FAQ
Frequently Asked Questions
Straight answers about window film, privacy, glass safety and approvals.
Is window film allowed in HDB flats and condos?
HDB does not allow reflective film with more than 20% daylight reflectance on window glass, and BCA sets the same 20% limit for exterior building materials. Condos are governed by each MCST’s by-laws, and most do not allow mirror-like or very dark films.
We recommend films within these limits and can prepare product data sheets and samples for your MCST application.
Will one-way film give me privacy at night?
No. One-way (mirror) films work only when the outside is brighter than the inside. At night, with lights on inside, people outside can see in. For 24-hour privacy, frosted or decorative films are the honest answer.
Can film crack my glass?
Some glass types — for example large tinted or certain double-glazed units — can be at risk of thermal stress if the wrong film is used. That is why we check your glass type and orientation during the free site survey before recommending a film.
How long does installation take?
A typical HDB flat or condo unit can usually be completed in a day. Larger homes and commercial projects are scheduled with you in advance.
Who provides the warranty?
TTT TECH issues the warranty for your installation. The warranty period depends on the film you choose and is stated on your warranty certificate.
How should I clean the glass after installation?
Wait about a week before cleaning to let the film cure. Then use a soft cloth and non-abrasive, ammonia-free cleaner.
