Love your bi-fold doors, but not the heat that comes with them?
Bi-fold doors are brilliant for flooding a room with natural light and opening up the view to the garden.
But all that glass can have a downside.
When the sun hits a large area of glazing, rooms can quickly become uncomfortably warm — with increased heat, glare and UV exposure often leading to closed blinds or curtains just to keep the room comfortable.
For this recent Shades Window Films project, we installed Silver 20 internal solar control window film to the property's bi-fold doors.
The film helps to:
✅ Reduce unwanted solar heat
✅ Cut uncomfortable glare
✅ Reduce UV exposure that can contribute to fading
✅ Maintain natural daylight
✅ Make heavily glazed rooms more comfortable
And because it's applied to the existing glazing, there's no need to replace the doors.
We've taken a closer look at why rooms with bi-fold doors can overheat and how the right solar control window film can help in our latest guide.
