Glennon Brothers, operating from two sites in Longford and Fermoy, supply FSC certified timber products to the construction, fencing, and pallet and packaging sectors. All our logs come from sustainably managed forests. Our timber is Kiln Dried and machine strength graded under EN14081 to strength class C16. Though our timber frame division Dempsey Timber Engineering, we supply roof trusses and timber frame homes. Roof trusses are manufactured to Eurocode 5 and our manufacturing process for timber frame homes is certified by the National Standards Authority of Ireland to IS0 440.

With timber processing facilities, in Longford and Fermoy in Ireland, and Windymains and Troon in Scotland, Glennon Brothers supply sawn timber products for the construction sector, pallet and packaging, fencing and residue sectors. Glennon Brothers offer a unique one-stop-shop solution for sawn softwood in Ireland and the UK and also manufacture timber frame homes and roof trusses through, Dempsey Timber Engineering, in Arklow, and Alexanders Timber Design, in Troon. The company also provides forestry management services and purchase logs from private growers, completing the manufacturing process from forest to front door.

Glennon Brothers are proud members of Guaranteed Irish. Guaranteed Irish is a not-for-profit business membership organisation representing businesses in Ireland since 1974.

Guaranteed Irish is the original symbol of provenance in business in Ireland. Our members span all sectors including pharmaceutical, healthcare, technology, construction, energy, professional services, tourism, food and drink, art and design, retail & more. We award the Guaranteed Irish symbol to indigenous and international companies operating in Ireland which provide quality jobs, support local communities and are committed to Irish provenance. When assessing an applicant for membership, we look at three core criteria; jobs, community & provenance.

Beginning as a campaign ran by the Irish Goods Council in December 1974, Guaranteed Irish became an independent non-profit organisation in 1984 and was launched by President Patrick Hillery. Over four decades, the Guaranteed Irish symbol has become one of the most recognised symbols in the country. In 2017, Guaranteed Irish was rebranded and relaunched by An Taoiseach, Mr. Enda Kenny, T.D., with the original logo from the campaign’s inception. Led by CEO, Brid O’Connell, and a new Board of Directors and team, the organisation repositioned by opening up membership to international companies operating in Ireland.

Our member companies now directly employ 120,000+ people in Ireland and generate a turnover of €11.2bn here. Globally, these companies generate a turnover of €29.7bn. Currently, 46% of the members export, primarily to the UK, US and mainland Europe.

With 1,900+ members and growing, we believe that we are #AllTogetherBetter.
