Sloping Floors

Question: 

In our one-year-old home, as you approach the hallway, the floor slopes downward. Our home inspector said that this was most likely due to the fact that the walls were resting on the floor as opposed to being load-bearing walls. What has been your experience with sloping floors in a new home? The floors are very flat elsewhere until the walls start. Do you think this sloping could turn into a structural problem eventually?

Truss Uplift

Question: 

I want to get a good definition on what causes “truss lift,” when the trusses will actually raise off the top plates of interior walls (even when nailed), causing the drywall to crack. Is it from drastically different temperatures in the attic and living area?

In Floor Radiant Heat

Question: 

Do you have any information on the use of in-floor radiant heat with 4x2 open-web floor trusses? Are there any adverse effects to the lumber as a result of moisture build up?

Penetration Of Fire Walls

Question: 

Can a roof truss penetrate a one-hr. tenant separation wall without having a one-hr. rated ceiling? The building official insists that the 2x4 chords are combustible and nullify the integrity of the one-hr. rated partition that is constructed in an attic above an 8 in. C.M.U. bearing wall. The partition consists of gypsum board attached to 2 x 4 stud framing. The building official insists that a ledger must be attached through the gypsum board to support the trusses each side of the wall. This is almost saying that any rated assembly must have bearing only on other rated assemblies.

Long Span Truss Installation - Educational Program

This program provides information on the installation of long span trusses. 

Building Better

If a new product can solve age-old building challenges, it can work anywhere—and help CMs become the go-to suppliers in their markets.

Long Span Truss Installation

Long span trusses can pose significant risk to installers. The dimensions and weight of a long span truss can create instability, buckling and collapse of one or many trusses, if not handled, installed, restrained and braced properly. As such, they require more detailed safety and handling measures than shorter span trusses. This research report provides guidelines for proper handling and installation of long span trusses for both wood and cold-formed steel.

Selling Smarter

Using components to solve old challenges in new ways means time and cost savings for builders and framers—and an expanding business base for component manufacturers.

Floor Vibration Causes and Control Methods - Educational Program

This program provides information on metal plate connected wood truss floor systems and managing vibrations. 

Sound Transmission in Wood Floor and Roof Trusses

Controlling sound transmission in buildings through wall, floor and ceiling assemblies is important for the comfort level and enjoyment of building occupants as they live, work and play in these buildings. This report aims to explore the methods one can use to reduce sound transmission in assemblies constructed with wood trusses.
