Air-tight letterbox for a sealed house?

    I am doing up a house which will be air tight and with heat recovery etc.
    I want my post delivered into the house, old-style, but I can't find any source for a postbox that is air-tight enough.
    The idea is simple enough - the post is put in from the outside and collected inside, through some airtight system. It can't be complicated technically.
    Any leads welcome or if anyone did a DIY version of this

    Is there some specific reason why a wall mounted mail box isn't an option?

    You can get nice looking ones which are very secure..

    I don't think you should be looking at compromising your front door.

    'Is there some specific reason why a wall mounted mail box isn't an option' - as is said, I want the post delivered into the house, old-style. The house is being future-proofed for old age etc and having to go outside every day to check the post with a walking aid or in an electric wheelchair one can do without.

    'I don't think you should be looking at compromising your front door.' - I want to build it into the wall, through the cavity. Something like An-Post's Delivery box, but with a slot going through the cavity and an air-tight door/hatch on the inside.

    As I said, I'm looking for sources or, any DIY example.

    You could buy a box that is IP65 or NEMA-4 waterproofed and put it inside the house, and cut a letterbox in the back of the box.

    The door is designed to be watertight or near-watertight so it should be pretty air-tight.

    Something like this (you should be able to get something similar from an electrical wholesaler in Ireland).


    http://www.ebay.com/itm/BUD-Industries-Series-SNB-Steel-NEMA-4-Sheet-Metal-Box-with-Mounting-Bracket/322251423417?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D888007%26algo%3DDISC.MBE%26ao%3D1%26asc%3D20131227121020%26meid%3D3e0714f9b4d8403ba45c28abeabb342e%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D191804998922

    The issue i would see is getting something that is convenient to open.

    Another thing you could do is make a box and use a PVC window, with the glass replaced with a sheet of plastic (or have glass, so you can see if there's any mail in there)
