Timber Frame Buildings

Timber framing is truly, the unique craft of intricately joining and pegging massive timbers together to create a strong structure that uses less wood than conventionally framed buildings. Many timber frame structures have survived for hundreds of years.

For over 22 years, Jeff Dunham has been a Timber Frame builder and installer of Structural Insulated Panels (SIPs). His work has included residential, commercial and industrial projects throughout the New England area.

Bringing to the projects, pride and progress, Jeff believes in teamwork to reach the customer’s goals. He understands the complexity of doing projects right and within the scheduled budget and time frame by planning and understanding each task before the project starts. Jeff strives to simplify complex projects one step at a time.

Its our goal to provide builders, architects, engineers, timber framers, contractors and general contractors with the best SIP products that money can buy.

Structural Insulated Panels (SIPs)

What are SIPs?

Structural Insulated Panels (SIPs) are custom built, prefabricated panels that can be used for walls, floors and roofs. SIPs are typically made from rigid foam insulation sandwiched between two sheets of oriented strand board (OSB). There are many different types of skins available, including, but not limited to: metal, plywood, cement and magnesium oxide board (MgO).
