3. Glass and Frame Specification
Based on the needs assessment, the specialist suggests specific glass types. For instance, if noise decrease is the top priority, acoustic laminated glass is typically suggested. If heat retention is the goal, Low-E (Low Emissivity) glass is the preferred option.
4. Design Matching
The Secondary Glazing Traditional Design glazing must align with the function of the initial window. A vertical moving sash window usually needs a vertical sliding secondary unit so that the original window stays accessible for ventilation and cleaning.
Technical Comparisons for Better Decision Making
