House Framing With Advanced Framing Techniques
Framing with Advance Techniques
Framing a house with Advanced Framing Techniques. What are we talking about when we mention advance framing techniques. I have been involved in conventional house framing for over 33 years now and I can tell you that these Advanced Framing Techniques are revolutionary.
In conventional house framing we are use to building with either 2×4 or 2×6 construction with a double top plate and your choice of a variety of sheeting options. You will typically find studs set 16” on center and double or even triple header material. Along with this you will find extra cripple studs under openings at 16” on center spacing and triple studs in exterior corners.
Now understand that this is how most everyone has always built. But we are about to change all that. The system I am about to detail is the newest standard put out in 2012 by The Engineered Wood Association .
Here is how they describe Advanced Framing. Advance Framing is a system of framing techniques base on optimizing building materials to produce wood framed buildings with lower material and labor costs than conventional framed structures.
They go on to say that bulders who use these practices along with effective insulation details, boost the building’s efficiency to meet today’s energy code requirements while also optimizing framing material usage and reducing wood waste.
When properly designed and constructed, these advanced framed walls that are fully sheathed with wood structural panels made of products like plywood, or oriented strand board(OSB), create the structural strength needed to safely withstand the forces of nature.
Notice: While these practices have been around since the 1970’s, they where first developed by the National Association of Home Builders(NAHB). They are regaining popularity because of today’s growing interest in energy conservation. This writer strongly urges you to consult your local building official early in your design process to verify and obtain acceptance of the usage of the following practices and techniques in your jurisdiction.
Here are the key advanced framing practice changes
1. Switch to 2×6 studs to increase cavity insulation depth and meet R20 energy code requirements. (Especially important in colder climate zones.)
2. Where permitted by structural requirements, change the wall framing module from 16” on center to 24” on center to reduce framing cost. Retain the use of double top plates to avoid in-line or stacked framing alignment requirements.
3. Incorporate intersecting wall techniques and energy efficient corners like three stud corners and ladder junctions, which allow for greater insulation volume. Implement energy-efficient headers and limited framing around openings.
4. Eliminate double top plates. Because this step requires vertical framing alignment, including 24” on center floor and roof framing as well as non-industry standard stud lengths which may be difficult to find (Studs are precut to give you a standard wall height with two top plates and will be 1 1/2 inch short with a single top plate.), this is often the last technique most builders will consider.
The key here is to remember that if you are planning to implement any of these advance practices you must clearly show them when presenting your plans to your building department and make them aware of the system you intend to use.
