Alkali-resistant fibreglass connector with rigid pre-formed central segment and double-threaded ends. Suitable for the structural reinforcement of brickwork, arches and vaults in masonry, tuff and stone, in combination with ARMAGLASS STRUCTURA fibreglass mesh and mortars such as UNISAN, INTOSANA and the REPAR family. It is used as a conduit for connecting the two sides of structural plaster (with the “structural sandwich” technique).

ARMAGLASS CONNECTOR TWIN is mainly used in plastering reinforced with sandwich systems comprised of mortars and fibreglass mesh. The rigid central section is available in segments of different lengths (200, 300, 400, 500 or 600 mm), while the two threaded ends are fixed at 200 mm in length. The ends are thus able to be opened radially and form an anchorage area of 400 mm in diameter. This method of connecting the two sides of the structural sandwich requires low-invasive preparatory operations, being easy to carry out and consequently resulting in low installation costs.

The ARMAGLASS CONNECTOR TWIN is used to reinforce masonry, arches and vaults in brick, tuff and stone. It is used as a through-connection for joining two sides of a structural plastering (employing the “structural sandwich” technique).
Ensure that the substrate is robust and free from loose parts. With any existing deteriorated plaster, strip the surface until restoring the masonry. Create through-holes on the section to be reinforced, using a rotating drill bit or core drill. The diameter of the hole should be equal to that of the connector plus at least 6 mm. The number of pass-through connections is to be determined by the drafter (usually between 3 to 5 connections/m2). Do not use percussion tools for drilling through-holes. Once formed, proceed with a proper blowing and suction of the hole to eliminate any debris. Secure the connector with hydraulic lime-based grouts (such as our SANAFLUENS), cement-based grouts (like our GROUT CABLE) or with chemical anchors (such as our SYNTECH PROFIX). Wet the substrate and apply an initial coat of mortar by hand or with a plastering machine until reaching a thickness of about 1.5 centimetres. Be quite vigorous if working manually or – even better – with a plaster spray machine, leaving the surface of the mortar sufficiently rough, without any smoothing operations, to facilitate the adhesion of the subsequent layer. Place the primed alkaline-resistant fibreglass mesh of the ARMAGLASS line (see the technical data sheet of the chosen product), placing it on the still-fresh mortar by passing the connector between the bars of the mesh and opening the ends of the same in accordance with a radial distribution. Finish with the application of a second coat of mortar at a thickness of about 1.5 centimetres. The temperature of the substrate must be between +5° C and +35° C. Do not apply at temperatures of around 0° C.
