Insulation Products for Different Application Requirements

Air Bubble Insulation

A reflective insulation — layers of air-bubble film sandwiched between foil-faced outer layers.

Commonly considered for

Metal roof and wall underlayment, duct and pipe wrap, agricultural shed roofing.

Worth knowing

Works differently from bulk insulation: it targets radiant heat via a low-emittance foil surface, and only performs as intended when installed facing an open air gap.

XLPE Foam Insulation

A closed-cell, cross-linked polyethylene foam — sold as sheet, roll, or pre-formed pipe sections.

Commonly considered for

HVAC ductwork, chilled-water and refrigerant pipework, condensation-control applications.

Worth knowing

The closed-cell structure strongly resists moisture and water-vapour ingress, often without needing a separate vapour barrier.

Glass Wool Insulation

Fibers drawn from molten glass, bonded into blankets, rolls, batts, or boards.

Commonly considered for

PEB and metal-roof under-deck insulation, warehouse roof and wall insulation, HVAC duct wrap.

Worth knowing

Lightweight and cost-effective bulk insulation with good general-purpose thermal and acoustic performance — though it loses much of its value if compressed or wet.

Rock Wool Insulation

Fibers spun from molten basalt and/or slag, bonded into blankets, mattresses, or rigid boards.

Commonly considered for

High-temperature industrial process and equipment insulation, fire-rated partitions, acoustic insulation.

Worth knowing

Higher maximum service temperature and generally better fire performance than glass wool — it's non-combustible and doesn't melt or drip.
