Silicone and glue in the winter

[Arne999]

I will be building a conservatory in December. All the glue and silicone tubes I've looked at say it should be at least +5 during application. Are there any special options that might work?

Tec7 can withstand the tube freezing without needing to be discarded anyway

They write as follows:
Working temperature +5°C to +40°C (can be applied at sub-zero temperatures but will then only function as a sealant and cure fully at plus temperatures)
