A new four-chamber co-extruded reversible sash profile from LB Plastics has been launched to provide thermal efficiency and a eurogroove for simpler hardware installation. It has a bevel feature for a 'softer' line and a matching weldable dummy transom to give a sliding sash appearance. Accredited to BS7412 and BS7950, the Sheerframe profile can be used on newbuild and social housing refurbishment projects.
