Meet the Hallmax PRO: A Premium Double / Twin Rebate 70mm Composite Door Upgrade If you’re looking for the next level in composite door performance

The increased slab thickness — 70mm compared to the standard 44mm — not only improves thermal efficiency but also gives the door a more solid, secure and premium feel.
