MS Fire Retardant, from Delta Membranes


David J Symes from Delta Membrane Systems Limited discusses the versatility of Delta MS 500 Fire Retardant membranes when it comes future proofing construction

In an age where prevention to fire is rightly under scrutiny in the construction industry, thoughts should be given to specifying materials which have properties which not only reduce the risk to occupants’ safety, but also have a lesser reaction time in the event of fire.

Delta’s new innovative fire-retardant MS 500 membrane gives a unique opportunity to the structural waterproofing sector for Type C systems to be used in reducing the spread of fire or where installation has not previously been possible for fire safety reasons.

Delta’s new fire-retardant Type C Cavity Drainage System provides architectural freedom and allows systems to be used in not only deep basements but where national Building Regulations Euroclass B or C are required, meeting building requirements of today, but also that of tomorrow.

Delta MS 500 Fire offers a B-S2, d0 Euroclass fire rating (EN 13501-1:2018) whilst maintaining its strength, durability, functionality, and workability.

The first and most essential element of a Type C membrane is keeping structures dry. Water ingress will potentially result in a corrosive environment, with structures having a reduced life service. Delta MS 500 Fire Retardant has been manufactured using DELTASAFE, compared to the traditional MS 500 membranes.

In principle a Type C, cavity drain membrane system allows moisture or running water to travel behind the membrane within a controlled drainage system. A cavity drain system requires minimal preparation and disturbance to an existing substrate.

In terms of appearance, Delta MS 500 Fire Retardant has the same physical properties to MS 500, a membrane designed from High-Density Polyethylene with 8mm stud.

Delta MS 500 fire retardant enhances a structure’s fire performance. MS 500 fire-retardant not only slows down but will reduce the intensity of a fire, limiting damage to a build’s structure and its contents.
