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.

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.
