Hey all,I have an older (10 year old) cheap garage door unit for my 2 car garage door. I dont recall the model (label has since worn away). I recently bought a Chamberlain 1.25 HP smart opener. Partly bought it for the ability to use smart phone (and hopefully connect with my openHAB setup to monitor/control it). Where I am at it gets to about 110 degrees some days, though usually in the high 90s during summer, and drops to the 30s in winter. I was told adding foil backed Styrofoam to my door would help reduce heat (and keep it warmer in winter) by about 10 to 20 degrees depending on some factors. I plan to just buy a 4x8 sheet of the 1/2" to 3/4" stuff and cut/fit it into the slots on my door. I think they are about 1" deep, and read that leaving a little space (thus taping it to the metal framing) would further increase the trapping of heat/cold. I run my home network in the garage, as well as a home gym, so would ideally like to not sweat to death in summer and freeze in winter, thus my desire to line my door with the foam.With that said, I was told and/or read that adding foam adds weight to the door, though not much. I am hoping this new 1.25 HP unit is capable of lifting the door, but was hoping one of you that may have done something like this would know. It is a standard metal (aluminum?) door with 5 sections, one of which has windows in it, which I do plan to cover with foam inserts as well.The bigger question is if I need to have the spring replaced, which I am fine with, and probably will do anyone since several neighbors have already had their springs snap and had to get new ones.. not sure how long they generally last, but its been 10 years, so with the added weight, thinking it may be a good time to get that done anyway. via /r/DIY http://bit.ly/2Wm2DOD
