The properties of concrete have shown to be far more beneficial than wood framing, say specialists in the construction field.
A wood structure cannot compete with a concrete one in terms of energy use, cost savings, durability, sound resistance, safety from fire and wind, nor in terms of the superior, allergen-free air quality for the occupants they say.
Today, the more progressive builders have switched to a system for walls, called insulated concrete forms, which interlock like Lego to erect the building.
Not all builders have switched away from wood yet however, so concrete walls need to be requested by the homeowner.
But one Canadian company, Nudura, has blazed the trail for insulated concrete forms (ICFs) throughout North America with an impressive degree of success.
Nudura forms are in demand south of the border as much as they are here. To reduce your home’s carbon footprint and costs, while you improve the structural and residential quality, here’s the scoop on this concrete technology:
Each Nudura form is pre-assembled for quick and easy use at the building site. The forms are designed with two thick panels of foam (expanded polystyrene) connected together with a unique (and patented) web system.
It is stacked, steel reinforced and filled with concrete, all of which results in superior insulation as the wall is firmly erected.
To accommodate all types of building requirements and designs, these specialized interlocking forms are available in several widths up to 30 cm (12 inches) and also in a variety of shapes.
On the outside, homeowners can choose an eye-catching finish like stone, or stucco, brick, wood or a combination of any favourites.
