Bespoke Skylight & Glazing Solutions
The Lumen Conservation Extra Light gives you the freedom to open up your roof space without the constraints of standard sizes.
We can manufacture to suit your design and offer the flexibility to work with you to achieve your requirements. For dimensions smaller than 2900mm wide or 2800mm high, we can manufacture the rooflight with a single outer frame. For larger sizes we would use our Lumen link system whereby a rooflight is manufactured to your overall dimensions using multiple frames to provide a virtually seamless row of rooflights.
Unlike the linking of the Lumen conservation rooflight standard sizes, this interlocking design considerably reduces the amount of visible steel between each casement and increases the amount of light and ventilation. Casements can be opening or fixed, have multiple or no glazing bars* and as with all our standard range, can be operated either with our hand mechanisms or electrically. *within manufacturing tolerances.
When considering how your rooflight should look, it is worth noting that fixed rooflights offer more glass than those with opening casements. If you choose non-opening roof windows you can usually have larger panes of glass or have them divided by slim (35mm) glazing bars. With opening rooflights, the frame needs to have additional metalwork to support the casement. Although this is still fairly thin you would typically have around 80mm of framework between opening and/or fixed casements. You then need to factor in the framework of the casement.
With a fixed roof window you would only frame your roof to the overall rafter dimensions. When you have opening casements within a bespoke skylight, it is necessary to have additional supporting rafters each side to support the metalwork.
We like to provide accurate prices specific to each individual enquiry. We don't have a one size fits all approach to our bespoke Lumen rooflights and so it can take up to 24 hours to provide you with a quotation.
Our team will discuss your design requirements with you before putting a written quotation together. There are many options to consider from the number of opening or fixed casements, glazing specification, paint colour and manual or electric mechanisms. Your quotation can be sent via email, first class post or both if required.
We would usually give you a call a couple of days later to check that the information has been received and to ask whether any further details are needed. You will not be under any obligation to accept a quotation and we will not hassle you to do so. We are available to answer any questions or give advice.
Should you decide to proceed with a quotation for a bespoke Lumen rooflight, we would require your instruction to proceed along with a 50% deposit. We will then write to confirm the order and instruct our design team to produce a visual drawing for you. This process can take up to 10 days. When the drawing is prepared we will contact you and email or post a copy for you to review or discuss with your builder or planning department. Once you are happy that the drawing exactly matches your requirements, we will need your written approval (usually via email) at which point we shall proceed to the manufacturing stage. If something is not correct, tell us and we will amend the information and re-issue the drawing.
The manufacturing process usually takes approximately 6 weeks. Around one week before delivery we will contact you to discuss a suitable delivery date and to take the balance payment. Once this has been received we shall arrange the transportation to your site. Your drawing will show you exactly how big your bespoke Lumen rooflight will be. Please ensure that you have adequate facilities on site to unload your delivery. Likewise, please tell us of any restrictions or difficulties that may occur during the delivery process. Most deliveries will be supplied on a vehicle with a tail lift facility however, this may not be possible for large rooflights. Your invoice and drawings will give you an exact description of what your rooflight will look like, its size and the weight. If your rooflight is large it might be necessary for you to arrange equipment to unload the delivery vehicle and lift the rooflight into position.
Once safely delivered and installed your bespoke Lumen rooflight will be protected by the same guarantee as our stock range of Lumen conservation rooflights. Full details are available on our download page.

Lumen Rooflight Maintenance
Industrial coatings are no different to the paint on your car - they need cleaning and maintaining
The powder coat to the roof light protects the metal underneath.
If you are unable to adhere to the maintenance guidelines we recommend that you speak to us about using stainless steel.

The client initially required 58 single rooflights for a large construction project in Avon. After speaking with the Lumen technical team it was agreed that we could manufacture the skylights as large bespoke items to reduce the metalwork between each casement. This would provide the client with a greater amount of Pilkington glazing therefore increasing light within the same overall roof light dimension. The client also requested that some casements would be opening while others needed to remain fixed.
