Roofing projects often include technical terms, abbreviations and product references that can be difficult to interpret without industry knowledge. This glossary explains commonly used terminology related to Protan roofing systems, materials and construction methods. The overview is designed to help professionals better understand specifications, product names and technical documentation used in modern roofing projects.
SE – Self-Extinguishing
A roofing membrane with self-extinguishing fire properties. For example, Protan SE 1.6 is a 1.6 mm thick membrane with these characteristics.
SE-B – SE Basta
A phthalate-free roofing membrane that complies with Swedish Basta environmental requirements and is specified in certain projects in Sweden.
EX – Fleece-Backed Membrane
An SE membrane with a thin fleece layer on the backside, typically used in adhered roofing systems.
G – Glass Fibre Reinforced
Indicates a membrane reinforced with glass fibre for improved dimensional stability.
BP – BlueProof
A roof-based stormwater attenuation system designed to temporarily store and control rainwater on the roof.
BPG – BlueProof Green
A BlueProof solution designed to support additional rooftop functions such as green roofs, terraces or similar installations.
SE-T+ – Titanium Plus
A variant of the SE roofing membrane with a coated surface that improves durability and surface performance.
PVC – Polyvinyl Chloride
One of the most widely used plastics globally. Many Protan membranes are produced using PVC-coated textiles, providing durability, flexibility and long service life.
MW – Mineral Wool
Mineral wool insulation commonly used in roofing systems for thermal insulation and fire resistance.
EPS – Expanded Polystyrene
Lightweight insulation material widely used in roofing constructions.
XPS – Extruded Polystyrene
A rigid insulation material with high compressive strength and low water absorption.
GPS – Graphite Polystyrene
A form of EPS insulation with added graphite that improves thermal performance.
Sedum
A type of succulent plant frequently used on green roofs. Sedum plants tolerate dry conditions while retaining significant amounts of water.
Extensive Green Roof
A lightweight green roof with a thin growing medium, typically using sedum vegetation.
Intensive Green Roof
A green roof with a deeper soil layer that allows for larger vegetation, such as shrubs, gardens or rooftop landscapes.
ATB – Asphalt Roofing Membrane
Also referred to as roofing felt or bitumen membrane.
BIM – Building Information Modeling
A digital representation of a building that enables all stakeholders in a project to access shared information throughout the building’s lifecycle. Many Protan products are available as BIM objects.
Geotextile
Also referred to as slip layer, fleece or protection layer. Used to separate materials and protect membranes in roofing constructions.
Membrane Protection
A protective layer placed above the primary waterproofing membrane to reduce mechanical wear. In some cases, membranes that do not meet exposed-roof quality requirements may be used for this purpose.
Prefab – Prefabricated
Factory-produced membrane details such as corners, drains and pipe penetrations, as well as prefabricated roofing membranes prepared for installation.
F91 – Light Grey
Colour code used for Protan SE roofing membranes in light grey, the most widely used variant.
F94 – Dark Grey
Colour code for Protan SE roofing membranes in dark grey.
