Solar control window film helps reduce solar heat, glare and ultraviolet exposure through existing glass while preserving useful natural light. Solar Heroes supplies and installs architectural window films for homes, offices and commercial buildings across Singapore, with options selected according to glass type, sun exposure, desired brightness, privacy and budget.
Singapore properties often receive strong, sustained sunlight through large windows. The effect can be uneven room temperatures, uncomfortable hot spots, glare on screens and faster fading of furnishings. Professionally selected solar window film improves the performance of the glass without the disruption and cost of replacing the entire window system.

Solar radiation reaching a window contains visible light, ultraviolet radiation and infrared energy. A solar control film changes how much of that energy is transmitted, reflected or absorbed by the glazing. The correct film can reduce unwanted solar gain while retaining the level of daylight and exterior visibility that suits the space.
The most useful overall heat-performance measure is Total Solar Energy Rejected, commonly shown as TSER. Infrared rejection is also useful, but it may be measured over a particular wavelength or wavelength range. For a fair comparison, review TSER together with visible light transmission, reflectance, glass type and the conditions under which the figures were tested.

Benefits for Singapore homes and buildings
- Improved indoor comfort. Less solar energy enters through treated glass, helping reduce hot spots near windows and making rooms more comfortable during periods of direct sun.
- UV protection. Solar Heroes' published product specifications state ultraviolet rejection of up to 99.9 percent for selected films. This can help reduce one contributor to fading of flooring, furniture, merchandise and interior finishes.
- Glare control. A suitable visible light transmission level can reduce harsh brightness and reflections on televisions, monitors and presentation screens.
- Natural light and exterior views. Near-clear and low-reflectivity options allow property owners to improve solar performance without automatically choosing a dark or mirror-like appearance.
- Potential cooling-energy savings. By reducing solar heat gain, window film may reduce the cooling load on air-conditioning systems. Actual savings depend on the building, glazing, orientation, film, operating hours, thermostat settings and occupant behaviour.
- Additional daytime privacy. Tinted or reflective films can make it more difficult to see into a property when the exterior is brighter than the interior. Curtains or blinds may still be required after dark.
Solar Heroes window film options
Solar Heroes offers several architectural film constructions for different priorities. The figures below are drawn from the specifications currently published by Solar Heroes and should be checked against the latest manufacturer data sheet before publication or quotation.
| Film | Construction | VLT | VLR | TSER | Suitable priority |
|---|---|---|---|---|---|
| Black Pearl 30HB | Nano carbon hybrid | 29% | 8% | 59% | Low reflectivity with stronger solar control |
| Ornyx Steel 30 | Metallised | 33% | 23% | 57% | Reflective performance and glare reduction |
| Spectra 65 | Nano ceramic | 70% | 7% | 50% | High daylight and low reflectivity |
| Spectra 35 | Nano ceramic | 37% | 6% | 60% | Balanced heat rejection and subdued brightness |
| P9970 | Multilayer polyester | 69% | 8% | 55% | Clear, non-reflective architectural appearance |
| P9940 | Multilayer polyester | 41% | 8% | 62% | Highest published TSER in the current range |
VLT means Visible Light Transmittance, VLR means Visible Light Reflectance and TSER means Total Solar Energy Rejected. A higher TSER generally indicates greater overall solar-energy rejection, while a higher VLT allows more visible daylight through the glass.

