The result is a rolling door that meaningfully reduces heat transfer and airborne noise versus a single-skin curtain &mdash; the right choice for climate-controlled warehouses, chilled areas, conditioned manufacturing and any opening where energy loss through the door matters.<\/p>\n          <p class=\"text-lead\">The extruded aluminum skins give the panel rigidity and corrosion resistance, while the foam core delivers the thermal and acoustic benefit. RAX manufactures the insulated slats on its auto PU foam panel line, finishes them to any RAL color, and confirms the achievable thermal performance against your opening on the technical layout.<\/p>\n          <p class=\"text-muted\"><small>RAX-company facts on this page &mdash; materials, 100,000-cycle fatigue testing, certifications held, warranty and lead time &mdash; are from RAX Door Technology&#8217;s approved brand brief.
