Architectural Profiles Tritherm Spacer System.


APL Tritherm Spacer System is the most technically advanced spacer system available in the UK. As well as providing unequalled thermal properties it is also immensely strong - a combination that maintains structural integrity even with insulation thickness in excess of 300mm. The outstanding structural capacity of the system helps to minimise thermal bridging, permit easy air sealing and at the same time save money compared to 'traditional' detailing.
