The world’s only dual-purpose permanent chemical impregnation process for thatched roofs.
Micon Thatchbor is an aqueous treatment combining phosphate-based fire retardants and borate preservatives to deliver permanent, broad-spectrum defence against fire and biological attack.
Through a single pressure-impregnation process, Thatchbor penetrates the natural wax barrier to bond deep within each grass strand, ensuring lasting safety for your entire thatched roof.
Thatchbor reaches the heart of every stem for total protection. For complete building safety, pair Thatchbor with Flambor, our timber treatment, forming the ideal duo to safeguard both thatch and supporting structures from a multitude of dangers which can affect your thatched roof.





Thatchbor is tested to the stringent UNE-ENV1187:2003/A1:2007 and ASTM E-108 test protocol encompassing Spread of Flame, Burning Brand and Intermittent Flame testing.
