Modern Glass Technology by IQ Glass

Triple Glazed Sliding Doors

The minimal windows 4+ system, exclusive to IQ Glass within the UK, is the most technically advanced slim framed sliding glass door available in architectural glazing.

Using an engineered triple glazed unit, and maintaining a slim aluminium frame of only 26mm, you can create large sliding glass doors of up to 4.5m high and 12m2 for each sliding panel with exceptional levels of thermal performance and weather resistance.

There are no restrictions on the number of sliding tracks you can have. Keep in mind that each sliding track is approximately 88mm deep with a two track sliding door at 174mm deep and a triple track slider at 269mm deep. 

As well as increased levels of resistance to air permeability, water and wind loading these triple glazed sliding doors have also undergone specialist testing for resistance to hurricane levels of cyclic wind and driving rain. The hurricane tests also incorporated missile impact testing to recreate the experience of objects being thrown in a storm.

You can see from the impressive resume of the minimal windows 4+ that if you are looking for a high performance, minimal sliding glass door the minimal windows 4+ far outstrips the rest.

Oversized Glass Doors

With a maximum sliding glass door of up to 12m2 you can create extensive walls of sliding glass with a thin vertical frame of only 26mm keeping a frameless surrounding finish.

Using a triple glazed unit with a Ug value of 0.7 W/m2K it is very possible to achieve sliding glass walls with a Uw value of 0.9W/m2K depending on the configuration of the sliding doors 

The minimal windows 4+ has been fully detailed and designed to include a discrete locking device, high volume drainage and hidden automation as required whilst maintaining that minimal design finish that is created from the minimal windows system.

These triple glazed sliding doors are designed to be opened manually however if each sliding glass panel weights over 500kg then we may recommend including an automated drive to open the doors automatically. This motor can be hidden within the ceiling void internally for an invisible finish.

The number of sliding panels you can have is nearly endless with 2, 3, 4 or more tracked sliding doors possible. Pocket doors, opening corners and Juliet balconies are also possible adaptions that can be made to the triple glazed sliding glass doors enabling them to be adapted to almost any design project.
