Proper insulation of cathedral ceilings will allow ceiling temperatures to remain closer to room temperatures, providing an even temperature distribution throughout the house. Cathedral ceilings must provide space between the roof deck and home’s ceiling for adequate insulation and ventilation. This will be achieved through the use of truss joists, scissor truss framing, or sufficiently large rafters........................................................................................................................................15Exterior Wall Insulation....................................................................................................................15Foundation Insulation........................................................................................................................16Slab-On-Grade Insulation..................................................................................................................16Conclusion.................................................................................................................................................173
Introduction Wood frame housing may be built in various design and specifications depending on whether standard design will be used or in other instances where a custom design is created, and always in any instances building code provision and good design principles must be observed to provide a stable and durable house, in order to maximize occupants’ health, comfort and safety and reduce building environmental footprint.Each design should always provide easy access for people of diverse physical capabilities and adapt to occupants changing needs through; i)Structural design Where the design of wind is earthquake are always considered, in order to ensure all factor of safety are included.ii)Five safeties Safety under fire involves combination many factors, some of which can be minimized by building requirements, and others that can only be controlled by the occupants, with several measures that are supposed to be considered.Ensure that there is limitation in the area of unprotected openings in buildings close to property lines to reduce the chance of a fire spreading from one house to another.Ensuring that there is required smoke alarms on every floor and in sleeping areasEnsuring that we set minimum door and exit route widths and required window egress routes from bedrooms in order to help occupants escape in the event of fire. Ensuring that we provide clearances around heating and cooking appliances to prevent fires from starting. Occupants to minimize exposure to fire risks by maintaining smoke alarms are in working conditions.Occupants to minimize exposure to fire risks by exercising care when using cooking and heating appliances.iii)Space between houses iv)Sound control Provincial of materials used in the floor and assemblies by reducing flanking paths so that noise is not transferred around assembling v)Room height Minimum ceiling height is 2.1 m (6ft 11 in)4
