In-House Design and Contract Management

See our in-depth article here for how we manage an architectural glazing installation: Our Contracts Process

Once your quotation is approved and an order has been placed your project will progress to IQ's in-house design department. Here all the fixings, glass compositions and construction will be designed in detail by IQ's expert designers. If CAD blocks have been provided, IQ can supersede these glass designs onto the construction DWG files. A dedicated contract manager will be appointed and will be your one point of call throughout your project. Any questions or issues, your contracts manager will be available to assist.

When materials have been ordered installation dates can be agreed. IQ's in-house installation team will arrive on time and in full IQ uniform ready to install your architectural glazing. All installation teams have a clear hierarchy with a team leader in direct contact with your contract manager throughout the installation

Time, money and dedication has been invested in IQ's company infrastructure to ensure a smooth movement of goods, materials and systems to sites all over the UK.

Our commercial fleet includes over 60 liveried vans which deliver glazing systems and installation teams to building sites all over the UK. Each of our vehicles are custom fitted with all the equipment and accessories we need to conduct a successful architectural glazing installation.

With three factories and fabrication locations around the north and west sides of the M25 the IQ Glass Group is well placed to provide glazing nationwide. Our strategically placed manufacturing facilities serve IQ Glass with a steady supply of aluminium and steel systems which we install on our projects.

Post Installation Support

Once the installation has been completed your project will now be a proud home for a high specification top engineered architectural glass installation and is guaranteed to be a focal point of your design.

As public awareness of the IQ brand grows our completed glazing projects are continuously being featured in media publications such as Real Homes, Living Etc, Homebuild and Renovating as well as popular TV programs like George Clarkes Amazing Spaces, Sarah Beeny's Double Your House for Half the Money and of course Grand Designs.

IQ encourage architects and specifiers to share their architectural glazing images with us on any major social media channel which we can then share for further exposure.

Our reputation is important to us and we strive to solve any post-installation issues as swiftly as possible. There is a reason that architects specify us on their projects time and again, and our reactive response to any problems is just one of them.
