Sustainability
A façade that gives back to the city.
A well-insulated envelope cuts energy use and carbon. Reynaers’ recyclable aluminium aligns with Mongolia’s Green Development goals.
Four promises
We build the real value of the spaces people live and work in.
Insulated envelopes cut heating load.
Thermal-bridge-free, high-insulation profiles.
Recycled aluminium, lower embodied carbon.
Robust systems, long-term warranties.
Why it matters
Save energy, breathe cleaner air.
In Ulaanbaatar’s extreme climate, well-insulated windows and façades lower heating costs and emissions while keeping interiors comfortable.
By choosing long-life, recyclable materials and warrantied systems, we reduce a building’s lifetime carbon.


Solar energy
Roof systems ready for solar.
Kalzip standing-seam aluminium roofs take solar panels and rooflights without penetrating the envelope — the roof keeps its full service life and watertightness.
We supply and install Kalzip roof systems on our projects — a roof built today should be ready for tomorrow’s solar.
