font-size: 14px;\"\u003eStandard closed-cell foam lagging degrades under UV exposure — it becomes brittle, cracks, and absorbs moisture. Wet insulation conducts heat rather than retaining it, directly reducing the heat pump's COP and SCOP. It has no integral weatherproof coating, so moisture enters through cuts, joints, and clip holes. For external ASHP pipework exposed to UK weather across a 10-15 year installation lifetime, standard foam lagging is not appropriate. Primary Pro's factory-applied UV-stable waterproof coating addresses all of these failure modes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eIs Primary Pro Part L compliant?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eYes. Primary Pro insulation meets the Part L Building Regulations requirements for external ASHP pipe insulation and is MCS-compatible. The 19mm wall thickness on 28mm, 35mm, and 42mm bore, and 25mm on 22mm bore, satisfy the external heating pipework requirements. The Bond and Seal sealed system — including the wall penetration — is required for full Part L compliance; unsealed or partial insulation does not satisfy the standard.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eDo I need to insulate the connection at the heat pump unit itself?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eYes — and this is one of the most commonly missed steps. The insulation-to-heat pump casing connection must be sealed with Bond and Seal. The heat pump generates vibration during operation and any unsealed gap will open over time, allowing moisture to track inside the insulation. Bond and Seal remains flexible when cured and accommodates vibration without cracking.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eHow often does Primary Pro insulation need to be maintained?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eInspect during the annual heat pump service. If the outer surface shows wear, discolouration, or cracking, apply Primary Pro Maintenance Coat to restore the protective finish. Testing has shown that installations not in direct south-facing sunlight may not require recoating within the first five years. Bond and Seal joints at the wall penetration and heat pump connection should also be checked and touched up if any gap or shrinkage is visible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 16px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eCan Primary Pro be used alongside Intaflex pre-insulated flexible pipes?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eYes — Primary Pro was developed in direct collaboration with Intatec, the manufacturer of Intaflex. The pre-made valve jackets (AS32, AS33, AS52, AS53) are purpose-designed for Intatec external valves used on Intaflex installations. Bond and Seal is suitable for sealing the junction between Intaflex and Primary Pro rigid insulation, and for sealing to the heat pump casing. Primary Pro rigid insulation is used for copper pipe sections of the same installation, giving a consistent appearance and protection standard throughout.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #008377CF; color: #fff; padding: 16px 20px; border-radius: 4px; margin-top: 32px; font-size: 14px; line-height: 1.9;\"\u003e\n\u003cstrong\u003eRelated Products:\u003c\/strong\u003e\u003cbr\u003ePrimaryPro 100x Pre-Made Insulation Jacket (Trade Bulk Pack) | PrimaryPro 50x Pre-Made Insulation Jacket (Trade Bulk Pack) | Condensate Pro Pipe Insulation 35mm x 13mm (IG001) | Condensate Pro Termination Kit (CPTERMKIT) | Primary Pro Bond and Seal 290ml (AS001)\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Primary Pro","offers":[{"title":"22mm x 25mm x 1m","offer_id":63825669488989,"sku":"AS45","price":430.0,"currency_code":"GBP","in_stock":true},{"title":"28mm x 19mm x 1m","offer_id":63825669521757,"sku":"AS022","price":530.0,"currency_code":"GBP","in_stock":false},{"title":"35mm x 19mm x 1m","offer_id":63825669554525,"sku":"AS033","price":465.0,"currency_code":"GBP","in_stock":false},{"title":"42mm x 19mm x 1m","offer_id":63825669587293,"sku":"AS042","price":159.0,"currency_code":"GBP","in_stock":false},{"title":"42mm x 19mm x 500mm","offer_id":63825669620061,"sku":"AS043","price":159.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/PrimaryProHeatPumpPipeInsulation.webp?v=1773339963","url":"https:\/\/qualityheating.co.uk\/products\/primary-pro-heat-pump-pipe-insulation-external-ashp-insulation-system","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
