12mm Expansion Cork Sheets

Natural cork expansion sheets designed for timber floor installation and construction joints. These 12mm-thick sheets (915 × 610mm) compress to accommodate wood movement caused by temperature and humidity changes. Cut strips to match your floor thickness and install between surfaces or around perimeters. Each sheet yields approximately 20–25 linear metres. Apply adhesive, sand flush, and finish to match your flooring. Essential for preventing gaps and buckling in timber installations.
