Primary Pro is the go-to choice for professional heat-pump installers when insulating and sealing external system pipework. 

About Primary Pro

Designed with installers in mind, Primary Pro insulation and accessories are 100% weather-proof, UV-resistant, and compliant with Part L / MCS standards. The brand develops practical products such as insulation jackets for antifreeze valves, easy-fix back plates, sealing tools and clips — all aimed at sealing external pipework to maximise heat pump efficiency. 

Key Features & Benefits

• Weather & UV Proof: the external insulation is UV-resistant out of the box, so you don’t need to repaint on site.

• Easy Installation: components like insulation jackets and seal kits are built with installer-friendly fit and maintenance in mind.
• Maintained Finish: includes maintenance-coat products so that annual servicing leaves the finish looking good, not weathered.
