Triple Glazing for Composite Doors

Some of our composite doors use triple glazing, which offers benefits over our standard double glazing. These styles make use of came work and textured glass, as well as bevels or foil.

What is “came”?
This refers to the lead used to join multiple pieces of glass together. This technique has been used in stained glass window making for centuries, allowing the creation of intricate and breathtaking designs, by combining different shapes and colours or patterns. Nowadays, it is also used in door glass for a similarly striking effect.
How does triple glazing compare to double?
Both are beneficial to energy efficiency due to the use of warm edge spacer bar technology and multiple panes to reduce internal heat loss, but naturally triple panes can do more than double.
Advantages
Easier maintenance
Because the lead is sealed within the central pane, there is no need to be concerned about cleaning a triple glazed unit as there would be with a double, where the lead is exposed and meaning more refined cleaning is necessary.
More energy efficient
If two layers can reduce heat loss better than one, then three layers will provide even more reduction.
Greater noise reduction
Just like they reduce the escape of heat, multiple layers also reduce the entrance of sound.
Disadvantage
No backing glass options
It is not possible to choose a backing glass option for triple glazing. While these styles do offer a high degree of obscurity, one may need to consider their requirements if privacy is a concern.

What triple glass designs do you offer for composite doors?
As stated, they all use lead sealed within the panes, and a combination of textures, bevels or coloured foil.
Cameo
Features
- Zinc came
- ‘Square’ diamond bevels with clear backing and gluechip centres
- Stippled texture with hammer chiselled borders
The small rectangle, mid and twin vertical glass panels have one, two and three diamonds respectively running vertically down the centre, flanked by zinc came lines, and with crisscrossing lines from each bevel. For the twin vertical, the style is known as Trio Cameo.
The half-moon features a single diamond, and is bordered by chiselled glass, with the bottom corners, top and bottom connecting to the arched came half-moon.
The half-glazed has three sets of horizontally adjoining trio bevels running from top to bottom, joined by zinc lines. They are within a chisel textured border, with lines meeting the outer edges, and the corners of this border curved. The curves touch the glass edges, while two sets of vertical lines touch between the edges and border.

The half-glazed arch is similar to the straight-shaped half glazed, except for the top trio bevels replaced by a single, and the border curved to match the glass’ shape.
The traditional arch (also known as a Craftsman design) is like the half-glazed, but focuses on the central trio of bevels.

Christie
Features
- Zinc came
- Small ‘thin’ diamond bevels with clear backing
- Stippled texture
The twin vertical has left and right variants. In the instance of the left, an offset vertical line runs the full height, with a bevel each near the top and bottom, intersecting the width with a horizontal line. Within the rightmost ‘area’, another bevel in in its centre, with lines moving from its points to the outer came and right edge. The right version of this glass is a mirror of this design.
The mid-sized and small rectangles focus on the central section, but with the orientations reversed – the left’s bevel on the left, and the right one’s on the right.

The half-moon is symmetrical, a small diamond in the centre flanked by vertical came and lines emanating from its points. Outside these flanking lines is a horizontal line on each side set a quarter from the bottom.

Duo Diamond
Features
- Zinc came
- Thin diamond bevels with clear backing, and gluechipped centres with starbursts
- Stippled texture
A simple but elegant design, two evenly spaced diamonds run vertically down the middle, with crisscrossing came from each. The mid-sized and small rectangle versions focus on a single diamond, slightly larger in the latter.
The half-moon has the normally horizontal line curving to the shape of the glass’ arch shape.


Grace
Features
- Zinc came
- Curving diamond, oval and curved joining bevels with clear backing and gluechip centres
- Hammer chiselled inner texture and gluechip outer texture
This twin vertical design features a diamond with curved edges and central starburst, an oval each above and below it, and pairs of curved bevels completing the overall shape. Lines emanate from the tips of this cluster, and near the top and bottom are outward curving lines to separate the inner and outer textures.


