Flexx Block

Flexx-Block is the ultra energy efficient wall with system over 3 times less air infiltration then traditional wooden stud walls. Typically, wood stud walls allow on the average of 10 air changes per hour compared to Flexx-Block’s 3 air changes per hour. This means thermal loss through the walls is all but eliminated. The only heat and air infiltration is through the doors, windows and venting at the soffit to allow the roof to breath, (See Picture) this along with the thermal mass of the concrete core, keep temperatures more consistent, with less temperature swings, and hold the temperature longer than traditional wood stud walls.

Buildings constructed with FlexxBlock ICF walls are significantly safer then buildings constructed with other building materials. Flexx-Block walls have the strength to withstand 200 mph winds making them the only choice for building in hurricane or tornado prone areas.

Flexx-Block buildings promote healthier environments with the potential for mold growth significantly reduced. No air infiltration means controlled and consistent indoor air quality. EPS foam is made by using steam to expand polystyrene beads so there is no off gassing of materials due to the use of chemicals during the manufacturing process.

Flexx-Block ICF walls are 4 to 8 times quieter than traditional building walls. They have a STC Rating of 52 as compared to traditional masonry which has a STC rating of just 27.

Finally, Flex-Block ICF are cost effective. Construction costs are more than offset by energy savings. It costs between 4 and 7% more to build your home with Flexx-Block Insulated Concrete Forms. If the cost of a 3000 sf wood framed home is $360,000.00 and the cost to build it with Flexx-Block ICF walls was 5% more, it would cost an additional $18,000.00 to build your house. At a 5% interest rate, 10% down payment and a conventional 30 year mortgage, the increase in your monthly payment would be $85.89. If your energy savings was 40%, that would amount to $1,680.00 per year. You would also save $270.00 per year on insurance. The net mouthy savings would be $75.16. That’s $890.00 per year or $26,700.00 over the length of the mortgage. This example does not take into account that utility costs will most likely increase, which will increase your savings and cost effective.
