	== Description ==		=== Description ===

	Roofing with Guna Tubes is a variation of the vault and is achieved by substituting the standard material used to execute the curve, instead of voussoir type masonry. This method is unique since an element called ‘guna tube’ is used which consists of tapering conical, burnt clay pipes adapting them to come together, socket into one another and stacked in a curved form along the centering formwork. A series of such arches make a barrel vault capable of withstanding considerable loads. The top of the roof is given a plaster finish. After joints are filled and topped with plaster, the roof becomes rigid and waterproof, doing totally without steel or timber. Air inside the hollow-tiled roof protects from heat and cold. It is fabricated and ready for use within three days and requires no maintenance having a life span of more than fifty years. Being light in weight this variation of the vault roof is safe even in earthquake prone areas.

	A series of arches made out of the guna tile make a barrel vault capable of withstanding considerable loads – upto 1 ton/m2. The top of the roof is given a plaster finish. After joints are filled and topped with plaster, the roof becomes rigid and waterproof, doing totally without steel or timber. The cost of this roof works out to Rs. 20/sq.ft. It has the following advantages: • Air inside the hollow-tiled roof protects from heat and cold. A 10o temperature difference is observed in slab roof and guna vault roof. • It has no under structure, yet can bear weight of 1000 kg/m2. • It is fabricated and ready for use within 3 days. • Requires no maintenance and has life span of more than 50 years. • It is not affected by rain, hail or wind. • Being light in weight (less than 12 kg/sq.ft). the vault roof is safe even in earthquakes. • Even if the mud walls collapse, the roof remains intact residing on pillars and beams. After construction of brick pillars, ring beams and gable walls, the M.S. trusses are placed in position above the opposite pillars held with guy ropes and timber poles. Now GI pipes (12 mm dia., 10 nos.) are placed on the trusses in the MS rings provided at specific points. They are supported by gable walls at both ends. Guna pipes are now laid dry on this skeleton shuttering in a plug-socket manner, completing the roof ring by ring. Lime/cement mortar is now poured on the roof, trowelling it into the gaps and leaving the top rough to receive the finishing coat. Care is taken to remove the skeleton support within 12 hours to allow natural setting.

 Echo and reverberation can be limited by acoustic correctors. These correctors are called single resonator absorbers. A German engineer, Helmholtz, elaborated some formulas to calculate them. The human voice ranges from 100 Hz to 2 kHz, with an average frequency at 400Hz. Correctors of various sizes can be installed to absorb the desired frequencies. <br>
