Surface-mounted roller shutters for existing windows

Surface-mounted roller shutter VR150 can be tailored to traditional or contemporary homes with no major construction work. Easy to install on an existing window and with perfect noise and thermal insulation, we guarantee security and energy efficiency.

Largest choice of box models

The VR150 surface-mounted roller shutter offers various benefits, ranging from a classic to modern look, but always with a streamlined design thanks to the largest collection of box models, manufactured from robust aluminium as standard.

Installation on outside of house

Our surface-mounted roller shutters can be installed quickly and easily on the outside of your home, without any major building work.

Dimensions up to 11 m2

At up to 11 m2, the surface-mounted roller shutter VR150 offers privacy by reducing visibility but also prevents burglary and noise issues. They block summer heat and retain winter warmth, improving the EPC value and reducing energy costs.

A colour to satisfy every desire

Tailor your roller shutter to match the exterior joinery. The box, guide rails and bottom lath are available as standard in all RAL colours and in a great range of textured paints. There is also a wide range of colours for our top-quality slats in PVC or aluminium.

Why natural cooling

Our mission statement, “We Believe in Natural Cooling,” lies at the heart of all our efforts. We consider smart solar shading to be the most natural and energy-efficient way to block heat. Compare it to a tree providing shade: just as you seek natural cooling under the branches of a tree, sun protection keeps the sun out and your home, patio and workplace pleasantly cool. It offers natural air conditioning for your home which is healthy but also environmentally-friendly.
