Heritage Collection


The Heritage Collection from South Lakes Windows Ltd is a range of elegant Upvc windows and doors that feature the characteristics and charm of period timber windows.

Every window and door shown is manufactured, not with timber but using a specialist range of advanced UPVC profiles. Considerable care has been taken to capture the charm and elegance of timber, even down to the textured woodgrain finish, but combined with the advanced low maintenance qualities associated with modern day PVC-u products.

This versatile collection includes a number of options from the fundamental choice of sash style through to your choice of finish from the subtle colour palette. The result of this is a range that will suit a multitude of property styles.

Choice of Three Sash Options

In order to cater for a diverse range of property styles, the upvc Heritage Collection offers you the choice of three sash options.

All three options utilise the same thermally efficient chambered outer frame and all provide a beautiful traditional looking white woodgrain ovolo sculptured finish on the inside.

All options include dummy sashes on any fixed windows, providing a balanced appearance and equal sight lines between your chosen configuration of fixed and opening windows. All options are also available in the same Heritage range of colours and with the same optional finishing touches such as Georgian bar detailing and your choice of elegant furniture.

Sash Cross Section

This however is where the similarities end and the clear distinction between the three sash options becomes apparent. Whilst the rebated sash lips over the outer frame giving a picture frame effect, the flush sash remains in line with the outer frame offering a slimmer appearance. You then have the option of Flush M, offering mechanical butt joints to the outer frame and sash for the truly authentic timber look.


The Heritage Collection is designed to offer an innovative, low maintenance yet high performance alternative to traditional timber joinery.

A crucial design aspect that helps to create the timber look is the use of ‘dummy sashes’ where no opening window is required.

An example of this is pictured here where the two outer sashes are designed to open out but the middle sash does not. A ‘dummy sash’ is used in the middle to give the impression of an opening sash and consequently keep the appearance identical to the two outer opening sashes. The use of ‘dummy sashes’ is standard across the Heritage Collection and ensures a balanced design with equal sight lines throughout.

Here we see another great illustration of Heritage ‘dummy sashes’ from both outside and inside perspective. As you can see by the positioning of the ornate Monkey Tail handles, the two outer sashes are both opening windows with the centre sash fixed.

This installation also shows how Heritage Windows provide a subtle splash of colour outside (in this case Agate Grey) but always maintaining a neutral fresh White Woodgrain finish on the inside.

For a cottage style appearance, the Heritage Rebated window, finished in one of the available subtle woodgrain colours such as Ice Cream or French Grey will add charm and character to a property.

Optional Georgian Bars will enhance the character further and provide a strong sense of period identity, particularly important if you are replacing ‘like for like’ and trying to emulate the traditional timber joinery that you are replacing.

Elegance and simplicity with Heritage Flush Sash

Here we have a beautiful example of Heritage Flush windows, installed in a four bedroom detached property in a Nottinghamshire conservation village. (Not a South Lakes Windows Installation)

The property is less than 20 years old but has been designed to be in keeping with the style of the sixteenth century manor house in whose original driveway the house has been built.

The owners knew they needed to replace the original windows and wanted to give their house the wow factor but were also mindful of the need to be sympathetic to the style of the older properties surrounding them in the village. That’s when they started looking at woodgrain effects and were introduced to the Heritage Collection. They opted for a Heritage Collection flush casement style in Ice Cream woodgrain on the outside face to create the impression of wooden windows. As with all Heritage woodgrain windows, the inside face is kept to a neutral White Woodgrain finish for a bright and spacious feel and to complement neutral décor.

To the front, the owners chose to have two horizontal Georgian bars to add character to the property and to reflect the traditional styles of many of the houses in the village. To the rear they wanted an uninterrupted view of the garden, so decided not to have Georgian bars on those windows.
