The expert takes millimetre-precise measurements of the window exposes. They likewise examine for "out-of-square" frames to guarantee the secondary unit will fit perfectly without gaps that might leakage air or sound.
3. Glass and Frame Specification
Based on the needs evaluation, the consultant recommends specific glass types. For example, if noise decrease is the concern, acoustic laminated glass is often suggested. If heat retention is the objective, Low-E (Low Emissivity) glass is the preferred option.
4. Design Matching
The secondary glazing needs to line up with the function of the original window. A vertical sliding sash window typically requires a vertical sliding secondary system so that the initial window remains available for ventilation and cleansing.
Technical Comparisons for Better Decision Making