Request a Product DemonstrationHow to choose the right film
The best film is not necessarily the darkest film or the product with the highest single laboratory figure. Selection should begin with the room, the glass and the result the occupants need.
- Assess the direction of the windows and the hours of direct sunlight.
- Identify the existing glass type, thickness, coating and whether the pane is single, laminated or insulated.
- Decide how much natural light and outward visibility should remain.
- Consider exterior reflectivity, especially for condominium facades and commercial buildings.
- Compare TSER, VLT and VLR across suitable films rather than relying only on an infrared claim.
- Review privacy needs separately for daytime and night-time conditions.
- Confirm installation method, warranty coverage and aftercare before work begins.
Solar film for homes
Residential window film installation can be used in HDB flats, BTO homes, condominiums and landed properties. It is particularly useful for west-facing bedrooms, living rooms with full-height glazing, studies affected by screen glare and rooms where furnishings receive direct sunlight.
For homes, appearance and daylight are often as important as maximum heat rejection. Low-reflectivity ceramic, carbon hybrid or multilayer films may be suitable where residents want the glass to retain a natural look. Condominium owners should check applicable MCST renovation and facade requirements before selecting a visibly reflective film.
Solar film for offices and commercial buildings
Commercial window film installation can address glare at workstations, heat near perimeter glazing, uneven air-conditioning demand and UV exposure in reception, retail or display areas. A commercial recommendation should consider the glazing system, facade appearance, working hours, access, installation sequencing and the way the space is cooled.
For larger projects, Solar Heroes can survey the windows, document the proposed film and performance values, provide samples and plan installation to reduce disruption. Any energy-saving estimate should be based on site conditions rather than a generic percentage.
Professional installation process
- Initial consultation to understand heat, glare, UV, privacy and appearance priorities.
- On-site inspection and measurement of the windows.
- Product demonstration and comparison of suitable film samples on the actual glass.
- Written recommendation and quotation based on measured area and selected product.
- Protection of nearby floors, walls and furnishings before glass preparation.
- Application, trimming and edge finishing by the installation team.
- Final inspection followed by curing, cleaning and warranty guidance.
The film may initially show small moisture pockets or a slightly hazy appearance while the mounting solution dries. The expected curing period varies with the film, weather and window conditions. Customers should follow the aftercare instructions supplied for the installed product.

Frequently asked questions
Does solar control window film really reduce heat?
A suitable film reduces the amount of solar energy transmitted through the treated glass. The improvement depends on the film's TSER, the glass, window direction, area of glazing and intensity of direct sunlight. Film will not remove heat produced by roofs, walls, appliances or outdoor air entering the room.
Will solar window film make a room dark?
Not necessarily. Visible Light Transmittance indicates how much visible light passes through the film and glass. Solar Heroes publishes options ranging from lighter films with approximately 69 to 70 percent VLT to darker options intended for stronger brightness or glare control.
What is the difference between TSER and infrared rejection?
TSER measures the proportion of total solar energy rejected by the film and glass system. Infrared rejection describes performance against infrared radiation and may be reported at one wavelength or across a specified range. TSER is usually the more useful headline measure for comparing overall solar heat performance.
Can solar film block UV rays?
Selected Solar Heroes films are published with ultraviolet rejection of up to 99.9 percent. Window film can help reduce UV exposure through treated glass, but fading can also be influenced by visible light, heat, humidity, material quality and age.
Can window film provide privacy at night?
Tinted and reflective solar films mainly improve privacy when the outside is brighter than the inside. When lights are on after dark, people outside may be able to see in. Use curtains, blinds or a frosted film where stronger night-time privacy is required.
Is solar film suitable for every type of glass?
No film should be selected without considering the glass construction, pane size, condition and existing coatings. An installer should assess compatibility because an unsuitable film can increase thermal stress in some glazing systems.
How much does solar window film cost in Singapore?
Solar Heroes currently lists solar films from S$4.80 per square foot. The final cost depends on product, total area, access, pane layout, preparation and whether old film must be removed. An on-site measurement provides the most reliable quotation.
How long does solar window film last?
Service life depends on the film construction, exposure, glass, workmanship and maintenance. Solar Heroes currently states a minimum five-year on-site warranty for its solar films. The quotation should identify the warranty period and conditions for the selected product.
Can solar film reduce electricity bills?
Reducing solar heat gain may lower air-conditioning demand, but the actual bill reduction varies by building and usage. Window area, orientation, insulation, air-conditioning efficiency, thermostat settings, occupancy and operating hours all influence the result.
How do I choose between ceramic, carbon and metallised film?
Ceramic and multilayer films are often considered where low reflectivity, high daylight or signal-friendly performance matters. Metallised films can provide a more reflective appearance, while carbon hybrid products offer another balance of appearance and solar control. The choice should follow an on-glass comparison and review of the complete specification.
