External Sunscreen Fabrics

External sunscreen fabric

See our range of external sunscreen fabrics below.

Exterior shading with Helioscreen’s sunscreen fabrics is by far the most efficient way of achieving thermal comfort, giving up to 20% more  solar protection that an interior sunscreen blind. This translates into a noticeably lower ambient temperate inside the home.

Woven in Belgium, the SERGE sunscreen range used for outdoor blinds is eco-friendly, and complies with the Oëko-Tex-100 standard. This means there are no harmful substances present nor heavy-metal content (lead, cadmium, tin). No formaldehyde and allergenic compounds are used, and the yarns are resistant to mould and bacterial growth. The fabric also complies to the latest REACH- standards prescribed by the EU (Registration, Evaluation, Authorisation, and restriction of CHemicals).

SERGE comes in various opennesses and a wide variety of colours, allowing for the perfect amount of heat, glare, and light control for your specific needs.

Helio 86 and Helio 92 are also perfect textile choices for essential solar protection. The fabric makes a significant contribution to building’s heat management by cutting out up to 86% of the sun’s rays, whilst still providing great visibility to the outside.

TV Visible Transmittance

The visible transmittance measures the percentage of visible light coming through the fabric. A low figure shows a very efficient fabric. (The Tv is identical whether the blind is placed inside or outside the building)

OF Openness Factor

The Openness factor measures the proportion of holes in a fabric. This parameter is important to calculate the degree of visibility through the fabric. The Openness Factor is expressed as a percentage. A low OF shows that the fabric is a very close weave. This factor is determined with light rays therefore it varies slightly with the colouring of the fabric.

TS Solar Transmittance

This factor measures the proportion of solar energy transmitted through a fabric. It is expressed as a percentage and for the fabric alone. A low figure indicates a good filtration of solar energy by the fabric.

RS Solar Reflectance

This factor measures the proportion of solar energy reflected by the fabric. It is expressed as a percentage and for the fabric alone. A high figure indicates a good reflection of solar energy by the fabric.

AS Solar Absorbance

This factor measures the proportion of solar energy absorbed by a fabric. It is expressed as a percentage and for the fabric alone. A low figure indicates a low absorption.
