Best paired with sash windows, and opening from top to bottom, our vertical slider units are also available with a special slide-pass or tilt-in function, which means both panels can individually pivot inwards for easier access and cleaning.
As you'd expect from secondary glazing, choosing one of our vertical slider units offers you numerous advantages, including improved sound insulation, enhanced thermal efficiency, increased security, and reduced condensation.
“Vertical sliders are ideal for those who want the look and feel of classic sash windows but with added comfort. The panels move smoothly and independently, and our tilt-in version makes regular cleaning much easier. They’re discreet in appearance but offer real improvements in energy use, security and sound insulation. It’s a thoughtful solution that works well in both homes and heritage buildings. With features like integrated locks and restrictor arms, they balance style with safety.”
Due to their durable design and exceptional construction, vertical sliders require minimal upkeep. Once they have been installed, they are easy to clean and maintain, making them a versatile, long-lasting addition to your home.
Vertical sliders create an extra layer of insulation, helping to reduce heat loss and improve your home's energy efficiency. This added barrier has the additional benefit of keeping your home warmer in winter and cooler in summer.
With vertical sliders, you gain an extra layer of protection. The secondary glazing enhances your home’s security by adding another barrier against forced entry, giving you greater peace of mind.
By adding vertical sliders, you can help prevent condensation build-up. The extra glazing helps maintain a more consistent internal temperature, reducing moisture on your primary windows and keeping your home drier and more comfortable.
