Looking for Plant Room, Substation or Façade Louvres?
Residential louvre windows are strictly designed for domestic HDB/condo toilets and service yards. For data centres, SP Group substations, cooling towers, and M&E plant rooms requiring certified BS EN 13030 Class A rain defense, high aerodynamic airflow, and ASTM E90 acoustic attenuation (up to 31 dB), view our engineered Performance Louvres.
Do I need an HDB permit to replace my windows?
Yes, a renovation permit is mandatory. As an HDB-licensed contractor, we will submit the permit application on your behalf.
Can I DIY my window replacement?
No. By law, all window replacements must be done by a BCA-approved window contractor to ensure public safety.
How much road noise does it cut?
Significantly reduces noise with our standard 6mm toughened glass and acoustic gasket. Thicker glass is available for heavy-traffic locations.
Can I get a site measurement before confirming?
Yes, but a measurement fee applies. This fee is fully refunded when you confirm your order.
Will it stop rain leaks?
Yes. Every window ships with a weather gasket and is pressure-tested at our factory before delivery.
Is it HDB approved?
Yes. We are an HDB-licensed window contractor and submit the paperwork for you.
