Technical Performance

InShade sails were developed specifically to deal with the high temperatures and humidity that can be found in UK conservatories. Our stretch fabric has been selected after 6 years of site trials and extensive lab testing for its unrivalled ability to resist UV degradation. Every batch of fabric is tested to ensure our high standards are maintained and every sail is backed by our 5 year warranty.

InShade 100 fabric construction is 83% IFR Polyester and 17% Elastane.


Every batch of fabric is tested to confirm conformity to the British standards and ensure that your sails will provide many years of enjoyment.
