Are there any other products that Spectral Windows manufactures?
Apart from a vast selection of windows, doors and conservatories, in uPVC, Aluminium and Timber Spectral Windows offer plenty of decorative and performance glass.
Triple glass for when homeowners need that additional insulation throughout the year. Defined as three distinct panes of glass in a single unit, triple glass panels can offer significantly lower U-values, compared to single or even double glazing and can drastically improve on preventing noise intrusion.
Solar control glass helps to prevent the build up of heat during the summer months and is more ideal for larger applications and conservatories. The coating on the glass reflects the heat back and keeps the room comfortably cool.
Patterned glass is perfect for homeowners and businesses who desire a little more privacy but in a stylish way. Available in a wide selection of designs, these can be incorporated into any window or door application, offering additional privacy whilst still looking visually pleasing.
Decorative glass is a timeless craft that has recently enjoyed a revival over the last 20 years, with homeowners adding both character and charm to their homes with a staple piece of decorative glass embedded to their uPVC windows and doors.
Self Cleaning glass is a revolutionary product using a transparent layer of photocatalytic and hydrophilic mineral material that uses both the rain and natural light from the sun to break down and wash away any debris. Perfect for conservatories and extensions where you want to keep cleaning to a minimum.
