Atlas Square/Pyramid Lantern (1000mm x 1000mm) In White - Double Glazed - Self clean Solar Blue

Ventilation is not usually required with roof products, as this is taken care of mainly through windows, doors and air bricks. If ventilation in the roof is required (or is your preference), then a lantern is the best option as we have a choice of manual and remote-operated roof vents. Roof lights are always fixed and cannot be opened.

Our roof products are designed to be easy to fit for people with DIY experience and experienced tradesmen. Roof lights come pre-glazed for easy installation and roof lanterns come with illustrated instructions and clearly labelled, pre-cut parts. However, it is always wise to have the products fitted by somebody with experience present.

Please also remember that the product can require several people to lift the heavy glass units, and working at a height always requires appropriate health and safety measures are observed.

Yes, we can offer marine-grade upgrades for customers who live within 10 miles of the coast.

The best energy rating we can offer is a roof lantern with 44mm triple glazing, which can achieve a U value as low as 0.6.

The glass should be cleaned in the normal way, with a soft sponge and warm water with mild detergent. For roof products with restricted access, we offer self-cleaning glass as standard, which has a coating to help remove dirt particles when rainwater hits it.

Planning permission is not typically required to install a roof lantern or roof light. Both products are usually considered as permitted development providing they meet the following criteria:

• The roof lantern/light must not protrude any higher than 150mm from the existing roof plane.
• The roof lantern/light must not be any higher than the highest part of the house roof.
• Any side-facing windows must be obscure glazed and any openings must be 1.7m above the floor.

Always check with your local council or building authority, especially if you live in a conservation area or listed building.

For new builds and extensions, the products will need building regulations consent and must meet the current recommended minimum requirements. Further accreditations such as document Q, PAS24 and Police Approved may not be essential, but check that your architect or authority have not specified this.

Lean-to roofs are not part of our standard range, but we can supply them by special request. Please refer to our Atlas brochure for information on lean-to roofs. If you are interested in a quote, please send it to our sales team.

It’s important to choose a reputable roof product as remedial work can be problematic after installation. Our roof products are not only considered the strongest on the market, but they are also renowned for their ease of installation with clearly labelled parts and illustrated instructions.

Contemporary Roof Lantern: No roof bars between the four sections, which provides maximum glass area. However, there is a size restriction of 1500mm in width and 3 metres in length.

Regular Roof Lantern: A more traditional look, with roof bars in each section. The number of bars depends on the overall size, and these can be made in larger sizes up to 4 metres in width and 3 metres in length.

Maximum sizes are up to 1400mm in width and 6 metres in length.

Maximum sizes are up to 4 metres in width and 3 metres in length for regular roof lanterns. For contemporary roof lanterns, the maximum sizes are up to 1500mm in width and 3 metres in length.

This size best suits our lantern profile, which has an internal groove just the right size for your plasterboard to fit flush, leaving a clean and professional internal finish.

A tie bar is an internal T-shaped bar that may be required when a roof exceeds a certain size. It ties the rafters together and further supports the roof structure to prevent excess load or collapse.

Our software calculates when tie bars are required. Here are the general rules for roof lanterns based on size:

• Up to 2.5 metres wide - no tie bars required.
• Up to 3.8 metres - hidden tie bar.
• Up to 5 metres (depending on design) - rafter tie bar.

Any order for a roof lantern will receive a technical CAD drawing for your approval. This is not usually required for roof lights.

Roof lanterns come as standard with a 25-degree pitch, and roof lights are recommended to be fitted on a 5-degree pitch. We can alter these depending on your requirements but recommend these pitches.

Yes, we can offer roof vents that are either manual opening with a pole or electronically controlled with a remote control or wall-mounted switch.

Both options provide an abundance of natural light. Key differences:

Rooflights: Subtle, non-opening, cheaper but may require more units.

Lanterns: Feature piece, central focus of a room, can include roof vents for ventilation.

Yes, a skylight is the American term, and some refer to a roof light as a skylight. Our product is referred to as a flat roof light, non-opening and installed at a slight pitch.

The Atlas roof lantern is the strongest on the market with ultra-low sight-lines, making it more attractive than competitors. The roof bars are slimmer at only 40mm, giving a more contemporary look with more visible glass area.

Glazed roof products bring in natural light and create a feeling of light and space, almost standard in rear extensions. They are highly recommended for creating an open-plan, expansive feel in your home.
