Kraft Construction

This project will be a one-level home with full basement located near Tupper Lake, NY, where Heating Degree Days approach 9,500. The builder encouraged the ready-mix contractor to use flyash in the concrete to reduce the carbon footprint. This is new for the contractor, along with the graphite additive Neopor, which is added to the expanded polystyrene (EPS) beads, which improves the insulation value from R-11 (typical) to R-27. Setting the forms is fairly easy and then concrete is poured to fill the forms, which becomes the structure.  The house will have a Hydronic boiler with sidearm hot water heater and an Energy Recovery Ventilator (ERV) to provide year round ventilation via air exchange.

This project was highlighted in an article by the Press RepublicanLink opens in new window - close new window to return to this page. for its innovative construction.

OSB material
The OSB material is drilled every 8" and filled with 2 part foam sealant,
assuring complete thermal seal between SIP joints

Foam and caulk installation 
After 2 part foam is applied every 8" along seam, caulk is
applied for final exterior seal between SIP

Neopor expandable polystyrene beads
BASF manufactured Neopor Expandable Polystyrene Beads
are injected into the SIP panel, improving the EPS R-value.
First SIP panels in US to be installed in Residential applications

Neopor SIP panel
The 12" Nepoor EPS SIP panel is hoisted in place
to join the ICF wall section. Note the 2 part foam
in place ready to seal the SIP to the ridge beam
