In the SN\u00d8, the wall assembly is itself an important part of the structure. <\/span><\/p><p><span style=\"font-family: Roboto, serif\">The walls work with the roof and floor to create a strong, unified enclosure capable of resisting the forces experienced during towing. The system must withstand vibration, road impacts, wind loads and the twisting forces that occur when the trailer travels over uneven terrain. <\/span><\/p><p><span style=\"font-family: Roboto, serif\">It must also support windows, doors, cabinetry and other equipment without compromising the thermal envelope.<\/span><\/p><p><span style=\"font-family: Roboto, serif\">This means that structural strength, insulation and weather protection cannot be designed independently. Every material and connection must contribute to the performance of the complete system. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-6083fbb e-con e-atomic-element e-flexbox-base e-da2c5a7 \" data-id=\"6083fbb\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"6083fbb\" data-e-type=\"e-flexbox\" data-id=\"6083fbb\">\n    \t\t<div class=\"elementor-element elementor-element-93333b1 elementor-widget elementor-widget-image\" data-id=\"93333b1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"599\" src=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-1108-1024x767.png\" class=\"attachment-large size-large wp-image-2190\" alt=\"\" srcset=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-1108-1024x767.png 1024w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-1108-300x225.png 300w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-1108-768x575.png 768w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-1108.png 1456w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-b6ed7c8 e-con e-atomic-element e-flexbox-base e-cfb743b \" data-id=\"b6ed7c8\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"b6ed7c8\" data-e-type=\"e-flexbox\" data-id=\"b6ed7c8\">\n    \t\t<div class=\"elementor-element elementor-element-d018212 elementor-widget elementor-widget-text-editor\" data-id=\"d018212\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2><span style=\"font-family: Roboto, serif\">THE EXTERIOR LAYER: PROTECTION FROM WINTER CONDITIONS<\/span><\/h2><p><span style=\"font-family: Roboto, serif\"><br>The exterior surface is the SN\u00d8\u2019s first line of defence against snow, rain, ice, road spray and ultraviolet exposure. Its effectiveness depends not only on the exterior panels, but also on the seams, edges, fasteners and penetrations. <\/span><\/p><p><span style=\"font-family: Roboto, serif\">Water must be directed away from the trailer rather than becoming trapped around trim or inside joints. This is especially important during repeated freeze-and-thaw cycles, when moisture entering a small opening can freeze, expand and damage the assembly. <\/span><\/p><p> <\/p><h2><span style=\"font-family: Roboto, serif\">CONTINUOUS INSULATION<\/span><\/h2><p><span style=\"font-family: Roboto, serif\">Insulation slows the movement of heat from the warm interior toward the cold exterior. However, the advertised R-value of an insulation product does not necessarily represent the performance of the complete wall. <\/span><\/p><p><span style=\"font-family: Roboto, serif\">Framing, fasteners, joints and openings can create weaker areas. Gaps or poorly fitted insulation can also allow heat to escape more quickly. <\/span><\/p><p><span style=\"font-family: Roboto, serif\">The SN\u00d8 envelope is therefore considered as a continuous system. Special attention is given to corners and to the connections between the walls, roof and floor. Maintaining insulation continuity helps reduce cold interior surfaces and creates more consistent temperatures throughout the trailer.  <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-dd971d4 e-con e-atomic-element e-flexbox-base e-dd971d4-7eb21b2 \" data-id=\"dd971d4\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"dd971d4\" data-e-type=\"e-flexbox\" data-id=\"dd971d4\">\n    \t\t<div class=\"elementor-element elementor-element-3855465 elementor-widget elementor-widget-image\" data-id=\"3855465\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"598\" data-src=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111105-1024x766.png\" class=\"attachment-large size-large wp-image-2191 lazyload\" alt=\"The SN\u00d8\" data-srcset=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111105-1024x766.png 1024w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111105-300x225.png 300w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111105-768x575.png 768w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111105.png 1443w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 800px; --smush-placeholder-aspect-ratio: 800\/598;\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-47f349f e-con e-atomic-element e-flexbox-base e-47f349f-f5c66a4 \" data-id=\"47f349f\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"47f349f\" data-e-type=\"e-flexbox\" data-id=\"47f349f\">\n    \t\t<div class=\"elementor-element elementor-element-3d7dd79 elementor-widget elementor-widget-image\" data-id=\"3d7dd79\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"613\" height=\"799\" data-src=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111247.png\" class=\"attachment-large size-large wp-image-2192 lazyload\" alt=\"The SN\u00d8\" data-srcset=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111247.png 613w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111247-230x300.png 230w\" data-sizes=\"(max-width: 613px) 100vw, 613px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 613px; --smush-placeholder-aspect-ratio: 613\/799;\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-7917b94 e-con e-atomic-element e-flexbox-base e-7917b94-b03a2a7 \" data-id=\"7917b94\" data-element_type=\"e-flexbox\" data-e-type=\"e-flexbox\" data-interaction-id=\"7917b94\" data-e-type=\"e-flexbox\" data-id=\"7917b94\">\n    \t\t<div class=\"elementor-element elementor-element-8268fa3 elementor-widget elementor-widget-image\" data-id=\"8268fa3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"621\" height=\"828\" data-src=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111357.png\" class=\"attachment-large size-large wp-image-2193 lazyload\" alt=\"The SN\u00d8\" data-srcset=\"https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111357.png 621w, https:\/\/libertecaravans.com\/wp-content\/uploads\/2026\/09\/Screenshot-2026-09-24-111357-225x300.png 225w\" data-sizes=\"(max-width: 621px) 100vw, 621px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 621px; --smush-placeholder-aspect-ratio: 621\/828;\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n<div class=\"elementor-element elementor-element-ae1d156 e-flex e-con-boxed e-con e-parent\" data-id=\"ae1d156\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-239434a elementor-widget elementor-widget-text-editor\" data-id=\"239434a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2><span style=\"font-family: Roboto, serif\">CONTROLLING THERMAL BRIDGES<\/span><\/h2><p>A thermal bridge is a material or component that conducts heat more easily than the surrounding insulation.
