Soaker Sheet

8 products

Soaker sheets weatherproof the roof around a roof mounted ventilation terminal on profiled metal and cladding roofs. Each SKR soaker sheet is a two piece, post moulded GRP sheet around 2mm thick, with a 150mm upstand that the terminal sits over and a gel coat finish in Goosewing Grey (BS 00 A 05) as standard. It fits into the roof sheeting around the opening so rain runs around the terminal rather than into the building. We supply them to suit Systemair RAW and RAV roof terminals from 200/250mm to 1000mm, made to order in around 2 to 3 weeks, in any BS or RAL colour and flanged if needed. For sizing help, roof profile matching or trade pricing, email hello@efans.co.uk or call 0161 399 3825.

Frequently asked questions

What is a soaker sheet?

A soaker sheet is a moulded panel that fits into the roof sheeting where a roof terminal or roof fan passes through. Its raised upstand surrounds the opening and the terminal fits over it, so water is shed around the penetration rather than into it.

Which soaker sheet fits my roof terminal?

Choose the soaker sheet with the same size reference as your Systemair RAW or RAV terminal: SKR 200/250, 300/315, 350, 400/450, 500/560, 630/710, 800 or 1000. The aperture runs from around 450mm square on the SKR 200/250 to around 1365mm on the SKR 1000.

How big are the sheets?

The SKR 200/250 to SKR 800 are around 1800mm long and the SKR 1000 around 2000mm long, all with a 150mm upstand. They weigh around 10kg (15kg for the SKR 800 and 20kg for the SKR 1000).

Will it match my roof profile?

Soaker sheets are made to suit standard profiled roof sheets. Tell us the make and profile of your roof sheets when you order so the sheet is moulded to match.

What colours are available?

The standard finish is Goosewing Grey (BS 00 A 05), the same as the RAW roof terminals. Any BS or RAL colour is available to order, and sheets can be supplied flanged.

How long does delivery take?

Soaker sheets are made to order with a lead time of around 2 to 3 weeks. Contact us before ordering if you are working to a programme.

Do I need a purlin box as well?

Usually, yes. The soaker sheet weatherproofs the roof and the purlin box carries the weight of the terminal into the roof structure. We can quote the RAW roof cowl, purlin box and soaker sheet together: email hello@efans.co.uk or call 0161 399 3825.
