Insulation

1. Cold Rooms & Drafts

• Missing or compressed insulation
• Gaps around windows, doors and service penetrations
• Uneven temperatures between rooms

2. Condensation & Mould

• Cold spots cause moisture to settle
• Black mould forms on walls and around windows
• Damages decoration and affects health

3. High Heating Bills

• Heat escapes through walls, roof and floor
• Boiler runs longer to maintain temperature
• Poor EPC rating affects property value

minor Repairs

• Top up loft insulation to current standards
• Seal gaps around windows, doors and lofthatches
• Add reflective foil behind radiators on cold walls

moderate Repairs

• Replace wet or mouldy insulation
• Improve ventilation to prevent condensation
• Install cavity wall insulation by injection

major Repairs

• Install internal or external solid wall insulation
• Upgrade floor insulation during full floor renewal
• Whole-house retrofit including airtightness layer

When Replacement Is Needed

• Renovating walls, lofts or floors anyway
• Persistent condensation or mould issues
• Energy efficiency upgrade for sale or rental

Installation Steps

1. 1

   Survey

   • Identify cold spots with thermal imaging
   • Check existing insulation condition
2. 2

   Choose System

   • Mineral wool, PIR, EPS, sheep's wool or wood fibre
   • Match to wall, roof or floor build-up
3. 3

   Install Before Closing Up

   • Fit insulation before plasterboard or floor decking
   • Avoid compressing material
4. 4

   Vapour Control

   • Add vapour barriers on the warm side
   • Seal joints and penetrations
5. 5

   Ventilation

   • Install trickle vents or MVHR
   • Prevent interstitial condensation
