Nathan chats with his friend Dave who runs and owns Condensate Pro and now Primary Pro. Primary Pro is a polyethylene product which comes pre painted making it easier to use than class O insulation. He has also developed Bond & Seal which can be applied all weathers unlike the contact adhesive which is used for Class O. The conversation is a useful resource for people wanting to understand the types of pipe insulation available and how to install it correctly, especially for heat pump pipework which is outside Topics  weather resistance and weather proofing are discussed along with UV protection.polyethylene and Class ONitrate Rubber FoamClosed cell insulationClipping insulation VISIT A HEAT PUMP WITH NESTA check out this new initiative Acknowledgements: Thank you to all the podcast listeners.
