Product Description

Product Description

Aluminium foil thermal insulation, also known as radiant barrier foil insulation, is a high-efficiency heat reflective building insulation material laminated with aluminium foil and base materials including air bubble, XPE/EPE foam, woven scrim or fiberglass cloth.

The aluminium foil surface can reflect over 97% radiant heat, effectively blocking heat transfer from sunlight, high-temperature roof and hot pipes. Different from traditional thermal cotton that only slows heat conduction, this foil insulation cuts radiant heat loss and heat gain simultaneously, greatly reducing indoor temperature fluctuation and cutting air conditioning & heating energy consumption.

Core Advantages of Bubble Aluminum Foil Insulation Film

Excellent Radiant Heat Reflection

The double-sided aluminum foil surface can reflect up to 97% radiant heat. It blocks high-temperature solar radiation from entering the room in summer and prevents indoor heat from escaping outdoors in winter, effectively reducing air-conditioning and heating energy consumption. Unlike traditional cotton insulation that only slows conductive heat transfer, it suppresses radiant heat loss from the source.

Dual Thermal Insulation Structure with Air Bubbles

Independent closed air bubbles are sandwiched between two layers of aluminum foil. Air is a natural low thermal conductivity medium, which hinders heat conduction and air convection. Combined with the reflective aluminum foil, it forms a dual heat insulation system for better temperature control.

Reliable Waterproof & Vapor Barrier Function

The dense aluminum foil layer completely isolates water vapor penetration. It avoids condensation, dampness and mildew on metal roofs, attics and warehouse walls, protecting building structures and stored goods from moisture damage. Lightweight, Flexible & Easy to Install

Soft and lightweight, it can be cut arbitrarily with ordinary scissors. No complicated construction equipment or professional skills are required. It can be fixed by staples, adhesive tapes or nails on roofs, walls and pipelines, greatly cutting construction labor costs.

Shock Absorption & Noise Reduction

Elastic bubble layers buffer the impact of raindrops, hail and external vibration on metal roofs. It lowers rain noise and outside noise transmission, integrating thermal insulation and sound insulation into one material.

Strong Weather Resistance & Long Service Life

Anti-oxidation, anti-ultraviolet and anti-corrosion composite structure. It will not crack or age quickly under long-term outdoor exposure, maintaining stable heat insulation performance year-round.

Safe, Non-toxic & Recyclable

Made of environmentally friendly PE bubble film and non-hazardous aluminum foil composite, no harmful volatile chemicals. The whole material is recyclable, safe for closed spaces such as houses and greenhouses.

Versatile Application Scenarios

Perfect for metal roofs, attics, garages, warehouses, sunrooms, greenhouses, RVs, containers and HVAC pipelines. Custom sizes, thicknesses and roll lengths are available for household DIY and large engineering projects.

Industry Applications

The bubble aluminum foil insulation film is a multifunctional radiant barrier thermal insulation material for construction, industrial and agricultural fields, with core applications including:

Metal Roof & Attic Heat Insulation

Laid under metal roof panels and attic spaces, it reflects 97% solar radiant heat to block summer high temperature and retain indoor heat in winter, stabilizing indoor temperature and cutting air conditioning energy costs.

Wall, Sunroom & Partition Thermal Wrap

Installed on exterior walls, sunroom walls and internal partitions, it prevents heat loss and condensation, avoiding wall mildew caused by temperature difference and moisture penetration.

Warehouse, Garage & Container Insulation

Suitable for steel warehouses, garages, shipping containers and prefab houses, it provides waterproof, heat insulation and rain noise reduction, protecting stored goods from high temperature and damp erosion.

HVAC Pipeline & Mechanical Equipment Wrapping

Wrapped around air ducts, water pipes and industrial machinery, it reduces pipeline heat loss, avoids pipeline condensation dripping, and weakens equipment operation noise transmission.

Agricultural Greenhouse Thermal Barrier

Used as reflective heat insulation lining inside greenhouses, it stabilizes internal temperature, reduces temperature difference between day and night, and improves crop growth environment.

RV, Trailer & Mobile Building Insulation

Lightweight flexible roll material for RV walls, floors and ceilings, easy to cut and install, achieving lightweight thermal insulation for mobile living spaces.
