Adhesive systems use bonding mortars and secondary mechanical fixings. This is the typical EWI type system and is best suited to sound masonry backgrounds.

Adhesive Starter Track

1. DPC membrane
2. ProRend EIFS starter track
3. Fixings at 600mm centres

Starter Track Mitre Corner

1. Mitre corner
2. Fixing 50mm from inside corner

Insulation Application

1. 100% coverage of insulation panel using 10mm groove tiling trowel
2. Insulation panels installed block bond
3. Minimum stagger 150mm
4. Mechanical fixings 10/m² in each corner of panel and centre

Aperture Planning

1. Minimum 150mm stagger of insulant joints
2. Avoid vertical or horizontal joints at corners of apertures
3. Cut insulation panels to fit around aperture corners
4. Ensure suitable quantity of mechanical fixings used around aperture

Corner Detail

1. Ensure alternating blockbond at corner

Reveal Detail

1. Insulation panels fitted around aperture to avoid horizontal and vertical joins at corners
2. Face insulation panels fitted 20mm proud of blockwork at aperture
3. 20mm insulation fillet fitted between face insulation and window frame to avoid cold bridge
4. Joins in insulation fillet not coincident with joins in face insulation panels
5. Adhesive bitumen sealtape fitted between insulation fillet and window frame to ensure watertight

Ventilation Services, Flue Pipe And Fixing Pattresses

1. Fixing pattress made of 10mm render carrier board with insulation or solid timber
2. Maximum dimensions: 300mm x 300mm
3. Thickness of pattress to thickness of insulation
4. Mechanically fixed back to substrate
5. Avoid primary insulation joints within 150mm of fixing pattress

Ventilation Service

1. Ventilation services fitted through centre of insulation panel without joints

Avoid ventilation service at edge of insulation panel

1. Hot flue requires mineral fibre insulation (if primary insulant is EPS) around hot flue pipe
2. Hot flue fitted through centre of insulation panel without joint
3. For systems using EPS as primary insulant minimum distance of EPS from hot flue to be determined during system design
4. Avoid hot flue at edge of insulation panel

Fire Barrier In EPS Systems

1. Mineral Wool Lamella insulation fitted at floor level between EPS insulation panels
2. Fire Barrier panels fitted block bond so joins alternate with EPS joins - minimum 150mm stagger
3. Adhesive mortar used to rear of fire barrier panels - see figure 3
4. Mechanical fixings used to secondary fix fire barrier panels to substrate
