At AMS we have the facility of performing all thermal investigations of our systems using the latest heat transfer software from 'Physibel' Belgium. We are an approved and certified thermal simulating facility through the British Fenestration rating council. This enables us to ensure energy efficient systems at an early design stage and also produce accurate project U value calculations for tender submission. System and project U-values are easily calculated with our LogiKal software package which is available to all customers.
