Introduction SpanoTech

Airtightness Vapour control layer Fire protection Acoustic protection EWP products WF insulation


Solutions SpanoTech

Thermal performance Insulation

Ventilation Airtightness

A gap as small as 1mm in the vapour barrier can reduce the U-value by a factor of 4.8 Measurement carried out by: Institut Fur Bauphysik, Stuttgart

Crucial for energy efficiency Moisture transfer causes structural damage Air quality Membranes & panels


Wood based panels in TF buildings Airtightness

Floors, walls, ceiling : 31%!!!

Ducts

Fireplace

Plumbing penetrations

Doors

Windows

Fans & vents

Electric outlets


Key air leakage points Airtightness

Passive house standard n50 <0.6 1/h

Achieved in TF by interior air barrier system

Panels (tape) & membranes

Sites OSB too air permeable, failure certification

KU Leuven 8 ≠ brands OSB West-Europe

Large variation, OSB passive houses questionable

Solution / repair very expensive (priming, membrane, …)
