Conical Clay Tile Vault Roof

The Vaulted Roof, in general, is characterized by its upward slope, often surpassing the typical 8 to 10 feet height of standard flat ceilings/roofs. Favoured in modern architectural designs, vaulted roofs enhance natural lighting and adapt seamlessly to various designs.

The specific design of the conical clay tile vault roof utilizes hollow conical clay tiles to create the vaulted structure. Arranged in a series of arches over a ring beam and supported by brick pillars, these hollow conical clay tiles interlock in a plug-socket fashion, laid dry on a foundational framework, and progress ring by ring until the roof is complete. This assembly of arches makes a barrel vault capable of withstanding substantial loads of up to 1 ton/m2. An external layer of plaster binds the arches, and a meticulous application of lime/cement mortar fills the gaps. This is carefully trowelled, ensuring a coarse top surface to facilitate the finishing coat. The supporting framework is carefully removed within 12 hours, allowing the structure to set naturally. Once plastered, the roof solidifies without needing steel or timber reinforcements. Finally, an overlay of "broken China tile" pieces not only renders the roof waterproof but effectively reflects sunlight, ensuring interiors remain pleasantly cool and consistently insulated.

Key advantages:

Pioneered by the Centre of Science for Villages located in Wardha, Maharashtra state, India, this innovative roofing technique is rapidly gaining attention for its strength and visual appeal. A team proficient in these techniques can construct up to twenty houses (ten twin houses) in just 45 days. Steps are demonstrated in the following videos -
