Glennon Brothers has been manufacturing high quality timber products since 1913. Through plants in Longford and Fermoy, and Windymains and Troon  in Scotland, we supply both the Irish and UK markets with products for the construction, pallet wood and fencing industries.

Our product range includes:

Timber processing produces residual by-products such as woodchip, sawdust, bark and shavings.

  • Woodchip is predominantly used in the manufacture of MDF board
  • Sawdust is used to power the kilns for drying the timber and is also used in the manufacture of chipboard and for animal bedding
  • Bark is further processed and used as garden mulch
  • Wood shavings are also a very popular bedding solution for the horse and poultry industries

Glennon Brothers also design, manufacture and supply timber frame homes and engineered roof trusses through Dempsey Timber Engineering in Arklow and Alexanders Timber Design in Troon, Scotland.

Dempsey’s are approved and monitored by the National Standards Authority of Ireland (NSAI), while Alexander’s are members of the Q mark plus scheme in the UK which is accredited and regulated by BM Trada
