LBS flush-faced steel doors are the perfect fit and perfect finish for both internal and external doorways with a complete range of locking, glazing, infill panels, and louvre options as required.
Made of high tensile steel for a stronger yet lighter door complete with an insulated core for improved thermal properties and incorporating a full height anti-jemmy security astragal.
Constructed from Zintec, galvanised or stainless steel with full polyester powder-coat colour finishes available.
Our thermal steel door has achieved an industry-leading U-Value of 1.6 W/m²K when assessed under EN ISO 10077-2; 2012 and 10077-1;2006 in both single and double door configurations, exceeding thermal energy efficiency standards referred to in Part L Building Regulations guidelines, which require external pedestrian doors to achieve a U-Value under 2.2 W/m²K.
On average up to 20% of heat loss is due to poorly insulated doors and windows. Our advanced thermal technology will contribute to the energy efficiency of buildings as well as saving the bill payer money.
