BH With Common Problems But With Nearly Same Design !!!
After my talk at Kuala Trengganu, I have been talking to a number of BH owners who claimed to have problems with their BHs.
One was complaining that his Banker wanted to shut him down if he do not settle all the loan borrowed after having his BH up for 3 years.
Another person claimed that after 6 years his BH nests number ended at 150 nests.
One peculiar thing about both was their BHs.
When I received their BH pictures and have this strange feeling that both looks more of less the same design and finishing (external).
The contractor left the external walls (top two floors) with being plastered.
This is either a coincident or the same contractor (consultant).
One of the owner claimed that the bricks were left without any plaster due to cooling effect.
Something like the surface areas exposed to those air are larger as compared to getting them plastered.
Hmm something to digest and think if it true.
One clear thing is that the walls were with one layer of bricks.
I have a very strong feeling that if these two BHs are with only one layer the nesting rooms will be unbearable.
The room temperature will be very high.
I need to check this issue when I carry out a visit to one of the BH.
Usually when the room temperature hit above 30*C (33-35*) those permanent tenants will abandoned the house.
Without proper heat shield these two BHs will face a grim future.
The chances of getting more nests will be slim.
What can be done?
There are many options.
The best is to insulate the BH walls from the inside. This will be much easier and cheaper.
The second method is to apply those cement plaster and put a layer of heat shield paint. This will be pretty expensive and laborious.
The third option is to erect another wall on the external wall using those cladded zinc. This will also be pretty expensive and time consuming.
I might try to recommend the first option and the most critical part will be the top most floor.
The total cost will be subjected to the size of the walls, the cost of heat shield materials. wood frames, the cement boards and labor.
The cost will be at least RM 3.50 (estimated) per square foot.
If the BH is with 25'X70' X 8', we will have a total of 1520 square feet per floor.
If we multiply with RM 3.5 = RM 5,320.
The above cost is without the labor cost.
I would think this will be the cheapest option.
Will probably check the house temperature first before making the possible recommendations.
