Tongued & Grooved

Tongued & grooved boards deliver a seamless, interlocking finish that's become the go-to choice for professional cladding applications across Ireland. The precision-machined tongue and groove joint creates tight, weather-resistant connections that improve structural integrity whilst allowing for natural timber movement throughout the seasons.

Our Tongued & Grooved Cladding Selection

McMahons stocks a carefully curated range of T&G profiles to suit diverse project requirements:

• Softwood T&G boards: cost-effective solutions for garden buildings, sheds, and agricultural structures where durability meets value
• Treated T&G cladding: pressure-treated options offering enhanced rot and insect resistance for exposed exterior applications
• V-jointed profiles: creating distinctive shadow lines that add visual depth to both interior panelling and exterior facades
• Heavy-duty sections: thicker boards engineered for high-traffic commercial builds and demanding agricultural environments
• Various widths and lengths: flexible sizing to minimise waste and match your project specifications precisely

For alternative cladding styles, explore our complete Timber Cladding collection, including traditional Shiplap profiles that offer a different aesthetic finish.

Consider your project's exposure levels when selecting boards. Sheltered applications may suit untreated softwood, whilst coastal or ground-level installations benefit from treated timber or naturally durable species. Board thickness should reflect structural demands: lightweight garden rooms require less robust sections than exposed agricultural buildings facing harsh weather conditions.
