Our slimline timber secondary glazing system offers a refined alternative to standard aluminium solutions, ideal for projects where aesthetics are as important as performance. Designed in-house to complement existing joinery, this system features a narrow profile that delivers a sleek, unobtrusive finish—perfect for heritage, commercial or design-led spaces.

Manufactured from high-quality engineered softwood, each unit is fully weather tested for air permeability, watertightness and thermal performance. All seals, glazing and ironmongery are carefully specified to meet strict acoustic, thermal and durability standards.

Spray finished and assembled in our joinery workshop, this system combines craftsmanship with technical precision. It can be fully customised to suit the requirements of any interior, offering a visually sympathetic and high-performing secondary glazing solution.
