Marley Concrete interlocking ' Modern Tiles '

[graann]

Can anyone tell me if these tiles have a minimum guage ?
I can find nothing on their website.
If I intend to use a dry verge system for these tiles , what should the maximum overhang be ? 50mm ?
Are they easy to cut or best buy the 1/2 and 3/4 tiles available ?
What suitable ridge tiles for a roof with 25 degree pitch ?

Thanks
Graham

Notes The effectiveness of the tile or slate to operate at the minimum recommended pitch and lap may be influenced by special circumstances. Guidance on pitch and lap should be obtained from the Technical Advisory Service for the following:
• Interlocking tiles and slates where the roof slope exceeds 6 metres in length and/or the site is rated to be in a severe exposure category.
• Double-lap fibre cement slates where the roof slope exceeds 6 metres in length (severe/very severe exposure) and 9 metres in length (sheltered/moderate exposure).

The Modern interlocking tile is a flat, smooth, single-lap interlocking design with a slate-like appearance enhanced by a broken bond laying pattern.

All of our concrete interlocking tiles can achieve an 'A+' rating (the lowest environmental impact) in the Building Research Establishment's Green Guide to Specification (* element ref: 812410007, 812410018, 812410049).

Accreditation to the BES 6001 framework standard for 'Responsible Sourcing' means that projects using our concrete tiles can now achieve extra credits under BREEAM and The Code for Sustainable Homes. Click here to find out more.

Thanks for your reply however I have read the information you have sent several times today but can not find the minimum guage.
Thanks for your help , it is appreciated

Heavy batons those Alistair

 

[noseall]

All the info is there if you read it properly although Alistairs word spacing is a bit confusing to say the least.

You can have a headlap of anything between 75mm and 100mm.

This would mean a batten gauge of between 345mm (75mm headlap) and 320mm (100mm headlap).

Your first tile batten should be positioned so that you have a minimum of 50mm overhang into the gutter. This can easily be set by crudely dummying up a short batten and a tile and a tape measure.

 

[Alastairreid]

From setting your 1st batten measure up to 30mm/40mm from ridge and divide by your required guage.

You cannot close the guage up too much as the tiles will start kicking up.

I copy/pasted that data dunno why it came out like that ..Sorted.

Thanks for helping me out so quickly.
It is appreciated.

 

[noseall]

For dry verge to work properly you must stick to the batten spacing parameters. Closing down any more than the max headlap of 100mm will cause problems.

Thanks for that , you have been very helpful.
