Ontario Thermal Wall Systems is a company that prides itself on building sustainably. We take compressed agriculture waste fibre from the farming industry and use it as the core of our wall system to achieve an insulation that is 2 to 3 times better than a conventional construction.  Packed into a wooden frame, the insulating core is then encased in stucco on both faces, effectively sealing the wall.  These modular walls are manufactured indoors, in a controlled environment, and then shipped to site and installed on any conventional foundation - in a fraction of the time.  This SIP wall system completely replaces the conventional exterior wall system.
