Structural Insulated Panels

So, what is a SIP?

and why would I want it in my new hybrid or timber frame home?


SIP stands for Structural Insulated Panel.


A SIP is basically a sheet of OSB or plywood, a thickness of rigid foam insulation and a second sheet of OSB that create a “sandwich.”

So the real question is, “Why would I want to use SIPs in my home?” Well there are several reasons to consider, so many in fact that we feel they are a great construction method for use with our timber frame packages.

These are structurally sound enough to build a home by using the panels to form the walls and roof of the structure, but there are a number of other reasons.

What does SIP have to do with Mill Town Log cabins?

Your log, timber or hybrid home can employ SIP construction, and we will supply the panels, custom manufactured for your particular floor plan, delivered with your other building materials in your final package.

Your home or commercial building design can incorporate components of wood, stone, metal, stucco, siding and more. To see how SIP works with our timber frame kits, click here.

Benefits of Using SIP


  1. Energy efficiency – imagine having the cost to heat and cool your home being HALF that of a conventionally framed home for the rest of your life. Would you enjoy that? It’s not only possible with a SIP home. It’s documented! SIP panel homes offer a few big advantages. LESS seams means less air infiltration. Higher R values mean less heating/cooling capacity needed to keep your home comfortable year round.
  2. Faster to build – our SIPS are delivered to your home site already cut and numbered. It is like a giant jigsaw puzzle. In a typical home the panels can be assembled in just a couple of days, with NO WASTE! Saving time saves you money!
  3. Structurally capable – SIP panels are two to three times more structurally capable than stick framing. Study after study shows how a SIP panel home will keep you safe as well as warm.

The bottom line is that structural insulated panels are cleaner, greener, safer and will make your cost of ownership of the timber home you’ve dreamed of the envy of everyone you know!
