At RBD Glass Ltd, we supply quality made-to-measure double glazing units designed to improve insulation, reduce noise, and enhance the energy efficiency of your property. Whether you’re replacing failed units or working on a new installation, we make ordering simple and accessible to everyone.
What Are Double Glazed Units?
Two panes of glass separated by a spacer bar and sealed to create an insulating air or gas-filled cavity. This design helps to:
- Reduce heat loss
- Minimise external noise
- Improve security
- Lower energy bills
We can match units to your exact specification.

Made to Your Exact Requirements
We manufacture to your precise measurements. You can customize:
- Glass thickness (4mm, 6mm, 6.4mm lam, 6.8mm lam)
- Unit thickness size (e.g. 14mm, 24mm, 28mm)
- Glass types (clear, low-E, toughened, laminated, obscure)
- Spacer bar colours (silver, black, white, etc.)
- Gas filling options (argon-filled for improved efficiency)
- Triple glazing (made of 2 spacer bars and 3 glass)
If you’re unsure what you need, our team is happy to help guide you.
Replacement Double Glazing Units
If your existing windows are misted, foggy, or have condensation between the panes, you don’t always need to replace the entire frame. We can supply replacement sealed units that restore clarity and performance at a fraction of the cost.
