Arxx. The ICFs manufacturer now offers reFIT, a basement finishing system that provides for a finished wall assembly R-value of 13.9. The expanded polystyrene panels interlock vertically and install easily using metal base track, corner panel connectors, and wall clips and shims; embedded fastening strips allow for attachment of drywall. The panels are resistant to mold, mildew, and rot, says the maker. 800.293.3210. www.refiticf.com. More
Quad-Lock Building Systems' Extra Pane is designed to provide insulation value to concrete walls up to R-84. More

IntegraSpec. The companys panelized (knock-down) system features bi-directional and reversible components to ease installation and reduce cutting, dust, and waste. An embedded insert accepts interlocking webs (spacers) to create core widths from 4 to 12 inches, with H clips to combine spacers for wider core dimensions. Inserts also help mitigate form lift during the pour and provide 1 5/8-inch-wide nailing strips that are marked on both sides of each panel. Standard assembled wall sections (blocks) measure 48 inches long by 12 1/4 inches high. 800.382.9102. www.integraspec.com. More
Fox Blocks. Preassembled interlocking blocks are offered in 4-, 6-, 8-, and 12-inch core thicknesses and measure 16 inches tall. Blocks, including corners, are designed to be reversible to speed construction and reduce on-site cuts, foam dust, and waste. Accessories include 45-degree angles, taper tops, T-blocks, and corbel ledges. The system can achieve STC ratings of up to 50 and is designed to meet seismic and high-wind codes. Plastic ties and forms are recyclable and blocks emit no VOCs, says the maker. 877.369.2562. www.foxblocks.com. More
ARXX. A trio of ICF systems include knock-down and preassembled interlocking blocks to create walls between 4 and 24 inches thick and 60 feet high. The systems offer two- to four-hour fire resistance based on core thickness, a noise rating of STC 50 or higher, and resistance to F5 tornado winds. The ARXX Prime system (shown) is available with a 6-, 8-, or 10-inch core width and features an exposed web design (furring strips) on both faces for attachment of finish claddings. The products include recycled content and emit no VOCs. 800.293.3210. www.arxx.com. More
Owens Corning. The Fold-Form system of preassembled interlocking blocks enable walls from 4 to 16 inches thick. Universal Corner Kits and hardware/accessory packages allow for faster and complete installations and a wide variety of shapes, including curved walls, brick ledges, and offsets. The system offers resistance to 250-mph winds, achieves up to an STC-52 sound resistance rating, and offers 67% less air infiltration than a typical wood-framed building, says the firm. 800.438.7465. www.foldform.com.
