Switch glass

Rather than opening and closing your blinds as the sun dips in and out of clouds, switch glass allows you to change the transparency of your glass, at the push of a button! Switch glass is a ready-to-glaze type of glass, using a switchable polymer, allowing it to switch from being a transparent panel to an opaque one.

With the options of having your glass clear or darkened, this is an excellent choice, as it is environmentally-friendly, convenient, and very sleek looking.

Made out of a dispersed liquid crystal (PDLC) film that is sandwiched between 2 pieces of annealed glass, this luxury product is the perfect alternative to blinds and curtains. Additionally, the switch glass’ light transmission properties can be altered when light, heat or voltage is applied to the product.

Switch glass can help save you money; blocking out the sun on bright days, meaning you can turn down your air-conditioning.

Rooflight guarantees

  • 10 years guarantee for the window
  • 20 years guarantee for the glazing unit
  • Lifetime guarantee against hail damage

Ideal for brightening up new and existing flat roof extensions with natural daylight, the ECO+ switch glass flat glass roof window is engineered with energy efficiency and user convenience at the forefront of design.

Made out of a dispersed liquid crystal (PDLC) film sandwiched between two pieces of annealed glass, ECO+ switch glass windows negate the need for blinds by allowing users to change glass transparency from transparent to opaque in a matter of seconds with the press of a button.

Additionally, the switch glass’ light transmission properties can be altered when light, heat or voltage is applied to the product. ECO+ switch glass windows can be operated by either remote control or wall switch.

All units come with a exceptionally low U-value of 1.1 W/m²K, which indicates outstanding thermal performance, and a pre-fitted PVC upstand to save customers time and money on building and fitting their own.

ECO+ rooflights are manufactured with a low-E coated, double glazed window unit filled with argon gas and a warm spacer. This stops heat loss through the roof, creating a comfortable indoor climate that is not over-reliant on heating.

The ECO+ glass specification is as follows: 6mm Toughened Outer Pane / 16mm Argon Filled Cavity / 8mm Laminated Inner Pane.


The ECO+ maintenance free PVC frame is moisture resistant and therefore perfect for humid environments like kitchens and bathrooms, while the contemporary white internal finish fits all white-ceilinged rooms.

Keeping the exterior of the window clean is also easy thanks to the self-cleaning glass that comes as standard with every rooflight.


Safety is important factor of the ECO+ smart glass design. All units come with a toughened outer pane that will resist the impact of falling debris or any stray objects that might strike its surface.

Similarly, the inner pane has been laminated to keep it in place should it shatter, allowing you adequate time to find a replacement.


  • 10 years guarantee for the window
  • 20 years guarantee for the glazing unit
  • Lifetime guarantee against hail damage


For warm room installations, consider the ECO+ 150mm extension kerb to achieve 300mm upstand height.
