The most advanced UPVC windows and doors

Modus is the first major UPVC window and door system to offer the reassurance of a 12-year guarantee. And that comes without compromise on performance as it is A-rated for sustainability featuring 50% post-consumer recycled UPVC as standard. This enables us to offer better thermal performance than rivals. Combined with high security locked-in 6-chamber frame design Modus offers strength and resilience and style in abundance.

It looks as good as it performs

With its sleek, contemporary lines, Modus is an attractive addition to any home – and a sure way to boost its kerb appeal. There are eight different styles of UPVC window and door to choose from, including four sashes, French doors and tilt and turn windows. Modus comes in over 30 colours and finishes, so you’re sure to find the perfect match for your scheme.

And performs as good as it looks

If you’re looking for peace of mind you’re in the right place as the Modus system is certified with the BBA (British Board of Agrément) for thermal performance, weathertightness, ventilation, resistance to intrusion, access and durability.
