Steel is the perfect material for creating high-level security doors systems. Unfortunately, it is also an incredibly aggressive conductor of fluctuating temperatures which provides little insulation against the heat of the summer sun or the cold winter weather.

That is why Premier Security Consultants’ are now able to offer Secured by Design LPS1175 SR2 and LPS 2081 SR2 steel doors that are thermally broken. Thermally broken is where an additional material is integrated within the profile that conducts virtually no heat between the inside and outside frame – thus ensuring that even on the coldest winter days, the heat stays inside and the cold remains out.

Our recent testing with the BRE (Building Research Establishment) makes us the UK’s only manufacturer of LPS1175 SR2 and LPS 2081 SR2 thermally broken steel doors.

In addition to temperature insulation, the thermal barrier also helps ‘dampen’ vibrations between the frames and therefore improving sound insulation.

Many communal entrance steel door systems may have insulated and toughened glass, but what about the rest of the performance? Insulated glass is effective indeed, but depending on the climate, partial insulation may not be enough. The solution? Premier’s thermally broken LPS1175 SR2 and LPS 2081 steel doors. Premier offers a fully insulated door system that can be completely thermally broken with insulated frames in addition to the glass.

Premier’s Vrame Therm system sets new standards in thermal insulation and security. The triple glazing door system can offer the best heat transfer coefficient Ud = 1.1 W/m2K. Thanks to the high-tech insulating bars made from GFK (fibre glass-reinforced plastic), the Vrame Therm door system meets all CE requirements and achieves excellent static values, in numerous tests (air/water/wind/sound/impact/mechanical).
