Supplied as a 30m x 1m roll (30m²), it sits between the substrate and the tile bed to absorb lateral movement and stress, helping to stop cracks in the floor below from transferring through to your tiles. At just 0.7mm thick it adds less than 1mm to the floor build-up, making it a practical choice for professional tilers, bathroom fitters and builders working over timber floors, heated screeds and cracked subfloors.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-in-1 anti-crack and decoupling\u003c\/strong\u003e – accommodates lateral substrate movement and protects the finished tiling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimal height build-up (under 1mm)\u003c\/strong\u003e – no awkward thresholds or door trimming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUses less adhesive\u003c\/strong\u003e than traditional 'waffle'-type decoupling mats\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast-track installation\u003c\/strong\u003e – tile as soon as the bedding adhesive has set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrinted 50mm grid\u003c\/strong\u003e for quick, accurate measuring and cutting with scissors or a knife\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eIdeal with underfloor heating\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eSuitable for commercial and domestic projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eDuoMat 360 is designed for floors only and is ideal beneath ceramic, porcelain, large format and natural stone tiles.
