PEB Roofing & Wall Cladding

What we deliver

Roof and wall sheeting, insulated sandwich panels, skylights, ventilators, flashings and gutters for PEB and industrial buildings — the envelope that decides how hot the building runs and whether it stays dry.

On an industrial building the envelope is most of the building's surface area, and the roof takes the most sun. Its specification sets the inside temperature, the lighting load and the running cost for as long as the building stands.

Scope of works

Element	What we deliver
Roof sheeting	Single-skin or insulated panel, fixed to purlins
Wall cladding	Sheeting or insulated panel on girts
Insulation	PIR or rock wool panels where specified
Daylighting	Polycarbonate or FRP skylight sheets
Ventilation	Turbo ventilators, ridge vents, louvres
Rainwater	Gutters, downpipes, valley details
Flashings	Ridges, eaves, corners, penetrations

Where projects go wrong

• Fastener spacing uniform across the roof. Edges and corners need closer spacing for wind uplift.
• Laps not sealed or too short. The most common cause of industrial roof leaks.
• Penetrations poorly flashed. Every ventilator and pipe is a potential leak.
• Skylights without insulation strategy. They bring daylight and heat.
• Gutters undersized. A large roof sheds a great deal of water quickly.
