Stansted Airport Sound Insulation Grant Scheme can help fund acoustic upgrades for your home with secondary glazing leading the charge. 

Why Secondary Glazing Beats Double Glazing for Jet Noise. 

Standard thermal double glazing uses a tiny 12mm–20mm gap between glass panes. While great for trapping heat, that narrow gap actually amplifies deep, low-frequency sound vibrations the exact sound profile made by heavy aircraft engines. 

Secondary glazing works differently. By fitting a discrete, fully sealed glass unit on the interior side of your existing window, it creates a massive 100mm to 200mm air cavity. 

• Up to 80% Noise Reduction: A 150mm–200mm air gap with acoustic laminated glass cuts interior aircraft noise by up to 45 decibels. 

• No Planning Headaches: Because secondary glazing sits indoors, it requires no external changes making it ideal for listed buildings and conservation areas across Essex and Hertfordshire. 

• Thermal Insulation Bonus: You get reduced draughts and lower heating bills alongside peace and quiet. 

 

 

 

Bringing Classic Charm to Life: Vertical Sliders in Chelmsford 

Chelmsford is a city where history meets modern convenience. From the stunning architecture near the Cathedral to the Victorian terraces lining the streets of Old Moulsham, many homeowners face a common dilemma: how do you keep your home warm and quiet without replacing those beautiful, original sash windows? 

We recently completed a project in a stunning period property right here in Chelmsford, Essex, where the solution was simple but effective: Vertical Sliding Secondary Glazing. 

The Challenge: Draughts and Noise 

The homeowners loved their original timber sash windows—and who wouldn’t? They are a defining feature of the property's character. However, like many single-glazed sash windows, they were letting in more than just natural light. The owners were struggling with: 

* Heat Loss: Chilly Essex winters were making the front lounge uncomfortable. 

* Traffic Noise: Being close to a busy route meant the hum of commuters was a constant guest. 

* Conservation Restrictions: As the home is in a sensitive area, full window replacement was either too costly or restricted by planning guidelines.
