Overview & History
Cladtech Associates Ltd (CTA) is a specialist independent curtain walling and cladding consultancy firm providing construction industry professionals, developers and contractors with technical advice on all matters concerning curtain walling, lightweight cladding, windows and glazing on commercial and large scale residential schemes. CTA has no affiliation with any trade organisation, company, firm or supplier to the industry and are therefore totally independent.

The practice was originally formed in 1975 between Norman Plough, who was an established window consultant and Russ Buczkowski based in Chicago. In 1985 Cladtech Associates was established by Stephen Green and Peter Plough and they expanded its UK and international activities considerably.

In December 2017 Cladtech Associates became a Limited company with Peter Plough, Simon Armstrong and Shaun Kelly as Directors. Lawrence Gray became a director in April 2019.
In 2022 Simon Armstrong and Peter Plough stepped down as directors and Shaun Kelly and Lawrence Gray became the two principal directors.Shaun Kelly holds a master’s degree in facade engineering and has worked in the industry throughout his adult life.
