As one of NI's leading timber merchants, MacBlair takes the quality and sustainability of the timber we sell very seriously with all of our timber and plywood being FSC and PEFC Chain of Custody certified. We stock a vast range of timbers in various lengths, such as rough sawn timber for joists, rafters and studwork. We also keep range of treated structural grade timber, fencing and decking for timber that will be exposed to moisture and the elements. For internal work such as door framing and door stop we keep Planed All Round timber (PAR). This has been run through a planer to give it a smooth, clean edge and is ready to be primed and painted. Sheet materials such as plywood, MDF and OSB are also stocked, available in various thicknesses.
