Too much heat in summer. No privacy in the bathroom. Office partitions everyone can see straight through. Window film solves all of it. Professionally installed across Cambridge and Cambridgeshire, same day in most cases, with a 10-year warranty.
New obscure glazing means replacing the glass. Solar control glass means replacing it again. Replacing a full office partition to get privacy means a shopfit. Window film does all of it, applied to the glass you already have, in a matter of hours.
Professional installation makes the difference between a result that lasts a decade and one that starts peeling and bubbling within a year. Velfi's installation experience runs across NHS clinical environments, University of Cambridge buildings and luxury hotels, where a poor edge seal simply isn't an option. The glass is cleaned with specialist solution, the film is applied with professional tools and every edge is sealed properly. The job leaves no mess, the room is back in use immediately, and every installation is backed by a 10-year warranty in writing. For a deeper look at film types and where each one fits, see the window film guide for commercial and domestic buildings.

The difference between a result that lasts and one that doesn't.
Proper glass preparation
The glass is cleaned with specialist solution that removes contamination invisible to the naked eye. Contamination left behind shows up as permanent bubbles. Most DIY attempts fail here before the film even goes on.
Professional application tools
Film is applied and worked with professional squeegees that distribute pressure evenly across the entire surface. Every air bubble is removed methodically. The result is completely flat on day one and stays that way.
Edge sealing as standard
Every edge is finished and sealed properly. This is what stops lifting at the corners over time. Trimming flush to the edge is faster, and it is why budget installs lift. It also means the film starts lifting within months. Edge sealing is never skipped.

Which window film do you need?
Most people arrive knowing the problem, not the product. Match yours below, then follow the link for the full detail.

Professional or DIY?
When to fit it yourself, and when not to.
DIY film from a hardware shop is fine for a small window if you are patient and accept the odd bubble. On big panes, door panels, bay windows and anything you want to look finished, it tends to go wrong. Edges lift, bubbles show, and the film marks when it is peeled off and redone.
Professional installation fixes that. The film is cut to fit, the glass is properly prepared, the edges are finished, and the result carries a 10-year written warranty. Many people who tried it themselves first call us afterwards. Calling first saves the wasted film.
