The benefits of a roof system approach to tiling and slating

What is the difference between single and double camber plain clay tiles?
The key difference between single camber and double camber clay tiles is their shape. Single camber tiles are curved in one direction - on the long edge. Double camber tiles are curved in two directions from top to bottom (like single camber tiles), and also from left to right. This is also known as longitudinal and latitudinal camber.
These differences have different implications in terms of aesthetics, applications, desi...

Heat stress in dairy cows
Well-ventilated cow housing and adequate levels of natural light in buildings are key elements to ensuring the continued productivity of housed cows during the hot, summer months.
Traditionally, letting natural light into cow housing is achieved by installing fibre glass panels and low level GRPs in the roof of a building. Whilst these components help to increase light levels within cow housing, they have the adverse effect of focusing the heat from the sun in certain ...

Specifying non-slip decking for roof gardens
Specifying decking for roof gardens usually means there will be several competing requirements, including space restraints, slip risk, accessibility, aesthetics, maintenance and performance.
In residential applications, roof decking is a popular way to make economical use of space in increasingly tight urban environments. It is also used in raised walkways and balconies to provide inclusive shared spaces in apartments and student accommodation.

Non-slip decking considerations for marina, moorings, piers and jetties
Decking is often specified for marinas, moorings, piers and jetties, all of which are typically wet environments where timber can be slippery. Therefore specifying for these areas must take into account the high risk, with antislip performance and safety being key considerations for designers.
What material is best for decking in marine environments?
The different materials that can be used for decking for marinas and moori...
What to consider when specifying non-slip decking for accessible high-traffic stairs and ramps
When specifying decking in high-traffic public areas such as stairs and ramps, certain criteria should be addressed to ensure the space is accessible for all users.
There can be concerns that the castellations of traditional anti-slip decking could make the surface uneven and uncomfortable for wheelchair users. The high level of grip provided could make the change in surface difficult for some pedestr...

What are the fixing requirements of BS 5534?
As we previously discussed, BS 5534 is the revised British Standard for slating and tiling for pitched roofs and vertical tiling, which came into effect on the 31st August 2014.
Fixing specifications are one of the main elements that have changed in this updated standard.
Due to the adoption of Eurocodes for the calculation of wind loads, specifications have been upgraded to ensure roof coverings are fixed more securely. When it comes to roof tiles a...
