FAQ's

Choosing uPVC over timber sash windows offers several benefits, the main being reduced maintenance. Timber windows are susceptible to rotting and paint flaking over time, which in turn requires ongoing maintenance and regular repainting. uPVC needs occasional cleaning with warm, soapy water to keep them looking fresh. 

Timber windows can also be costly, especially hardwood windows. Rose Collection sash windows are designed to replicate the features of timber sash windows truly but come at a much more cost-effective price range.

The Rose Collection provides a full range to suit every budget and requirement, from our full conservation-grade Ultimate Rose and mid-ranged Heritage Rose to our more budget-friendly and contemporary-designed Charisma Rose.

Each model in the Rose Collection has its own distinct characteristics, from mechanical joints or welded joints to different midrail sizes and a variety of optional features. All are designed to truly replicate the timeless aesthetics of a traditional sash window. To find out the specifications of each model, visit our model comparison page.

Each window can be designed to suit the current property. The optional extras on our Ultimate Rose sash model have been designed to replicate the aesthetics of a traditional sash windows meticulously.

Seahorse sash horn:

As well as our usual seamless run-through horn and no-horn option, we have developed a fully-sculptured ornate sash horn – named Seahorse for its unique design – like those used on traditional timber sashes.

Deep cill:

Timber tends to rot over time, especially at the bottom of the window where rainwater tends to collect. That is why you’ll often find that traditional timber sashes had thicker timbers at the bottom of the window.  To replicate the traditional thicker cill, you can choose our optional 50mm deep cill instead of the standard 25mm (don’t worry, our uPVC deep cill doesn’t rot!).

Staff bead:

Traditional timber windows included a staff bead on the inside to hold the sashes in place. The construction of modern-day sash windows and particularly their ability to tilt inwards for easy cleaning, means there’s no longer a requirement for staff bead. To replicate this traditional internal detail our optional staff bead can be added to Ultimate Rose windows. It has been designed to be removable to allow the tilting facility for cleaning.

Chamber cover:

Original timber sash windows have a smooth channel where the sashes slide. Due to the design of modern balanced sash windows, there are recesses in the channel where the spring balance is located. The chamber cover does exactly what it says: it covers the recess and gives a smooth appearance with just a narrow slot through which the sash is connected to the gearing. The Chamber cover comes foil matched to the window colour but does restrict the top sash tilt facility.

Depending on your chosen model, you can choose from a variety of trickle vent options. Check our trickle vent options here.

Depending on your chosen model, you can choose from a variety of hardware options and colours. Check out our dedicated window options.

All our sash windows can be foil-finished in our standard colour range. Check out our standard colour guide for a full list of options. As we own our own foiling facility, we can also foil your window in a variety of other popular foils. For other colours, you can have your windows sprayed with any RAL colour.

All Rose Collection sash windows have size limitations of 1500mm width X 3000mm height. For larger windows, there are also limits on tilting and sliding based on a combination of weight and size. Please contact the team for more information.

Ultimate & Heritage Rose models are predominantly manufactured using REHAU profiles, although Ultimate Rose has some profiles that are unique to Roseview.

The Charisma Rose model is manufactured using Eurocell profiles. You can find more information on the profiles we use on our sustainable future page.

Astragal Bars:

Astragal bars are fixed on the windows glazing internally and externally using our uniquely designed aluminium carrier bar. This makes the bars much more secure than alternative methods that simply stick the bars to the glazing using taped clips. 

Our Ultimate Rose and Heritage Rose windows use authentic, fully putty-line chamfered bars on the outside, with ovolo inside the frame, whereas our Charisma Rose sash windows use cottage-style ovolo bars inside and out.

Internal Georgian bars:

You can also opt for internal Georgian bars set inside the sealed glazing unit. Available on every model, our internal Georgian bars are available in 18mm or 22mm options.

If you’re seeking a traditional design, we recommend choosing astragal bars over internal Georgian bars for their superior aesthetic appeal, which is in keeping with traditional window styles.

To discuss how you should style astragal bars on your windows – please visit our contact us page.

If you are looking for a specific period style, we can recreate popular styles such as Georgian (6-over-6), Victorian (2-over-2) , Edwardian (6-over-1). All models in the Rose Collection can also be styled to your own custom configuration.

For more information on astragal bar styles – visit our dedicated window options page.

Rose Collection sash windows require very little maintenance – just an occasional clean using soapy water and a sponge. For more information on how to tilt our windows for cleaning, check out our  Operation & Maintenance Guide.

All Rose Collection models can be coupled together using our 3mm joiner, which joins two or more external frames together.

For Ultimate & Heritage Rose models you can also order our unique slim mullion option which shares the same outer frame and cill and reduces the joined section from a combined 135mm wide to 85mm.

Our windows can be designed to suit a variety of variations, such as arches with gently curved heads, true arches, rakes and angles or gothic arches. For more information on arched or shaped windows – visit our dedicated specials page.

All Rose Collection sash windows boast A-rated WER ratings as standard. Thanks to their multi-chambered profiles and high-quality double glazing, all models provide excellent insulation that keeps properties warm in the winter and cool in the summer.

Each sash window is also manufactured to a U-value of 1.5 W/m2K as standard, with optional upgrades to reduce the U-value even further to 1.4 W/m2K by improving the glass specification.

You can also reduce the U-value even further by using ThermoVFlex, which lowers U-values to 1.2W/m2K on Heritage and Ultimate Rose sash windows without the need for specialist or triple glazing.

In 2022, building regulations changed to improve the efficiency of new and existing buildings. These include changes to Approved Documents F (ventilation) and L (energy efficiency). We have developed a specific guide to better understand the changes that affect sash windows. Visit our guide to new building regulations.

In short, yes, you can. However, there are restrictions that may apply to your property in a conservation area, including Article 4 Directions. There are also exclusions to subdivided properties. These include the likes of flats, commercial buildings and properties that have had a change of use (such as barn conversions). For more information, check out our dedicated conservation & planning page. You can also check out our article on demystifying conservation.

For over forty years, Roseview has led the way in manufacturing the most authentic timber-alternative sash windows. In fact, our sash windows have previously been approved for use in hundreds of conservation areas around the UK. Our conservation-grade Ultimate Rose provides the ideal solution when looking for sash windows suited for conservation areas. For more information – visit our dedicated Conservation page.

By default, all building works require planning permission. However, many minor works are included under the framework of permitted development. In most cases, permitted developments allow windows and doors to be replaced like-for-like without planning permission, as long as the replacements have a ‘similar visual appearance’. This term is key as it does not specify specific materials.

Many other factors, such as Article 4 Directions, remove permitted development rights. We always recommend checking with your local planning authority to see if the property requires planning permission. For more information, visit our dedicated conversation page.

If you require planning permission, you will need to contact your local authority to get approval. Our team is on hand to answer any questions you may have. We have also created a draft conservation statement that you can use as a supplement to your planning application. Visit our dedicated conservation page to download our example conservation statement to help assist your application.
