Part M of the Building Regulations in England, titled "Access to and Use of Buildings," sets out requirements for making buildings accessible to all, including people with disabilities. In regards to manifestations on glass, Part M mandates that large uninterrupted areas of transparent glazing, such as glass doors and windows, be clearly marked to prevent people from accidentally walking into them, especially those with visual impairments.
Key points regarding manifestations on glass under Part M include:
Contrast: Manifestations must provide a clear visual contrast with the background to make them easily distinguishable by people with visual impairments.
Location: Manifestations should be positioned at the correct height and location to ensure they are visible to all users, including those in wheelchairs or with mobility impairments.
Size and Pattern: Manifestations must cover a specified percentage of the glazing surface to ensure visibility and may consist of dots, lines, patterns, or other designs that meet the requirements.
Continuity: Manifestations should be continuous across the glazing to create a consistent visual barrier and prevent confusion.
Compliance: Window manifestations must comply with relevant British Standards and regulations to ensure they meet the necessary standards for accessibility and safety.
Part M of the Building Regulations aims to promote inclusivity and ensure that buildings are accessible and usable by everyone, regardless of their physical abilities. It's essential for building owners, designers, and contractors to adhere to these regulations to create environments that are welcoming and accommodating for all users.
