Timber Frame and SIPs

The combination of heavy timber framing with an insulated panel wrap produces an extremely energy efficient home.

The outer walls, roof and floor constitute a home's building envelope.  How well it is sealed and insulated determines how energy efficient it will be to heat and cool.  Timber frame provies the structure and it is up to you to choose the most energy efficient envelope.

Insulated panels offer more energy efficient qualities than alternative building systems such as stud framing with fiberglass insulation.  Fiberglass is sometimes used in furnace filters because air moves through it so freely.  Rigid insulation is used as a solid component insulation in many industries due to its inherent efficiency and lack of air movement. SIP wall assemblies tend to be well sealed, enhancing energy efficiency.  Lesser air leakage means fewer drafts, less noise, lower energy bills and a much more comfortable indoor environment.

SIPs also reduce construction waste; they can be delivered pre-cut to the precise dimensions required.  Each panel contains the structural, insulation, moisture barrier and sheathing of the wall system.  OSB is the most common sheathing and facing material in SIPs, reducing wood use by as much as 35% and reducing pressure on mature forests by allowing the use of smaller farm-grown trees for structural applications.  Exterior grade plywood requires more mature timber.

 

It is possible to save 40-60% on energy costs with timber frame and SIPs.
