Why choose Secondary Glazing in Wales?

Reduce heat loss

Are you losing heat? Reports show that up to 18% of heat is lost through your windows. Installing secondary glazing adds an extra barrier to prevent heat loss.

As secondary glazing is often fitted with a 150mm – 200mm cavity from the primary window, the air filled cavity acts as an insulator. The creation of an insulating layer of air is as important to the retention of energy as the fitment and seals. With the right glass, the result can be a reduction in heat loss by as much as 65 percent.

For thermal insulation, low-E glass is often the best choice because the glazing has been designed and engineered to provide:

  • the very best single glazing insulation
  • maximum energy conservation
  • an extremely discreet installation
  • an environmentally friendly solution
  • an affordable investment with quick returns

Astonishing sound performance

Are you losing sleep? Secondary glazing makes a home a whole lot quieter. Customers are amazed at the reduction in noise – many are able to sleep properly for the first time in years. Even if you live on a main road, next to a railway line or under a flightpath, Granada will change your life by drastically reducing external noise.

Increased energy efficiency

Heat-efficient secondary glazing reduces your utility bills, makes your home more comfortable, and minimises your environmental impact. With Granada, you achieve long-term performance and energy cost savings, during both cold and warm months. You also benefit from a better Energy Performance Certificate (EPC) rating.

Better and discreet security

Make your home unobtrusively safer and less vulnerable especially if you live in an older or listed building. No one wishes to sacrifice their property’s period or historic features in order to feel more secure – secondary glazing is the answer.

It reduces the need for unsightly grilles and other preventive methods. We have several options that will help you feel more protected whether you’re at home or away

Huge choice of products

Our entire suite of bespoke secondary glazing products are made to measure and feature a sleek, unobtrusive aluminium profile. Whether it’s for a modern townhouse or quaint period cottage, our product range is manufactured to the highest quality can be made to suit any existing décor

Horizontal Sliding Secondary Glazing

Suitable for a range of windows such as casement, hinged or any window with vertical bars. Available in two, three, four or five panels, the sashes can be completely removed when you need to clean the existing window.

Vertical Sliding Secondary Glazing

Vertical sliders are used in conjunction with traditional box-sash windows. A tilt-in option is available, enabling both panels to individually tilt into the room for easy cleaning.

Hinged Unit Secondary Glazing

Hinged casements are normally used in conjunction with casement windows or traditional box-sash windows. The glazed panes operate on hinges and open into the room.

Fixed Secondary Glazing

Our most simple secondary double-glazing product is typically used when the area for fixing into, is minimal. Once installed, the glazed panel cannot be removed.

Lift Out Secondary Glazing

Glazed panels are held in place with a slimline, robust aluminium outer frame. Panels are simply lifted out of the outer frame to give access to the existing window.
