Benefits of ProDeck Composite Bullnose Decking
As a capped composite decking board, these bullnose boards deliver strength and UV resistance. Their protective outer layer safeguards against moisture, mould, mildew, and rot, offering increased longevity over composite decking and timber.
ProDeck Bullnose Boards require minimal upkeep, eliminating the need for staining, sealing, or painting - saving both time and costs. The narrow groove surface improves slip resistance, and with a choice of seven colours available, these boards enable you to complete your ProDeck decking space to a high standard.
Built to withstand harsh conditions, ProDeck resists rain, snow, and extreme temperatures, ensuring durability across all climates. The splinter-free surface also enhances safety underfoot, making it a more comfortable and secure alternative to traditional timber decking.
Each board is manufactured with a robust honeycomb core composed of 60% FSC® certified recycled hardwood fibres and 40% recycled plastics, ensuring sustainability while reducing the need for frequent replacements.
Cladco ProDeck composite bullnose boards come with an extended 20-year warranty when installed with our recycled plastic joists. Please refer to our terms and conditions for further details.
