We are planning to extend what has been a walkway on the upper floor. It is supported by a 42 x 315 glulam beam, which according to the construction drawing should be replaced with a 90 x 315. Now that we have spoken with the carpenter, he thinks it should be possible to reinforce the existing one by gluing and screwing on an identical one. Is it OK to do so?
Then I'm wondering in that case, which dimension? 42 x 315 no longer seems to be available as standard and neither does 56 x 315. Would 66 x 315 then be applicable?

42, 56, 66 and 78 mm wide laminated beams are produced by splitting. They are mostly stocked in smaller heights. However, all sizes are usually available as special order items. If you glue a 56x315, the result is comparable to 90x315. 2 pieces of 42x315 are not enough to meet the architect's requirements.
