EVEREST Yellow Cement Roofing Sheets

Yellow Cement Sheets generally refer to flat, rigid panels made from a mixture of cement, fibers, and sometimes other materials. They come in various types, each with specific characteristics and applications. These sheets are commonly used in construction for roofing, siding, and cladding. These are rigid sheets made from cement and other additives. They are commonly used as a substrate for tile and stone installations in both interior and exterior applications. Yellow Cement Sheets come with added pigments to provide a specific color. These can be used for aesthetic purposes in roofing or siding applications.

ISI Specification

Sizing

For Roof:

• Let us assume the slope length is L metres
• To cover this length, a minimum of N number of sheets are; where N = L - 0.200/2.8 (a whole number)
• Maximum lap loss is M metre Where M = (N-1) x 0.200
• Maximum sheet length required is P; where P = L + M => L + (N-1) x 0.200 (rounded off to next digit divisible by 0.25)
• Once P is obtained, sizing should be done keeping the number of sheets at N
• Check if the slope can be covered by (P - 0.25)
• Check that the number of purlins does not exceed - K; where K = L - ( a1 + a2) / 1.40 + 1 (a whole number); where a1 = distance between the eaves purling and the eaves edge in - Metre; where a2 = distance between the eaves purling and the eaves edge in - Metre.

For Wall Cladding : Most economical length is 1.75 M, which allows a rail spacing of 1.6 M.

Estimating

For both roof and wall cladding, the number of sheets in a particular row N = L - 0.04 / 1.01 (a whole number); where L = length of the shed in metres.
