Building Process of the Insulated Concrete Form
Insulated Concrete Form or ICF is a system of formwork for reinforced concrete that stays in
place as a permanent interior and exterior substrate for walls, floors, and roofs. It is now used
for commercial and high performance residential construction as new building codes are
adopted by most home builders. It usually consists of a molded expanded polysterene (EPS)
shell, which are bonded together with concrete to form a solid foundation. Unlike the
conventional insulated masonry wall, insulated concrete form has about R - 25 insulation values
that gives prevents heat loss during winter and heat gain during summer.
Building insulated concrete form is less daunting because of its modularity. To see how
insulated concrete wall is made, let us discuss the building process.
Insulated concrete form makes solid and sturdy, energy efficient and extremely durable walls.
The insulated concrete walls are made from 15% concrete which is composed of Portland
cement, thereby making it super strong. Some manufacturers use fly ash as an alternative for
Portland cement nowadays.
Insulated walls are constructed from the corners to the middle to form one row at a time. To
minimize waste, the end blocks are cut to fit the planned dimension. Blocks are staggered as
the wall rises to avoid weak polysterene formwork due to long vertical seams. Bucks or
structure frames are put around the openings to make attachment points for windows and
doors and also to boost the opening's strength.
Depending on what type of insulated concrete form, the interior and exterior finishes and
facades are affixed directly to the tie- ends. The surfaces of the interior insulated concrete form
polysterene wall must be covered with a drywall panel or other wall coatings to prevent it from
being wet. But for the first month after the completion of the house, interior humidity is
common since the concrete cures and can damage the drywall. To resolve the interior humidity,
general contractors used small residential humidifiers or building's air conditioning.
The exterior foam insulation of a modular home should not be easily damaged by groundwater
leakage, insects or rodents. And to answer this issue, manufacturers make insecticide- treated
foam blocks and install drainage sheeting, drain tiles and waterproofing techniques to eliminate
water inside the home.
The construction of insulated concrete form is not insensitive to the price of materials and
labor. Initial costs may be higher than the conventional home building process. Generally, the
cost of making an insulated concrete can add 3-5 % of overall construction.
