The challenge

Retaining Character While Improving Comfort

The goal was clear: upgrade to double glazing without losing the authentic look of traditional timber sash windows. Cost was also a factor for the single homeowner.

After getting some advice from her son, a glazier, the homeowner explored uPVC windows as an alternative to timber. The result was a solution that delivered both energy efficiency and heritage style — without the high cost of wood.

The solution

Style and Comfort with NK Windows uPVC Double Glazing

Installed in 2024 by NK Windows, the new uPVC double glazed windows were carefully selected to complement the villa’s original aesthetic.

Inside and out, the transformation is subtle but powerful:

  • uPVC windows are in keeping with the traditional timber look
  • Improved thermal insulation for year-round comfort
  • Reduced draughts and noise
  • Low-maintenance frames ideal for busy homeowners

Expert Guidance Makes the Difference

A key part of the journey was working with the NK Windows team, who helped guide design decisions — right down to the finishing details.

NK Windows also connected the homeowner with a builder experienced in villa renovations, ensuring the installation respected the structure of the home, particularly when it came to rebuilding a bay window in the living room, which had been badly affected by borer.

The result

A Warmer, More Liveable Villa

Alongside floor and roof insulation upgrades, the new windows have set the home up for much more comfortable winters, without compromising its heritage appeal.

And the street presence? Better than ever. The homeowner is clearly delighted to have one of the prettiest houses in the area.
