A SIMPLE DIY LAYER FOR BETTER THERMAL MANAGEMENT

REFLECT RADIANT HEAT BACK TOWARDS THE ROOM

This reflective double-bubble insulation roll combines aluminium foil surfaces with polyethylene bubble layers to create a lightweight, cut-to-size thermal barrier for suitable household DIY applications – including installation behind compatible wall radiators.

WHEN HEAT IS DIRECTED TOWARDS A COLD EXTERNAL WALL

ADD A REFLECTIVE LAYER BEHIND SUITABLE WALL RADIATORS

Radiators fitted against colder external walls can direct some radiant heat towards the wall surface. A reflective layer positioned appropriately behind the radiator is designed to redirect a portion of that radiant heat back towards the room instead.

Cold wall and draught conditions around an uninsulated household area
This material does not repair draughty windows, gaps or failed seals by itself. Draughts should be addressed at their actual source where appropriate.

01 / RADIATOR REFLECTOR APPLICATION

CUT THE ROLL TO SUIT YOUR AVAILABLE WALL SPACE

The 60 cm × 5 m roll can be measured and cut for suitable installations behind wall-mounted radiators. Its reflective aluminium surface is designed to reduce radiant heat being directed straight into the wall and redirect some of it towards the occupied room.

Reflective insulation sheet cut to size behind a wall radiator
Heating performance and potential energy savings vary with radiator type, wall construction, existing insulation, room temperature, installation method and other building conditions.

02 / DOUBLE-BUBBLE CORE

AN ADDITIONAL THERMAL LAYER FOR SUITABLE DIY PROJECTS

The internal polyethylene bubble structure creates a lightweight insulating layer between the reflective surfaces. When installed appropriately, the combination can help reduce heat transfer through the treated area.

Double bubble construction of reflective aluminium insulation film
The material should not be described as an airtight draught seal unless the entire installation is specifically designed, joined and sealed for that purpose.

03 / MULTI-LAYER CONSTRUCTION

ALUMINIUM FOIL, PROTECTIVE FILM & POLYETHYLENE BUBBLES

The roll combines reflective aluminium foil with PE protective film and a polyethylene bubble layer. This creates a flexible sheet that can be trimmed for suitable household insulation and heat-reflection projects.

04 / CUT-TO-SIZE DIY FORMAT

ONE 5-METRE ROLL FOR DIFFERENT SUITABLE HOUSEHOLD PROJECTS

The flexible roll format allows sections to be measured and trimmed for different surfaces and projects. It can be used where a lightweight reflective insulation layer is appropriate, provided the location, temperature and installation method are suitable for the material.

05 / MOISTURE-RESISTANT SURFACE

FOIL-FACED SURFACE HELPS RESIST EVERYDAY MOISTURE

The foil and protective-film construction provides a surface that can resist incidental moisture better than many absorbent insulation materials, making it practical for suitable indoor DIY uses.

Foil-faced reflective insulation with moisture-resistant surface
No vapour-control rating, waterproof rating or sealed-system specification is provided. Do not treat the roll as a guaranteed waterproof membrane or certified vapour barrier.

WHY THIS FORMAT IS USEFUL

LIGHTWEIGHT, REFLECTIVE & EASY TO CUSTOMISE

Reflective Surface Designed to redirect radiant heat rather than simply absorb it.
Double-Bubble Layer Adds a lightweight insulating air-cell structure.
60 cm × 5 m Roll Provides material that can be cut for different suitable projects.
Flexible Sheet Easier to trim and position than rigid insulation boards.
Silver Finish Reflective aluminium appearance on the insulation surface.
DIY Friendly Measure, cut and secure using an appropriate fixing method.

SIMPLE CUT-TO-FIT INSTALLATION

MEASURE, CUT & SECURE

The roll is designed to be trimmed to suit the available installation area. Before fitting, make sure the surface is clean, dry and suitable for the fixing method you intend to use.

Measure the area where the reflective sheet will be installed.
Cut the material carefully to the required dimensions.
Secure it using suitable adhesive pads, tape or another appropriate fixing method.

IMPORTANT INFORMATION

INSTALLATION & SAFETY NOTES

  • When fitting behind a radiator, maintain all clearances required by the radiator and heating-system manufacturer.
  • Do not cover radiator vents, thermostatic valves, electrical controls or areas required for airflow and servicing.
  • Keep the material away from open flames, exposed heating elements and other direct high-temperature sources.
  • No maximum service temperature or fire-resistance classification is provided in the supplied information.
  • The product is not stated to be a certified fire barrier, waterproof membrane or vapour-control layer.
  • Do not use it to conceal active damp, leaks or condensation problems. Identify and correct the moisture source where necessary.
  • Check that adhesives or tapes are suitable for both the insulation material and the wall surface before installation.
  • Test fixing products on delicate painted or finished surfaces, as removal may affect some coatings.
  • Effectiveness varies with installation, air gaps, wall construction, existing insulation and room conditions.
  • Take care when cutting the sheet and keep cutting tools away from children.
