Tyvek Supro and Tyvek Supro Plus from Dupont

Tyvek Supro

Tyvek Breather Membranes leading manufacturer of air and vapour building control layers

DuPont Tyvek is the household name when it comes to vapour permeable roofing underlay.

Tyvek Supro is an extremely water-resistant, airtight and vapour open membrane. The installation of Tyvek Supro in roofs is extremely efficient, and the results are very effective, cutting energy consumption, heating bills, and greenhouse gas emissions to the atmosphere.

Tyvek Supro is an extremely water resistant, airtight and vapour permeable membrane providing superior air and 0moisture management for commercial and residential buildings. It is a multi-purpose, durable and reinforced Tyvek grade for use in all supported and unsupported pitched roof applications, including warm, hybrid and cold roofs. Also suitable for Scottish sarking board systems and low pitched metal roofs as well as wall and floor applications.

Tyvek Supro Plus

DuPont Tyvek Supro rafter level building control membrane. Also ideal for walls and floors

Supro Plus is a breather membrane with Integral Adhesive Lap Tape

Through the use of its unique and highly advanced technological material, Tyvek. manufactures products that protect the environment for future generations.

Supro Plus in roofs is, again, extremely efficient - cutting energy consumption, heating bills and greenhouse gas emissions to the atmosphere.

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 improved by specifying Supro Plus.

Product Applications

Tyvek Supro is an extremely robust air and vapour control membrane designed for pitched roof rafter level applications. It also offers exceptional performance in walls an floors.

Note: Supro plus has the added benefit of an integrated adhesive tape towards one side edge, absolving the need to apply double sided adhesive tape


Product Characteristics

Tyvek Supro products are vapour permeable and manufactured by spinning strands of high-density polyethylene (PE-HD) and bonding them together with heat and pressure to form a flexible sheet.

They are available with an integral adhesive tape (Tyvek Supro Plus)  or without (Tyvek Supro) in which case a butyl adhesive tape should be used.

Product Attributes

When used as a Roof Tile Underlay, Tyvek must be installed and fixed in accordance with the BBA Certificate No. 08/4548
Installation can be carried out under all conditions normal to roofing work.
The product is installed with the printed side uppermost and lapped to shed water out and down the slope.
Overlaps must be provided with the minimum dimensions given in the table below
In closed eaves constructions, eaves guards should be used to protect the product from sunlight and direct water into the gutter. Tyvek Eaves Carrier is recommended by the manufacturer for this purpose.
Hips should be covered with a 600 mm wide strip of the product.

Weather-tightness

Tests indicate that the product will resist the passage of water, wind-blown snow and dust into the interior of a building, under all conditions to be found in a roof constructed in accordance with the relevant clauses of BS 5534 : 2003.
The product resists penetration of liquid water and consequently may be used as temporary waterproofing prior to the installation of slates or tiles. The period of such use should, however, be kept to a minimum.

Risk of condensation

For design purposes, the product’s water vapour resistance may be taken as not more than 0.25 MNsg–1 and for roofs designed in accordance with BS 5534 : 2003 or BS 5250 : 2002, Section 8.4, it may be regarded as a Type LR membrane.
In common with all roofs, care must be taken in the overall design and installation to minimise the risk of water vapour coming into contact with cold parts of the construction. Factors to be considered and minimised include, moisture diffusion through the ceiling, infiltration through unsealed openings/penetrations in the ceiling and services evaporating or venting moisture into cold spaces.
The risk of condensation is highest in new-build construction during the first heating period, where there is high moisture loading due to wet trades, such as in-situ cast concrete slabs or plaster.
The risk of condensation diminishes as the building naturally dries out. See BBA Information Bulletin No 1 — Roof Tile Underlays in Cold Roofs during the Drying-out Period. Ceiling and insulation horizontal (cold ventilated roof)
Roofs designed and constructed in accordance with BS 5250 : 2002 will adequately limit the risk of interstitial condensation.

Ceiling and insulation inclined (warm roof)

For roofs with an insulated inclined ceiling, ventilation above or below the underlay will not be required provided that the passage of moisture by diffusion and by convection is controlled, eg, by a vapour control layer or a continuous envelope of insulation with a high vapour resistance. Ceiling and insulation partially inclined (warm roof and cold roof)
Where an insulated ceiling only spans part of the roof-line, resulting cold roof spaces should be installed.

Wind loading

Project design wind speeds should be determined and wind uplift forces calculated, in accordance with BS 6399-2 : 1997.
The product, when fully supported, has adequate resistance to wind uplift forces. 7.3 For a cold ventilated system, wind loading on the underlay should be calculated in accordance with BS 5534 : 2003, Section 5.5.2.7. For acceptable wind loads with specific batten spacings for the draped product, using a 25 mm deep tiling batten (see section 16, Table for Physical properties — general).

Strength

The product will resist the loads associated with installation of the roof (See BBA Certificate Section 16, Table for Physical properties — directional).

Properties in relation to fire

The product will melt and shrink away from heat, but will burn in the presence of a naked flame. The product is classified in accordance with BS EN 13501-1 : 2007 as a Class E material.
When the product is used unsupported, there is a risk that fire can spread if it is accidentally ignited during maintenance works, eg by a roofer’s or plumber’s torch. As with all types of underlay, care should be taken during building and maintenance to avoid the material becoming ignited.
When the product is used in a fully supported situation, the reaction to fire will be determined by the support.

Maintenance

As the product is confined within a roof structure and has suitable durability maintenance is not required.

Durability

The product will be virtually unaffected by the normal conditions found in a roof space and will have a life comparable with that of traditional roof tile underlays, provided they are not exposed to sunlight for long periods (see section 12.4). Advice regarding exposure can be obtained from the Certificate holder. Installation


Tyvek Supro / Supro Plus - Product Installation Tyvek Supro and Tyvek Supro Plus from Dupont laid horizontally

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

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.


Tyvek Supro Plus laid horizontalyScottish 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.


Fully supported

Tyvek Supro and Tyvek Supro Plus from Dupont overlaps at RidgeThe product may be used over sarking boards of softwood (cold ventilated roofs), and either with continuous insulation or insulation placed between the rafters (warm roofs).

The product is either secured to the support with counter battens at least 12 mm thick to create a drainage and vapour dispersal space between the product and the tiles.

Or, when using timber sarking, the traditional Scottish practice with the tiles or slates fixed directly into the boards.

This space should be ventilated in accordance with BS 5250 : 2002 when using tight fitting roof covering.

Counter battens, when used are fixed with corrosion-resistant staples or galvanized clout nails as appropriate.

Tiling battens are secured to the counter battens and support fixings.

Alternatively, the membrane may be installed draped over counter battens, with sufficient drape to allow drainage of liquid water under the tiling battens.

Care must be taken to minimise the risk of interstitial condensation as described in section 6.5 particularly for timber sarking which may be below the dew-point for extended periods during winter months.


Unsupported Tyvek Supro and Tyvek Supro Plus from Dupont penetrations installation

The product, when installed as an unsupported system, is fixed in the traditional method for roof tile underlays, ie draped between the rafters.

Repair

Damage to the product can be repaired easily prior to the installation of slates or tiles by replacing the damaged areas, by patching and sealing correctly. Care should be taken to ensure that the water-tightness of the roof is maintained.

Finishing

Detailing of abutments, verges and hips must be in accordance with the Certificate holder’s instructions.

The tiling and slating must be carried out in accordance with the relevant clauses of BS 5534 : 2003, BS 8000-6 : 1990 and the tile/slate manufacturer’s instructions, especially when using tightly-jointed slates or tiles.
