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.

This all depends on the size of your new loft or extension roof. The skylight or skylights need to be positioned in such a way as to allow a maximum amount of light in the areas you want. Not forgetting leaving space for ceiling lights. Wall lights may be an option if a larger skylight is your main priority.

The larger the skylight the more natural light and panoramic views you will have. As London is mostly cloudy and we lack sunshine through out most of the year, we recommend going for a bigger size skylight or more than one skylight as this will save you turning on your lights through out the day. The deeper and longer your extension the less light you will have throughout the day if skylights are not installed.

The largest size skylight we could make would have to be a custom order and be quoted for in advance for approval by you. However the size we could make is 4500 x 2000 mm this is the max as above this size transportation and weight tends to become specialised.

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 6°. It is worth it to spend a few extra minutes before applying the silicone to run a water test.

We offer Double and Triple Glazed Units.

Yes you can have them installed once your skylight is fitted.

Аs the installation of blinds behind the glazing increases the risk of Thermal Stress Glass Breakage, we advise you to install the blinds at a min. distance of 150 mm from the glass.

They are all popular options for introducing daylight into your living areas. In short, difference is:

As per BS EN 14351-1:2010, A roof window is a roof glazing installed in the same orientation and ‘in plane’ with the surrounding roof, typically at a minimum 15° pitch.

“Skylight” and “Rooflight” are generic terms and you can see the same product with either of those names. They both refer to roof glazing for a ‘flat roof’ installed on an upstand, and are not in the same plane as the surrounding roof.
