Window Film · Solar Control
Overheating rooms, blinding glare, fading furniture. Solar control film addresses all three without changing how your windows look from the outside. Applied directly to existing glass, it reduces solar heat gain by up to 79%, cuts glare significantly and blocks over 99% of UV radiation. No replacement glazing. No building work. One day installation in most cases.
What solar control film does
Solar control film works by selectively blocking the infrared and UV wavelengths that cause heat and fading, while letting visible light through. From the outside, the glass looks almost identical to untreated glass. From inside, the room stays brighter, cooler and more comfortable.
It works on existing glass — single, double and triple glazed — without any structural changes. The film is applied to the interior face of the glass and typically takes under a day to install.
Film options
Velfi installs a range of solar control films from 3M, covering neutral, reflective and low-reflectance options to suit different glass types and aesthetics. The right film depends on your glass specification, orientation and how much heat reduction is needed. Samples can be sent before anything is confirmed.
Reduce heat and UV with minimal change to the glass appearance. Ideal for residential and conservation areas where reflective coatings are not appropriate.
Maximum solar rejection. A mirror-like exterior appearance provides high performance in commercial buildings and south-facing glazed facades.
Good solar performance without the mirrored look. Popular for offices and domestic settings where clarity matters as much as heat control.
Typical installation times
No scaffolding. No structural work. The room is back in use the same day. Below are typical timeframes — exact times depend on the number of panes and access.
Half a day. The most common residential job — one or two south-facing windows in a bedroom or living room.
One day. Roof glass and side panels covered in a single visit. No disruption to the rest of the house.
One to two days. Can be scheduled out of hours or over a weekend to avoid any disruption to the working week.
