Beams, a Floor System and Foam.
Since the garage will be a woodworking shop, I needed a clear span across the garage for woodworking tools. The span across the garage is 24' and required a 4 ply 18" LVL beam. The beam is installed flush to the top of the joists. The rest of the floor system is 2x10. The beam was prepared according to the bolting pattern provided by the truss company (W. G. Garland Trusses, Carbonear, NL). Photos 3-1 to 3-3 show the lift and final position of the beam. With these major components in place we could commence with joisting and flooring the second level.
This was the end of a major milestone for the build...and the beginning of another! Time to start sheathing the exterior with foam! The foam product used on the walls is called True Wall, it is a type 1 EPS foam with slots for strapping. It is usually purchased with a thickness less than 3" and can accommodate 1x3 strapping but can be manufactured to meet any specifications. In our case we used 2x4 slots every 24" to secure the foam with screws. I have tried several ways to cut foam. Depending on thickness different methods work better/worse than others. For thin foam i.e. 1" or less I like using a utility knife. Its sharp and you can work quickly with a strait edge. If the foam is greater than 1" thick, I find that utility blades wander. For really thick foam i.e. 4"+, a small, fine toothed, handsaw works great. For 2"-3" foam, I find that a broad knife with the edge sharpened to a razors edge works the best. You can use a straight piece of 2"x4" lumber to guide the broad knife (Photo 4-1). Once the cut is scored part way through, the score will guide successive cuts without a straightedge as long as you work slowly (Photo 4-2). Photo 4-3 and 4-4 show the north wall after a couple hours work....easy peasy!
Lots of stuff completed this week and we are moving along nicely. Framing the second level with commence next week.
