Thermic lock

T0, T1, T2, T3, T4, T5 en T6 (EN 10077-1 en EN 10077-2)

When doors are installed in a wall separating areas with different functional temperatures, they often need to be thermally insulating.

This especially applies to exterior doors, and the standards for these are becoming increasingly stringent (in Belgium, the maximum is 2.0 W/m² for doors and 1.5 W/m² for windows).

To be classed as thermally insulating, the door’s U-value must be ≤ 3.5 W/m²K and guarantee a minimum airtightness (at least class L2).

Metal+, the basis of every Winlock door!

The distinctive feature of the Metal+ concept is its modularity: each door is characterised by the same sturdy structure, allowing numerous properties and features to be combined in a single interior or exterior door! Regardless of their features, WINLOCK doors always have the same appearance.
They can be finished in top-quality galvanised steel, stainless steel or RAL colour. The separate parts of the door assembly are screwed (not welded), which is possible thanks to the encircling internal frame. This ensures exceptional strength leading to minimal maintenance. After damage or vandalism, parts (such as the hinges or cover plates) can easily be replaced or realigned.
