Hi Jack & Jane,
We bought Ikea canopy from UK and was using it last 2 weeks.
It works well for shade but one word of caution you can still get burned under it, all be it slower than in the direct sun, as I found out.
The thermometer on the roof terrace got to 45c. We were talking to some local Spainish and they were saying the June temps are already higher than the normal July / Aug temps, and they are expecting a heatwave up to 50 - 55 in July / August.
Take plenty of factor 50 !!!
