SlimLine 38 Light, Elegance and Comfort
The slimline profile of our aluminium frames offers increased light into your property thanks to larger panes of glazing. The slender sashes and minimal frame reduce obstruction of your view to the outside and increase the light into your home.
The SL 38 system is designed to offer class-leading insulation levels without compromising on the appearance of the window. The result is a window that will keep heat loss through the window to a minimum, withstand the worst that the British weather has to throw at it, and will help keep your energy bills down.
Reynaers SL 38 windows and doors are designed and tested to the most stringent security standards. Knowing that the window has been awarded the Secured by Design accreditation means you can rest assured that your home, your family and your prized possessions are as safe as can be from would-be intruders.
