Opening Elements

Glass links are an endlessly versatile structural glass installation that can connect the past and future aspects of a building. This architectural design is not only a practical solution to connecting various areas of a building but they are also visually stunning designs.

IQ Glass have designed and installed many bespoke glass links to a variety of buildings from luxury apartments to heritage manor houses and listed cottages. Frameless glass in a elegant design that is capable of creating a link between traditional and modern architecture without taking anything away from the beauty of these juxtaposing aesthetics.

These glass links can be constructed using single glazing or insulated glass units such as triple or double glazing for a thermally efficient installation. Opening elements, such as doors for glass links, can be integrated into the structural glass construction for freedom of movement between spaces. On a single glazed installation opening doors from IQ’s Frameless Interior System can be incorporated into the structural glass installation for a completely frameless finish.

IQ Glass will design and engineer the building connections, the glass to glass joints and all fixings for a sleek glass installation that will pass even the most stringent planning officer’s approval. IQ Glass are experts in structural glass design and work closely with architects to ensure the connections between the glass and existing building is minimalistic and seamless. Fixing methods can vary to suit each project need, with the option to chase all fixings into the stonework, if possible, for a completely frameless look.

Glazed links can either be designed with a highly frameless aesthetic or with built in elements that are designed to make an impact on the overall design such as framed doors, timber supports or a solid roof. For a frameless design, frameless structural glass beams and frameless glass roofs can utilise within the design for a frameless design.

Integrated Doors

It is possible to integrate any of our architectural glass doors into your glass link design. Which door system that is most suitable for your glass link structure will depend on design intent and budget.

In keeping with the minimal design of a structural glass link a slim framed system is often preferred such as a minimal window® or a Vitra Pivot. 

Wherever an opening is integrated into a structural glass installation additional steel support may be required to create the opening in which the door is going to be installed. These additional steel supports are designed to be as minimal as possible whilst ensuring the structural integrity of the glass link.

When a steel support has to be included as part of the design it can be finished in a number of ways to ensure a cohesive design. Back painted glass covering the steel will offer a sleek, all glass look. Alternatively an architectural metal or aluminium pressing can be used to match the door system.

Glass Specification

We will design a bespoke glass specification for your glass link, designed around the structure size and performance requirements. 

Glass links can be created using single glazing or insulated glass (double or triple glazing). If the glass link space needs insulating properties then we will need to use double glazing as a minimum. 

As a glass link is a structural glass design the inclusion of laminated glass panes is often used to increase the strength of the glass unit and create a safe structural glass design. 

Any glass to glass connection is designed by the team at IQ to be very minimal. We are able to employ our years of experience in structural glass design to create frameless glass links with no framework required.

Invisio Technical Details

We use our exclusive structural glass fixing system - Invisio - to connect the frameless glass panes of your glass link to the building structure. 

The Invisio system is fully thermally broken which ensures the glass link includes no thermal briding and can achiever high levels of thermal insulation. Uw values from 1.1 W/m2K are very possible which allow these glass connecting spaces to be open parts of a building.

All other glass connections within the glass link installation can be completely frameless, including glass to glass connections between vertical and roof glazing, and corner glazing.

You can download the typical Invisio CAD details via this link.

Once IQ are appointed to the project we will created detailed and bespoke details for your project.
