A Healthier Home & Environment
Building with ICFs is healthier for the environment in a number of ways.
It minimizes the number of different building products involved in construction.
Each building product in a timber wall requires a lot of energy to produce.
Fewer materials also reduce the amount of waste generated on the construction site.
ICF homes provide a healthy indoor environment, too. Nothing held within or ordinarily emitted by an ICF wall is toxic. The measurement of the air contents of actual ICF houses shows an almost complete absence of any emissions.
Construction Made Simple
ICF homes can be designed in any style, and will accept any traditional exterior finish including vinyl or wood siding, stucco and brick.
Because custom angles and curves are easily created, it's simple to build in bows, bays and radiuses.
ICF systems accommodate any of today's most popular design features, such as tall walls, large openings, long floor spans, and cathedral ceilings.
Internationally Proven & Code-Accepted
Originally developed in Canada (where concrete home building is standard), ICF systems have been used successfully around the world for more than 40 years. Tens of thousands of ICF homes have been built in recent years throughout the United States and Canada. They have proven successful in every region and climate, from Orlando to Calgary. ICF systems are accepted by all the major model codes in the U.S. and by the National Building Codes in Canada. ICF systems are also accepted in New Zealand and Australia
Fast To Learn & Easy To Use
Although it looks new and different, anyone with construction experience can quickly get up to speed with ICFs. An ideal crew has a mix of concrete placement and carpentry experience. Once the crew has some practice, each ICF-built home requires less skilled labour and less total labour than a wood-framed home. ICFs are very lightweight, so crews stay fresh through the day. Likewise, ICFs present no problem for the sub-contractors who come after the walls are poured. Since holes, chases and rectangles are easily cut into ICFs with a knife or saw, installation of mechanical systems is a snap. The fastening of drywall and lap siding is just as fast and easy. And mid-course corrections, such as moving an opening, are no big deal - just saw it out and re-form. It isn’t more difficult to make changes to an ICF wall - it's just different.
Over the last ten years, concrete prices have been remarkably stable. Recent price increases in other materials have generated interest in concrete building systems as never before. Labour savings and readily available materials make ICFs, feature for feature, one of the most cost competitive wall systems in New Zealand. ICF construction costs the same as and often less than other forms of construction.
