Double Glazing

Some of these include Gas-Filled Cavities, latest frame materials and use of advanced glass. If you want to lower costs of heating in areas of extreme cold then you must opt for a triple glazed window to keep the rooms comfortable and warm. No one offers a bigger choice of original designs for patterned/textured glass, in fact, you can choose from a range of 21 designs from traditional to contemporary. You'll be able to complete your project with an industry-leading secondary glazing solution. Granada-approved installers are trained and accredited by us, or you can employ your own fitter. Our manufacturer warranty is standard on all products, in addition to the installer’s warranty.
While this is far from an exhaustive list, what we hope it highlights is that double glazing in and of itself isn’t an out-of-the-box product, it’s a technique, and the result of a specific manufacturing method. All three glass packages in the Planitherm range – Energy Standard, Comfort and Comfort Plus – can be used in either double or triple glazing applications. The section of the glazed units should be no greater than 12mm (two layers of glass + cavity). Slim profile double glazing will cost in the region of £600 to £800 to install in an average 6-over-6 sash window. Dependant on the cavity size, glass type and choice of gas fill typical thermal transmittance values between 2.0 and 1.6 W/ SqM/K can be achieved.
Although this was a popular product for the time, aluminium double glazing was the next big breakthrough in the late 70s.

We apply the sealant in a molten state so that it flexes if the unit does and keeps the unit airtight. Sunlight produces short wave infrared radiation – this is what warms objects in the sunshine. The short waves are absorbed by glass from the outside and the energy becomes re-radiated from the inside of the glass as long-wave infrared. Internal condensation happens when the seals on the sealed unit begin to fail and more moisture is drawn into the unit. The desiccant becomes saturated and can no longer hold moisture and as a result, condensation forms inside the unit. As the sound wave travels, dense objects absorb the energy which reduces the frequency of the waves as it passes through.

The pattern was designed as shown, with the largest ellipses pointing North West. If you need replacement glass to match an existing design, don't worry, we have a number of well-established designs that are still available. Finally, fire anything you think might run (and assume any untested glaze will run) on something that will protect your shelves. Even better, use something with a raised centre (like my wheel thrown drip catchers) which allows for a little more glaze movement without sticking. It allows you to take slightly more risks with your glazing without ruining pieces or shelves.
Our secondary glazing fits into traditional and contemporary décor and doesn’t affect the appearance of existing windows. Engineered to fit exactly on or within the original window with a choice of many styles and colours, our range is designed to blend in. Style, colour and shape can be tailored to your exact requirements and specifications. Unlike double glazing, there’s no reason to replace your existing windows when you choose secondary glazing, allowing you to receive all the benefits with none of the hassle. Finance makes it easy to upgrade to double glazed windows now and spread the cost.
An insulated glass unit (IGU) combines multiple glass panes into a single unit system, for example a window. Double glazed units are made of two sheets of glass with a cavity between them that is generally 4-20 mm which creates an insulating barrier. IGUs help combat heat loss, making a building warmer, quieter and cheaper to run.These are prefabricated panels fitted into a single planar system. Our uPVC and Wooden windows have all been independently tested by the British Fenestration Rating Council (BFCR). When choosing your new double glazed windows, it’s important to know your options for energy efficiency. Choose from uPVC, wooden, or aluminium double glazed windows, each offering excellent energy efficiency and durability.

Low-E glass has an invisible coating that dramatically reduces heat transfer and reflects interior heat into the room. Low-E glass can make a big difference to a window’s thermal performance, whether it’s double or triple glazed. All VELFAC windows and doors are double glazed as standard, and deliver impressive thermal and acoustic insulation, which can be further improved with triple glazing. This style of secondary glazing is arguably the best solution in many cases, and requires fitting an internal secondary window behind your existing single glazed window.
If measured and fitted correctly, failed seal repair it will essentially form a double glazed solution for your windows - that in turn helps with heat retention, condensation reduction and security. Secondary glazing should always be fitted on the interior side of your window. Triple glazing is generally more efficient at reducing heat loss than double glazing, but it may not always be necessary or cost-effective. In some cases, double glazing may be enough to meet energy efficiency standards, especially if you have other energy-saving measures such as wall insulation. If this applies to you, it’s also worth mentioning that double glazing isn’t where the buck stops when it comes to the best insulative glass options. Technology moves fast, and triple glazing is now a viable option on everything from small windows to large panels.
