Modular thermal subframe composed of two or three elements: profile with 25 or 50 mm high rebate flange and a base module for fixing the window frame; both profiles assembled together allow the installation of frames with thicknesses from 53 mm to 68 mm.
Additionally, an extension profile has been created for window frames with thicknesses from 78 mm to 108 mm. The profiles are made from PVC bars, ensuring low thermal conductivity; the conduction coefficient is equivalent to λ = 0.022 W/mK (insulation value approximately double that of an element of the same thickness made of polystyrene).
These accessories are also supplied: a galvanized steel anchoring bracket, a galvanized steel angle bracket for aligning profiles cut at 45°, a galvanized steel joining plate for reuse of offcuts, and a galvanized steel corner stabilizer to maintain right angles during transport.
