Primary Pro Sleeve for 35mm Primary Pro Insulation (PS035)
It is really important to sleeve insulated pipework through the walls to protect them from debris & acids in the cement, moisture and rodent damage. In the past this has been a real issue, as off the shelf plastic pipework is either too small or too large. The Primary Pro solution was to make Primary Pro Sleeves for the job!
Primary Pro Sleeve (PS035) has a 90mm external diameter and is designed to fit 35mm Primary Pro Insulation (AS033). We sell a 91mm diamond core cutter to fit the PS035 sleeves here (91mm Diamond Core Bit for 35mm Primary Pro Sleeve (DC91)).
Primary Pro Sleeves can be fitted and sealed using the patented Bond & Seal to prevent heat loss and moisture ingress.
