Heating Efficiency / Insulation - The Ecoflap - saves energy by stopping draughts coming through your letter box
The Ecoflap fits on the back of your letter box, and is designed to exclude draughts and inhospitable weather from your home. It's quick and simple to install, and starts saving you energy straight away.
Ecoflaps replace the brushes, seals and outward opening gravity flaps on the inside of the letter box, traditionally used to help keep draughts out. The difference is that an Ecoflap is totally draught proof and adjusts automatically to any size of delivery - up to A4 and including thickish newspapers and magazines.
You keep the existing letterbox exterior (or change if you like) to retain the aesthetics of your front door.
