Hi Manstir,

We understand that Twin-Wall was spoiled by workmanship error. We tried hard to provide a proper installation technique.

As mention by a few user here, It's lower in cost and Best Insulation compares to Solid Polycarbonate.
Furthermore, we will promote 5 wall soon in Malaysia, which reduce even more Heat in this hot weather.

I would suggest you to find an Experience Contractor to do this.
Examples of a good project is Petaling Street and  Kota Kemuning, Columbia Hospital

If you need guide, Please PM me or email ( sabic.sfs@gmail.com) , and we will be happy to email you the Installation Method.
