wHAT IS SEADEC MANUCHECK?

At Seadec, we take immense pride in presenting our 3rd party accredited certification for fire door sets. Backed by stringent third-party regulation and approval from industry-leading joineries and door manufacturers, our fire doors stand as a true testament to our unwavering commitment to quality and compliance.

It is imperative to acknowledge that “Seadec Manucheck” certification, with its rigorous and extensive regulatory oversight, instils utmost confidence and reliance in Seadec’s fire doors among architects, specifiers, joineries, and all esteemed members of the building industry.

WHAT IS REQUIRED UNDER REGULATIONS?

Under the technical guidance document Part B, Appendix B mandates strict requirements for complete fire door sets’ correct assembly and permanent identification. To comply with these regulations, each fire door set must bear crucial details, including the assembler’s name, date of supply, fire door classification number, and fire door rating.

These crucial pieces of information serve as a comprehensive record of the fire door’s specifications, ensuring that it meets the appropriate fire safety standards and can be relied upon to safeguard lives and property in the event of a fire. By adhering to these regulatory guidelines, stakeholders can ensure the utmost fire safety assurance and maintain full compliance with the necessary building regulations.

The elements of the audit

In order to provide the maximum confidence in your fire door set, Seadec have introduced a 3rd party accreditation scheme – Seadec Manucheck. This is to audit independently, the manufacturing process of door set manufacturers. There are 3 elements to the audit:

1. Manufacturing process

The joinery is audited to ensure that the manufacturing process is managed to a high standard and that work flows within the joinery are ideally suited for fire door set manufacturing.

2. Traceability

The fire door set assembler is required to show that all door set components, such as hinges, locks fire seals etc that have been used to make up fire door sets with Seadec doors, are compliant with our fire door certification documents.

3. Calibration

The door set manufacturer must show that during the production process a sample of manufactured door sets are tested for important details such as location of hinges, gaps between the door and door frame, to ensure that all door sets are being correctly manufactured.

technical informATION

Fire doors are crucial for passive fire protection in buildings like hospitals, schools and homes. Nowadays, there is a growing demand for high quality fire doors in apartments, duplexes, and three-story houses. Seadec strives to offer superior solutions by prioritizing fire protection, design and environmental management.

About EN 1634.1

Since 2019 and the impact caused by Brexit we have focused on upgrading our fire door certification from BS476.22 which was the older British standard to the new European standard EN 1634.1. EN 1634.1 as a fire test is more difficult to achieve. A combination of factors including more intensive exposure to heat, air pressure and a more accurate measurement of heat transfer through the door means that the EN 1634.1 test is a lot more onerous for a fire door to pass.

About EN 1634.3

There are areas within buildings where the fire doors also need to protect against the movement of smoke in the event of a fire. This is a separate test to a fire test and is certified under EN 1634.3. Doors located in areas such as apartment front entrances, riser doors, hallway doors & stairwell doors usually require smoke control. It is important that the fire doors used in these situations have certification available for fire (EN 1634.1, and smoke control EN 1634.3.)

Thresholds

Under EN 1634.1 certification thresholds should only be used under fire doors with a rating of 30 minutes or less. The correct threshold detail is shown below.

B = Timber threshold, minimum density must be 600kg/m3.
If alternative thresholds are to be used, they will need to be approved by the fire engineer before use.

Concealed door closers

At Seadec, we have tested our fire doors extensively with surface mounted door closers, and also concealed door closers. Our flush doors can be used with Astra, Assa Abloy and Rutland concealed door closers. For additional information on fitting and protecting with intumescent material, please refer to our fire door certification documents.

Structural Openings

It is important that the structural openings for fire door sets should be large enough to receive the fire door set correctly, and can be correctly fire stopped using an approved fire retardant product. A list of proposed structural opening sizes is shown below for our door sizes.

Fire Stopping

The gap between the structural opening and the back of the door frame must be kept as small as possible. It must be completed with fire stopping material. This helps to stop the spread of fire and smoke. Please refer to our fire certification documents to review what fire stopping materials are allowed with each door type. It is always a good idea to have this material approved by your fire engineer before installing. Installation should be by a properly trained individual.
