DuPont's Tyvek® Supro Plus
Tyvek* Supro Plus BBA certificate: 08/4548
As Tyvek* Supro but with integral adhesive lap tape for use in the "Tyvek* sealed roof system".
Sealing all horizontal laps will contribute to the system's thermal efficiency by reducing air infiltration.
Tyvek® products are compatible with most building materials. Conveniently sized rolls are lightweight and easy to handle. No need to install vents - just lay the membrane, batten and tile, that’s it
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.

Tyvek* roofing applications can be broken down into two main categories:
1. SUPPORTED APPLICATIONS
2. UNSUPPORTED APPLICATIONS
The application category will determine which membrane is suitable and how it is to be installed.
1. SUPPORTED APPLICATIONS
Tyvek® Supro - Tyvek® Supro Plus
This is where the Tyvek* membrane is laid directly over a supporting layer such as timber boarding or flexible/rigid insulation. In this condition counter battens over the membrane will be required to lift the tiling battens off the membrane and create an effective drainage path to the eaves.
Scottish boarded roofs
Are also categorized as supported applications but battens are normally omitted and the slates are nailed directly through the membrane and into the boarding. Recommended grade: Tyvek* Supro.
Sealed Roof System
The supported application gives the end-user the option to upgrade the system to a sealed roof by taping all laps and penetrations in the membrane. Tyvek* Supro Plus is most suitable for this purpose as an integral sealing tape is provided.
2. UNSUPPORTED APPLICATIONS
Tyvek® Supro - Tyvek® Supro Plus Over rafters (the traditional method)
The Tyvek* membrane is laid over rafters and allowed to drape slightly for drainage beneath tiling battens. To accommodate the drape an airspace of approx 10mm beneath the membrane will be required. In order to prevent the risk of wind uplift a maximum drape of 10mm in the membrane is recommended. No counter battens will be required over the membrane in this application. Recommended grade: Tyvek* Supro.
Over counter battens
Tyvek* can also be draped over counter battens that are installed over timber boarding or rigid insulation. This represents the most practicable approach to on-site membrane installation and corresponds with the majority of rigid insulation manufacturers recommendations. Recommended grade: Tyvek* Supro.
Sealed Roof System -
Tyvek* can also be installed over rafters in a taut condition with counter battens fixed over. This method is normally adopted when a sealed system is specified. Tyvek* Supro Plus is most suitable for this purpose as an integral sealing tape is provided.
Guidelines
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 mm Vertical centres = max 300 mm
Overlathe 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 sharking
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
