Life of the building and durability using CFS framework?
Expected life span of 100 years or so whilst durability is subject to “abuse by user”
Waterproofing and patches on walls?
The method / material used and workmanship takes care of these issues.
External and internal finishes?
Treatment using “stucco”, tiles, stones, paints etc works well on the cladding and have cleaner lines than brick walls.
Hollow sound and sound transfer in wall structures?
Filling the cavity with Rockwool Insulation or CLC takes care of the STC , above the codes. Floor ‘heel sound’ transfer can be treated with usage of acoustic lining on floor before tiling.
Insulation leading to energy savings?
The infill material and has a substantial improvement over the brick wall.
Door and window finishes?
Better due to accuracy of openings.
USPs and weaknesses for DRY WALL Constructions?
Time factor and increase of carpet area being USP, whilst weakness is that designs need to be frozen before starting detailing and execution.
CFS framework construction more expensive than RCC construction?
Under present market prices, the direct construction costs are at PAR, but CFS could lead to a higher ratio of Carpet to built-up area. The Financial interest burden of RCC construction because of time factor greatly reduces in CFS framework construction.
