Insulated roofing panels put insulation and weatherproofing into a single interlocking sheet, so a factory or warehouse roof goes on fast and stays cooler inside. Rinac makes two roofing systems: InstaRoof, a fixed 30 or 50 mm interlocking panel, and CoolTop, a custom-thickness system up to 200 mm for demanding thermal loads.
Thermal performance depends on the selected core, thickness, joint, facing, climate and complete roof assembly. RINAC can provide the appropriate product data and project-specific thermal selection for InstaRoof or CoolTop.

Where Insulated Roofing Is Used
Applications across industry
Warehouses
Cooler, weather-tight roofs over large storage footprints, reducing heat gain on stored goods.
Factories & Plants
Insulated roofing that keeps production floors more comfortable and cuts cooling load.
Poultry & Livestock Sheds
Roof panels that moderate interior temperature and dampen rain noise in agri buildings.
Commercial Buildings
Clean, durable insulated roofs for commercial and institutional structures.
Cold Chain Facilities
Roofing over cold stores and processing plants where thermal control is critical.
Prefabricated Buildings
Fast-install roof systems for modular and prefabricated site buildings.
FAQ
Frequently asked questions
What are insulated roofing panels?
They are sandwich panels made for roofs: an insulating PUF or PIR core between a weatherproof top skin and an inner facing. One panel provides structure, insulation and a finished roof surface, installed as interlocking or overlapping sheets. Rinac offers InstaRoof and CoolTop.
How much heat do Rinac roofing panels block?
There is no single temperature-reduction figure that applies to every roof. Performance depends on the complete assembly, panel core and thickness, building use, ventilation and local climate. Ask RINAC for a project-specific thermal selection.
What is the difference between InstaRoof and CoolTop?
InstaRoof is a fixed 30 or 50 mm interlocking panel with a Galvalume facing and 1085 mm cover width. CoolTop is a custom-thickness system from 50 to 200 mm, with single panels up to 14,500 mm and a choice of facings, for higher thermal demands.
What thickness of roofing panel should I use?
Thickness must be selected against the product system, span, climate, interior condition and thermal requirement. RINAC publishes named InstaRoof and CoolTop configurations and can provide the current data sheet and project-specific selection.
Are Rinac roofing panels corrosion resistant?
InstaRoof product literature specifies a pre-painted Galvalume AZ150 external sheet. CoolTop offers project-selected metal facings. Confirm coating, substrate and environmental suitability for the site before specification.
