If you live in a period property or a listed building, you’re likely familiar with the "winter chill" that stubborn draft that seems to cut right through your beautiful original windows. While replacing those windows often isn't an option due to planning restrictions or cost, secondary glazing offers a brilliant workaround. 

But not all glass is created equal. If you want to maximize your thermal performance, there is one name that stands above the rest: Pilkington K Glass™. What is Pilkington K Glass™? 

Pilkington K Glass™ is a "low-emissivity" (low-e) coated glass. Unlike standard float glass, it features a microscopically thin, transparent coating on one surface. This coating is designed to reflect heat back into the room, making it an incredibly powerful tool for home insulation. 

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. 

If you pay your own energy bills, or contribute to them, you know the struggle of winter inflation. While you can wrap up under the covers with a hot beverage and comfort food, it doesn’t provide the same warmth your heater does. But the cost of constant heating amounts, so what can you do to prevent this?
