Structural RoofDek acoustic structural liner tray

RoofDek acoustic structural liner tray

RoofDek acoustic structural liner trays provide a neat planar inner surface and structurally support the external envelope.

RoofDek acoustic structural liner trays offer a wider flat soffit enabling a greater perforated area, achieving the best acoustic absorption result.

The percentage of exposed area is the open area divided by the exposed area of steel following around the profiles. The percentage of cover area is the open area divided by the plan area of the soffit.

We maintain a friendly technical help desk which is freely available to all architects, engineers and contractors to assist with all aspects of RoofDek and liner tray design. The services we offer include:

Specification service - Our RoofDek team are able to provide a comprehensive specification service. Assistance in creating NBS specifications for RoofDek and trays can be provided to ensure the correct deck or tray is specified for the right application.

Design calculations & diaphragm design - To assist the specifier, the team are able to provide design calculations for live, dead, wind and snow drift loads and where required diaphragm design calculations.

Sound absorption and reduction - RoofDek perforated decking provides excellent sound absorption characteristics, our technical team can provide details of systems tested for both absorption and reduction. We also offer indicative acoustic calculations on differing build ups.

Roof Safety - Our technical department can provide details of non fragility performance of the RoofDek itself and the use of fall prevention and fall arrest systems on RoofDek roofs.

Inhouse CPD seminars - Primarily aimed at engineers and architects, these free seminars last around 50 minutes, ending with a question & answer session and are delivered by our experienced regional teams.

Topics include:

  • Structural roof deck in construction
  • Composite floor deck in construction
  • Sustainable steel cladding refurbishment solutions
