Value for Money
Fraction of the cost of replacement, comparable or better performance, and no disruption to the property.
The real numbers
Secondary glazing typically starts from around £163.66 per window, fully installed, depending on size, glass and system. A like-for-like replacement double-glazed timber sash costs several times more per opening — before scaffolding, redecoration and any planning fees.
- From ~£163.66 per window fitted
- No scaffolding required
- No internal or external redecoration
- One-day install per property
Performance per pound
Because the air-gap between the two panes is so much wider than a sealed DGU, you get better acoustic performance than replacement double glazing for a fraction of the outlay. Thermal performance is comparable or better with Low-E glass.
Long-term value
Powder-coated aluminium frames don't rot, don't need repainting and typically outlast the building's next redecoration cycle. Serviceable, sealed, and guaranteed for 10 years.
