The science of
frame, glass, & seal.
Cadence designs and tests architectural openings for ambitious buildings — measured to four decimals, certified to five standards, detailed to the millimetre.
Four numbers that
describe the wall.

Cross-section,
at full scale.
Each Cadence frame is a four-layer assembly: a quarter-sawn oak (or aluminium) carrier, a thermally-broken Argon cavity, a triple-glazed low-iron IGU, and a three-pass EPDM seal at the perimeter.
The result is a wall-equivalent thermal performance with the optical clarity of single glazing — and the acoustic profile of a much thicker assembly.
