Last season on the bathroom window I tried installing a sheet of acrylic to make it a bit more efficient. It worked quite well I believe, but when it was time to remove it, I had a devil of a time pulling it away from the “draught attack” caulking I had applied.
This year I thought I’d see how well Dollarama painters tape could stand up for the duration of the heating season.
I believe it doesn’t look too bad, but we’ll see how well it stays up as the season goes on.
