The total replacement of the flat roof covering on a residential apartment building in North London presents a prime example of why leading waterproofing systems manufacturers are specifying the use of Magply boards as a decking which offers critical fire resistance as well as good load-carrying and weathering capabilities.

The property involved is Block 6 at Tiltman Place in the Finsbury Park district where water ingress through the original felt roof covering had caused the plywood decking to deteriorate badly while, along with other damage, the insulation had become saturated: necessitating total strip back and replacement.

The managing surveyors for the five storey property duly decided to appoint Detailed Waterproofing Ltd. as a well-experienced roof specialist, while the supplier of the roofing system specified the use of high performance Magply boards to provide a sound new decking across the retained metal frame structure.

The build-up features the use of 20mm Magply Al boards, proteus self-adhesive vci, cut to falls insulation, Proteus self-adhesive carrier membrane, then followed by a cold applied Proteus ‘Pro-System’ waterproofing membrane.

The Contract Manager for Detailed Waterproofing, Jamie Tarry, commented “We hadn’t previously used Magply before it was specified to us here as part of the new built-up system on Tiltman Place, but it has proved very easy to handle in terms of cutting and fixing.  The job went well and we finished on schedule.”

Backed by a number of industry recognised standards Magply provides an ideal alternative to conventional plywood or OSB products.  Additionally, the unique production process keeps the chloride content to just 0.01^%, enhancing both stability and long-term durability.  The different thicknesses of panel are also widely used for flooring and pitched roof installations; as well as being approved by many different manufacturers of render finishes.
