FIRE RATED GLAZED DOOR INSTALLATION METHOD
Fire Rated Glazed Doors are transparent building elements that prevent the fire from spreading inside the building. They create safe escape corridors throughout their endurance period, allowing people to evacuate easily. It prevents the growth of possible material damage by trapping the fire in a compartment until the fire brigade intervenes in the fire. It has the comfort suitable for use in daily living areas. It offers freedom in architectural design. They are generally preferred in floor landings leading to the stairwell. Thus, the stairs have the feature of both escape stairs and maintain their features suitable for daily use. Since there is no need for a second fire escape, there is no loss of space. As a result of detailed projecting processes, the doors are produced and installed on the construction site.
One of the most important steps of the projecting process is designing the installation details of the Doors. Due to their high weight, they need to be produced in high quality and firmly connected in the structure for long-lasting use. The installation details including the door’s relation with the wall and floor are designed by Pentek. It is then presented to customers for reconciliation. After the approval, Pentek teams, who are experts in their field, produce the doors and install them on the construction site.
Pentek pays attention to some issues while designing the installation details.
Feature of Wall
Firstly, the wall on which the door will be installed must be fire-resistant.
Fire Rated Glazed Doors should be connected to a solid structural element in a way to transfer the load to carry the active leaf (dynamic load) due to their weight. As Pentek, our preference is to install on reinforced concrete walls and beam/lintel.
However, in different projects, different wall types that do not have the required structural features may be encountered. For example, aerated concrete and plasterboard walls. In these types of light walls, blind frames produced with hollow structural sections in the cross-section and wall thickness determined by Pentek are used. The blind frame is fixed by welding to 10 mm diameter rods placed at approximately 800 mm intervals at vertical on sidewalls. The Glass Fire Door is also attached to the blind frame with Hilti Hus S screws.
Dilatation Gap Between Wall and Door Case
Another issue we pay attention to is that there is a “dilatation gap” between the doorcase and the wall to tolerate thermal elongations. Since the thermal elongation in Fire Rated Glazed Doors will be higher due to the high temperatures that will occur during the fire, the expansion gap values are also higher than standard joinery. Pentek finds it appropriate approximately 15 mm dilatation gap. After the doorcase and leaf installation, dilatation gaps are filled with fire-resistant high-density mineral wool. Mineral wool is also isolated with mastics and protected from environmental effects. Finally, after the fire-rated glass installation and controls, the door becomes ready for use.
