Smoke Vent - Installation Guide

Safety Standards and CDM Compliance:
The Mardome Smoke Vent Rooflights are designed to meet Class B non-fragility according to ACR[M]001 standards when installed following the provided installation guide. While the rooflights are robust, it is important to avoid walking on them, as any foot traffic or significant impact, such as a person falling onto the rooflight, can lead to potential damage and may require full replacement for safety assurance.

Security Features:
The security of Mardome Smoke Vent Rooflights is enhanced by the unique design, which conceals all individual fixings beneath security caps, making them difficult to access or tamper with. The polycarbonate material used in the construction is highly impact-resistant, providing additional protection against breakage, which increases the security of the building where they are installed.

Fire Safety and Compliance:
Mardome Smoke Vent Rooflights comply with Building Regulations Approved Document B: Fire Safety and have been tested in accordance with EN 13501-1. These rooflights achieve a B-s1,d0 fire rating, which indicates minimal smoke production and no flaming droplets in a fire scenario. Additionally, they meet the requirements for a BROOF(t4) classification, allowing them to be used at any distance from boundaries without restrictions on external fire spread.

Internal Fire Spread Guidelines:

• Residential Buildings (Volume 1): Rooflights with a B-s3,d2 classification are suitable for small rooms up to 4m² and garages up to 40m².
• Non-residential Buildings (Volume 2): Rooflights can be installed in circulation areas, small rooms up to 30m², and larger spaces, depending on the building’s specifications.

External Fire Spread:
The BROOF(t4) classification enables Mardome Smoke Vent Rooflights to comply with external fire spread regulations, allowing for their installation regardless of the building’s proximity to boundaries.

However, it is important to note that these rooflights are not fire-resistant and are not appropriate for use in scenarios where BS 476 part 22 fire resistance performance is required.

The Mardome Smoke Vent Rooflights provide a reliable combination of safety and security, making them a suitable choice for both residential and commercial applications that require effective smoke control and fire safety features.
