Isoflect Recuperator
The membrane for the back of the radiator. It is bonded to the wall, with the aluminium facing the radiator: the wall absorbs less heat, and the heat radiated by the radiator is redirected towards the room.

One roll, two faces, a single purpose
6 m² roll
0.6 m wide × 10 m long, with a thickness of 6 mm. It is cut to the size of each radiator.
Aluminium towards the radiator
The aluminium face is oriented towards the radiator and redirects the heat radiated by it towards the room.
Foam towards the wall
The polyethylene foam face is bonded to the wall with the two double-sided adhesive strips.
The heat remains in the room, not in the wall
The wall absorbs less
Without a membrane, the wall behind the radiator takes up part of the heat. With the Recuperator, the aluminium face is located between the radiator and the wall, and the wall absorbs less heat.
Thermal radiation, towards the room
The aluminium redirects the heat radiated by the radiator (thermal radiation) back towards the room.
Three steps
1. Cutting
Cut from the roll a piece suitable for the back of the radiator.
2. Bonding to the wall
Bond the membrane to the wall behind the radiator by its non-aluminium face, using the two double-sided adhesive strips. The aluminium remains facing the radiator.
3. Stronger bonding, if required
If a stronger bond is required, add further double-sided adhesive strips.
