Clear, Solar or Privacy Glass: Which Rooflight Glass Is Right for You?
The right rooflight glass depends on what the room needs most. Clear Low E gives the most daylight, Solar Clear limits heat from strong sunshine, Solar Grey reduces glare and Satin Privacy blurs the view for bathrooms and overlooked rooms. Each finish is available with double or triple glazing.
What Low-E Glass Does in Every Rooflight
Every glass option includes a Low-E coating as standard. This invisible layer reflects heat back into the room in colder months and blocks a significant amount of ultraviolet light, which helps protect flooring and furniture from fading. All units also use toughened safety glass, which is far stronger than ordinary glass.
Clear Low E Glass for Maximum Daylight
Clear Low E is the most transparent choice and lets the greatest amount of daylight into the room. It works particularly well in north-facing spaces, hallways and rooms that receive little direct sun, as well as above a bed where the view of the sky is part of the appeal.
In a south-facing room, fully clear glass can feel very bright on summer afternoons. Understanding rooflight orientation before ordering helps you judge how much direct sun the glass will receive through the day.

Solar Clear looks almost the same as clear glass, giving full transparency and an uninterrupted view of the sky. The difference is that it reflects part of the sun's heat away before it enters the room. This makes it a sensible choice for kitchens and extensions that face the sun for much of the day, where bright light is wanted without the room warming up too quickly.
Solar Grey Glass for Reducing Glare
Solar Grey has a subtle grey tint that tones down direct sunlight. The room still receives plenty of daylight, but the light feels softer and more even. Home offices, living rooms and dining areas benefit most. Reducing glare at the dining table is a common reason homeowners choose it.
Satin Privacy Glass for Overlooked Rooms
Satin Privacy glass has a frosted finish that allows daylight to pass through while obscuring clear visibility. It is the natural choice for bathroom rooflights, en-suites and any room overlooked by a neighbouring window. The light it creates is soft and evenly spread across the room.
Double or Triple Glazing With Your Chosen Glass
Double glazed units have two panes of glass and achieve a U-value of up to 1.0 W/m²K. A U-value measures how much heat passes through, so a lower figure means better insulation. Triple glazed skylights add a third pane and reach a U-value of up to 0.5 W/m²K, which suits bedrooms and homes where lower heating costs are a priority. Both options meet Building Regulations Part L, which sets energy efficiency standards.
Choosing the Right Glass for Your Rooflight
A simple way to decide is to start with the room's main problem. If it is dark, choose Clear Low E. If it gets too warm, choose Solar Clear. If bright light is uncomfortable, choose Solar Grey. If privacy matters, choose Satin Privacy. Room-by-room advice on choosing glazing for kitchens, bedrooms and living rooms can help where a space has more than one need.

Clear Low E glass lets in the most daylight because it has no tint or frosted finish. Solar Clear is very close in appearance, while Solar Grey and Satin Privacy soften the light slightly.
No. Solar Grey still brings in plenty of daylight. It simply reduces the intensity of direct sunlight, so the room feels bright but more comfortable.
No. Satin Privacy glass lets light through but blurs shapes and detail, so neither people inside nor anyone overlooking the roof can see clearly through it.
Every finish includes a Low-E coating as standard. The biggest difference to heat loss comes from choosing double or triple glazing rather than from the finish itself.
Yes. A larger room can combine finishes, such as Solar Grey above a seating area and Clear Low E above a kitchen worktop.
