We offer both Somfy and Alpha motors in our exterior screens. Both are great options and we recommend both of them depending on the install situation.
Because Alpha is the newer motor supplier of the two, we’ve been testing it a bit more rigorously and trying to find out where it will finally fail. Last week the folks in the shop made this contraption to mount a housing and roller-tube to a forklift, so we could try pulling different things with the Alpha motor. Check out this video below of our standard Alpha motor (Alpha Pro+OD 5030) pulling a truck!
