Why choose our skylights?
Our polycarbonate circular rooflights comply with the Health and Safety in Roofwork standards.
All of our domes have patented security bolt fixings.
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.
Our polycarbonate skylights have undergone large body impact testing by an independent accredited test organisation and test certificates are available to demonstrate compliance to an energy level of 1200 Joules when tested to pr EN 1873, and ACR(M)001: 2005 to Class B.

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.
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
