Older single-pane or aged double-glazed windows often allow significant heat loss, so upgrading to modern, thermally efficient glazing and frames stops heat escaping during winter and keeps your home cooler in the summer. This directly helps in reducing your energy consumption and lowering monthly heating costs.
What’s more, windows that are sticking, warping, or have faulty locking mechanisms pose a real security risk. In older timber frames, wood rot or swelling can prevent the window from shutting properly (not to mention the dreaded regular painting required…). New, modern windows from KRB (in uPVC or aluminium) feature robust multi-point locks that make forced entry incredibly difficult and provide a reliable fire escape route in an emergency.
We are experts at window and door replacements, along with the complete build of garden rooms, extensions, verandas, sky rooms and conservatories.

Material choice comes down to budget, personal preference, existing style, type of property – in fact a whole multitude of factors.
uPVC Windows have improved vastly in recent years. They are thermally very efficient, much slimmer than they used to be, and available in a wide range of styles and colours.
Aluminium Windows generally have thinner frames, are mostly available in a greater range of colours and match well to other glazing options such as Roof Lanterns or Bi-Fold Doors.
Modern double-glazed sealed units are incredibly efficient at their ‘base’ level. But thermal efficiency can be improved through the use of Low-E or Solar Glass. These days, all frames are highly efficient through the use of multiple chambers or polyamide thermal breaks.
For the ultimate in efficiency, triple-glazed sealed units provide the very best (lowest) thermal loss, and are therefore the best choice, although not all frames are able to accommodate triple-glazed units.
When looking for the best choice, thermal energy loss (for the entire structure – glass and frame) is measured in Watts per square metre Kelvin (W/m2K), known as the U-value. A lower value is better.
Yes, they will! We measure the aperture into which your new window(s) will fit. We do this in order to quote, and then we will do this a second time before manufacture (the old measure twice, cut once adage…). This second measurement process is carried out by our surveyor to ensure there are no mistakes.
Then your windows are manufactured to the exact measurements, and our fitters ensure they carry out a perfect installation, fully sealed to ensure they are weatherproof and draught-free.