Our client wanted to achieve a specific number of casements within the overall roof light dimension. Three casements were to remain fixed whilst the two opening casements needed to operate with an electric mechanism. Due to the slim width and the long length of each casement it was decided to use the KA54/250 stroke mechanism operated with a GVL8304 control panel.
This project involved manufacturing a fixed skylight to match our conservation rooflight design. Our fixed roof light design forms a dummy casement as part of the outer framework. This allows the rooflight to have the appearance of a casement whilst reducing the amount of metalwork and slightly increases the amount of glazing.
This rooflight was part of a larger order for a residential project in Surrey. The client wished to replace a number of failing aluminium frames and had a series of large individual roof lights, some opening and some fixed. This particular skylight was located in a bedroom where the client wanted to maximise the glazing area and to provide ventilation at the push of a button, utilising the KA54/350 stroke mechanism. The design was to match our Lumen conservation range to ensure a low profile against the tiles.
These skylights were used on a barn conversion and the client wanted to introduce light through a series of slim fixed rooflights. The conservation design allows the roof light to remain flush with the roof line and remain unobtrusive to the original architecture. As with all Lumen rooflights, these incorporated Pilkington Activ self clean glass with an argon gas filled cavity and Pilkington Optitherm to increase the thermal performance.
Used on a residential property in South London these rooflights where supplied with opening casements, one of which was to be used for access. As such these were designed with gas struts on one side of each roof light. All of the opening casements are operated for daily use with our solid brass winding mechanisms.
These rooflights were supplied to a client in Scotland for a residential project. Due to the large size of each opening casement, the roof lights were fitted with KA54 electric actuators. As these were produced as bespoke items, we were able to fit special brackets to accommodate the actuator within the American oak frame of the rooflight.
For this project our customer wanted a manually operated rooflight for a flat roof application. The casement can be used for ventilation on a daily basis with the brass winding mechanism but detached for access with the struts holding the casement open. The customer also chose a single glazing bar to enhance the conservation rooflight appearance. The rooflight is powder coated in RAL9005 with a coastal/marine coating and also has an American ash internal lining.
Although fairly simple in appearance, this bespoke Lumen skylight was specifically produced to suit the roof application. The rooflight is non-opening and has a dummy sash to give the appearance of a casement. We extended the fitting bracket to allow the rooflight to remain flush with the tiles yet be deep enough to reach through the insulation down to the rafters. The internal liner was extended and produced in European oak to match the customers timber framed building. The glazing specification was 4mm toughened Pilkington Activ self-clean, 16mm argon gas cavity and 4mm toughened Pilkington Optitherm S1.
This job involved two large rooflights which were used either side of the roof to allow light into a vaulted ceiling. To add the installation process each side was split into two parts which are then coupled together on site. The rooflights had an internal American ash lining with separate capping sections in American ash to finish off the internal appearance. The rooflights were powder coated in RAL9005 with a coastal/marine coating and the glazing specification was 6mm toughened Pilkington Activ self-clean, 20mm argon gas cavity and 6mm toughened Pilkington Optitherm S1.
This rooflight was produced to help a customer that required a smoke vent whilst retaining a flush fitting appearance in a conservation area. To ensure the rooflight met the conservation criteria the customer chose our low profile design and two genuine glazing bars on the casement. The available height was restricted to 1000mm so the rooflight was produced in landscape format to ensure the vent was large enough. The casement is electrically operated using side mounted rack and pinion drives.
With this bespoke rooflight, the customer had a particular multi casement appearance that he wanted to achieve. The casements are linked at 80mm apart to keep the framework to a minimum whilst maximising the Pilkington glass area. Each casement operates from its own cill mounted chain drive actuator. The rooflights were delivered to site as individual sections and linked with a capping piece during the installation. The rooflight is powder coated in RAL9005 with a coastal/marine coating and also has an American ash internal lining.
All of these bespoke projects were produced with the following specification:
3mm zintec steel frame and casement (where required)
Polyester powder coat textured paint finish to RAL9005 matt black
American oak interior liners
24mm double glazed units comprised of toughened Pilkington Activ self clean, argon gas and toughened Pilkington Optitherm.
