Glass Specifications

Nova Neutral Plus high performance sealed units incorporate SGG Planitherm Total+. A new generation of energy saving window glass that uses advanced coatings to retain more internal warmth, whilst capturing free energy from natural daylight. This means your property should keep warmer without wasting any energy through your skylight.


Promotes Passive Solar Heat Gain

Free heat from the sun passes easily through the glass helping to warm the room with the fitted skylight. This free heat and light from the sun (known as passive solar heat gain) is passed through the glass, warming your home and further contributing to the energy efficiency of your windows.


Less Condensation

The inner surface of our skylight glass stays warmer which help keep condensation levels down as much as possible.


Neutral Appearance

There is no unsightly tint from our standard glass unlike traditional low-E coatings that suffer from an unsightly yellow tint, Neutral Plus windows look very clear.


More light

Less tint from the glass fitted in our skylights means more light can enter the room, this makes your room more comfortable and luminous.


No ‘Haze’ Effect

Neutral Plus does not suffer from the unsightly haze commonly associated with traditional low-E products.


Reflect the Heat Back into Your Room

Neutral+ Sealed Units incorporating Planitherm Total+ Technology have a transparent metallic coating that reflects heat from radiators or fires back into the room, rather than allowing it to escape through the windows.
