• For use on any pitched or flat roofs.
• Suits all common pipe diameters and pitch.
• One size slate will seal pipes of diameter between 25mm and 125mm.
• Suitable for flue pipes at temperature up to 100°C.
• Lead Flexislates provide a weather-tight joint where flue pipes and soil stacks penetrate a slate, tile, asphalt, felt or lead covered roof.

The flexibility of lead allows the slate base to be dressed to tiles of all profiles, avoiding wind lift or chatter problems.

Premium Flexislate bases are cut from BS EN 12588 Code 4 rolled lead sheet.

The Neoprene conical upstand is vulcanised at elevated temperature and pressure in contact with the base, forming a very strong rubber-metal bond.

Two conical upstand profiles are available, flat for 0°-30° roof pitched for 20°- 40° roof pitches.

Premium Flexislates are able to operate satisfactorily at temperatures between -40°C and 100°C and have an expected life of greater than 20 years, if correctly installed.

Premium Flexislates are also available in aluminium.

ADVICE ON USE

1. Select a lead Flexislate with an upstand angle suitable to the pitch of the roof. If fitting over the boiler flue, ensure that the outer wall of the flue pipe in contact with the slate does not exceed a constant 100°C.
2. The upper surface of the rubber sleeve has a pattern of concentric grooves that should be used as knife guides. Select a groove diameter that is slightly smaller than the required diameter, to ensure a weather-tight fit. Take care to not cut across the grooves.
3. Use liquid soap to lubricate the neck of the rubber sleeve of the Flexislate prior to fitting.
4. Always apply a coat of Prepat or Patination Oil to all exposed lead surfaces, as well as the underside of the leading edge. Take care that the Patination Oil does not come into contact with the rubber sleeve.
5. Fit over the pipe and on a pitched roof, finish the top edge of the tile with a welt.
