What are roof sandwich panels used for?
What are roof sandwich panels used for? Roof sandwich panels form the insulated roof covering on industrial, commercial and agricultural buildings, combining an outer weatherproof skin, an insulating core and an inner lining in one fitted panel. They're commonly used on warehouses, factories and similar large-span buildings.
What is the difference between glass wool, rock wool and PU/PIR roof panels?
Glass wool roof panels use a fibreglass-based insulating core, rock wool roof panels use a mineral wool core, and PU/PIR roof panels use a rigid polyurethane or polyisocyanurate foam core. Each material suits different project requirements, so the right choice depends on your building's specification.
Are roof sandwich panels insulated?
Yes, roof sandwich panels are insulated by design, with the core material sandwiched between the outer and inner metal skins providing the thermal performance of the roof. The level of insulation performance depends on the specific core type selected for the project.
Can roof sandwich panels be used on industrial and agricultural buildings?
Roof sandwich panels are widely specified for industrial, agricultural and commercial roofing, including warehouses, factories and farm buildings, wherever a fast-fit insulated roof is needed. They're fitted directly onto the building's structural roof frame.
How do I choose the right roof panel core material?
The right core glass wool, rock wool or PU/PIR depends on the insulation and application requirements of your specific roof build. Contact our team with your project details and we'll help you confirm the most suitable option.
Do roof sandwich panels need additional flashing and accessories?
Yes, roof sandwich panel installations typically need supporting flashings, trims and fixings to properly seal joints, corners and edges. See our Flashing & Accessories range for the trims, screws and flashings used alongside roof panel installations.
Are roof sandwich panels suitable for both new builds and refurbishments?
Roof sandwich panels can be used on new-build roofing projects and, depending on the existing structure, in some refurbishment applications where the roof is being re-covered. Speak to our team about your specific project to confirm suitability.
What is the benefit of a sandwich panel roof compared to a traditional built-up roof?
A sandwich panel roof combines the outer weatherproofing, insulation and inner lining into a single factory-made component, which can simplify and speed up installation compared with building up separate roofing layers on site. This makes them a common choice for large industrial and commercial roof areas.
