Your questions, answered

What is a U-value?

The U-value of a product measures how effective its insulation properties are. The lower the U-value, the better the insulation. As a guide, a standard double-glazed window typically has a U-value of 2.8 W/m².

What is a thermal break?

A thermal break is a material with low thermal conductivity placed between conductive materials to reduce or prevent the flow of thermal energy.

In our products, these thermal breaks include resin, silicone and styrofoam, which separate the conductive aluminium components to provide superb thermal insulation

What sizes should I measure?

The measurement we work from is the INTERNAL hole size — so measure the size of the hole.

If you want to leave the black aluminium frame of the skylight showing, then include finish plasterboard. If not, then give us the size of the hole before plastering.

Our skylights are designed using a 70mm wide aluminium kerb detail profile. This can sit on a minimum 70mm wide x 25mm deep timber frame.

Can I see your products in person?

Yes, our Leicester showroom welcomes both trade and residential customers. Here you can see our range of products and our manufacturing facilities. Our experienced sales team will be on hand to answer any questions and demonstrate the product features, such as the manual or electric opening roof vents, which provide natural ventilation.

How quickly can I get my order delivered?

Bespoke products are usually delivered to your site within 10 working days.

This timescale can be improved upon by a few days if you choose to collect your products from our Leicester factory.

For super-fast delivery, choose from our ex-stock flat-roof skylights, which can be delivered within 1–3 days from when you place your order.

Can I collect from you?

Yes, if you would prefer to collect direct from our Leicester factory, please let us know when you place your order.

What are your payment terms?

Payment terms for normal orders are strictly pro-forma, using Visa, Mastercard, bank transfer, WorldPay or Paypal.

Paying via Visa or Mastercard not only insures the product and your risk, but also gives you up to 60 days free credit, depending on which card you have.

For larger orders, or orders that do not require immediate delivery, we offer a 50% deposit option with the balance being due just prior to delivery or collection.

Can I buy the Slimline roof lanterns in kit form?

Yes, this is the best option to avoid any lifting issues and self-assembly is very easy to do.If you prefer, we can factory assemble/glaze or build the skylight and glaze it up on your flat roof for an additional cost. This is recommended for larger roof lanterns and skylights.

Are the Slimline and Pyramid skylights available in white?

Yes, we manufacture the slim aluminium glazing caps in satin white, slate grey, satin black and with dual white internal combinations.
