Why choose our skylights?

  • Perimeter screw & seal fixing ensures that the Em-Dome rooflight is completely waterproof.

  • All polycarbonate Em-Domes have a minimum 3 mm thick glazing, the Inner skin thickness does varie according to the size of the dome.

  • Once installed in accordance with the manufacturers' recommendations, Em-Domes can be expected to exceed the life of the roof covering.

  • Our domes have a guarantee against the effects of defective design, construction and material for ten years, subject to certain conditions.

    Polycarbonate skylights are always our recommended choice as these are virtually indestructable, certified "Non fragile" and have a Fire Rating & BBA Certificate available.

    Should I choose Single, Double or Triple skin?

  • Single Glazed - domes are suitable for unheated areas. We always reccomend to specify with caution.

  • Double Glazed - skylights are very economical having a good U-Value of 2.9W/m2k.

  • Triple Glazed - offer the best insulation and complies with virtually all Building Regulations and offer the best sound insulation. U-Value 1.78W/m2k.

  • Upstand

    Upstands are designed to be used in conjunction with our dome rooflights to provide a thermally broken interface which in turn helps to improve the overall thermal efficiency of the roof. Our upstands are insulated PVC and they are excellent value for money. Upstands enhance the overall appearance of the rooflight and are prefinished white internally, therefore requiring no further decoration.


    Due to the nature of the circular upstand, we can't install a manual trickle vent. However, we do offer the circular skylights as an 'opening' unit which can be found under the Opening Domes section.
