Monarch-F triple skin GRP barrel vaults

FILON Monarch-F factory assembled rooflights are designed for use on standing seam and secret fix roofing systems, continuous ridge applications and flat roofs. They are suitable for shallow roof pitches, flat roofs and curved roofs down to a minimum 25m radius.

Tough and durable
FILON Monarch-F rooflights are fabricated from high quality FILON GRP sheets which are robust, shatter resistant and unaffected by extremes of temperature. Long-term surface protection is provided by a UV absorbing film that is applied to the weather surface during manufacture.

Accelerated weather tests by an independent test laboratory
under Clause 5 of BS EN 1013:1-1998 Part1 have classified FILON Monarch-F rooflights as follows:

Clause 5.2: Light Transmission – Category Lo
Clause 5.4 Variation of Yellow Index and Light Transmission after ageing procedure – Classification Ao

These are the highest classifications under this standard.

When used in applications where the rooflights may be subject to mechanical damage, Monarch F rooflights can be specified with extra strong FILON Supasafe top sheets. These rooflights will remain durable and non-fragile for up to 30 years

Out-of-plane design reduces risk of accidents
Monarch F rooflights project above the plane of the roof. This is one of the primary recommendations of the HSE to reduce the risk of persons falling through the rooflight.

Excellent light diffusion
FILON GRP sheet scatters transmitted light, to ensure even light distribution without internal glare or excessive shadows. This makes Monarch-F rooflights ideal for all kinds of applications including areas where natural light is required for working spaces such as factories.

Fire resistant
Monarch-F rooflights comply with the requirements of The Building Regulations for Fire Safety.
