What is Hilti CF-I XTW used for?
Insulating window and door joints, and sealing, insulating and filling generally. Hilti also lists acoustic insulation work: shutter boxes, cooling and heating lines, wood floors, insulation panels, and air conditioning and ventilation channels.
How cold can you apply Hilti CF-I XTW?
Down to -15 °C, and up to 35 °C. Hilti's CF 812 WD starts at 5 °C and its CF-AS CJP at 0 °C, so this is the can for a winter site. Cured, it holds from -40 to 80 °C.
How fast does Hilti CF-I XTW cure?
Tack free in about 10 minutes at 74 °F and 50% relative humidity, and cuttable in about 25 minutes at 23 °C and the same humidity.
How much does one can of Hilti CF-I XTW fill?
Up to 1.9 cubic feet, the largest yield of the three Hilti foams Cranco carries. Call the branch to confirm the can size available today.
Does Hilti CF-I XTW give volumetric control?
Cranco's catalogue says precise dispensing and volumetric control, and that the foam is more reliable over a wide temperature range. On a window joint that matters, because an over-filled bead is the one that bows the frame.
Is Hilti CF-I XTW a fireblock foam?
Hilti publishes no fireblock standard or approval for CF-I XTW. For a residential fireblock listing, CF-AS CJP carries one and this foam does not.
