Reynaers Heritage Collection

More recently, Reynaers has introduced the Heritage Collection. However, it lacks anything new in steel-inspired windows and doors. It simply comprises Slimline 38, Slimline 68 and MasterLine 8. All of these are available with a range of profiles giving a modern, classic or Deco style frame design.

If you are in the market for steel-look windows, Reynaers will serve you very well and arguably come with more design options than the popular Aluco system and Smart Systems Heritage range. But it is significantly more expensive, and their steel-look residential doors don’t offer the authentic styling of other brands, not even featuring the lock backplate typical of Crittall® doors.

Best for: Steel look windows in the Reynaers brand and if the design features of original metal windows aren’t essential.

Reynaers Aluminium Windows – how to choose and where to buy

For most residential installations, Reynaers SlimLine 68 will meet your needs as slim, high-quality opening outwards casement windows. There is not need to look at the other models on offer.

For new-build homes needing the lowest possible U-Values MasterLine 10 provides the obvious solution. That said, such is the flexibility of Reynaers aluminium windows, you can get to very low U-Values with their other products, apart from the CS77, depending on the glass specification used.

CS77 is the go-to performance window when you want total integration with your doors, aren’t bothered about the slimmest windows, but want the reassurance of a tried and tested window. CS77 is designed and made to perform.

MasterLine 8 is designed in such as way as to meet all manner of requirements, whether it is styling, frame options, large or small windows, and integration with a great range of doors, including designer entrance doors. Where you are not constrained by budget, Masterline 8 windows are very impressive.

As good as Reynaers aluminium windows are, you won’t find every Reynaers installer or manufacturer making or offering every model. MasterLine 8 is outstanding in its appearance, functionality and specifications, but very hard to get to see in person. Viewing Reynaers windows is therefore not easy, and a trip to the Reynaers Showroom in Birmingham is a good starting point. Express Bifolds in Leeds, Scotland, Surrey and Essex provide Reynaers aluminium windows under their own brand name, although again they do not make every model.

Buying a Reynaers window is recommended because the reputation, quality and specifications or this brand go much further than anything by Smart Systems, Origin, Aluk, Sheerline and others. Only Schüco windows come close. Your windows will perform, last for years and look great with minimal maintenance.

The entire Reynaers aluminium windows range is very advanced, offers standard or very high window specifications and is accompanied by bifolding and sliding doors. It can be difficult finding good Reynaers installers, but you can get in touch and we can help with details of those near your area.
