Main data

How to use it (step by step installation)

1. Structure: prepare the metal framework (or check the masonry cavity). Check for flatness and verticality.
2. Cut: unroll 76R and cut a strip slightly higher than the available space (1–2 cm) with a cutter for a precise fit.there>
3. Insertion: place the roll without compressing excessively; avoids gaps along studs and joints.
4. Junctions: bring the edges together without overlappingIn false ceilings, use suitable fixings and provide for counter camber.
5. Closure: fit the sheets (plasterboard or equivalent) as per the system, tape and fill.

Practical advice

• Calculate the m2 and add +5-8% for scraps.
• Wear PPE (gloves, glasses) and work in a ventilated environment.
• Store rolls indoors and flat, away from moisture and direct heat.
