Atlas Aluminium Glazed Roofs, Lanterns and Orangeries
The Atlas roof system is the strongest, best looking and most thermally efficient roof on the market

Three Atlas roof construction options

provide the perfect look roof for any property style or scheme.

Most competitors insist on a rod tie bar at eaves beam level. But not Atlas. A choice of hidden, rafter or rod tie supports provides the ultimate luxury and flexibility to create the roof you want.

Unrivalled strength

Extra strong rafters mean the tie bars can be set higher, guaranteeing excellent headroom and no intrusion into the living area. Even in large buildings the roof structure remains remarkably minimal, creating a sense of clear, free space under the eaves.

Increased roof strength means the design aesthetics and clear sightlines achievable using the slim Atlas profiles remain unmatched by any other manufacturer, creating a roof that can suit any dwelling.

No boss and hoods - Looks and strength

Using the benefits of slimline technology Atlas have combined good looks, outstanding strength and intelligent detailing, to create one of the finest looking products available for conservatory and orangery installations.

The versatility of the aluminium box section rafters and creative design solutions have removed the requirements for outdated bulky hood covers on lantern roofs and Edwardians


Turn a roof into a contemporary architectural feature. The strength-to-weight ratio of Atlas aluminium profile offers dramatic roof spans without tie bars

Minimal intrusion

Contemporary schemes often dictate minimal intrusion – for instance to maximise open-plan layouts and create high roof spaces. Large spans with Atlas can be achieved easily without the need for unsightly bolster bars

Wide range of colours

The Atlas box rafter appearance, similar to a curtain walling system, is available in a range of RAL colours. For a modern finish, flat roof rafter caps are available in PVCu or aluminium


Classic proportions thanks to modern engineering. Create the appearance of a timber frame roof with a slimline profile

A perfect match

Traditional schemes often feature timber frame conservatory builds. When foiled, the Atlas rafter system is almost impossible to distinguish from wood at-a-glance. In fact it’s so convincing that several timber company customers regularly fit Atlas roofs on their own timber frame conservatory builds

Attention to detail

Fully featured PVCu or aluminium roof rafter caps offer the appropriate finishing detail

Twice as efficient

A U-Value (W/m2K) is simply a measure of heat loss from a building structure – for instance a roof, or a window and frame. A high U-Value means thermal insulation is poor whilst a low U-Value indicates a good thermal insulation

As a glazed roof is made up of both glass and rafters, you want low U-Values from both. High performance glass is usually rated at 1.1 or 1.2 U-Value, but the value of roof rafters vary considerably. The Atlas rafter has a U-value of 1.5 W/m2k which is twice as thermally efficient as its nearest competitor (which are over 3)

When using doubled glazed Low e glass (U-value 1.1W/m2k) the overall Atlas roof has a U-value of as low as 1.2 W/m2k

Triple Glazed

The fundamental design features and the strength of the Atlas roof system, enables the roof structure to withstand additional loads, such as the introduction of triple glazing

It has been well documented that to achieve the best thermal properties for triple glazing, the glazing cavity between the glass panes should be 16mm. This results in a 44mm triple glazed unit which has superior U-values, compared to 28mm or 36mm triple glazing

The Atlas lantern and Lean-To has been designed to be glazed with 44mm units, which have a U-value as low as 0.6 W/m2k

The Atlas roof rafter U-value improves to 0.95 W/m2k when glazed with triple glazing

When using triple glazing Low e glass the Atlas roof has an overall U-value of as low as 0.7 W/m2k
