My beach beach house office is in a refurbished room of the house. Just looking at it, you can tell that it clearly used to be screened-in porch, that was later turned into an additional spare room. I had consistently thought for the first few weeks that the reason it was drafty was due to all of the windows plus the odd shape. It’s fairly split off from the rest of the house, so it doesn’t get much heat from the layout. Fortunately, the room has its own HVAC zone control with even a unusual type of heating than the rest of the house. While the beach house correct runs on oil heater, the spare room runs on an electric furnace system. Finally once Winter time gave way to Springtime, I decided to investigate the problem. It turns out the door was never properly sealed, the two of us suspect it was the certainly same door from the original screened-in porch in the 60s. Rather than take it off plus apply the gaskets, the older owners simply took some kind of industrial felt plus nailed it in long strips around the edges of the door with tiny decorative nails, and like trying to put a door sock around an entire door, however now that it’s warmer, we’ve taken the whole thing off plus just left the screen door shut. Rehabbing the door was entirely easy, the people I was with and I just brought it out to the driveway plus followed an instructional video with parts of the hardware store. We’re hoping this simple improvement will help keep the spare room warmer this winter, plus save us a few dollars on the central furnace bill.
