Complete Range for Industrial, Commercial, and Agricultural Applications
The roof is where an industrial building loses or gains the most energy. Solar radiation on a bare metal sheet roof drives internal temperatures that can exceed 50°C in Indian summer conditions — a thermal load that overwhelms ventilation systems and makes occupied factory or warehouse spaces practically unusable without significant air conditioning investment. A PUF roofing panel changes this equation at the structural level: the insulated composite construction intercepts solar heat gain before it enters the building, reducing internal temperatures and slashing the cooling energy demand.
Horizon Roofing Distributors supplies PUF roofing panels manufactured by Mount Roofing & Structures. These are composite roof panels — two steel skins with a rigid Polyurethane Foam core — designed and profiled specifically for roof installation. The roof-specific profile creates the drainage geometry and structural rib depth that a flat wall panel does not have. Mount manufactures PUF roofing panels with profiled external steel skins in standard roofing profiles, available from 30mm to 200mm thickness for applications ranging from standard industrial warehousing to deep freeze cold storage roofs.
The thermal performance case for PUF roofing panels in Indian construction is compelling. ECBC 2017 requires a roof U-value of 0.440 W/m²K or better in warm and humid climate zones. A 60mm Mount PUF roofing panel achieves U = 0.35 W/m²K — exceeding the code requirement without additional insulation. For a factory in Maharashtra or Gujarat, this single specification choice can reduce cooling load by 35–50 tonnes of refrigeration on a 10,000 sq metre building footprint, with a corresponding reduction in HVAC capital cost.

PUF roofing panels from Mount are used across the following roof types and building categories:
Our selection of Mount Roofing & Structures as the sole supplier for this platform was driven by roofing-specific performance considerations. A PUF roof panel is exposed to UV radiation, thermal cycling, wind uplift, and direct rainfall — the performance of the steel facing and the bond between the facing and the foam core determines the panel's durability across a 20–25 year service life.
Mount's roof panel facings use PPGI steel with polyester or PVDF coating applied at the coil processing stage — not painted after forming. This means the coating adhesion is to the flat coil surface, not to a formed panel, which is the coating application standard that produces the best long-term adhesion. For coastal and high-humidity environments across Tamil Nadu's industrial coastline or Gujarat's industrial zones, Mount offers PVDF-coated facings with extended UV and corrosion resistance.
The fastener system for Mount PUF roof panels uses HEX-head self-drilling screws with EPDM washers — supplied by Mount as part of their Mount Industrial Roofing Solutions package. The fastener specification includes torque requirements (8–10 Nm for standard 6.3mm screws) and installation speed recommendations that are critical to maintaining the EPDM washer seal over the panel's service life. We provide this installation documentation to all buyers as a standard part of supply.
