What is Secondary Glazing?

It is not our intention to baffle anyone with science - Secondary Glazing is really not that complicated!

However, for those of a more technical nature or who would like more in depth details, information & specifications, please visit our Technical & Product pages and our Commercial, Specifiers & Architects pages.

Variously called Secondary Glazing, Secondary Double Glazing & Secondary Windows - they are all one & the same thing!

Most commonly referred to as Secondary Glazing.

Secondary Glazing can be fitted to most Windows & Doors.

It is usually a Single Glazed product (double glazed available for some specialist applications) with the glass panes secured by compression gaskets into extruded aluminium framing sections.

These in turn are usually mounted by way of rollers, glides, hinges or spiral balances into an extruded aluminium outer frame, allowing the individual panes or panels to hinge open or slide horizontally or vertically, thus allowing access to the existing primary window for ventilation.

The exceptions are Lift-Out Units & Fixed units, which as the names imply, are either Lifted In & Out or are Permanently Fixed!

The Secondary Glazing units are then fitted inside of the existing primary windows & doors.

Once fitted, Secondary Double Glazing has been created - it is a misconception that Secondary Glazing itself is Double Glazed.


How does it Look?

Because of the inherent strength of aluminium the panel & framing sections are considerably smaller than Timber or uPVC sections.

Our standard finish is White, we also stock a Brown & a Light Oak Wood-grain finish & can colour match to any RAL colour.

We have carefully designed our systems to be discreet & unobtrusive - in fact once installed in most instances they are virtually invisible - which can be a big problem for us in our promotional & advertising material!

All of the above windows have had our Secondary Glazing installed!

We carefully design each installation to use appropriate Secondary Windows that match the style & design of the primary window - making sure that the Secondary Panel & Frame Sections line up with primary window Mullions & Transoms.

Fixings are Hidden & Finishing Trims are scribed-in & fitted tight to the surrounds to ensure a perfect finish.

Once they are fitted you can forget about them & get on with your life, enjoying the same Uninterrupted Views from your Windows whilst enjoying the Benefits of a Warmer, More Comfortable, Securer, Less Noisy Home - with Reduced Heating Bills as the Finishing Touch!
