Observations from Seed Eco-Home 1

  • Stringer stairs are notoriously noisy. Stringers bend under weight, and must be supported if they are 16' long. If there are 3 stringers - these must be cut perfectly - otherwise the treads won't even sit flat, and possible motion means sqeaky stairs. Further - it's not only one tread that sqeaks - it is treads/stringers upstream that can squeak.
  • Squeak is solved by stringerless stairs:

  • JLC - [1]
  • Instead of notching stringers - here is how to use flat stringers, and add the steps as additional pieces. [2]. Expensive for their system, cheap for 3D printed equivalent.
  • If you have a point of attachment for risers, these can be built into a wall
  • This means that you can avoid stringers in a stairwell, if you fatten up the treads!
  • Stringer spacing depends on thickness of treads - 40" stair can use 2 stringers if you use a 4x12 tread [3]
