Delivering exceptional thermal performance, the new STII Commercial Door System is an aluminium door system suited to high traffic commercial applications. Offering a range of framing options, installations can be tailored to suit most space and sizes up to three metres high.
Designed for use with Technal’s aluminium window systems and curtain walling, the STII doors provide an integrated façade solution for your projects where high traffic aluminium doors are essential.
Ideal for busy public spaces
Suitable for specification at entrances and exits, the STII commercial aluminium door is thermally efficient, easy to access and operate, resistant to wear and tear and of course, secure - ideal for retail applications, offices, public buildings, schools, hospitals, leisure and residential buildings.
Low U value assists with achieving Target Emissions Rate
Thermally broken, the STII door offers high levels of thermal insulation and can achieve an area weighted U value of 1.8 W/m2K for doors without midrails and 1.9 W/m2K for doors with midrails, depending on size and glazing specification.
When calculating the Building Emissions Rate (BER), this low U value can help building designers to achieve their Target Emissions Rate (TER) by being offset against the allowable U value of 3.5 W/m2K for high traffic doors.
Alternative to Technal PY 55 door system
Introduced as an alternative to the Technal PY 55 aluminium door, the STII Door System features a sleek square cut profile as opposed to mitre cut and also operates on a contemporary pivot basis with a rebated option available, like the traditional rebated aluminium hinged door – PY 55.
