Roof Glazing Options

At KJM, we offer a wide range of choices for your conservatory roof glazing from polycarbonate to the very latest solar control, self-cleaning glass from Pilkington.

There are a number of options available to you:

Conservatory Roof Glass

  • Pilkington Cervoglass™ Therm
  • Pilkington Cervoglass™ Sun
  • Pilkington Activ™ including SunShade
  • Pilkington Standard Glass roof

Conservatory Roof Polycarbonate

  • Clear, Opal, Bronze, Bronze/Opal, Heatguard
  • 25mm or 35mm thickness options

Glass conservatory roofs need not cost the earth. As well as protecting you from the elements, they can now keep your conservatory warmer and more comfortable even in the cold winter months. Cervoglass Therm from Pilkington is an insulating glass unit for your conservatory providing both heat insulation and good light transmission. It is also available with the Cervoglass Sun option for south facing gardens (solar control glass). Cervoglass Activ provides self-cleaning, solar control, thermal insulation and optimal light transmission with a U-value of 1.1. Pilkington SunShade™ Blue can reduce the light transmittance to 0.27 and increase the Solar Heat rejection to 80%. This is ideal for a south-facing conservatory that requires total solar control. Further information can be found on the links below or on the Pilkington data sheet

Polycarbonate is a cheaper option for glazing your conservatory roof and is available in a variety of shades to suit each sunlight aspect. Available in both 25mm and 35mm, they have U-values of 1.7 and 1.3.
