Hilltop Products ltd
Why we love it
  • Precise and time-efficient cuts.
  • Perfect for loft insulation.
  • Battery-operated for easy mobility.
Main Highlights
  • Cutting PIR boards is a known challenge across the globe, often being time-consuming and quite labour-intensive as it is often performed with a hand saw or a Stanley knife. With the all new Cold Cutting Insulation Wire we hope to see this become a thing of the past. Offering precise cuts and being the most time-efficient method we are proud to introduce our Insulation Wire Cutter.
  • Used for Rock wool, Foamed Polyurethane plates, Foamed glass board, Foamed EPS, PIR Boards such as Kingspan/Celotex and even Foamed Rubber
  • Perfect for Loft & Shed insulation cutting
  • Double support surface with inclination option
  • Vertical wire allows cutting of 650 mm long and 270 mm thick
  • Some claim that a hot wire tool can be used to cut PIR boards, but this is incorrect. Products made from PIR and PUR materials are not suitable for hot wire cutting, as attempting to do so would release unpleasant fumes.
  • The Cold Cut Insulation Cutter is a Brushless motor machine, allowing for a much longer run duration with more freedom due to its battery operation, allowing you to quickly move from site to site with it, reducing labour time spent sawing away at some of the more challenging foam boards.
