Pre-tested Fire Door Blanks

We provide highly efficient fit for purpose doors. The product is quality tested on various parameters to ensure its high performance and durability. Different tests done on the product includes:
Mechanical Testing: The tests were conducted in accordance with British Standard Draft for Development DD171:1987,BS EN 1191:2000. Halspan Doors in full door set mode have been tested in single action single, and double action single mode and achieved Severe Duty Grading.
SD-Severe Duty: Subject to frequent violent usage. Halspan achieved the highest grading in the British Standard of Mechanical Tests for "hinged or pivoted doors"-Severe Duty: Subject to frequent violent usage.
Acoustic Performance: The test has been conducted in accordance to BS EN ISO 141.3.1995, BS EN ISO 717.1.1997. Halspan cores has been extensively tested using various perimeter sealing options in single, double door configurations and also including glazing. Depending on the option chosen the acoustics performance ranges from 28dB and 35dB
Thickness: As a rule FD30 door leaves are nominally 45mm thick though some designs may have test evidence at lesser thickness. FD60 doors are usually 54mm in thickness but are also available in 45mm. Thicker door leaves will usually have a greater size envelope because:
a cThey have increased resistance to burn-through.
a cIf distortion does occur, through-gaps are less likely.
a cWider intumescent strips can be incorporated into the door/frame joint.
