280 gram/square metre structural mesh made of alkali-resistant fibreglass, containing >16% zirconium dioxide, constructed in English-style lap primed with thermosetting polymer. Certified mesh to prevent slab detachment. Easy and quick application, simple to handle and to cut. Combines lightness and thinness with excellent mechanical characteristics in terms of the weft and warp. Resistant to atmospheric agents and aggressive environments, it confers durability to the composite systems in which it is used. Suitable for any substrate and perfectly compatible with both cement-based and lime-based mortars.

Ideal for any type of substrate. Particularly suited to preventing slab detachment in combination with special steel components, also together with mortars with a UNISAN hydraulic binder base, which increases the performance of the system by ensuring breathability and a dehumidifying effect.
1.1 m/m²: The sheets adjacent to the fibreglass mesh are to be overlapped along the edges by at least 10 centimetres.
ARMAGLASS STRUCTURA 250 is a mesh for the structural reinforcement and consolidation of masonry and vaulted structures. It is ideal for reinforcing plasters with anti-overturning function, for the reinforcement and distribution of shrinkage stresses on walkable or drainage screeds and concrete flooring. A certified mesh to prevent slab detachment in combination with special steel components (screws, dowels, flanges).
Application on masonry and vaults:
In the event that connectors are being used, proceed with creating holes of a suitable diameter, in accordance with the chosen connection system and arranged in line with the design instructions and with the selected connection system (ARMAGLASS CONNECTOR, ARMAGLASS CONNECTOR SINGLE, ARMAGLASS CONNECTOR TWIN). Secure the connectors with resin anchors (SYNTECH PROFIX) or hydraulic binder-based slurry (GROUT CABLE, SANAFLUENS). Apply an initial layer of mortar (see the technical data sheet of the selected product), positioning the ARMAGLASS STRUCTURA 250 mesh on the still-fresh mortar, taking care to ensure an overlap of at least 10 centimetres, before applying the second layer of mortar. Whilst the mortar is still fresh, lay the mesh sheeting, proceeding from top to bottom, and immersing with the help of a putty knife, being sure to overlap each segment by at least 10 centimetres and impeding the formation of bubbles and bends.
Application on screeds:
Apply an initial layer of screed (see the technical data sheet of the selected product), laying the ARMAGLASS STRUCTURA 250 mesh on the first layer of still-fresh screed, taking care to ensure an overlap of at least 10 centimetres, then applying the second layer of screed.
