The Glass Skylight FE Circular offers high levels of wind and rain resistance and has enhanced isothermal characteristics. This results in no condensation whilst achieving maximum energy efficiency and thermal insulation alongside excellent air tightness values. Suitable for flat roof residential and administrative or school building projects the Glass Skylight FE circular is delivered as a fully pre-assembled unit with its GRP upstand, which ensures a quick and easy installation, removing the need to construct difficult circular timber upstands on site.

Features and benefits

Quality

• CE marked quality according to EN 14351 with CE Label product declaration

• Factory production approved to ISO 9001:2015, which means the quality products are manufactured to a consistently high standard

• Fully factory assembled circular skylight - producing a superior quality product that reduces on-site installation time

• Enhanced isothermal characteristics in the overall construction – resulting in achieving maximum energy efficiency and thermal insulation

Design

• Thermally broken aluminium frame free of thermal bridges saving heating costs

• Multi layered double sealing system as standard - which reduces the risk of condensation, mould growth and air leakage

• GRP heat-insulated upstand with seamless silk-white interior finish removes the need of internal plastering

• Circular rooflight delivered pre-assembled to GRP upstand - removing the need for creating timber curved upstands

Comfort

• High daylight incidence with a light Transmittance value of 80% (reference double glazed)

• Effective acoustics and soundproofing with a sound insulation value of Rw,p 38dB (reference double glazed rooflight)

• Excellent U-values supporting whole product efficiency - Utotal 1.2W/m²K and Ug-Value 1.1W/m²K (reference 1000mm)

• Pleasant indoor climate thanks to optional natural ventilation

Use

• Suited for application within residential, commercial and public buildings

• Suitable for flat roof (and roofs up to a 25° pitch inclination) new build or refurbishment building projects

• Improving performance and well-being, due to daylight and ventilation, in sectors including health, office, administrative and education

Design details

Glass Skylight FE Circular technical design characteristics


Energy efficiency

The Glass Skylight FE Circular is the aluminium framed circular shaped glass skylight with maximum energy efficiency and thermal insulation. With high levels of wind and rain resistance, alongside enhanced isothermal characteristics in the overall construction – the unrivalled performance of this range results in no condensation alongside excellent air tightness values. The circular thermally broken “isothermally balanced” aluminium frames feature optimally aligned 10° isotherm line. This means that the thermally broken 10° isothermal line remains within the structure (see diagram) for consistent heat insulation without any weak spots, reducing condensation, mould and bacteria. The Glass Skylight FE Circular also benefits from precision profiles incorporating Thermo Active Design which produces the smooth isothermal lines. TIP Total Insulated Product is certified in accordance with EN ISO 14021.

Performance

•    CE marked quality according to EN 1873
•    Life Cycle Assessment (LCA) to EN 15804
•    Airtight to Class 4, EN 12207
•    Water tightness to Class 4 according to BS EN 12208
•    Wind Load to Class C4, EN 12210
 

Quality control of component manufacture: 

•    Energy management system to EN ISO 50001:2011
•    Quality management system to EN ISO 9001:2015
