Providing an orangery look and feel
Thermally efficient insulated columns
Super insulated columns will create an orangery style to your conservatory or extension.

The Firmseal process
We pride ourselves on offering the very best experience for our customers throughout every stage of the process.
Known fondly as the “Firmseal experience".
"We had dealt with Firmseal in the past. Came over and looked at showroom, was impressed, staff so helpful, everything went smoothly from start to finish. So nice to get to speak to a person at the end of the phone. Thank you to everyone."
