application type and working temperature<\/strong>.
