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.
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.
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The versatility of the aluminium box section rafters and creative design solutions have removed the requirements for outdated bulky hood covers on lantern roofs and Edwardians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
Classic proportions thanks to modern engineering. Create the appearance of a timber frame roof with a slimline profile
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
Fully featured PVCu or aluminium roof rafter caps offer the appropriate finishing detail
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
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
The Atlas Aluminium Roof range of products provide a full solution for glazed roof area, it being a total glazed area, roof light or lantern
