About Enclosures

Structural Insulated Panels (SIPs) are a very common choice for enclosing a timber frame. SIPS are two pieces of oriented strand board (OSB) sandwiched around an expanded polystyrene core — they provide the enclosure and the insulation all in one. SIPS provide an energy efficient enclosure, combining high R value and a tight seal. In addition, a SIP enclosure typically goes up in a matter of days, meaning your timber frame can be fully enclosed and all but dried-in almost immediately after raising.

DRYWALL: The first step Wind River takes to enclose your frame is tacking drywall wherever the timber frame touches an outside wall. Not only is it faster, but we feel that it gives a better finished product as opposed to the alternative of shimming the walls and sliding sheet rock in later.

WALL SIPS: The sheetrock is then screwed back into the panels to finish the walls.

WALL SIPS: Once a wall has drywall, the SIPs wall panels are slid into place along a plate. They are secured to other panels with nails and to the timber frame with wood screws.

WALL SIPS: The SIPs wall panels come with pre-routed chases for electrical wiring. There are two horizontal chases at typical switch and plug heights. In addition, there are vertical chases approximately every four feet where two wall panels come together.

WALL SIPS: A window and door package can be pre-cut out of the walls at the SIPs factory. When the walls are finished, the drywall only needs to be cut out of the windows and doors and your general contractor can begin installing.

T&G CEILING: It is very common for Wind River clients to choose aspen tongue and groove wood for their ceilings. The wood has a striking visual impact. Another advantage is the speed that Wind River can install the ceiling material. Working from the exterior to nail the wood onto the frame is faster and easier than working off of scaffolding or ladders from the inside of the home.

T&G CEILING: Locally sourced aspen tongue and groove is the most common ceiling material for the homes we build.

ROOF SIPS: When it comes time for the timber frame’s SIPs roof, a crane is again brought onto the work site. The panels are placed directly on top of the ceiling material.

ROOF SIPS: When the panels are ready to go, some hay hooks and straps are hammered into the SIPs and the crane swings them into place.

ROOF SIPS: The panels are set on the roof starting at the eve edge of the home and then added a row at a time moving up to the peak. Like the walls, the SIPs roof panels are nailed to each other and then attached to the timber frame rafters with wood screws. The final step is placing the sub-fascia material along the edges of the roof panels.

ROOF SIPS: After ceiling panels are in place, the home is ready to be dried-in by the general contractor before they begin finish work on the inside of the home.
