Made in the USA, this 54\" x 32\" sheet sits atop Dynamat Xtreme or other damping layers to improve cabin comfort, protect delicate surfaces from heat, and add an insulating layer that won’t promote rust or mildew.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Dynaliner reduce cabin heat and protect components?\u003c\/h3\u003e\n\u003cp\u003eDynaliner’s closed-cell rubber structure reflects and slows the transfer of heat through vehicle panels and fiberglass. Its nearly doubled thermal resistance compared with typical low-density insulators keeps engine bay, trunk and roof heat from reaching the cabin or audio components.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4\" thickness provides a solid thermal barrier without heavy bulk\u003c\/li\u003e\n  \u003cli\u003eClosed-cell material sheds water, preventing moisture buildup\u003c\/li\u003e\n  \u003cli\u003eUse over Dynamat Xtreme or bare metal for stacked thermal performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this sheet help cut road noise and improve sound quality?\u003c\/h3\u003e\n\u003cp\u003eWhile Dynaliner is primarily a thermal insulator, its dense closed-cell rubber also dampens airborne and impact noise when applied under carpet or inside enclosures.

The 1\/4\" sheet offers a middle ground—substantial thermal resistance and noise reduction without the bulk or weight of 1\/2\"—making it ideal for under-carpet use and many enclosure applications.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8\": best where space is limited but some insulation is needed\u003c\/li\u003e\n  \u003cli\u003e1\/4\": strong thermal and acoustic performance with manageable thickness\u003c\/li\u003e\n  \u003cli\u003e1\/2\": maximum insulation where space allows\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? If you’re a car enthusiast, custom builder, sound installer or DIYer looking to lower cabin temperatures, reduce unwanted noise, and protect electronics or enclosures, Dynaliner is built for your projects. It’s especially useful when you want a moisture-resistant insulator that complements existing Dynamat damping products or serves as a standalone thermal layer under carpet, in trunks, on roofs, and inside fiberglass speaker boxes.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can Dynaliner be used over existing Dynamat Xtreme?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—Dynaliner is designed to be layered on top of Dynamat Xtreme to boost thermal resistance and comfort.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will Dynaliner trap moisture and cause rust under carpets?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No—its closed-cell rubber does not hold water, helping prevent moisture buildup and rust concerns.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Dynamat","offers":[{"title":"Default Title","offer_id":48082374459550,"sku":"B000WQOR4C","price":132.43,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/dynamat-dynaliner-front-sheet.jpg?v=1785811119","url":"https:\/\/northtrailauto.ca\/products\/dynamat-dynaliner-32-x-54-1-4-sound-deadener-thermal-insulator-self-adhesive-12-sq-ft-sheet-black","provider":"North Trail Auto","version":"1.0","type":"link"}
