Timber is a core construction material used across structural, joinery and finishing applications in residential, commercial and agricultural building projects throughout Ireland. It plays a critical role in framing, load support, internal fit-out and external construction, where strength, dimensional stability and suitability for purpose are essential. TJ O'Mahonys range covers rough timber for structural framing and loadbearing use, treated timber for external and ground-contact applications, and planed timber (PAO) for joinery, internal framing and finished carpentry work. Sheet materials such as MDF, plywood, OSB and melamine panels are widely used in flooring, wall linings, formwork, cabinetry and furniture manufacture, supporting consistent performance and efficient installation on site. Our range also includes hardwoods and hardboards for specialist applications, machined timber products such as skirting, architraves, door frames and window boards, and stair and rail components used in internal fit-out and access construction. Timber products are selected for strength, moisture performance and compatibility with standard construction and joinery methods, supporting compliant building practices and long-term durability. Used in new builds, extensions, refurbishments and fit-out projects, timber remains a versatile and essential material for builders, carpenters and joiners requiring reliable performance across a wide range of construction applications.
