Meeting Rails: This is when the highest and base sashes overlap. Even a 1–2mm gap below can allow cold air to snake through, In particular on windy evenings.Increased Safety: Fashionable acrylic panels or toughened glass insert an internal barrier, deterring pressured entry.Condensation Command: By equalising interior temperature, secondary glazi

Good thermal insulation reduces the necessity for excessive heating and cooling, thereby reducing energy intake and decreasing greenhouse gas emissions.2. Noise Reduction Gains: Secondary glazing also serves as an efficient solution for minimising exterior noise air pollution. Regardless of whether you live in close proximity to a active street, ai
