Light Transmission

A range of glazing options is available to achieve the required light transmission and thermal insulation whilst a glass glazing option can also improve aesthetics as well as acoustic performance.

All Mardome rooflights are glazed with impact resistant Marlon FSX Longlife polycarbonate, which is 200 times stronger but less than half the weight of glass. Featuring dual sided UV protection, Marlon FSX       prevents up to 98% of damaging UV radiation from penetrating the sheet, protecting occupants beneath the rooflight whilst also ensuring long term weatherability. The outer skin is available in a choice of finishes, Clear, textured, Opal and Bronze.

Thermal Insulation

In order to achieve the required degree of insulation Mardomes are available in single, double, triple and quadruple skin polycarbonate glazed units, each offering progressively better insulation. Part L of the Building Regulations 2013 specify a worst case average  U-value for the rooflight area of 2.2W/m2K and triple skin glazing ensures compliance in both new build and refurbishment applications.

Further options to improve thermal insulation are available. A structured polycarbonate inner option improves insulation very cost effectively whilst an argon filled glass double glazed inner unit not only provides outstanding thermal insulation but improved aesthetics and accoustic performance.

Opening & Ventilation
Opening & Ventilation

It is important to balance the thermal requirements of Part L with those relating to adequate air ventilation, covered by Part F of the Building Regulations to control internal room temperature and maintain a comfortable indoor environment and reducing the risk of mould growth from condensation build up.

Mardome Trade and Ultra offer a range of ventilation options to meet all requirements in domestic and commercial buildings from minimal air circulation through to purge ventilation.

All variants of Mardome Trade and Ultra can be specified with integral trickle ventilation with an option of either "hit and miss" which can be manually opened and closed or automatic humidity controlled which automatically open the vents when humidity beneath the rooflight increases to a given level.
