Our Editorial Process - How We Write Our Technical Advice Articles
01
We pick topics from real questions we hear or see being asked
We do not make up topics just to get clicks. Our topics come from the questions people really ask us. Architects ask us when they plan a building. Builders ask us on-site. Homeowners ask us when they plan their project. If the same question keeps coming up, we write about it.
02
One of our internal experts writes the first draft
The first draft is written by someone who works with that glazing system. This might be a technical advisor, a designer, or a product expert.
They write using three things, in this order. First, our own finished projects and what we learned from them. Second, the building rules and the glass standards that apply. Third, the maker's technical data for the system we supply. When we give a number or a limit, we say where it comes from. We name the rule or standard and link to the official source so you can check it yourself.
03
A second expert checks it
Before any article goes live, a second qualified person reads it. They check three things. That the facts are right and not made too simple. That any rule or standard we mention is current and stated correctly. That the advice matches how the work is really done on site.
This checker can send the article back, ask for proof, or stop it from going live. Two experts must agree. This is the most important safety step in how we work. The name of the person who checked each article is shown on the article itself.
04
We publish it, review it periodically and make fresh content updates to ensure ongoing accuracy
Each article shows who wrote it, who checked it, and the date it was last checked. Rules, standards, and products change over time. So we go back and review our advice on a regular basis. We update it when a rule changes, a standard is replaced, or a product changes. Being right matters more than leaving an old article alone.
How Does Heated Glass Work?
Heated glass is coated with a semi conductive, transparent metal oxide layer, which activates and radiates heat when electricity flows through it from concealed buzz bars at the head and base of the glass unit.
The transparent metal oxide coating is positioned within the inner surface of the outer glass pane to provide the utmost comfort, and the buzz bars are strategically concealed within the unit to ensure views remain unobstructed.
How is Heated Glass Controlled?
Heated glass can achieve temperatures ranging from 20° to 60°C, reaching the latter in as little as 20 minutes thanks to its low thermal mass.
When the wattage output of the glazing exceeds 100 W/m2, it is necessary to regulate the glass temperature using a room thermostat in combination with a temperature sensor positioned within the glass unit.
Additionally, heated glass can be integrated into building and home automation systems like any other electrical heating solution, as the system’s control panel can be placed as far as 50m away from the heated glass units.
Heated Glass Applications
Depending on the desired function, heated glass can be used as an alternative heat source or simply to stop condensation from forming on glazing systems. In areas where snow or ice build-up are a concern, the heated surface can be placed on the outside of the glass panes to avoid any cold-related sediments.
Cornwall Terrace
Frameless heated interior windows were incorporated into this spa renovation to create an open, broken plan design. This effectively divided the expansive interiors while preserving visibility across the entire floorplan. With such a highly glazed design, IQ’s Heated Glass plays a crucial role in ensuring the internal glazing remains completely free of moisture.
Claywood House
This low-carbon build combines unique materials and high-performance glazing to create a sustainable home. To achieve this, the design incorporated slim triple glazed sliding doors equipped with IQ’s heated glass in and around the indoor swimming pool, guaranteeing complete relief from condensation regardless of fluctuations in temperature.
Britten Street
In lieu of traditional underfloor heating, IQ implemented a specialized heated glass floorlight in a modern two-story rear extension in Chelsea, providing a much needed additional light source to the whole build.
By installing the heated floorlight directly below the rooflight, the resulting design allows light to permeate into the otherwise obscured basement rooms.
Controlled via thermostat, dwellers are enabled to enjoy sky views and natural daylight while radiating as much or as little heat as they desire.
Cheshire Pool House
Embracing a Miesian design approach, this pool house design incorporates two entire walls of heated glass, seamlessly blending structural glass walls with slim framed sliding glass doors. As the upper and lower glass panes are heated to prevent condensation accumulation on both floors, the glass remains consistently clear.
