Exemplar PMMA System

This tough membrane provides a resilient long lasting barrier to water penetration. The flexibility of the system easily accommodates surface movement and it is resistant to occasional foot traffic and UV degradation. It is suited to large or small projects on both warm and cold roofs. It is cold applied and rapidly becomes weather resistant, providing high levels of UV protection.

The system can withstand maintenance foot traffic and is available with a slip resistant finish that is suitable for light maintenance foot traffic, although this does not eliminate all risk of slipping. This is particularly relevant in the event of ice forming on the roof surface.

Hyflex Exemplar PMMA is a fully bonded system. Resistance to wind uplift is adequate to meet the effects of wind suction likely to occur in practice. Indicative tests also show that the system achieves EXT FAA rating (to BS 476-3).

Hyflex Exemplar PMMA is fully backed by a 10 year manufacturer s guarantee. All work is carried out by a network of fully accredited contractors.

Substrates:

The system can be applied to a variety of roof surfaces, including built-up felt, concrete, asphalt and PVC single-ply. The system can also be used in conjunction with a new timber deck, which allows the product to be used for applications such as new build, deck replacement, or warm roof upgrades. It is effective on complex areas such as valley gutters, extraction units, coping stones and parapet walls. In most cases there is no stripping of the old roof, therefore the system is ideal for projects that require a fast solution with minimum disruption.

Application:

Do not lay when the temperature is below 5 C or above 30 C. Allow primer to dry for at least 2 4 hours before overcoating. Ensure 50 mm side and end laps of reinforcement.

Surface protection:

If regular foot traffic is a requirement, please consult Hyflex for advice on additional surface protection or details of the specialist balcony/ walkway systems.
