{"product_id":"the-sealgrid-epdm-expansion-sealing-strip","title":"The Sealgrid | EPDM Expansion Joint Sealing Strip","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp style=\"line-height:1.8;margin-bottom:18px;\"\u003eWater does not enter through walls. It enters through the joints between them, and specifically through joints that were sealed once with a material that could not follow the structure as it expanded, contracted and settled. The Sealgrid is a strip of EPDM engineered for that movement: it compresses, recovers and keeps the line closed.\u003c\/p\u003e\n\u003cp style=\"line-height:1.8;margin-bottom:18px;\"\u003eEPDM is the same elastomer used for automotive weather seals and flat-roof membranes, chosen because it tolerates ultraviolet exposure, ozone, and the freeze-thaw cycle without hardening into a brittle line that cracks in year three. The strip is produced in 5 and 10 metre lengths with a bottom width of 5, 6 or 7 mm, sized for the gap tolerances found on aluminium bridge, door and window profiles.\u003c\/p\u003e\n\u003cp style=\"line-height:1.8;margin-bottom:18px;\"\u003eInstallation follows the frame, not the wall. The strip seats into the profile channel, presses flat against the mating surface, and holds its shape under compression without needing adhesive to stay in place. That detail is what allows a repair to be done on a Tuesday afternoon without shutting a window for a curing period.\u003c\/p\u003e\n\u003cp style=\"line-height:1.8;margin-bottom:18px;\"\u003eThe economics are quiet but real: a sealed joint means the heating or cooling you paid for stays inside, and the aluminium profile stops collecting condensation on the cold side. For a glazed facade or a run of bridge windows, the strip is the least expensive part of the assembly and the one that decides how the assembly performs.\u003c\/p\u003e\n\u003cp style=\"line-height:1.8;font-style:italic;font-weight:500;margin-top:6px;\"\u003eSeal the joint and the whole structure stops arguing with the weather.\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin:24px 0;border:0;border-top:1px solid #eee;\"\u003e\u003cdiv class=\"product-features\" style=\"margin-top:28px;\"\u003e\n\u003ch3 style=\"font-size:20px;font-weight:600;letter-spacing:.02em;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ EPDM elastomer resists UV, ozone and freeze-thaw cycling\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ Available in 5 and 10 metre continuous lengths\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ Bottom widths of 5, 6 and 7 mm match common profile channels\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ Compression-recovery behaviour follows structural movement\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ Seats into aluminium bridge, door and window profiles\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ Holds position under compression without adhesive curing time\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e✦ Reduces condensation on the cold side of aluminium frames\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-specs\" style=\"margin-top:28px;\"\u003e\n\u003ch3 style=\"font-size:20px;font-weight:600;letter-spacing:.02em;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;margin:0;\"\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e EPDM rubber\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 0011\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eLength options:\u003c\/strong\u003e 5 m and 10 m\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eBottom width options:\u003c\/strong\u003e 4.2 mm, 5 mm, 6 mm, 7 mm\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Expansion and sealing strip\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Aluminium bridge, door and window profiles\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eWeather resistance:\u003c\/strong\u003e UV, ozone, freeze-thaw\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eCustomisation:\u003c\/strong\u003e Cut lengths available\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli style=\"padding:10px 0;border-bottom:1px solid #eee;\"\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Mainland China\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-applications\" style=\"margin-top:28px;\"\u003e\n\u003ch3 style=\"font-size:20px;font-weight:600;letter-spacing:.02em;\"\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp style=\"line-height:1.75;\"\u003eGlazed facades and curtain wall runs where aluminium profiles expand at a different rate to the structure.
