Dome Rooflight Polycarbonate Mardome Trade

Mardome Trade roof lights are a new and innovative way to reduce energy costs while making your home look great. The secret behind the Mardome Trade dome is its patented design, which directs natural light into your home while capturing heat that would otherwise go out. This makes it an ideal choice for any homeowner looking to lower their energy bill while also maximising natural lighting.

At Rooflights & Roof Lanterns, we are committed to providing our clients with the very best lighting solutions available. We are confident that Mardome Trade meets all of the essential factors to bring you a high-quality product that’s built to last.

Thanks to the use of polycarbonate, you can trust that your dome roof light will withstand inclement weather conditions without fail. So if you’re looking to improve the natural light levels in your home or business, Mardome roof lights may be the perfect solution to your needs.

Why Choose the Mardome Trade Rooflight?

The Mardome Trade dome is a patented, environmentally conscious rooflight that’s waterproof and designed to keep your home warm during the colder seasons.

These roof lanterns are made of polycarbonate, which is strong enough to withstand high winds. The dome shape provides natural light without compromising on heating or cooling. Additional benefits include:

  • The dome rooflights are waterproof, making them an excellent choice for any climate.
  • They are energy efficient, which means they also save you on your electric bill.
  • They are both functional and aesthetically pleasing, giving your home a modern look while reducing cost.
  • With the dome rooflights, natural light is maximised, so you don’t have to worry about expensive lighting bills.
  • Mardome Trade rooflights are easy to install, ensuring greater efficiency.

Dome rooflights are an excellent option for your home or business. They provide a multitude of benefits and advantages you won’t find in traditional skylights. So if you’re looking to give your space an updated look and feel, Mardome Trade has you covered.

What is polycarbonate?

Polycarbonate is a strong, lightweight material that is frequently used in rooflights. Unlike glass, polycarbonate is virtually unbreakable, making it an ideal choice for areas where safety is a concern. 

Polycarbonate is much lighter than glass, making it easier to install and less likely to cause structural damage if it is broken. In addition, polycarbonate panels can be tinted or coated to provide UV protection, making them an excellent choice for sunrooms or other areas where glare is a problem. 

Polycarbonate rooflights are an increasingly popular choice for both commercial and residential applications.

What are the advantages of polycarbonate?

Polycarbonate rooflights are a common and cost-effective way to allow natural light into the property. This is a common rooflight material used on commercial and residential properties. Polycarbonate allows more security, strength and privacy as opposed to glass. Polycarbonate is incredibly resistant to impact and nearly 250x more than glass along with polycarbonate being more lightweight.

Can polycarbonate rooflights be custom made?

Polycarbonate is only available in the set moulds on the drop-down menu and cannot be customised. The best option would be to check whether ordering with or without a builder’s upstand may suit your measurements first (Please see our fitting and measurement tab). If this is still not suitable, we would suggest you would require adjustments on site to the build to match the nearest size to the drop-down menu based on whether this is with or without an upstand selected and then to build according to the correct measurement. Alternatively we can supply custom size glass rooflights.

If I am Installing onto a builder upstand, what size do I need to order?

When ordering the Mardome trade polycarbonate rooflight and fitting onto a builder’s up-stand you would order your external kerb to kerb measurement. This rooflight has two different measurements to go by and this is based on whether a customer orders with or without an upstand. Please see our roof light fitting and measurement tab on each product page for more information.

What is U value?

The U value is a measure of heat loss in a structure. It is the amount of heat that flows through one square meter of a material in an hour when there is a temperature difference of one degree Celsius between the inside and outside surfaces. 

The lower the U value, the better the insulation properties of the material.

Polycarbonate rooflights are a good choice for thermal insulation as they have low U values. This means that they will keep the heat in your home, making it more energy efficient. In addition, polycarbonate rooflights are also durable and easy to maintain, making them a popular choice for both commercial and residential buildings.

How do I achieve a better U-Value?

The U value can be improved by selected the polycarbonate roof light glazing levels of polycarbonate sheets. The glazing can be selected from single to quad glazed and the more glazing then the better the U values. We always encourage customers to review their U value requirement to ensure the glazing matches this.
