Do you do the installation as well?

Do your skylights open and close?

Yes, we offer fixed and openable skylights.

What is the max Ug-Value?

The maximum value our skylights has is 0.9 W/m²K.

Can I have blinds on my 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.

Will it be noisy if it rains?

We provide skylights that are double and 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 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.

Where are your skylights sourced from? Are they made in the United Kingdom?

Our skylights are manufactured in Europe.

How Can I Pay for my Skylight?

We accept PayPal, Credit and/or Debit Cards (Stripe), Google Pay, Amazon Pay and Direct Bank Transfer. You will see these payment methods offered to you upon check out. Unfortunately, we only accept payment in advance.

What pitch should my flat roof skylight be?

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.

What is the lead time for items in stock?

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.

Yes, just let us know any instructions for delivery or delivery dates in the “notes” box during checkout.

Can I apply my own tint?

You can order a tint for your skylight by selecting the option on our custom calculator, we offer a green or blue tinted option.

Will the window need assembling upon arrival?

No, the skylights arrive ready to install (don’t forget to order your accessories separately so you can be ready to go).

Double or Triple Glazed?

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.
