Solar Control Coatings

By using a Solar Control Coating on your architectural glazing design you can:

  • Reduce Solar Gain whilst maintaining light transmission and clarity
  • Reduce cooling costs in high glazed spaces
  • Create a comfortable internal environment with a minimal glass design
  • Suitable to be applied to almost any glass specification or product

With the rise in large glass elevations used in architectural design projects both residential and commercial. In addition, the technical advances in the thermal insulation of glass mean more and more architects include large glass elevations in their designs for a contemporary design aesthetic. As well as using a low e coating within the insulated glass, IQ Glass recommends that a solar control coating should be considered in design.

Solar Control Coatings

The solar control coating is applied to the internal face of the external glass panel of an insulated glass unit, also known as face two of the glass unit. The metal oxide coating reduces the amount of short wave radiation that travels through the glass unit thus reducing the increased heat levels inside.

There are a range of solar control coatings available, affording you different levels of light transmission, external tints and solar control. The most popular of these solar control coatings is a 70/35 solar control coating which maintains the unit’s light transmission at 70% for a natural appearance whilst reducing the G factor of the glass unit to 35%.

Solar Control coatings must always be used on an insulated glass unit, either double or triple glazed.

At the Showroom

Various levels of solar control glass can be seen around the newly renovated IQ Glass showroom, ranging from the standard 70/35 which is barely noticeable to the human eye, all the way up to a high-level solar control glass which acts as reflective glazing.

As with many technical glazing solutions, some clients worry that they will change the look of the glass. When visiting the IQ glass showroom, you will be able to see an example of 70/35 solar control glass incorporated into our double height, automated vertical sash window.

The vertical sash window sits next to a double height automated sliding pane without a solar control coating on the glass, as seen in the image to the left. This allows clients to see the difference on a large scale in person, side by side.

Tinted Solar Control

 

 

Light is beautiful. Excessive heat is not. IQ’s solar control coatings can be tinted to create striking statements using our advanced architectural glazing.

Tinted colours from warm grey, green, white and black complimenting the low-E and solar control coatings. Their neutral appearance is the most similar to clear uncoated glass.

Below are a few examples of tinted colours that can be applied to the solar control coating:

Solar Control Coatings for Commercial Projects

Architects and designers are challenging the use of glass in their designs and projects. The majority of architectural projects, especially commercial projects such as office and hotels use large glass facades, use solar control coatings to prevent hot, uncomfortable internal spaces that would be caused by Solar Gain through the glass elevations.

Controlling Solar Gain is a large element of modern building modelling and BREEAM calculations to ensure that large amounts of energy do not need to be expounded to cool down spaces that have not been properly designed.
