How much does it cost to replace all windows in a terrace house in Penang?

A full window replacement package for a double-storey Penang terrace house typically costs RM 14,000-22,000 installed, covering 6 bedrooms, the living hall, kitchen, and two sliding back doors. Single-storey packages run RM 9,000-14,000. Package pricing saves 10-20% versus ordering window-by-window.

What is the difference between Series 55, 66, and 88 aluminium?

Series 55, 66, and 88 refer to aluminium profile thickness. Series 55 is the entry-level standard for sheltered low-rise units. Series 66 and 88 use thicker profiles with better weather sealing, worth the 30-40% premium for northwest-facing facades, upper-floor units, and coastal-belt properties in Tanjung Bungah or Batu Ferringhi.

Do I need laminated glass for my windows in Penang?

Under the Uniform Building By-Laws 1984, laminated glass is required for openings above 2m from finished floor level. For standard ground-floor windows this is not mandatory, but upgrading to 6mm laminated glass adds protection against breakage and reduces solar heat gain in west-facing rooms.

How long does aluminium window replacement take?

A full terrace house window replacement typically takes 2-4 days for a professional team. Single-window replacements take half a day. Heritage lime-plaster walls in older George Town shophouses may add 1-2 days for re-plastering around removed frames.
