Topdek is a single-ply Insulated roof deck system. Topdek is factory pre-engineered single fix membrane deck system for applications on flat, pitched or curved roofs.

Insulation Core

• Loss Prevention Certification Board (LPCB) certified
• Zero ODP and non-deleterious

Performance

Fire
Property & Business Risk Protection - Loss Prevention Certification Board (LPCB) certified external cladding systems are classed as 'non-combustible building'by the Association of British Insurers (ABI).
The panels are rated FAB/SAB as per BS476 Part 3.

U - Thermal transmittance W/m²K
l - Long-term Thermal conductivity W/mK

Insulation Continuity
Topdek is factory pre-engineered to guarantee total insulation continuity.

Airtightness

Sustainability and Energy Efficiency
Topdek provides Parts L2A, L2B & J thermal performance, insulation continuity and airtightness certainty, allowing downsizing of M&E plant, which in turn reduces energy usage and carbon dioxide (CO2) emissions by up to 40% per annum, over the buildings lifetime.

Acoustics
Topdek panels have a single figure weighted sound reduction Rw = 23dB.

Sound Reduction Index (SRI)

Frequency Hz	SRI dB
125	17.9
250	18.1
500	17.4
1k	23.2
2k	30.4
4k	40.3

Biological
Topdek panels are immune to attack from mould, fungi, mildew and vermin. No urea formaldehyde is used in the construction, and the panels are non-deleterious.

Guarantees & Warranties

Ward will provide product warranties and guarantees on an individual project basis.

Standard Packing - Road Haulage

Topdek panels are stacked weather sheet to weather sheet (to minimise pack height). The top, bottom, sides and ends are protected with foam and timber packing and the entire pack is protective wrapped.

The number of panels in each pack depends on panel thickness, as shown in the table. Typical pack height is 1100mm.

Panel Core Thickness	No. Panels/ Pack (max)
80	8
100	6

Delivery

All deliveries are by road transport (unless indicated otherwise) to project site. Off loading is the responsibility of the cladding contractor or installer.

Sea Freight
Ward provide a sea freight despatch service.

Site Installation Methods

Site assembly methods and instructions are available from the Ward Technical Services Department.

Training for contractors is necessary and is available from Ward.

Applications

Flat and Pitched Roofs
Topdek can be used on building applications with a minimum roof pitch of 1:80 (0.72°) to avoid ponding.

Curved Roofs
For curved and inverted curve roofs with radi greater than 70 metres.
