Conservatory glass for year-round comfort
Getting the most out of your conservatory, orangery, garden room or sunroom is a crucial consideration when deciding on the specification.
Your choice of glass product is the single most important factor in cost-effectively controlling the climate inside your conservatory, along with other essential factors such as aesthetics, maintenance and longevity.

Heat reflection: measured by taking the opposite or inverse of the glazing solar factor. Solar factor is the percentage of the total solar radiant heat energy entering the room through the glass.
Thermal Insulation: a measure of the rate of heat loss through the glazing. A principal reason for installing energy-efficient glass, the lower the u-value, the better the glass is at retaining heat.
Glare reduction: measured by the inverse of 'light transmission', the proportion of the visible light spectrum that is transmitted through the glass. It is important to reduce the transmission of concentrated light, especially in the roof, to maximise visual comfort.
Self-cleaning glass: the self-cleaning coating is fully integrated into the surface of the glass ensuring its permanency. In a process called 'catalysis' the coating uses UV rays from the sun to break down organic dirt and turns the surface hydrophillic. Rain or hosepipe water then forms a sheet of water and rinses the dirt away.
Optimum Green
The flagship roof product due to its outstanding ability to reflect the majority (78%) of the sun's heat away from the conservatory, also offers enhanced glare reduction as well as all of the additional high performance functions as standard, together with an attractive aqua-green tint.
Optimum green leads the field in terms of product design and innovation, and helps create a truly flexible environment for year-round living.
Optimum Neutral
Optimum Neutral offers minimum tint and a neutral appearance, coupled with the technology to reflect 71% of the sun's heat away from the conservatory.
As with Optimum Green, Optimum Neutral maximises thermal insulation in the winter, eliminates glare from the sun, offers permanent self-cleaning capability and virtually eliminates condensation.
Optimum Blue
Optimum Blue has a subtle blue tint and the capability to reflect 68% of the sun's heat away from the conservatory.
Optimum Blue completes the roof options in the Optimum range. One that offers the highest available performance in roof glasses and flexibility in both aesthetics and performance.


Conservaglass represents a new generation of glazing options. In addition to keeping the sun's energy out in Summer and keeping the interior warm in winter, it stays cleaner for longer than conventional glass. Not only does it stay cleaner for longer but a transparent coating bonded into the external surface of the glass (not sprayed on to the sealed unit after production like some competitor products) uses the power of ultra-violet rays and the rain to break down dirt and grime and wash it clean away.
So whether it's for your roof only or includes the side frames too, specify Conservaglass and enjoy the comfort of your conservatory all year round.

• Blocks around 60% of the heat from the sun with excellent light transmission.
• True self cleaning glass- Infrequent cleaning required and easier to clean than standard glass.
• Excellent thermal performance in winter – very low 'U' value.
