Lawtech Ltd was appointed to carry out the external wall insulation, and façade finishes by Allenbuild.

The scheme was a mixed use development on the site of the former Hugh Myddelton School consisting of 32 dwellings for rent and shared ownership, together with commercial space and basement cycle storage. Lawtech Ltd’s primary remit was to supply and fix Wetherby Epsitec External Wall Insulation System, incorporating 110mm phenolic insulation and silicone ‘K’ 1.5mm textured finish, applied to SFS sheathed in 12mm Cement Particle board.

Below DPC, the installation of 120mm Extruded Polystyrene Insulation Board with Wetherby system was called for, and to shear walls at stair tower location, Wetherby EWIS including 220mm Expanded Polystyrene.

In addition Lawtech were asked to complete the entire façade. The finishes used were:

ALUMINIUM TRAYPANEL SYSTEM. This system is a drained and back-ventilated rainscreen façade. Air pressure in the cavity behind the panels generally equalises with pressure outside so that wind-driven rain tends not to enter the cavity. Any small quantity which does enter the cavity, drains down the back of the panels and exits in a managed fashion at the base of the façade.

ARGETON TERRACOTTA RAINSCREEN CLADDING. The system can be used in both new build and refurbishment in traditional rainscreen form installed to concrete or blockwork substrates or as part of a unitised curtain wall or composite panel construction.

SIBERIAN LARCH TIMBER CLADDING. The system was installed onto rails lapped to form the façade with certified sustainable timber.

Lawtech is one of the largest installers of external wall insulation systems across the UK with offices in Rochester and Glasgow. Lawtech is UKAS accredited to ISO 9001 & ISO 14001 and is an active member of both the NIA & INCA.
