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.

Isoflect Recuperator installed on the wall behind the radiator, with the aluminium facing the radiator
In brief

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.

Section: the wall, the Isoflect Recuperator membrane and the radiator
How it works

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.

Installation

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.

Installation: the Isoflect Recuperator membrane is bonded to the wall behind the radiator
