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.

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.

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.
