We recently completed a successful installation of our secondary glazing in a quaint cottage in Ashbourne. Our client, Chris, was facing heat loss issues, particularly in this beautiful old building nestled in the Derbyshire countryside.
By installing our secondary glazing with a slight upgrade on glass thickness, we've effectively addressed Chris's concerns. Now, he'll save significantly on energy costs by eliminating drafts. Additionally, the installation adds an extra layer of security to the building, while also providing sound reduction benefits. We're delighted to have provided a solution that enhances comfort, energy efficiency, security, and tranquility for Chris in his charming cottage.

ASHBOURNE COTTAGE

WEST RIDING HOUSE

We recently undertook a fascinating project involving a school where our client's primary concern was enhancing security. In addition to addressing this need, our secondary glazing solution also provided added benefits of preventing heat loss and reducing noise levels. What made this project particularly interesting was our proposal to work during the night to avoid disruption to the classrooms. Our dedicated secondary installations team efficiently completed the project in just a few evening and night shifts, allowing them to rest during the day while ensuring minimal disturbance to the school's activities. This approach reflects our commitment to meeting client needs while considering the unique requirements of each project.

EAST WEST BUILDING

For this commercial project, we installed secondary glazing using Thermal 6.4 Low E glass, designed to minimise heating bills by improving energy efficiency. The installation was smooth and precise, with no mess or mistakes, ensuring a perfect fit. We carefully removed a subframe on one side to reduce the mullion width for enhanced sightlines. While measuring for this job involved a complex behind-the-scenes process, we enjoyed every challenge and are proud of the flawless result.

ASHBOURNE DRAYCOTT-IN-CLAY

Outside the property stood a charming hedge sculpted into the shape of a teapot—a delightful feature that reflected the unique character of this home. Our client sought secondary glazing to improve energy efficiency and retain warmth, particularly important given the property’s exceptionally high ceilings.
The project was efficiently completed over two visits: one day dedicated to the installation and another for trimming and sealing. By utilising a specialised fitting team and a dedicated trimming team, we ensured a seamless and precise process. This successful project in Ashbourne, Derbyshire, exemplifies our commitment to delivering efficient, high-quality solutions tailored to our clients' needs.
Thanks to their new secondary glazing, our client can now enjoy enhanced insulation and reduced energy costs. At Invision Glazing, we take pride in enhancing both comfort and efficiency in every project, providing exceptional service and results that speak for themselves.

Portfolio

Recently had Invision Secondary Glazing Ltd quote, supply and fit 2 secondary glazing windows and a new composite door to a grade 2 listed building. The service was excellent from start to finish, Lee fitted the windows and Aaron fitted the door. Both were very knowledgeable and professional. The secondary windows and the door have already proved they are worth the expense as the noise levels in the building have dropped considerably and our EPC rating has now improved. Would highly recommend!

Invision did exactly as promised. On budget. On schedule. And the glazing looks perfect. We are cosy and peaceful.
Aaron managed the project from quote, through survey to contract.
Steve and he managed the installation.
Lee and Glenn were thoroughly professional as the installers working with them. And Glenn even discovered that he enjoyed classical music!
Thank you all.

Such a fantastic service from start to finish. We had great advice whilst choosing our windows, they arrived when promised and the fitting team were wonderful. Can’t recommend the team and service highly enough, and what’s more we’ve now got beautiful secondary glazing which looks great and has made our house so much easier to heat. Have ordered more windows already!!

Installed secondary glazing in large sash Georgian windows and did a really good job. You can hardly tell they’re there and seem efficient with heat retention. Friendly, professional staff that sorted everything exactly as planned and slightly ahead of schedule. Highly recommended.

What Is Secondary?

Secondary glazing involves installing an additional pane of glass on the inside of an existing window, creating an extra layer of insulation and soundproofing. This system enhances energy efficiency by reducing heat loss and improving thermal insulation, helping to keep your space warmer in winter and cooler in summer. It also significantly reduces external noise, making it an ideal choice for homes in noisy areas or historic buildings where replacing original windows might not be possible. Secondary glazing is a cost-effective solution that complements your existing windows without the need for major alterations.

Heat Loss Prevention

Secondary glazing saves heat loss by adding an extra pane of glass inside your existing windows, creating an insulating air gap. This gap acts as a barrier to prevent heat from escaping and cold air from entering, effectively reducing heat transfer. The additional layer helps to keep your home warmer in winter by trapping heat inside, leading to lower energy bills and improved comfort.

Noise Reduction

Secondary glazing reduces noise by adding an extra layer of glass to your windows, creating a sound-absorbing air gap between the two panes. This gap acts as a buffer that helps to dampen and block sound waves, reducing the amount of noise that travels through the window. The added pane helps to minimize external noise, making your indoor environment quieter and more peaceful.

Extra Secure

Secondary glazing enhances security by adding an extra layer of glass to your existing windows. This additional pane makes it more difficult for potential intruders to break through, as they would have to penetrate both layers of glass. Additionally, the secondary glazing is often fitted with robust frames and seals that further reinforce the window's resistance to forced entry. The added layer also makes it harder for burglars to see inside, providing an extra level of privacy and deterrence.
