The Complete Insulation Aftercare Guide


Investing in insulation for your home or business is a crucial step towards improving energy efficiency, comfort, and reducing environmental impact. But the journey doesn’t end after insulation. Just like any other aspect of your property, proper aftercare is essential to ensure your insulation continues to perform optimally for years to come. But how do you do it the right way? 

In this guide, we’ll explore the appropriate aftercare for various types of insulation. Whether you're a seasoned professional or a DIY enthusiast, understanding how to maintain different insulation materials is crucial for maximising their benefits. So, let’s find out how to make sure your insulation investment pays off in the long run.  

Plasterboard Insulation: 

Plasterboard insulation, such as our KNAUF SOUND SHIELD PLUS, is a versatile option commonly used in walls and ceilings to improve thermal and acoustic properties. After installation, it's crucial to: 

  • Monitor Moisture Levels:  Regularly check for signs of dampness or leaks, especially in areas prone to humidity, such as bathrooms and kitchens. Address any moisture issues promptly to prevent mould growth and maintain insulation effectiveness. Our KNAUF MOISTURE PANEL is specially formulated for use in high humidity areas, ensuring high performance and durability even in challenging environments.  
  • Ensure Proper Ventilation: Proper airflow is essential to prevent moisture buildup behind the plasterboard. Ensure vents are unobstructed and consider installing extractor fans in high-humidity areas to improve ventilation. 
  • Inspect for Damage: Periodically inspect the plasterboard for cracks, holes, or damage. Repair any issues promptly to maintain the integrity of the insulation barrier and prevent heat loss. 

Multifoil Insulation: 

Multifoil insulation offers superior thermal performance and is suitable for various applications, including roofs, walls, and floors. To maximise its efficiency for multifoil insulation, such as Superfoil SFTV and Superfoil SF19+, consider the following aftercare measures: 

  • Seal Seams and Overlaps: Ensure all seams and overlaps are securely sealed to prevent heat loss. Use foil tape or adhesive to seal any gaps or tears in the insulation barrier. 
  • Check for Punctures: Regularly inspect the insulation for punctures or tears, especially in high-traffic areas or areas exposed to the elements. Patch any damage promptly to maintain thermal performance. 
  • Protect from Moisture: Multifoil insulation is susceptible to moisture damage, which can reduce its effectiveness. Ensure proper waterproofing measures are in place, especially in areas prone to water ingress. 

Mineral Wool Insulation: 

Mineral wool insulation, like our Rockwool Flexi Slab and KNAUF Omnifit Insulation Roll, offers excellent thermal and acoustic properties and is commonly used in cavity walls, lofts, and floors. To care for mineral wool insulation, consider the following tips: 

  • Prevent Compression: Avoid compressing mineral wool insulation during installation, as this can reduce its effectiveness. Ensure it is installed snugly but not tightly packed to maintain its loft and thermal performance. 
  • Monitor for Settling: Periodically check for signs of settling or compression, especially in areas with heavy foot traffic or weight-bearing loads. Add additional insulation as needed to maintain desired thermal levels. 
  • Maintain Ventilation: Proper ventilation is essential to prevent moisture buildup, which can compromise the insulation's effectiveness and promote mould growth. Ensure vents are unobstructed and consider installing breathable membranes in high-moisture areas. 

PIR Insulation Boards: 

PIR insulation boards provide high thermal efficiency and are commonly used in walls, floors, and roofs. To care for PIR insulation boards, including our 90mm PIR T&G Cavity Wall Sheet Full Fill, consider the following aftercare tips: 

  • Seal Joints and Edges: Ensure all joints and edges are tightly sealed to prevent air leakage and maintain thermal performance. Use appropriate sealants or adhesives to seal any gaps or cracks in the insulation barrier. 
  • Inspect for Damage: Regularly inspect the insulation boards for signs of damage, such as cracks, dents, or delamination. Address any issues promptly to prevent heat loss and maintain insulation effectiveness. 
  • Protect from Moisture: PIR insulation boards are vulnerable to moisture damage, which can compromise their thermal performance. Ensure proper waterproofing measures are in place, especially in areas prone to water ingress. 

Fire Protection Insulation: 

Fire protection insulation, like our Tyvek FireCurb Housewrap Breather Membrane, provides both thermal and fire protection and is essential for building safety. To properly care for fire protection insulation, consider the following aftercare measures: 

  • Follow Installation Guidelines: Proper installation according to manufacturer guidelines is crucial to ensure the insulation's effectiveness in containing fire spread. Follow recommended installation practices and consult with a professional if unsure. 
  • Regular Inspections: Periodically inspect the insulation for signs of damage, wear, or tear. Pay particular attention to areas exposed to high heat or mechanical stress, as these may compromise fire protection. 
  • Address Issues Promptly: If any damage or deterioration is detected during inspections, address the issues promptly to maintain the integrity of the fire barrier and ensure the safety of occupants. 

In conclusion, proper aftercare is not just about maintaining your insulation; it's about safeguarding your home's comfort, energy efficiency, and structural integrity. By investing time and effort into the upkeep of your insulation, you're ensuring an entire range of benefits for your property.
