Roto Pitched Roof Window Center-Pivot 114 x 118 cm White Painted Timber
Pivot roof windows with built in thermal insulation (WD block)
The WD block system enhances the thermal efficiency of roof windows, notably at vital connections with the rafter framing, bringing several benefits to your living space:
Better Insulation: Targets the entire perimeter and height of the window, focusing on areas vulnerable to thermal loss and moisture, to create a warmer and drier interior.
Heating Cost Reduction: Incorporating the WD block significantly curtails heat escape during cold months, leading to considerable savings on heating bills.
Enhanced Thermal Performance: The system boosts the window's energy performance by up to 15%, ensuring heightened thermal efficiency.
Warmth at Critical Junctions: Increases the temperature by about 5°C at crucial contact points, reducing condensation and enhancing indoor comfort.
Flawless Fit with Your Roof: Ensures a tight, energy-efficient connection, allowing seamless integration of the window with the roof, thus improving its aesthetic and functional appeal.

Skylight Windows
Installation Guides

Say goodbye to complicated installations!
Our skylight installation guide provides clear and concise instructions to help you easily install our range of roof windows. From flat roof windows to pitched roof windows, our guides guide you step-by-step through the process, ensuring a hassle-free installation.
Structural opening – provided By builder
Bear in mind our Skylights sizes are the sizes of the bottom (internal) glass panel. The top panel is stepped by 100mm on each side, and the overall externally visible size is 200mm bigger in both directions:
For example, only in this guide will we present installation sketches for a Skylight 600mm x 600 mm. For all other sizes, we provide installation sketches in the gallery of each size separately.

Double/Triple Glazed Skylight 600x600mm has the following sizes:
The upstand should protrude a minimum of 150mm above the roof level
A minimum pitch of 8-10 degrees relative to the horizon must be provided to avoid water pooling in the middle of the glass panel (for every metre of Skylight a 10cm fall is required). It is worth spending a few extra minutes before applying the silicone to run a water test to ensure the water is not pooling (even though you are installing glass it will still bend in the middle). The internal distance upstand to upstand needs to be 10mm bigger than the quoted skylight size (in our example: 610mm by 610mm).

Upstand opening should allow for 5mm tolerance on each side:
Skylight Support – provided By builder
Install the support in such a way that the top of support is as follows:
-Triple Glazed Skylight – 46mm below the top of upstand
The Skylight support is a 25x50mm (2”x1” ) timber:

Weather the upstand
Apply the roof covering material to cover the external face and top of the upstand.
Make sure all surfaces where the silicone will be applied are clean of dirt, dust, moisture, etc.
- Apply the foam rope on top of the 2”x1” timber support to level off any discrepancies which will prevent any pressure and stop cracking on the bottom glass laminated pane. THE WARRANTY WILL BE VOID IF A FOAM ROPE IS NOT USED.
- Apply, generously, on top of the upstand weatherproof sealant, usually, 1 tube is enough for 6 linear metres.
- Lower the skylight with suction cups, and make sure you check the load on each cup.
- Apply waterproof sealant on the underside of the overhang and smooth it over once more to make sure it is watertight.
Once you finish weathering the upstand, you are ready to install the Skylight.

Yes, you can have them installed once your skylight is fitted! As the installation of blinds behind the glazing increases the risk of Thermal Stress Glass Breakage, we advise you to install the blinds at a minimum distance of 150 mm from the glass.
All our Skylights come triple-glazed which provides optimum sound insulation. This, in turn, would help minimise any rain noise. The more panes of glass, the better the noise resistance and the greater the distance between each glass, the better your sound insulation will be. All our skylights are designed with these factors in mind. We offer triple glazed skylights with 6mm toughened safety glass as standard and a generous 15mm gap between the panes and bottom. Panes are 8mm thick reducing noise to maximum.
Our skylights are manufactured in Europe.

It is important to have your skylight installed at a slight angle relative to the horizon to allow water to run off the glass and avoid pooling. We recommend setting the rooflight at an angle of 45°. It is worth it to spend a few extra minutes before applying the silicone to run a water test.
Lead time depends on the size of the unit and the exact location in the UK, please add the item to your card and your delivery postcode and you will see all delivery options to your location-keep in mind that you will not be charged at this stage.

No, the skylights arrive ready to install (don’t forget to order your accessories separately so you can be ready to go).
Triple Glazed skylights tend to have a better U-Value and Noise Resistance. What this means is that a triple glazed skylight will have better noise reduction properties if you live in a noisy area. The lower U-Value benefit of them is that they have less heat loss. So if you plan on having a larger skylight or more than one skylight on your extension letting in more natural light we would recommend going for triple as it will save you on your energy bills and lose less heat.
Double Glazed Skylights tend to be lighter in weight and easier for installations however they are not as good on heat loss and noise reduction as triple.
