The Glulams are extended out to create a spectacular overhang that gives you a definite feeling of a good solid house. You also get the benefit of built-in shade if you have a deck on the front of your house. Again, the sun is the most hot when it's straight up above you and the added overhang that glulams offer helps to shade that area while letting the sun's heat shine on the deck at the cooler times of the day be it morning or evening.
As you can see the benefits of using glulams far out-weighs the extra cost and you get a much better house because of them. It's really how houses were meant to be built and although this method may not be for everyone, for a lot of people it wouldn't be any other way. As a builder it gives me great satisfaction to watch people's re-action when they walk into a house that have glulam beams exposed. It's definitely the "wow" factor that I see.
question: Looking to build a new staircase in my house - open concept with notched stringers. Thinking about using glulam 2x12's or thicker as the stringers and using solid fir for the treads. Striving for a very minimal japanese look. My question is, is it safe to notch out glulam? How much will the beams cost (2x12's @16')? Are they easy to source? And lastly will i be able to match Fir treads or even get glulam for the tread material?
Sorry for the wait, it's been busy here.
Thanks for your question.
I've built stairs with Glu-Lams, I did however,
route the treads in.
You could notch them keeping your 'throat" at
least 5" which should be possible if you use an ideal
rise and run of 7" and 10" 7 being the riser.
You can also use glu-lam treads.
As far as cost, they are expensive and I wouldn't guess at the cost.
