A1 Masonry Stone Wool Dash System

Masonry Stone Wool Dash System is a durable external wall insulation solution for masonry substrates, combining stone wool insulation with a robust dry dash finish. Designed for refurbishment, local authority, high-rise and residential EWI projects, the system provides a low-maintenance façade finish with strong weather resistance, impact performance and a wide choice of dash receiver and aggregate colour options.

This system is particularly suited to projects where long-term durability, thermal improvement and a traditional spar dash appearance are required. Wetherby’s stone wool dash build-up can be used across full elevations or combined with other façade finishes, including brick effect render, brick slip and silicone render, to support varied design requirements across masonry buildings.
