Your double glazing options

Choosing new double glazing is really a series of small, satisfying decisions — the frame material, the window style, the glass and the little finishing details. This is your plain-English tour of the options, so you can arrive at your quote knowing roughly what you want.

There is no single “best” window. The right double glazing depends on your property, your budget, how long you plan to stay and simply what you find good-looking. The pages linked below break each choice down without the jargon, and every decision you make feeds into a quote we build around your home rather than a fixed package. If you want the quick version, you can also compare glazing types and quotes to get a feel for what suits you before you read on.

Start with the frame material

Most people begin here, and it is the choice that shapes everything else. uPVC, aluminium and timber each look and behave differently, and each sits at a different price point. Our uPVC vs aluminium vs timber comparison sets them side by side on cost, upkeep, thermal performance and looks. If you already have a leaning, jump straight into uPVC double glazing, aluminium double glazing or timber double glazing for the detail.

Pick a window style

Once the material is settled, the style sets the character. A flush casement sits neatly level with the frame for a crisp, understated look, while a standard casement has a subtle stepped profile that many homeowners prefer on traditional houses. Our guide to flush versus standard casement double glazing shows the difference clearly. Sliding sash windows, bays and French doors are all part of the same conversation.

Choose your glass

The glass inside the frame does a lot of quiet work. Toughened glass adds safety near doors and low windows, obscure glass gives privacy to bathrooms, and laminated glass improves security and sound reduction. Our glass options guide explains when each one is worth specifying. According to the Energy Saving Trust, replacing single glazing with modern sealed units can meaningfully cut heat loss, though the exact figure depends on your home.

Finish with hardware and handles

Handles, hinges, locks and colour finishes are the details you touch every day, so they are worth getting right. Chrome, brushed steel, black and gold-effect handles all change the feel of a window. Browse the hardware and handle choices to see how the finishing touches come together.

Match it all to your home

Finally, it helps to stand back and think about the house as a whole. A Victorian terrace, a 1930s semi and a new-build all suit slightly different combinations. Our guide to matching double glazing to your home pulls the choices together for period and modern properties alike. If you would rather compare suppliers than styles, you can compare double glazing companies side by side too.

For a wider view before you commit, it is worth reading our verdict on the best window materials and getting a sense of how long new windows last — both help set realistic expectations. When you are ready, we will turn all of it into a personalised quote.
