External Heating Insulation - Primary Pro - 22mm / 28mm wall sleeve 1m

Protect external insulated pipework properly with the Primary Pro 22mm / 28mm Wall Sleeve (1m).

Purpose-built for sleeving 22mm and 28mm Primary Pro insulated heating pipes cleanly through external walls. Designed specifically for heat pump and external heating applications, this wall sleeve prevents damage from debris, cement acids, mortar, and moisture ingress, helping maintain the integrity and lifespan of your insulation system.

Unlike standard plastic sleeves that are often too tight or oversized, the Primary Pro sleeve is correctly sized for 22mm and 28mm insulated pipe runs, giving installers a cleaner finish and a more professional through-wall solution.

 The 1 metre length can be easily cut to suit site requirements, making it ideal for air source heat pump primary pipework, external flow and return lines, and renewable heating installs.

For the best weatherproof finish, pair with Primary Pro Bond & Seal and sealing rings to create a fully sealed wall penetration that helps reduce heat loss and keeps moisture out.
