Fire Sprinkler Boxing – Flame Retardant

Our flame retardant sprinkler boxing (FRSB) is manufactured from 9mm thick Euroclass B compliant MDF material and is designed for use where a flame retardant boxing is required to cover fire sprinkler pipework in new or retro-fit installations.

Available in both two-sided ‘L’ shaped and three-sided ‘U’ shaped profiles, our FRSB products are also painted with a flame retardant BS EN Class B s1 d0 compliant coating for additional fire protection.

Available in a comprehensive range of profile sizes and in 2400mm lengths. The choice of dimension enables FR sprinkler boxings to conceal fire sprinkler pipework and fittings in a range of different pipework configurations.

The sizes provided in the table below are indicative ‘standard’ profile dimensions only, as all FR sprinkler boxings are manufactured and supplied to the exact sizes required for each project.

Installation is a simple and straightforward process that requires only two timber battens, which are fixed to the wall or floor, allowing the FR sprinkler boxings to be secured using screw fixings.

Cutting to length on site and drilling to accommodate fire sprinkler heads is also a simple ‘on-site’ procedure. Where running lengths are required, the ends are butted together and intumescent jointing mastic may also be required to maintain fire resistant performance.

A full range of dedicated fire sprinkler boxing accessories is available, which includes internal and external corners, joint covers and stop ends. These are manufactured from the same flame retardant Euroclass B compliant material as our FRSB products and are coated with BS EN Class B s1 d0 paint.

In addition to being flame retardant, all our FR sprinkler boxings are manufactured from moisture resistant FSC® certified MDF. By using materials from sustainable and managed sources our products are not only covered by Forest Stewardship Council certification, but they also help specifiers, contractors and buyers comply readily with their own sustainable procurement policies.
