Where style meets sustainability

Spartan Modern windows are one of the most technically advanced windows on the market. This combined with an elegant angular frame, energy efficient glazing and high-quality handle and hinge fittings, makes for a window that has everything you’ll be looking for. Each frame sits fully flush on the interior for clean sharp lines and a subtle raise profiled on the exterior gives a modern textured look.

If you’re looking for a fully flush look, inside and out, check out our Spartan Heritage range. Perfect for replacing wooden frames for a highly realistic easy care alternative.

Our frames are strong and stylish. We take a core of recycled uPVC and wrap it in virgin uPVC to create a robust frame with a choice of beautiful finishes. Each frame contains 50% recycled material, so you’ll be doing your bit for the environment without compromising on the design

Replacement windows that are stylish yet strong

Modern Slim Rebate Windows - Spartan Range

Your windows don’t just need to look good, they need to protect you and your family against forced entry and they need to be built to last.

Our entire Modern range comes with extra secure multipoint key lock mechanisms with two steel shoot bolts that fix into the frame to provide added strength. The 6-chambered frame design provides an added element of strength, as well as energy saving benefits.

Our hinges come protected with a heavy-duty steel protectors as standard and we have a range of options to meet your needs:

  • Standard: smooth yet robust operating for top or side opening – tested to 30,000 cycles.
  • Fire egress: with full opening to 90 degrees, these windows provide full access and a means of escape in case of fire.
  • Childproof: allowing easy opening to only 10mm for ventilation and full opening by use of a discreet childproof button.

And good for the environment too…

One of the main reasons our customers look for replacement windows is to improve the energy efficiency of their home. There really is no better way to reduce heat loss through your windows than by installing modern double, or even triple, glazing.

Our Spartan Modern and Heritage ranges are the most energy efficient window systems available. An incredibly low U-value (a measure of the effectiveness of a heat insulator) is achieved with this frame – as low as 0.7 with triple glazing, which exceeds even the Passivhaus environmental standards.

Our panes are filled with a choice of dehydrated air or inert gas which prevents heat loss in the winter and helps to keep your home cool in the summer. Trickle vents are fitted as standard to ensure healthy levels of ventilation, especially in the winter months.
