Standard and bespoke shapes
From arched and bay windows to curved and circular glass, Granada has the facilities and expertise to produce complex angled bespoke windows. Even stained glass, leaded lights and historic glass can all be secondary glazed.
Many windows in older, more traditional properties are out of square. In most cases, standard secondary glazing can be installed by shaping of the timber sub-frame and using bespoke windows with matching finishing trims.
Through our previous renovations of churches and historic buildings, we have a wide range of existing styles and templates which we can also modify to minimise your costs.

Superior aluminium
We use industry-leading aluminium profile that is slim but incredibly strong and stylish. This means all Granada frames are able to hold a heavier weight without losing structural integrity, allowing us to cater for very large window applications.
Our bespoke secondary windows retain the original characteristics of existing windows, whilst taking advantage of design, material and production advances.

Bespoke Secondary Glazing FAQ's
What type of windows do you provide bespoke secondary glazing for?
Our secondary glazing can be manufactured to suit virtually all types of primary window, including arched, curved in plan and circular units. Though our online quotation and ordering system doesn’t currently accommodate for bespoke units, be sure to contact our team who’ll be happy to meet your requirements.
What window glass do you offer for bespoke secondary glazing?
All of our bespoke secondary glazing can be made to accommodate 4mm toughened to 10.8mm acoustic laminated glass. We offer the most extensive glass selection of any secondary glazing manufacturer to ensure homeowners enjoy the best possible thermal and acoustic performance.
Does your bespoke secondary glazing stop heat loss?
Bespoke secondary glazing, much like our entire suite of products, is incredibly effective at retaining a buildings heat. Our arched units in particular can be fixed either within the reveal or to the face of the primary window, providing an extra barrier against draughts and cold spots.
How much does bespoke secondary glazing cost?
The cost of bespoke secondary glazing will depend entirely on the type of primary window with which it’s being paired. Be sure to contact our office with your exact requirements for an accurate secondary glazing price.
What are the key differences between secondary glazing and double glazing?
Secondary glazing and double glazing are two completely different products. Secondary glazing features the installation of an independent window unit on the inside of the primary window. Double glazing is quite simply a glass spec within a primary window. A combination of double glazing and secondary glazing can be incredibly effective at improving both thermal and acoustic performance.
