One of the questions we’re asked most often in our showroom is:
“What’s the difference between Residence Collection R7 and R9?”
It’s a fair question. At first glance, they have a lot in common. Both are beautifully engineered flush sash window systems. Both combine the appearance of traditional timber with the benefits of modern materials. Both offer excellent thermal performance, impressive security and very little maintenance.
So, which should you choose?
The honest answer is that there isn’t a “better” window. There’s simply a better choice for your home.
One thing we’re always keen to highlight is that it never starts by recommending a particular window. We start by looking at the property itself. The age of the house, its character, the proportions of the existing windows and the overall style all help determine which system will look and perform best.
It starts with what each window was designed to do
Although they sit within the same collection, the Residence Collection R7 and R9 were created with slightly different design goals in mind.
The Residence Collection R9 was developed to recreate the appearance of traditional 19th-century timber windows. With its 100mm deep frame, decorative internal profile and carefully considered heritage detailing, it’s designed for homeowners who want an authentic period appearance without the maintenance associated with timber.
The Residence Collection R7, on the other hand, offers a cleaner, more contemporary interpretation of the flush sash window. Its 75mm frame and flush internal finish create simpler sightlines, making it an incredibly versatile choice for a wide range of property styles.
Both are unmistakably part of the Residence Collection family. The difference lies in the look you’re hoping to achieve.
The biggest visual difference is often on the inside
When people compare replacement windows, they naturally focus on how they’ll look from the outside.
But when you live with your windows every day, it’s the inside you’ll notice most.
The Residence Collection R9 has a decorative internal profile inspired by traditional timber joinery. Combined with heritage hardware options, such as Monkey Tail and Pear Drop handles, it creates an authentic period feel throughout the room.
The Residence Collection R7 has a flush internal finish with cleaner lines, giving it a simpler, more understated appearance. It still has plenty of character, but it’s less ornate than the R9.
Neither is better. It’s simply a matter of which style feels most at home in your property.
Looking beyond the specifications
It’s easy to compare frame depths, chamber numbers and glazing options.
What’s much harder is knowing which window will actually suit your home.
That’s why Tim doesn’t arrive with a favourite product in mind. He starts by looking at the property.
A Victorian cottage with original features may benefit from the additional heritage detailing of the R9. A more modern property might suit the cleaner styling of the R7. Sometimes, another window system altogether is the better option.
Our job isn’t to recommend the most expensive window or the one with the longest specification sheet. It’s to recommend the one that complements your home and the way you live.
Performance matters too
While the styling is different, both the Residence Collection R7 and R9 have been designed to deliver outstanding everyday performance.
The R7 features a seven-chamber profile, while the R9 has a deeper nine-chamber profile. In both cases, the multi-chamber design contributes to excellent thermal efficiency when paired with the appropriate glazing specification.
Both systems are available with double or triple glazing, helping to improve comfort, reduce heat loss and minimise outside noise.
Whichever you choose, you’ll benefit from modern security, low maintenance and excellent energy efficiency.
