DURISOL Insulated Concrete Forms

High Performance Building Envelopes

Durisol insulated concrete forms are the original ICF system. Since 1945, they have been manufacturing the only reinforced insulated concrete forms that does not use foam or polystyrene. 

Durisol Insulated Concrete Forms (now rebranded as Nexcem) provide a superior concrete green building technology that delivers costeffective, high-performance structures. Made from 100% recycled, clean, waste wood, Nexcem concrete structures are safer, quieter, more comfortable, energy efficient, structurally secure, and environmentally  responsible than any other concrete building system available on the market today. Nexcem has selected ROCKWOOL insulation for the past 15 years as the supplier of choice because of the product’s dimensional stability, low VOC emissions ratings, natural material status and R-value stability.

The Durisol Forms are optimized to eliminate thermal bridging and maximize the thermal mass benefits of the building envelope.

Indoor air quality is another key component of the DURISOL building envelope. Because Durisol does not absorb water, it moderates humidity levels, inhibits mold growth and contributes significantly to a healthy living environment.

ROCKWOOL is complimentary to this purpose and does not off-gas or release VOCs into the air for occupants to breathe in. 

The Durisol ICF Building System is the only building envelope product specified by Third Line Homes at the Terracewoods development in Meaford, Ontario. This development, built in partnership with the (Mike) Holmes group, demonstrates how DURISOL and ROCKWOOL are an integral part of building quality, healthy, strong and environmentally conscious homes that will provide homeowners with an unparalleled living experience and uncompromised air quality and comfort.

To ensure the homes are is all-inclusive in all aspects, the developers took orientation and lot geometry into consideration when designing the home. Sun-angle simulations were performed accounting for natural shading and architectural features to maximize the usage of available free energy for storage within the Durisol wall system. An ensemble of extended overhangs, balconies and deciduous trees to the South of the property shade the summer sun without interfering with the solar energy beaming into the house during the winter. At the same time, low solar heat gain windows are used on the western exposure to minimize the cooling load.
