What Are PVC-UV Insulated Roof Panels?
Insulated conservatory roof panels use a sandwich panel structure:
- PVC-UV outer protective layers
- XPS insulation core (extruded polystyrene foam)
PVC sandwich panels combine rigid PVC outer skins with an insulating core, creating a durable yet lightweight construction material suitable for external building use.
ThermoPanels specifically use PVC-UV layers with an XPS insulation core, providing durability, weather resistance, and strong thermal efficiency for conservatory roof insulation.
XPS foam cores are widely used in construction sandwich panels because they are lightweight, closed-cell insulation materials that provide excellent thermal performance and help maintain stable indoor temperatures.
Why PVC-UV / XPS Panels Are Ideal for Conservatories
- Excellent thermal insulation performance
- UV and weather resistance
- Moisture resistance
- Lightweight but rigid construction
- Easy to cut and install
This combination helps reduce heat loss in winter and solar gain in summer, making conservatories usable year-round.
How to Measure Before Cutting Insulated Roof Panels
Accurate measurement is essential before cutting.
Step 1 – Measure Each Roof Section
Measure length and width of each roof panel area from outside the conservatory.
Step 2 – Check Panel Thickness
Measure the thickness of your existing polycarbonate or glass replacement panel.
This ensures your new insulated roof panels for conservatory will fit correctly into existing glazing bars.
If unsure, our team can guide you before ordering.
