Here's why secondary double glazing is worth considering:

Enhanced Energy Efficiency or Thermal Efficiency
One of the primary advantages of secondary double glazing is improved energy efficiency. By creating an extra layer of insulation, it minimizes heat loss through your windows, keeping your home warmer during the winter and cooler in the summer. This can lead to noticeable savings on your energy bills, making secondary glazing a cost-effective alternative to replacing your windows entirely. Many homeowners opt for this solution to enjoy the perks of double glazing without the higher price tag.

Soundproofing or Noise Reduction
If you're living in a busy urban area or near a noisy road, sound proof windows are essential for maintaining peace and quiet in your home. Secondary double glazing provides an effective soundproofing solution, significantly reducing external noise. The additional glass layer and the air gap act as a buffer, absorbing and deflecting sound waves. This makes secondary glazing a popular choice for those seeking quieter living spaces.

Increased Security for your Home
Secondary double glazing enhances your home's security by adding an extra barrier to entry via your windows. The additional glass pane makes it more difficult for potential intruders to gain access, providing you with peace of mind. For added security, you can also add additional locks which we can supply.

Cost-Effective and Easy Installation
Compared to installing brand-new double glazed windows, secondary glazing is a far more affordable option. It doesn't require the removal of existing windows, which simplifies the installation process and reduces costs. It typically takes us LESS THAN 1 HOUR to install the new window or door.

Modern secondary glazing systems are discreet and can be customized to match your home's style, ensuring that you don't compromise on appearance.

By reducing heat loss and creating a more stable internal temperature, secondary double glazing helps prevent condensation from forming on your windows. This is vital for protecting your home from mold and damp issues, which can cause long-term damage and health concerns.
