Tyvek® Supro Plus

Tyvek® Supro With Integral Adhesive Lap Tape

A Tyvek® non-ventilated pitched roof system will help to minimise the risk of condensation, but air infiltration and convective heat losses can also be reduced.

This can be achieved by sealing all laps, penetrations and around the perimeter of a Tyvek® membrane with adhesive tape.

In addition to controlling condensation, the overall energy efficiency of a non-ventilated pitched roof system can be further improved by specifying Tyvek® Supro Plus.

Guidlines

Tyvek is laid horizontally over the entire roof surface, parallel with the eaves and secured with non-ferrous felt nails or staples as follows:

 

 

 

 

 

 

 

 

 

 

Horizontal centres = max 600 mmVertical centres = max 300 mm

Overlap the Tyvek® sheeting by 15 cm.

Laying unsupported

Lay the Tyvek underlay directly over timber members, pull it taut to create a minimal drape.

Laying supported

Lay the Tyvek underlay directly onto timber boarding or insulation and fix timber counter battens over.

Scottish sarking

Lay the Tyvek underlay directly onto open-jointed timber boarding and fix with galvanised clout nails. Lay the slates over the Tyvek underlay in direct contact.

The overlap at the ridge should be at least 300 mm.

 

 

 

 

 

 

 

 

 

 

 

Overlaps, pipe penetrations, roof window junctions and other details can be further secured with Tyvek Tape.

Connections to other surfaces eg. masonry should be made with Tyvek Butyl Tape.

Any damage that occurs in Tyvek® should be repaired using Tyvek® Tape.
