Serious weatherizing of exterior doors
Gents … I am surprised that I cannot find internet guidance on optimum door sealing design, tested methods and materials. I have a mid-range Lowe’s back entrance door facing NW that allows some air in at the bottom corner all the time and when it’s windy the air leak spreads up the jamb and across the threshold.
I have considered the following solutions:
– over-center compression latches – one at upper and one at lower ends of lock side of the door to push the door against the stops
– an aftermarket metal threshold jamb that pusheson the door base
– a new 5 or 6 fin bottom sweep
– corner pads on the two bottom corners (the most common point of air leaks on all doors, I understand, is the bottom corners)
I looked at Passive House sites and found nothing inspiring.
My front door is the same quality but not exposed to the wind. I was able to make it pretty tight with a strike plate adjustment but I will probably do the threshold stop and corner pads there as well.
What say ye?
PS my very well airsealed and insulated house has passive/manually controlled air inlets in strategic places for fresh air ventilatin and make up air at the neutral pressure plane as well as near the wood stove, dryer, range hood vented areas so I don’t need the fugitive infiltration at the doors.
