Importance of Airtightness Insulation Performance (thermal)

1m 14 cm

1m

without gap: R-Value 3.3 W/m2K

experimental conditions inside temperature +20°C outside temperature -10°C Pressure difference 20 Pa = wind force 2-3 Measurement: Institute of building physics, Stuttgart Source: DBZ Dec-1989, page 1639ff

with 1mm gap: R-Value 0.7 W/m2K

Performance down by 4.8 !
