Challenges
Installing balustrades on parapet walls and flat roofs requires careful consideration to avoid compromising the waterproof membrane or GRP (glass-reinforced plastic) roof coverings. Traditional methods often risk puncturing these layers, leading to leaks, water ingress, and costly repairs. Key concerns included maintaining watertightness, transferring loads safely to the building structure, and ensuring long-term durability without ground penetration.
Solution: Dio-Met's Parapet Wall Glass Balustrade System
Our innovative, structurally sound system uses two substantial horizontal rails with clear glass infills, designed specifically for how to install balustrades on waterproof or GRP roof coverings. This approach avoids any membrane penetration by bolt-fixing through drain blocks or side mounts, allowing water to flow via integrated drainage channels (e.g., using sealants, butyl tape, or bituminous paint for seams). Loads are transferred directly to the building, not the ground, ensuring compliance and preventing pooling. The powder-coated steelwork offers a sleek, modern finish, while toughened glass panels maximize visibility.
As experts in architectural metalwork, we draw on extensive experience to provide solutions like vertical fixes (bolted to supporting walls) or ballasted systems for non-penetrative installs, ideal for EPDM, bituminous, or GRP roofs. All designs meet UKCA certification and British Standards for safety.
Benefits and Results
- Unobstructed Views and Elevated Design: The post-less glass allows seamless enjoyment of Chesterfield's rolling hills, perfect for morning coffee or evening relaxation.
- Enhanced Safety and Compliance: Robust construction withstands loads, with full UKCA certification ensuring building regulation adherence.
- Waterproof Integrity: No membrane punctures mean zero risk of leaks, extending roof lifespan.
- Aesthetic and Durable Finish: Powder-coated rails blend with new build architecture, using high-quality materials for minimal maintenance.
This project has elevated the living experience, adding value to the properties with safe, stylish outdoor spaces.
