SolarMasters is the manufacturer of ProFormICF. Insulating Concrete Forms (ICFs) represent the superior way to build. ProFormICF is simpler and easier to install than wood-frame methods � and even other ICF systems. It�s faster, taking less time with fewer people. And it�s better, because ProFormICF buildings are vastly more energy-efficient. Stronger. Quieter. Resistant to fire, moisture, mold and the elements. With a positive ecological impact. This state-of-the-art method of construction is also the simplest. ProFormICF insulating concrete forms are EPS (expanded polystyrene) blocks that easily stack together to create walls of virtually any configuration. The tubes inside the block are filled with concrete that cures and hardens into a monolithic, reinforced core of incredible strength. ProFormICF gives you unlimited design flexibility. Got a saw? ProFormICF cuts easily into any shape you need � perfect for unique window openings and arches. You can also choose from our pre-formed corners in varying sizes and angles. And any exterior or interior finish can be directly applied to the blocks. The ProFormICF system is easy to learn, requiring less time for training. Installing window and door openings is fast and simple. ICF blocks are stacked together fast � and the job is done sooner. Only one construction crew is needed to get the job done, instead of the typical three. This is the better way to build, period. Energy savings generated by ProFormICF walls, which carry a R45 energy rating, are enormous � and continue for the life of the building. You save on utility and maintenance costs. ProFormICF buildings stand strong against the wind and weather and will not warp over time. They can have up to a four-hour Fire Resistive Rating. And many companies give discounts to ICF building owners for disaster and fire insurance.
