Glass and Glazing

Windows, Doors, and Conservatories

Secondary Glazing

Often the secondary glazing route is the only way you can achieve the benefits of double-glazed replacement windows. You may live in a conservation area, or maybe your property is a listed building. It could also be that you are in a long-term rental lease or a joint freehold arrangement and therefore limited as to how windows and doors can be renewed.


Naturally, installing secondary glazing has to meet the stringent standards set by the local council and agreed by your landlord. You also want your secondary glazing to flow with the rest of the building and the style of your rooms.

So, value-led complementary and unobtrusive design with concealed fixing, which causes a minimum of disturbance and leaves you with only minor redecoration, is the ideal solution that JP Glass provides. A no-frills approach to providing answers and estimates is how we can offer you a truly bespoke service.

Granada™, our preferred choice of supplier, provides outstanding noise reduction with their secondary glazing. Thanks to its unique soundproofing capabilities, secondary glazing can reduce noise pollution caused by various sources. For many homeowners, traffic noise is their biggest concern. In these instances, secondary glazing with thicker glass and fitted correctly, can make the world of difference.

Warmth is a valuable commodity and creating a second barrier to the elements is an ideal way to reduce wasteful thermal heat loss. 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 reduction in heat loss by as much as 65 percent.

For thermal insulation, low-e glass is often the best choice due to the glazing being 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

The resulting installations can exceed building regulations' requirements, offering significant cost savings in the process. It is also the product of choice for traditional buildings and properties, listed buildings, and conservation areas, maintaining their appearance, character, integrity, and value.
