ICF Supplies Ltd


ICF supplies was founded in 2012 by our managing director, who at the time ran an architectural practice. He was so impressed by the Nudura system, along with the thermal performances achieved, that he became a distributor. Working out of our Basildon headquarters we have quickly grown to be the largest supplier of insulated concrete forms (ICF) in the country. Being inherently airtight, our system makes this aspect of the build much more straightforward to achieve and with the concrete core as the structural element, once achieved this will not be lost through building movement over time. We have a comprehensive range of PHPP Psi value certificates. The heart of the Nudura design is providing very thermally efficient housing by means of very effective insulation encapsulating the thermal mass. We not only supply Nudura ICF but crucially provide training and hands on practical assistance on site to ensure that our products are used correctly and appropriately throughout the process.
