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.

Enhancing Spaces with Exterior Glass Walls

 

A structural glass wall is a minimal and modern alternative to framed curtain walling, used to create large or long elevations of glazing where glass is the primary design feature. 

The continuous elevation of frameless structural glass units is seamlessly connected and joined together using specialist silicone joints. The result is a large glass elevation with no visible framing or fixings. The only visible sightlines are the neat silicone joints between each insulated glass unit. 

By using our thermally broken Invisio structural glazing system we can create exterior glass walls with high levels of thermal insulation with head and base fixings completely hidden by building finishes, meaning you can achieve a full floor to ceiling elevation of glass. 

 

Exterior Glass Walls in Contemporary Builds

Perfectly in line with minimalist aesthetics and design principles, the seamless, sleek nature of structural glass is ideal for contemporary projects.  

Both on horizontal and vertical faces of a build, large exterior glass walls provide a dramatic statement element to facades as well as rear elevations, as they can span across multiple floors for a striking contemporary finish.

 

Exterior Glass Walls in Traditional Builds

Glass walls offer additional aesthetic interest to traditional homes as well, as glazing structures create striking architectural contrasts between old and new design elements.  

Renovations, extensions and conversions often feature large elevations of glass to provide alternative natural light sources as well as adding a modern touch to the build without overshadowing its traditional character. 

 

 

Bespoke Exterior Glass Wall Shapes and Sizes

The size and shape of glass wall sections are manufactured bespoke to suit the specific design requirements of a given project. 

Through a modular configuration of both structural glass walls and ultra slim sliding glass doors, there is virtually no limit to the achievable sizes and elevations of exterior glass walls. 

 

Performance Enhancing Exterior Glass Walls

With the latest advances in architectural glazing, glass elements have become highly energy efficient, be if fixed or moving. Following the latest building regulations and wind load requirements based on the project’s location, exterior glass walls can greatly improve the overall thermal performance of the build.
