Fire protection roof screen for flat-roof membranes

Fire Protection Roof Screen: TexTherm M0 by Passitex for Flat-Roof Membranes

15 October 2026

Flat roofs carry more than waterproofing. They carry rooflights, chimneys, firewall junctions and plant equipment. Each of these details is a place where fire from outside can reach the roof surface. Synthetic membranes keep water out, but they are not designed to be non-combustible.

A fire protection roof screen closes that gap. TexTherm M0 from Passitex is a fireproof glass-fabric screen made for PVC, TPO and EPDM membranes. This article covers what it is, where it fits and how it installs.

Why Flat Roofs Need Waterproofing Membrane Protection

Membranes are chosen for flexibility, durability and watertightness. Fire behavior is a separate question, and specifiers have to address it separately.

Certain roof zones call for a non-combustible layer:

Both sides of firewalls, where fire must not travel across the roof
The base of upstands, where the membrane turns up a wall
Rooflights and chimney surrounds, close to heat and sparks
Areas exposed to cigarette butts or hot work debris

For architects, BET firms and facility managers, a screen in these zones is targeted waterproofing membrane protection. It adds fire performance exactly where the risk sits, without changing the rest of the roof build-up.

What Is TexTherm M0? A Non-Combustible Screen M0 for Roofs

TexTherm M0 is a fireproof glass-fabric screen designed to sit on flat-roof waterproofing membranes. It is made by Passitex, a French manufacturer of passive fire protection systems. The principle is simple: use materials that don’t burn.

Property	Value
Fire classification	M0 / Euroclass A2-s1, d0
Thickness	0.4 mm
Weight	450 g/m²
Color	Light grey (custom colors on request)
Membranes	PVC, TPO, EPDM

What does Euroclass A2-s1, d0 mean? A2 means non-combustible. The s1 rating means very limited smoke production. The d0 rating means no flaming droplets. M0 is the older French term, and it still appears in many specifications.

Key Benefits of a Non-Combustible Screen M0

Non-combustible: Euroclass A2-s1, d0 classification
UV-proof: suited to long exposure on open roofs
Weatherproof: built for outdoor conditions
Halogen-free: no halogenated materials
Lightweight: 450 g/m², easy to carry and cut on the roof
Custom colors: available on request

Together, these make TexTherm M0 a practical layer of passive fire protection. It needs no power or detection system to work. The material itself is the protection.

Where TexTherm M0 Is Used

Flat roofs with PVC, TPO or EPDM waterproofing membranes
Firewall junctions and upstands
Rooflight and chimney surrounds
Industrial and commercial buildings, warehouses and logistics sites
New builds and roof renovations

The screen protects the membrane surface. It does not replace the waterproofing layer beneath it.

Installation and Site Delivery

TexTherm M0 is delivered in 1 x 50 m rolls, shipped directly to site, so crews have material when they need it.

Installation is straightforward:

Clean the membrane surface.
Position the screen.
Glue it directly onto the membrane.
Check coverage at edges and details.

The lightweight rolls mean fewer tools and less time on the roof. Always follow Passitex’s installation instructions for your membrane type.
