Get Tranquil, Warm, and Secure Classrooms for Better Learning


Speak with Granada

Are your classrooms disturbed by noise outside? Are they not well-ventilated? Check out how Granada’s secondary glazing can help you.

Granada’s secondary glazing is a quick and affordable way to make any place of education tranquil and comfortable. This is a discreet, non-disruptive way to ensure that your educational institution is compliant with School Regulations.

The Education (School Premises) Regulations of 2012 have recommended that schools and centres of learning should have rooms that can block out sound.

It’s only logical that the best way for students to concentrate is by eliminating distractions.

The best way to do it is with our high-performance secondary glazing, which can reduce outside noise by up to 80%.

We have an immensely durable product that we manufacture and install ourselves.

As a result, we have full control on the quality and can ensure quick lead times and installation.

Our secondary glazing can be installed together with your regular windows, thereby enhancing their performance. It can be installed even your building is listed Grade I or II, or is in a conservation area.

In fact, such buildings benefit the most from our installations as they help improve the thermal efficiency without affecting the outward appearance of the building.

Frequently Asked Questions

To what extent will secondary glazing reduce the sound pollution in my home?

Correctly specified and installed, secondary glazing will acoustically outperform all other types of glazing. It is not uncommon to see secondary glazing where double or triple glazing is installed. To achieve up to an 80% acoustic performance Granada advise the specification of acoustic glass and an air cavity no less than 150mm – 200mm glass to glass.

Reports indicate that a passing diesel bus often creates 85dB of noise. Correctly installed, Granada’s secondary glazing can reduce noise levels by 54dB, a reduction of 54dB will reduce the noise level to 31dB which is the equivalent to a whisper.

What does the installation process consist of for secondary glazing?

Secondary glazing is installed to the interior side of the room creating little to no mess. Often installations can be completed within 30 minutes to 1 hour. To view the installation of secondary glazing please visit our video library web page: VIDEO LIBRARY

We work closely with over 500 national homeowner/trade customers who will make an appointment to measure and install at your convenience. For the DIY market, Granada can supply secondary glazing as supply only where installations videos and what measurements you need to take can be viewed here.

Will I lose the functionality of my windows?

Granada’s secondary glazing is available in many styles complimenting all window types. We have a range of windows that slide horizontally and vertically for easy access and cleaning.

Our hinged unit operates on a hinge mechanism that can be placed on the side of the window for conventional opening or on the top or bottom dependent upon your requirements. Other window styles include fixed windows or lift outs which can easily be lifted out of the frame.

Our Products for Schools and Education

We offer a complete range of window styles, including vertical and horizontal sliders, and other custom-built secondary glazing windows in more than 200 RAL colours. Granada’s products help improve the thermal performance, noise, and security issues for schools and education centres.

The benefits

Acoustic Dampening

Schools and education centres are required to provide a noise-free environment for students. This is easily accomplished with our secondary glazing which can reduce noise by up to 80% easily.

Thermal Performance

A comfortable temperature is essential for students in a crowded classroom. With our secondary glazing, you can ensure thermal performance where a room remains warm or cool for longer, with no additional energy consumption.

Extra Secure

Our secondary glazing adds to the security of the windows because of their strong frames, and the fact that they don’t require access from outside. This allows the classrooms to create a safe haven for students.


Education Regulations stipulate the amount of ventilation a classroom needs, which is not possible if you seal windows for insulation. With Granada’s secondary glazing, you can solve that issue easily.


The sturdy aluminium frames of our secondary glazing ensures that your installations last for years. In fact, we offer a 5 year warranty on all our frames and glass, and a 2 year warranty on all moving parts.

Outer Appearance

Since our secondary glazing fits discreetly on the inside of the windows, they help improve a building’s performance unobtrusively. As a result, they are a great choice for listed and heritage buildings.

Windows are an important and functioning part of any room, especially a school room. They allow light and ventilation, but unfortunately, they can also let in unwanted sounds and intruders.

Granada Glazing, as the largest manufacturer and supplier of aluminium secondary glazing, understands the importance of window performance.

We have built up years of experience with our extensive secondary glazing network across the country.

We bring to you aluminium secondary glazing products in a spectrum of more than 200 RAL colours. We can tailor the style and size of our aluminium products to whatever specifications you desire.

In fact, we are so confident about this that we give you a 2 year warranty on all its moving parts along with a 5 year warranty on the frames and glazing.

Our inconspicuous installations will continue to make your rooms better at thermal retention by up to 65%. Whether it is warm air in winter or cold air from air conditioning in summer, these fittings will keep your rooms at the temperature you want them.
