Using mesh reinforcement in external render

Rendering inappropriate surfaces

Renders are sometimes required to be applied to cover up bad construction practice and inappropriate surfaces

Remodelling facades

Changing the use of a building often requires physical changes to its external fenestration, completely reshaping its structure

Upgrading the thermal insulation of a building

Initially a choice needs to be made regarding where to position additional insulation in the structure

Upgrading non-traditional housing

Early non-traditional or system built housing wasn't built for the long-term and doesn't meet today's thermal standards

Insulating single-skin construction

Single-skin construction requires significant attention to detail at openings to avoid moisture tracking around seals and into the inner face
