Low Pitch Performance


The 20/20 is not only cost effective it will also perform down a minimum pitch of 15°. Manufactured from natural alluvial clay, using the latest ceramic technology, the 20/20 is a high performance interlocking clay tile that has been designed to withstand extreme weather conditions. Following extensive wind tunnel testing the minimum pitch of the 20/20 has now been lowered from 22.5° to 15° degrees at 100mm headlap

Product - 20/20


Lower costs, cut completion times and reduce CO2 with the innovative 20/20 Interlocking clay plain tile
The 20/20 is a New Generation clay tile that makes a clay plain tile roof more affordable through an innovative design that will reduce labour and material costs, and cut completion times.
These benefits also translate into a significant reduction of CO2 emitted per roof because CO2 emissions are proportional to the tonnage of clay extracted, processed, dried and fired. The design of the 20/20 means less material is used compared to traditional plain tiles and therefore a corresponding saving in the CO2 emitted per roof is achieved. In addition choosing 20/20 cuts the number of battens required per m2 of roof area by 60% further reducing the use of materials and lorry movements.
When this reduction is combined with Sandtoft's use of 100% green electricity, 20/20 has the capacity to reduce the carbon footprint of a roof by a massive 50%.

Low Pitch Performance
The 20/20 is not only cost effective it will also perform down a minimum pitch of 15°. Manufactured from natural alluvial clay, using the latest ceramic technology, the 20/20 is a high performance interlocking clay tile that has been designed to withstand extreme weather conditions. Following extensive wind tunnel testing the minimum pitch of the 20/20 has now been lowered from 22.5° to 15° degrees at 100mm headlap (see technical data)
This low pitch performance means that the 20/20 provides the perfect solution for low pitch extension work. It is now possible to complement clay plain tile roofs (which have a minimum pitch of 35°) with a natural roof covering on the low pitch elevations. The 20/20 is also available in a natural slate colour (Antique Slate) which enables it to complement natural slate roofs.
  • Now performs at pitches down to 15°
  • Groundbreaking 'open gauge' design
  • More cost effective than all traditional plain tiles
  • Saves materials, weight and transport
  • Saves 50% CO2 compared with traditional clay plain tiles
  • Uses only 20.5 tiles per m²
  • Natural alluvial Humber clay
  • Made to ISO 14001 environmental standard

Due to natural drying and firing shrinkage in the manufacturing process small variations in size can occur, therefore it is advisable not to mix tiles of different colours on the roof. Please contact Technical Services for further guidance.

For projects where the rafters are below the minumum recommended roof pitch, please contact our Technical Services for advice
Rafter length restrictions apply at minimum roof pitch.
Concealed 20/20 ventilators must not be used on roof pitches below 22.5°.
Note that the miniumum recommended roof pitch for concealed tile vents is 22.5°. However, we will shortly be introducing a low profile cowl ventilator into our range suitable for use at 15°.
