| Prendos, in conjunction with other industry partners, is developing risk analysis tools for weather-tightness. This pilot study involved 250 residential units on 50 sites. The median value of the units is $450,000?not a cheap housing problem. The average age is 4.3 years confirming this is an emerging issue. Building height is significant with the average being 2.4 storeys but wind load is suspected to be less important than many in the industry thought. Wall leaks dominate but roof edge and balcony leaks are major contributors. As can be seen, window-related leaks are the main contributor to wall leaks. All 39 sites that had balconies experienced balcony leaks with handrails being the major contributor. This study helps to confirm the need for the whole industry to tackle this problem as stated in the recent preliminary findings of the Building Industry Authority overview group. Prendos assisted this group on its recent visit to Auckland and will continue to co-operate with industry to find solutions to this problem. | ||||
