Metal Roof Insulation Project – Raw Materials Warehouse H

EMC carried out rehabilitation and insulation works for the metal roof of Raw Materials Warehouse H in 10th of Ramadan City, for ARMA Chemicals, covering a total area of 12,000 m².

The works included treating corrosion, replacing damaged metal sheets, and preparing the roof before spray-applying Polyurethane Foam to form a continuous thermal insulation layer, followed by an acrylic protective coating for water, UV, and weather resistance.

Scope of Work

Inspection of the metal roof and identification of corroded and damaged areas.
Removal of deteriorated and loose existing insulation layers.
Cutting and replacement of severely damaged metal sheets.
Rust removal and treatment of affected metal sections.
Repair of joints, connections, fasteners, and roof openings.
Reinforcement of vulnerable areas and joints using fiberglass and suitable treatment materials.
High-pressure water cleaning of the entire roof surface.
Treatment of joints and fasteners and final surface preparation.
Spray application of Polyurethane Foam across the roof, joints, and connections.
Formation of a continuous thermal insulation layer.
Application of an acrylic protective coating over the Polyurethane Foam.
Treatment and coverage of areas surrounding roof ventilators.
Completion of protective works for roof edges and associated metal elements.
Final inspection and handover of the completed insulation system.

Case Study

The Challenge

The main challenge was the extensive deterioration across a large metal roof area, including widespread corrosion, deteriorated existing insulation, damaged openings and joints around metal sheets, fasteners, and roof ventilators, requiring comprehensive rehabilitation before insulation works could begin.

The Solution

Deteriorated insulation and damaged metal sections were removed, corrosion was treated, and affected sheets were replaced. Joints, fasteners, and vulnerable areas were then repaired and reinforced before the roof was thoroughly cleaned, followed by Polyurethane Foam application and an acrylic protective coating.

The Result

The 12,000 m² metal roof was rehabilitated and protected with an integrated insulation system, helping reduce heat transfer and water ingress while protecting the foam layer and treated roof against UV exposure and weather conditions.
