One-way and privacy film for corridor-facing glass

Corridor-facing bedrooms are the usual Singapore reason for this search. In a point block or a slab block the common corridor passes the window. A lower floor feels it more, because people walk past at eye level. One-way film, also called one-way mirror film, makes the outside look reflective while the outside is brighter than the room. That is an optical balance, not a guarantee we print as a percentage. At night, with the bedroom light on and the corridor dim, people outside can see in again. If that reversal is unacceptable, frosted film is the honest product.

HDB’s guideline is the same sentence as on the heat page, and it bites harder here. Film over existing window or balcony-door glass needs no renovation permit when it is non-reflective or not above 20% reflectance. A film whose whole point is to look like a mirror can be the film the guideline tells you not to use. We will not install a highly reflective roll and call it compliant. Send the corridor photo and the room photo in daylight. A condo MCST cares about the elevation from the driveway and the opposite block. A mirror bedroom in a facade of clear glass is often refused. Ask the management office before the roll is cut. Landed street-facing glass has no HDB cap, and a neighbour’s sightline is still a reason to choose frosted if night privacy matters.

Privacy film is not a child-safety lock. A restrictor that stops a casement opening fully is the child-safety page, and no restrictor price is published there either. Reflective glass does not stop a fall. It is also not cat mesh. The pet-proofing page prices no-drill cat mesh at S$120 to S$220 a window so a cat cannot fall. That mesh is visible. It is not a one-way mirror. Do not ask for both products under one invented package.

Service-yard glass and bathroom top-hung windows are usually the frosted job, because the yard faces the next block’s yard and the bathroom needs cover after dark. A one-way film on a louver is a poor fit: the blades move, the film cracks at the fold, and the sightline remains through the gaps. Say if the opening is a louver, a casement or a sliding panel. Sliding balcony doors are glass too. Film on that glass follows the same HDB sentence. Replacing the door is not this visit.

Heat and glare can be a side effect of a darker reflective film, and they are not the reason to ignore the 20% line. If the room is west-facing and the corridor is not the problem, start on the heat-rejection page and the west-facing guide. If the stay is rusty, neither film goes on. The approved window contractor does the stay. Interior reseal at S$180 to S$380 remains the rain job, not a privacy product.

Homey Furnishing Pte. Ltd. (ACRA UEN 202018148K), 27 Mandai Estate, #06-10 Innovation Place, Singapore 729931, invoices permit-exempt window work done from inside the flat. V On Construction Pte. Ltd. (ACRA UEN 201611708H), on the HDB Directory of Renovation Contractors, invoices an HDB renovation permit when the window scope needs one. The exterior rivets, friction stays, rollers and glass are done by a BCA approved window contractor registered under workhead RW01. Homey Furnishing is not that RW01 contractor.

Curtains, blinds and roller shades are not part of this booking. Fabric is a different product, and these pages do not quote it.

Look from inside the room. Do not lean out to test a stay or a pane.

1. Photograph the window from inside and from the corridor in daylight.
2. Say whether night privacy matters.
3. Do not order a mirror roll before the 20% question is answered.
4. If the opening is a bathroom or a service yard, read the frosted page.
5. Stop if the stay is loose.

Film on existing glass is the HDB line that usually needs no permit. The reflectance cap and the MCST elevation are the parts people miss.

How you're charged

A window job that already has a sentence on HomeySG uses that sentence. Nothing in this table is a fuel surcharge, and the hour is not added on top of a band unless the written scope says so.

Who is allowed to touch the window

HDB’s window-works guidelines require a BCA approved window contractor listed in HDB’s directory for installation and replacement, and an HDB renovation permit before that work starts. BCA registers that contractor under workhead RW01. Retrofitting replaces aluminium rivets in variable-geometry stays with type 304 stainless steel. Homey Furnishing does not issue that rivet.

• Interior silicone or PU reseal, at S$180 to S$380 a window, is the exempt interior job on the window repair page.
• A handle at S$60 to S$120 is that published row. A failed stay or rivet is not a handle.
• Film on intact glass is not a sash replacement. On an HDB flat, film over existing window or balcony-door glass does not need a permit when it is non-reflective or not above 20% reflectance.
• Service-yard and balcony parapet grilles need a permit. Flats handed over from 1 July 2007 use HDB’s approved grille designs. Older blocks may take an internal grille that does not protrude, without that permit.
• A condo facade is the MCST’s elevation. Reflective film, a grille and an external screen are uniformity questions before anyone sticks or drills.
• Curtains, blinds and roller shades are not quoted here.
• Nobody leans out of the casement. High glass is cleaned from inside.

Ways to keep the bill smaller

• Photograph every opening before a film roll, a mesh panel or a grille is cut. A wrong reflectance or a wrong grille design is a wasted visit.
• Put the windows in one room on the same visit. A second trip is a second booking.
• If the track is only dirty, the published clean is S$60 to S$100. That is not a new roller.
• If the stay is rusty, stop. Film and a child lock on a failing sash do not make it safe. The approved contractor comes first.
• If you need privacy at night as well as in the day, ask for frosted film instead of buying a mirror roll.

No film, sticker or frosted-vinyl price is published on HomeySG. The rows below are neighbouring window jobs, so a heat film is not quietly billed as a reseal.

Anything not in that table is quote on inspection.
