50yo house, 6 wooden doors into our home. Front door the worst (large warped). Used many solutions over the time but this solution made a permanent seal that will last for years.
Easy to install, used timber which was good I could groove out 2 doors with flywire screen doors to fit perfectly over the Hydraulic Door Closer. Install is forgiving as long as you close the door and lock first. You install it not based upon the door architrave but the close to seal perfect (ever warped doors). Used silicon spray to fit the seal runners into the timber made it easier to install, then paint and done.
Pic of our front door painted and sealing. Open it you will see it not straight fitting, it's about the door sealing not the architrave.
All up after 2 months installed these are doing the job even -8 nights with multiple wind storms can't feel the cold entering. Totally recommend!
