Optimum performance

Optima is one the most energy-efficient 70mm systems available. Its brilliance lies in the adaptable nature of the system. Its components and options allow the fabrication of windows that perform to your required standards. Customers with exceptional levels of insulation in their homes can opt for the ultimate triple-glazed frames. Others, working to a budget, can improve their insulation without breaking the bank. It’s simply a case of building the performance you want. Of course, Building Regulations dictate minimum standards, but it’s worth knowing that Optima can easily achieve the very top end of the energy-efficiency scale. It can reach the latest A++ WERs and a remarkable U-value of just 0.8 W/m2K. That’s the Passivhaus standard.
