What is LSL rim?
TimberStrand® laminated strand lumber (LSL) is an engineered lumber that is consistently straight and true — characteristics that combine to create superior rim board material. TimberStrand Rim Board is dimensionally stable and excels at transferring vertical and lateral loads to the foundation.
What type of joists is used with LVL or LSL rim board?
iLevel® Trus Joist® 11⁄4″ TimberStrand® laminated strand lumber (LSL) rim board supports vertical loads and provides the nailing surface necessary to adequately transfer wind and seismic loads.
Can LSL be used for floor joists?
TimberStrand® LSL is an ideal solution, providing an alternative to solid sawn floor joists, especially where longer lengths and greater stability are required.
What is LSL in framing?
TimberStrand LSL treated sill plates are long and straight so walls get off to a square start.
What is stronger LVL or LSL?
5 days ago
Laminated Veneer Lumber (LVL) Its shear strength is superior to LSL but doesn’t quite match PSL’s ability to withstand bending stress. LVL is more expensive than LSL but is affordable compared to PSL and glulam.
Do floor trusses need rim board?
Floor truss systems can be designed and built for step-down floor level changes or cantilevered balconies, a design innovation not offered by other floor joist systems. Plus, floor truss systems don’t require blocking panels, web stiffeners, squash blocks, or even rim or band boards to support edges or exterior walls.
Can you use LVL for rim board?
LP LVL Rim Board is designed to be used with LP I-Joists and LP LVL beams to support vertical and lateral wall loads as part of a floor or roof framing system.
Is LSL stronger than dimensional lumber?
Laminated veneer lumber (LVL) studs can be two times stronger in compression and tension than standard framing lumber of the same dimension.
What is stronger LSL or LVL?
Which is stronger LVL or LSL?
Laminated Veneer Lumber (LVL) Its shear strength is superior to LSL but doesn’t quite match PSL’s ability to withstand bending stress. LVL is more expensive than LSL but is affordable compared to PSL and glulam.
What is difference between LSL and PSL?
LSL is also ideal for use in rim conditions due to minimal shrinkage, cupping, and high fastener holding strength when used in highly loaded diaphragms or for shear transfer at plywood shear walls. Parallel Strand Lumber (PSL) is manufactured from veneers laid into long, parallel strands and bonded together.
Is rim joist necessary?
Yes, if your framing a house or a deck you’ll need a rim joist. They create the edge of your floor framing and close off the open edges.
What is the purpose of a rim joist?
In the framing of a deck or floor system, a rim joist is attached perpendicular to the joists, and provides lateral support for the ends of the joists while capping off the end of the floor or deck system.
How thick should rim joist be?
The blocking or rim joist must be the same depth as the joists and at least nominally 2-inches thick.
What size should rim joist be?
Rim joists typically are made of the same material and are the same size as the other joists. This ensures that the rims are flush with the joists along their top edges, all of which are covered with subflooring. The conventional material for joists and rim joists is solid framing lumber, either 2 x 10s or 2 x 12s.
Which is stronger LSL or LVL?
Which is stronger PSL or LSL?
Due to its high allowable shear strength, LSL beams have the capacity for larger penetrations than other engineered wood beam options. While not as strong as LVL or PSL beams, LSL is generally cheaper and is ideal for short spans.
Is a rim joist load bearing?
On a deck, the rim joist isn’t typically considered load bearing unless a wall is built atop it. But it’s still very important. They provide strength to the floor joists and keep them upright just like the floor joists inside a house.
Do rim joists need to be doubled?
It is advisable to increase the rigidity and strength of your deck’s rim or perimeter in order to reduce bounce and provide a solid foundation for your rail system. This can be accomplished in a couple of ways. You may want to install double rim joists across long sections to respond to the flexibility of the material.
What R value do I need for rim joist?
Rim joists are above grade, so it makes sense to insulate them to the same level as above-grade walls—a minimum of R-13 in climate zones 1 through 4, or a minimum of R-20 in climate zones 5 though 8.
