Column & Beam Encasement

A high performance fire protection system to enclose structural I type columns and beams.

• Single and double plasterboard layer configurations
• Up to 120 minutes fire resistance achieved*
• Wide range of section factors covered

*Derived from an assessment based on the calculation method in accordance with equation 4.2.7 from BS EN 1993-1-2 to calculate the temperature rise of steel sections insulated by fire protection material and actual fire tests to BS 476-21:1987 carried out at UKAS accredited test Laboratories. Further validated by numerical validation method (FEA).BRE Documents P119630-1000 Issue 1 & P119630-1000 Issue1.1 apply.

Framework Installation

To be read with reference to BS 8000:8 2023 and in conjunction with full Speedline / Tradeline project specific documentation which is created and available on request.

Four-Sided Protection Frame Installation

AWL10B Metsec Drylining Steel Framing Clips are friction fitted on to the column / beam flanges at maximum 800mm centres.

WL507 Metsec Drylining Wall Liner Channel is located over the clips to encase the column /beam.

Metsec Drylining partition brace or flat strap is needed behind any horizontal join in the plasterboard.

Three-Sided Protection Frame Installation

SL06 Metsec Drylining angle is located to both sides of the wall / soffit and secured at maximum 600mm centres using suitable fixings

AWL10B Metsec Drylining Steel Framing Clips are friction fitted on to the column flanges at maximum 800mm centres.

WL507 Metsec Drylining Wall Liner Channel is located over the clips to encase the column.

Metsec Drylining partition brace or flat strap is needed behind any horizontal join in the plasterboard.

Plasterboard Installation

Single Layer

Plasterboard must be fixed at 300mm maximum centres within the body and perimeter of the board. FS24 is required behind all horizontal plasterboard joints.

Position drywall screws not less than 10mm from the paper bound edge of the plasterboard and 13mm from any cut edge. Ensure a minimum of 10mm penetration into the studwork.

Recess heads of drywall screws below surface of plasterboard but do not break paper or gypsum core.

Double Layer

Inner layer of plasterboard can be screw fixed at 600mm maximum centres within the body and perimeter of the board however the outer layer must be fixed at 300mm maximum centres within the body and perimeter.

The outer layer of plasterboard must be fixed with all joints staggered in relation to the inner layer. FS24 must be included behind any horizontal plasterboard joint in between the inner and outer plasterboard layer.

Position drywall screws not less than 10mm from the bound edge of the board and 13mm from any cut edge. Ensure a minimum of 10mm penetration into the studwork.

Recess heads of screws below surface of plasterboard but do not break paper or gypsum core.

The above is issued as a guide – full system specific documentation (dependent on required performance) is available on request.
