As building regulations increasingly prioritise energy efficiency, airtightness has become a critical requirement in modern construction.

SMARTPLY AIRTIGHT is specifically developed to support low air permeability in timber frame and offsite systems. Manufactured with enhanced vapour resistance and precision-engineered tolerances, it helps form a durable airtight layer within wall and roof constructions when correctly detailed and sealed.

SMARTPLY SURE STEP DB combines structural flooring performance with built-in vapour control, supporting airtightness at floor level while delivering a robust working platform during construction.

Together, these panels help reduce uncontrolled air leakage, improve thermal efficiency and contribute to the overall performance of the building envelope.

Timber construction plays an increasingly important role in delivering sustainable, low carbon buildings. As a wood-based structural panel, OSB supports the wider use of timber frame and engineered wood systems.

SMARTPLY OSB is manufactured from responsibly sourced, fast-growing timber species, maximising resource efficiency while delivering structural strength. The panel’s performance characteristics make it suitable for wall sheathing, roofing decks and flooring substrates within timber structures.

Building with timber supports reduced embodied carbon, faster construction programmes and precision offsite manufacturing. SMARTPLY OSB is developed to integrate seamlessly into these modern construction methods.

SMARTPLY OSB panels are engineered to deliver consistent structural performance across a range of load-bearing applications.

Advanced production technology ensures uniform strand distribution, consistent thickness and dependable strength characteristics. This reliability supports efficient installation on site and predictable performance over the lifetime of the building.

The SMARTPLY OSB range includes panels suitable for structural use in humid conditions, precision-engineered solutions for airtight construction and specialist grades developed to meet specific project requirements.
