DEVImat™ 150T

DEVImat™ 150T is a self-adhesive electric underfloor heating mat designed for indoor floor heating applications, particularly in renovation projects where low build-up height is required.
 
The heating mat features a 360° screened heating cable with FEP-insulated conductors and a red PVDF outer sheath (non-UV stable). Its round cable profile and low installation height of only 3.5 mm support installation beneath tiled floors and other suitable floor constructions.
The self-adhesive mesh helps position and secure the mat during installation, contributing to a straightforward installation process.
DEVImat™ 150T must be used together with a compatible thermostat. Temperature control helps protect the installation against overheating and enables heating operation according to user settings.
 
The cold lead is supplied as an installation cable with solid conductors, supporting efficient connection during installation. The visible connection point between cold lead and heating cable helps installers identify the transition section correctly.
Each heating cable undergoes quality control procedures, including testing of electrical resistance, high-voltage performance, and material parameters before leaving production.
 
DEVImat™ 150T is covered by the DEVIwarranty™. Warranty terms, conditions, and coverage should be verified according to the applicable market requirements.
 
The product is supported by an Environmental Product Declaration (EPD), providing independently verified information on the product's environmental impacts across defined life cycle stages.