Oasis
Features
- Black came
- Clear-backed blue and yellow foiled floral design with a red centre, and two yellow foiled circles
- Stippled inner texture, chiselled outer texture
The twin vertical features the flower in the centre, and a yellow circle each halfway above and below it. The flower is flanked by full-height a line on each side. Each of the circles has straight lines coming from the four points, and two more to the top and bottom. The mid-sized is the same but with reduced height. The small rectangle focuses on the lower circle, with the stipple effect above and larger chisel effect below.

The half-moon consists of the flower in the centre, and horizontal dark came meeting a yellow circle on each side, with one line going upward and three downward from each. The upper half has stippling, while the lower has chiselled glass. The traditional arch has three lines above and below the circles, and the outside the foil is entirely chisel textured.

Olympic
Features
- Zinc came
- Dark square bevels with clear back
- Finely reeded texture
The mid-sized panel has two vertically aligned bevels evenly spaced across the height, with twin lines running down their sides, and horizontal lines coming from the centre height of each of these squares. The small rectangle focuses on one of these squares.
The half moon has one of these bevels and pair of twin lines in the centre, along with the same horizontally central line. To either side of the central bevel and lines are two sets of lines in the same width.


Sycamore
Features
- Zinc came
- Tall diamond and ‘square’ diamond bevels with clear backing
- Stippled inner texture, gluechip outer texture
The twin vertical has a central cluster of four ‘square’ diamond bevels, with a taller bevel each above and below it. Straight zinc came connects the points of the outer bevels and cluster together and to the edges of the glass. Furthermore, the cluster and each bevel are joined by a pair of symmetrical curved lines, within these a stippled texture.
The mid-sized panel has a single tall diamond instead of the cluster, and no other bevels, with the curved lines meeting the vertical.


Tate
Features
- Black came
- Hammered texture rectangle
- Stippled texture
The twin vertical shaped glass panel has two strips of dark came meeting twin horizontal lines at the top and bottom, and stopping at the outer-most of these. These create small rectangular shapes with a chiselled texture, and the centre has twin horizontal lines of the same size to create a third textured rectangle. From the top- and bottom-most lines, a central line moves to the glass’ edge. Slightly above and below the central rectangle, twin lines move from the outer vertical came to meet the glass edges.

The mid is similar, but cutting out the central section. The mid, half-moon and traditional arch versions focus on the top area, with the textured rectangle in the centre and lines meeting the edges at required lengths.

Trio Diamond
Features
- Zinc came
- Large tall diamond with starburst and small tall diamond bevels with clear backing
- Gluechip texture
The twin-vertical and mid-sized versions have a large central bevel, and a smaller bevel each about two-thirds above and below, with came from each points connecting these bevels and touching the edges.
The half-glazed version, instead of one large diamond, has a cluster of four. The design is framed within a box of came, with extra lines touching the edges to the corners of this ‘frame’. The traditional arch flips the design to a horizontal orientation and focuses on the diamonds, no ‘frame’ present.

The half-moon has a single central large diamond with outward came, while the small rectangle version uses the smaller bevel.

What other ways can I enhance my composite front or back door?
There are several ways to customise your new composite to truly make it unique.
Choose from our different finishes, from a modern anthracite grey to a traditional oak. This range of colours is also available for the inside, though most of our customers leave this as white in order to maximise natural brightness in their hallways.
We even offer a bespoke colour service should you have a specific RAL colour in mind.
Hardware
We offer a selection of handles, whether you’re happy with a traditional lever, like the standard Balmoral or curved swan, or need something different, like the 1930s inspired heritage lock, or even bar handles (where door styles permit). Extras, such as a letterplate, knocker, spyhole, and even house numbers, come in various finishes just like our handles, giving you matching furniture.

Side panels and toplights
If you require a side panel, flag window or toplight (straight or arched), we can add these for you, using the same profile and colour as your new composite’s frame.
