Delta Fire Retardant Cavity Drain System (Type C)

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 important 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 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.

Introducing MS 500 Fire Retardant Membrane

What happens during a fire?

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.

What is a Fire Retardant?

A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. The Delta Fire Retardant range has been manufactured with DELTASAFE, a new innovative fire-retardant property which enables our MS 500 membrane to achieve a Euroclass rating of B-S2, d0 in accordance with EN 13501-1:2018.

Fire retardant Type C Cavity Drainage Membranes can considerably improve the reaction to fire of normal Type C Cavity Drainage Membranes.

What is the Difference Between Fire Retardant and Flame Retardant?

Fire retardant and flame retardant both work to prevent fires, in occurrence of fires to stop the spread and help to reduce the amount of damage caused by flames. Both are invaluable to protecting homes and structures and provide extra time to for residents to safely evacuate a building if a fire does occur.
