Berna 20mm Collection

The 20mm thickness of the Berna tiles is specifically designed for external use, giving them the strength and durability to withstand outdoor foot traffic, furniture loads, and the stresses of the UK climate. This extra thickness also makes them suitable for dry-lay and pedestal installations where tiles are not fully bedded in adhesive, as the added bulk provides the necessary structural stability.

Yes, the 20mm format of the Berna tiles makes them well suited to dry-lay installation methods, including pedestal systems used for raised terraces and roof gardens. This installation method can be quicker and allows for adjustment or access beneath the tiles if needed. Always ensure your chosen pedestal system is rated to handle the weight of 20mm porcelain tiles.

20mm porcelain tiles are significantly heavier than standard indoor tiles, so it is important to plan for this during both delivery and installation. We recommend having help available when unloading and moving packs, and storing them on a firm, level surface to avoid tipping. Delivery details including pallet weights are provided at checkout so you can prepare accordingly.

Yes, the Berna 20mm tiles are made from porcelain with a very low water absorption rate, making them frost resistant and fully suited to outdoor use throughout the year in the UK. They will not crack, warp, or deteriorate when exposed to repeated freeze-thaw cycles, giving you a long-lasting and low-maintenance patio surface.

As part of the outdoor porcelain patio tile range, the Berna 20mm Collection is designed with external safety in mind and features a textured surface to provide reliable grip underfoot in wet conditions. Please refer to the individual product listing for the specific R-rating of your chosen Berna tile, which will help you confirm suitability for areas such as pool surrounds or shaded, damp patios.
