What are the benefits of installing this Letterbox Draught Excluder?

A bit like with our chimneys, have an open letter box is like having a small open window, drawing warm air out of your home and allowing cold air in. We can plug our chimneys with a Chimney Sheep® so why not draught-proof our letterboxes too with a letterbox draught excluder?

Doing so will:

  • Save you money – whilst your letterbox is often overlooked as a serious source of concern when it comes to draughts, if you are keeping a close eye on your energy bills, every little helps!
  • Make your home more energy-efficient – installing a letterbox draught excluder into your home will make your home more eco-friendly by preventing warm air from escaping and cold air from invading. This means your heating system will no longer need to work as hard to reach the temperature which you desire.
  • Ensure your home is warm, cosy and dry– stopping warm air from escaping and cold air getting in will help to keep your home toasty and dry. Rather important on those cold and rainy winter evenings in front of the TV!

Each of our letterbox draught excluders is made in the UK by Stormguard who is one of the UK’s leading manufacturers of draught excluders for doors and windows, so you know it is going to be good!

How else can I draught-proof my house?

You may have guessed but we are rather big fans of draught-proofing and there is good reason. IT WORKS whilst being easy, cost-effective and a pretty quick way for you to feel warmer.

If you have a house with an open chimney we would always suggest draught-proofing your chimney first. It is often the biggest source of heat loss in homes with the Building Research Establishment (BRE) stating that 80 cubic metres of air is lost out of a chimney per hour. The best way to draught-proof your chimney is with one of our removable chimney draught excluders, a Chimney Sheep®.

Your house may have lots of other draught sources too, so how do you deal with those? Well, you can track down all those pesky draughts with a Smoke Pencil. The most common though are windows and doors which can be easily fixed. Take a look at some of our other draught-proofing measures like our keyhole covers and door draught excluders which will ensure you keep your warm air in your home where it belongs.

    I always had the entrance chilly because the old letterbox wasn’t good. After installing this one I couldn’t believe how good it is. Easy to install.

    Stops the draught

    Really pleased with this, does the job and stops the draught, however, ordered a second to fit on the outside of the door and it came with 2 screws instead of 4 so had to find 2 to fit it.

    An excellent letterbox and it has stopped the draft making the inside flap bang loudly so it looks good and has done exactly what I needed it to do.

    Great sturdy letter box.

    Really good product and very sturdy. Only issue is that there are 6 holes for the nails but only 2 nails provided. I had to use the nails from my old letterbox. All in all a great product and took me 5 mins to drill in.

    Excellent Product from Stormguard

    Letter Box draught excluder was delivered quickly and arrived in perfect condition. The product itself is well made, even though the listing gives the impression of aluminium construction, this is ONLY the flap, the framework around is of a strong plastic construction in a grey/silver colour – once place it looks fine. Excluder was very simple to install, I was replacing a damaged one, so I was able to simply screw this in place using existing holes in rear of my door. The brush bars can ‘restrict’ mail being pushed through – I remedied this by simply removing the brush bars and using a sharp scalpel, took around 5mm from both the top and bottom brush bars. This will not effect the ‘draught’ exclusion, as the flap itself also has a strip of draught excluder along the inside bottom. The removal of a small amount of bristle, was great – I was able to push flimsy envelopes through the box with ease. The brush bars can easily be removed completely if you desire, then there will be no restriction at all. It certainly looks good quality and makes the inside of my door look neat again. Would recommend this product.

    Good interior letter box with a small niggle

    Very good interior letter box, you can tell it’s good quality that has been well made (apart from the top brush but keep reading). Keeps out draughts perfectly and also looks nice unlike the cheap plastic type ones…however when I came to install this I noticed the bolt holes for my external letter box lined up in the exact same position as the interior holes for the letter box causing a bit of modification, also as others have stated on here the top brush sometimes comes out when the post is delivered causing you to put it back in place, sorted with a bit of super glue not a major problem but still annoying (hence 4 stars)…apart from that very pleased with my purchase.

    Not right for us

    This didn’t quite meet our needs, but that was our fault and nothing to do with the actual product. It was delivered in good time and was as described.

    Perfect for this time of year. It keeps the cold out and stops all the drafts. Postman has a bit of difficulty getting the letters through, but other than that its great

  21. C. Cummings

    Cuts out draughts completely

    This is brilliant at keeping out the gale which used to come through the letter box straight into our living room. It looks very smart too and goes well with the chrome door furniture, the only down side is that the brushes are a bit stiff and the postman has to push to get the letters through.
