Rail Starter Track

Ventilated Starter Track

1. DPC membrane
2. ProRend EIFS ventilated starter track
3. Fixings at 600mm centres into sheathing board

Termination Profile and Packing Shims

1. PVCu termination profile sits on Ventilated Starter Track
2. Packing shims create typical 15mm cavity
3. PVCu termination profile fixed through sheathing board into steel uprights
4. Use of laser beam to confirm straight application of rails

Insulation Application

1. Insulation panels fitted with rebated groove embedded on PVCu termination profile
2. PVCu intermediate track fitted into rebated groove of insulation panel
3. Vertical PVCu T spline between every insulation panel clips into PVCu termination profile below
4. PVCu intermediate track packed off substrate in line with laser cavity
5. Mechanical fixing into every vertical upright

Insulation Application Continued

1. Repeat figure 14 with additional intermediate tracks
2. Insulation panels installed block bond with minimum 150mm stagger

Aperture Planning

Insulation Layout Around Apertures

1. Minimum distance of aperture from insulation panel joint 150mm
2. Avoid vertical or horizontal joins at corners of apertures
3. Cut insulation panels to fit around aperture corners
4. Minimum distance of aperture from insulation panel join 150mm

Corner Detail

Insulation Corner Detail

1. Ensure alternating block bond at corner

Reveal Detail

Rail Reveal Detail

1. Insulation panels fitted around aperture to avoid horizontal and vertical joins at corners
2. Face insulation panels fitted 20mm back from window frame
3. 20mm insulation fillet fitted to end of insulation panels closing rail cavity
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

Fixing Pattress

1. Fixing pattress made of solid timber with groove rebate for PVCu intermediate tracks
2. Dimensions: 500mm x 500mm
3. Thickness of pattress to thickness of insulation + cavity
4. Fit cavity flashing tape above pattress to ensure moisture drips continue down cavity

Ventilation Service

1. Ventilation services fitted through edge of insulation panel with vertical join at centre
2. Ventilation service must avoid intermediate rail tracks
3. PVCu T splines to be cut to appropriate length by installer

Figure 21 - Hot Flue

1. Hot flue requires mineral fibre insulation (if primary insulant is EPS) around hot flue pipe
2. Hot flue fitted through edge of insulation panel with vertical join at centre
3. For systems using EPS as primary insulant minimum distance of EPS from hot flue to be determined during system design
4. Hot flue must avoid intermediate rail tracks
5. PVCu T splines to be cut to appropriate length by installer

Fire Barrier In EPS Systems

Figure 22 - EPS Rail Fire Barrier 1

1. Mechanically fix stainless steel fire track to substrate above final row of EPS insulation
2. Stainless steel fire track contains ventilation and drainage holes in cavity section
3. Mechanically fix intumscent strip to substrate above stainless steel fire track

Figure 23 - EPS Rail Fire Barrier 2

1. Install coarse of Mineral Wool Rail Slab
2. Further mechanically fix with stainless steel fire track above insulation
3. Use vertical PVCu T spline to fix insulation between stainless steel fire tracks

Figure 24 - EPS Rail Fire Barrier 3

1. Continue installation of EPS rail system above fire barrier using PVCu intermediate tracks
