🏫 Large school windows bring in plenty of daylight—but can also bring unwanted heat and glare.

Here’s one of our completed school window film projects, showing the finish outside and the view from inside.

Every building is different, so we assess the glass and recommend a suitable film for the school’s needs.

📩 School business managers, site teams and academy trusts: message Sentinel Window Films to discuss your building.

A perfect finish starts before the film even touches the glass. 👌

Correct handling and installation technique are hugely important with architectural window film.

Creases and handling marks aren’t always obvious while the film is wet — but as it dries and cures, they can become permanent and may eventually lead to premature failure.

That’s why we take care at every stage, from handling and preparation through to the final squeegee.

Quality film + correct installation = a finish that’s built to last.

🌤️❄️ UPGRADE YOUR EXISTING WINDOWS WITH CLIMATE GUARD

Better performance from the glazing you already have — all year round.

Climate Guard All-Season Window Film is a high-performance Low-E window film designed to upgrade existing glazing without the disruption and expense of replacing your windows.

❄️ WINTER — KEEP MORE HEAT IN
Climate Guard™ helps reduce heat loss through the glass, improving the insulating performance of your existing windows and helping rooms feel warmer and more comfortable.

☀️ SUMMER — KEEP EXCESS HEAT OUT
When temperatures rise, Climate Guard™ also helps reject solar energy before it builds up inside your home — helping rooms stay cooler and reducing uncomfortable hot spots.

🛋️ YEAR-ROUND COMFORT
As well as improving thermal performance, Climate Guard™ can reduce glare and block harmful UV, helping protect furnishings, flooring and interiors from fading.

🏠 UPGRADE, DON’T REPLACE

If your existing windows are still in good condition, replacing the entire glazing system can be expensive and disruptive.

Climate Guard™ allows us to upgrade the performance of your existing glass by professionally applying a virtually maintenance-free performance layer to the glazing.

✔️ Helps retain heat in winter
✔️ Helps reject solar heat in summer
✔️ Improves the performance of existing glazing
✔️ Reduces cold-window discomfort
✔️ Reduces glare
✔️ Blocks harmful UV
✔️ No need to replace perfectly serviceable windows
✔️ Professionally installed with minimal disruption

One glazing upgrade. Benefits in every season.

Already have double glazing but want to get more from it?

🏢 Commercial Window Film – It Starts With The Correct Specification

Commercial window film isn't simply about choosing a tint and fitting it to the glass.

Before installation, we assess the existing glazing, understand what the client wants to achieve and specify a film that's suitable for both the glass and the building.

Depending on the project, we can provide solutions for:

• Heat and solar gain
• Glare reduction
• Privacy
• UV protection
• Safety & security

With 26 years' experience in architectural window film, Sentinel Window Films can survey, specify and install the right solution for your building.

TWO DIFFERENT FILMS. TWO DIFFERENT PURPOSES ☀️

For this beautiful kitchen extension, our customer wanted to tackle two different problems.

On the large doors we installed our dual-reflective privacy film, giving much greater daytime privacy while still allowing a clear view out.

For the rooflights, we used our Vista External solar-control film, where maximum protection from solar heat and glare was the priority.

Rather than using the same film everywhere, we select the right film for each area of glazing and what our customer actually wants to achieve.

The result? More privacy, less heat and glare, without spoiling this fantastic bright space.

A recent installation completed for a commercial client experiencing excessive heat and glare through their glazing.

The brief was straightforward: significantly improve solar control without giving the building a highly reflective silver appearance from outside.

Following a survey of the existing glazing to ensure film compatibility, we specified and installed a 25% dual-reflective solar control film.
The result is effective heat and glare reduction while maintaining a much more subtle, neutral external appearance.

Sentinel Window Films provides professional commercial window film solutions for businesses throughout the Midlands and across the UK.

It’s reviews like this that make all the hard work worthwhile. ❤️

The last few weeks have been incredibly busy with installs, and the heat has definitely taken its toll on the team. We’ve been doing our best to keep up, and we know we haven’t always been able to reply to everyone as quickly as we’d like.

Reading a 5-star review like this is a great reminder that all the long days are worth it. A huge thank you to everyone who continues to support us, be patient with us, and take the time to leave such lovely feedback. It really does mean a lot to the whole team. 🙏🏼
