External Insulation & Weatherproofing
Weatherproof finishes that protect external pipework and ductwork insulation from moisture ingress and physical damage.
Quick answer
What is external insulation & weatherproofing?
External weatherproofing is the protective finish applied over insulation on outdoor pipework and ductwork. Systems include aluminium cladding, PIB, Proclad, Klasse Wraptec and Klasseclad — all selected to suit the project location, environment and specification.
What's included
- Aluminium cladding to pipework and ductwork
- PIB (Polyisobutylene) weatherproofing
- Proclad systems
- Klasse Wraptec
- Klasseclad
- Weatherproof jacketing on bends, valves and tees
- Mechanical protection for high-traffic areas
Typical applications
- · Rooftop pipework and ductwork
- · Plant deck installations
- · External plant rooms and energy centres
- · Industrial process pipework
- · Tank and vessel insulation finishes
Why this matters
External insulation is exposed to weather, UV and mechanical damage. A correctly installed weatherproof finish keeps the insulation dry, maintains its thermal performance and extends the life of the system underneath.
Materials & systems
Systems used include aluminium cladding, PIB, Proclad, Klasse Wraptec and Klasseclad. We select the system to match the project specification and the environment.
Frequently asked questions
- What external weatherproofing systems are available?
- Aluminium cladding, PIB, Proclad, Klasse Wraptec and Klasseclad are all commonly specified. Each offers different aesthetic, durability and cost characteristics — selection follows the project specification.
- Why does external insulation fail?
- Most failures are caused by moisture ingress through poor weatherproofing detailing, damaged jacketing or unsealed terminations. A properly installed finish prevents this.
