PVC Roofing
Single-ply PVC and TPO/FPO roofing — lightweight membranes hot-air welded into one continuous skin over large roofs.
One System, Built to Work Together.
Single-ply roofing covers big areas fast: wide, light rolls fixed mechanically or ballasted, with every seam hot-air welded into homogeneous joints that can be tested seam by seam.
PVC and TPO/FPO membranes carry long exposed service lives with high reflectivity, making them the standard for commercial, industrial and logistics roofs worldwide.
- Commercial and industrial flat roofs
- Warehouses and logistics parks
- Metal-deck and lightweight roofs
- Re-roofing over existing build-ups
- High-reflectivity cool roofs
Layer by Layer.
- 01
Deck Preparation
Concrete or metal deck checked, cleaned and made ready for the build-up.
- 02
Thermal Insulation
Insulation boards fixed to the deck bring the roof to the required U-value.
- 03
Separation Layer
A fleece protects the membrane from the substrate and incompatible materials.
- 04
PVC / TPO Membrane
The single-ply membrane, mechanically fixed and hot-air welded at every seam.
- 05
Terminations & Trims
Perimeters, upstands and penetrations finished with coated metal profiles.
01Testable Welded Seams
Every hot-air weld can be probe-tested before handover — no hidden weak joints anywhere on the roof.
02Light on the Structure
Single-ply weighs a fraction of built-up systems, ideal for metal decks and long spans.
03Fast Coverage
Wide rolls and mechanical fixing close large roofs quickly, in more weather windows than torch systems.
04Long Exposed Life
UV-stable polymer membranes are engineered for decades of direct exposure.
Common questions about this system.
Where is the PVC Roofing system used?
It is typically used for commercial and industrial flat roofs, warehouses and logistics parks, metal-deck and lightweight roofs, re-roofing over existing build-ups and high-reflectivity cool roofs.
Which Insutech products are used for pvc roofing?
The recommended system is built with TPO/FPO Roofing Membrane, PVC SE — Exposed Roofing, PVC BAT — Basements and Insu Foam — full details for each are on the recommended products cards on this page.
How is the system installed?
The system is installed in 5 stages: deck Preparation, thermal Insulation, separation Layer, PVC / TPO Membrane and terminations & Trims. The system build-up section on this page illustrates the full sequence.
What are the main advantages of the pvc roofing system?
The key advantages are testable Welded Seams, light on the Structure and fast Coverage — each is explained in the Key Benefits section on this page.
