we had our first snowfall of the season last night and it reminds me that I need to put on my winter insulation I've insulated this workshop to be able to withstand the cold temperatures the outside so let me show you what I've done here let's open up the door the first thing I want to show you here is the floor this is a concrete slab there's no heating underneath and this is a floor that I put up on sleepers these are a pressure treated two by fours and in between here is rigid foam insulation that allows me to keep the cold out from underneath the slab in the workshop I heat my workshop for two reasons one is for comfort and the other is to protect my tools condensation can build up on cold tools when exposed to warm moist air a cast iron table surface is a good example of this this will retain cold temperature for a long time if I were to heat up this workshop rapidly I would end up with warm moisture coming in contact with a cold surface and that's when you get condensation that gets created and that's when you get rust it's similar to the condensation you'd see on a window the glass being the cold surface comes in contact with warm air and when the air temperature drops quickly it loses the moisture in the air and creates condensation that same process can happen to your tools so to protect your tools you want to make sure you don't have a large difference between the air temperature and your tool temperature the workshop walls are insulated to an AR 20 and the ceilings insulated to an art 30 all covered with fire rated drywall most challenging part about insulating a garage is dealing with the garage door it's something that's difficult to insulate I've replaced my garage door with a double insulated door that has a metal skin on each side and rigid insulation on the inside that wasn't enough though for me to deal with the wintertime so I've got an insulating blanket that I put on in the winter to help me provide that extra insulation I'll show you how it goes together first I unplug the garage door opener so don't have any mishaps and then I pull the insulation ahead of storage this is a two-person job so my daughter's here to help me out put this together the insulation we're installing here is a foundation blanket these are commonly found in big-box stores this is insulation espen glue the vapor barrier and so it becomes one sheet what I've done is just rule this around two by twos and we're securing them to the top of the garage door I've got extra vapor barrier and insulation here beyond the track and what I do is I just wrap it around the end here and then take a 2x4 and wedge it in place at the floor here I just pull out this excess insulation here wrap the poly underneath that and then tuck it back in to where I've got that gap between the floor and the garage door in the event I need to open this door for some reason I can pop the safety latch here on the garage door opener and knock the blocks on the side and I can easily lift it to slip something in and out I really need to do that in the winter time but that just gives me one option that I don't have this all sealed up tight with insulated walls ceilings floor and garage door it doesn't really take much to eat this space this is the heater that I use this is an electric heater it uses oil just circulating inside and I've got the ability here to set a frost setting and this is where I generally leave it I'm looking to keep my shop at 40 degrees Fahrenheit 10 degrees Celsius and that allows me to make sure that I don't get the shop cold enough that I can get condensation on the tools in there really cool days I will turn this up so that I get more heat but I really just keep it on a minimum setting and keep it on that frost most the time for the temperature zone I live in in January the coldest month the average low temperatures are 20 degrees Fahrenheit minus 70 degrees Celsius so you can get an idea of what it takes to heat my workshop I've also got supplementary heat above my workbench I've got this radiant heater and I can set this to a low setting for a high setting this feels a lot like being in front of a fireplace the radiant heat is really warming so I just used this in the cases where I'm not doing a lot of movement in the shop I might be working at my bench and I need just a little extra warmth for the space the last step is to reinstall the clamp wall back on my bench if you want to insulate your garage workshop here are some keys to success first of all insulate the walls in this - Building Code there are codes for drywall needs insulate the floor with a subfloor to get it off the cold concrete and then insulate the garage door with a foundation blanket to keep the warmth in and lastly heated to a constant temperature of at least 40 degrees to help prevent rust on the tools I hope this gives you a good idea of how you can insulate and heat your workshop this way you can enjoy it in the colder months and protect your tools from getting rust on them thanks for watching and enjoy your time in the woodshop you
