Wooden balcony construction method Promenade Roof Excel
The only wooden balcony construction method that requires no maintenance.
The Promna Roof Excel, chosen by construction professionals, provides maintenance-free roof balconies for wooden structures. Wooden balconies, which cannot avoid deformation and swaying, generally require maintenance because the waterproof layer can break due to substrate deformation and external forces. However, the Promna Roof metal waterproofing method incorporates a multi-layer water-stopping device with excellent toughness (ductility), achieving zero leaks in hundreds of thousands of installations. It has gained immense trust from construction experts. The safe and comfortable wooden balcony space, free from concerns about waterproof layer breakage, sick house syndrome, and environmental pollution, is created by Promna Roof.
