In wall slide vs through the wall slide

[dosbeagles]

Hi,  reading about slide units I see there are several types.  The first one is the in wall vs through the wall.  I thought all slides were both in and through the wall.  What is the difference between the two classifications and which one is newer technology  and your opinion as to which one is better and why.

 

Thanks in advance for your help.

I agree with you. How could a slide not be in and through the wall? Thats why they are "slide outs". Even a slide in slide will be through the wall.

I think they're referring to "surface" through the wall versus "flush" in the wall slides. Surface slides when retracted still protrude slightly past the exterior wall and seal around the opening with an obvious lip. Flush slides retract into a recessed wall opening presenting a smooth flush exterior wall appearance, with the seal against a recessed lip.

It has to be just different manufacturers/dealers have different terminology when describing slides.  When building any RV with a slide there really is only one way.  You have a wall with a opening and a pre-built "box" gets set inside that opening, and abra cadabra…….we have a slide out....

The Lippert website touts the qualities of both in wall slides and through the frame slides.  But I am still not seeing the benefits of one over the other.  I believe the through the frame slide and through the wall slides are the same.

Might the difference be in where the hardware is located? Some in the walls of the slide and others have it under the floor of the slide?

I imagine something like this is the case.  The Schwintek slide system has the mechanism completely enclosed in the wall, with no beams or other mechanisms located below the slide. 

Many other systems support the slide on a pair of beams that are driven either hydraulically or electrically (rack and pinion) with the support beams exposed below the floor and in either penetrating the trailer frame or riding above it. 

Perhaps this is the distinction between the "in the wall" (Schwintek) and "through the wall (frame?) systems.

NuWa called them "glide rooms."
