NMG Construction LTD.

NMG Construction Ltd sought to develop a hybrid EPDM/ Aluminium roof valley flashing product that would mitigate water ingress into a roof structure.  Recycled lead is shown to perish over short lifespans as a result of inferior quality in its production. NGM set out to develop a product that will seek to mitigate negative aspects of lead use in roofing.

Company Overview

NMG Construction Ltd has over 25 years of experience as main contractors engaged in a variety of both domestic and commercial building projects with particular expertise in the application of EPDM (ethylene propylene diene monomer (M-class rubber) roofing membranes. 


Innovation Voucher Objectives

  • Develop a product capable of replacing expensive and labour intensive conventional lead flashing (code 4 and 5) applications.

  • Wind uplift, thermo shock analysis, peel adhesion and impact/ shear tests for the hybrid concept.

Degradation of Recycled Lead

Material Testing

"The assistance I received from the Innovation voucher stemmed originally from low energy passive construction training which I received at IT Sligo.  This led to a successful Innovation Voucher submission to realise the product performance of my concept.  Six months on and plans for a prototype flashing machine are being developed.  The speed of the progression has been extremely encouraging while I can focus on getting on with running the business.
