About Magma Firestop application to a thatched cottage

Magma Firestop® Thatch Protector (previously SG-2H)

This product is produced for external application on a thatched roof and is tested and used worldwide.

In the UK, Magma Firestop® has been tested to BS476 Part 3 and achieved a BA designation.  The ‘B’ is for fire penetration into the material and the ‘A’ rating is for spread of flame.  This gives peace of mind to homeowners and many insurers offer reduced premiums for treated roofs.  Some insurers insist on Magma Firestop® treatment the property has a woodburner or open fire.

Magma Industries guarantee a correct application for 3 years, though the product generally requires reapplication every 5 years.  Most insurers recommend 5 yearly.  Thatch roofs require external Magma Firestop® reapplication due to the wearing of the thatch material.

The best time to apply Magma Firestop® Thatch Protector is after a total rethatch of the roof or any good maintenance work e.g. a new ridge and coatwork brush-down/dress up.  Reapplication to such roofs after 5 years and 10 years is not unusual.

Magma Firestop® Thatch Protector has a weather-proofing element in its formulation, which is what makes it suitable for the external use.
