METAL LATHING

Preface

Macro-Mesh metal lathing is manufactured to BS1369: Part 1: 1987 in a range of weights.

It provides an excellent key for finishing materials on masonry, ceilings, suspended ceilings and timber frame buildings. This material is designed mainly as a background plaster reinforcement to minimize cracking.

Plasterwork on metal lathing offers a smooth, hygienic, monolithic surface giving it complete access to decorating. It also provides sound insulation and fire protection.

Commercial applications include partitioning, suspended ceilings and encasement of steelwork.
