Glass makes the space bright, quiet, and safe — if it is properly selected and installed. Poor specifications or compromised installation in glazing services can cost double: condensation, noise, heat loss, cracks, and repeated repairs. This guide gathers practical advice for choosing double glazing, tempered and laminated glass, glazing a terrace, as well as how to request a quality replacement of double glazing or custom mirrors.
1) Which glass is for what?
• Insulated glass unit – two or three panes of glass with a spacer and gas (often argon). A good choice for residential windows/doors. The combination of Low-E + warm spacer reduces heat loss and condensation.
• Tempered glass – 4–10 times stronger than regular glass; suitable for shower cabins, partitions, doors, countertops. When broken, it shatters into small pieces with a lower risk.
• Laminated glass – two layers with an interlayer (PVB/EVA). Provides security and sound insulation, holds pieces together upon impact; recommended for railings, showcases, and glazing of elevated terraces.
2) Symptoms that it's time for a replacement or repair
• Appearance of condensation inside the double-glazed unit – compromised seal.
• Cold draft around the frames, noise from the street, "foggy" appearance – need for replacement of the glass unit or proper framing/sealing.
• Cracking, sagging of the door/partition, rattling – possible issues with installation/hardware.
• Sun glare and overheating – consider solar/selective glass.

3) Glazing a terrace: comfort in all seasons
Glazing a terrace with a quality double-glazed unit improves energy efficiency and sound insulation. For safety at height, add laminated glass or tempered + lamination depending on the project. The correct profile, drainage, and ventilation (micro-ventilation) are important to prevent condensation.
Myth / Fact
Myth: "The thicker the glass, the quieter and warmer it is."
Fact: The construction of the glazing unit (number of chambers, spacer, Low-E/solar coatings) and the installation are more important than "just thickness."
4) Custom mirrors and interior solutions
Custom mirrors with polished edges and concealed fasteners work wonders in bathrooms, hallways, and fitness areas. For wet rooms, order a mirror with a moisture-resistant backing and suitable silicone. For kitchens – tempered glass as a backsplash above the countertop, easy to clean and heat resistant.
5) How to compare offers – without falling into traps
Request a clear specification: type of glass (Low-E/solar/matte), thicknesses and combinations, spacer (aluminum/"warm"), gas (argon/kripton), type of tempering/lamination, type of edging and installation, silicones and seals, waste disposal, warranty. Compare not only the price but also the timeline, material brands, and included adjustments.

6) Common Mistakes and How to Avoid Them
• "We will use regular glass." In areas with risk/load, require tempered or laminated glass.
• Lack of drainage and ventilation when glazing a terrace – a guarantee for condensation and mold.
• Inaccurate dimensions – the size is always adjusted on-site by the glazier/installer.
• Weak installation – foam ≠ only fastening. Look for the right fasteners, spacers, professional tools.
• No warranty – request a written warranty for glass services and installation.
7) The process in brief: from request to completed project
1. You describe the need (window/door/terrace/shower/mirror), photos, and size references.
2. You receive 2–3 personalized offers with option A/B (for example: double versus triple glazing).
3. On-site inspection and final dimensions, clarification on access and preparation.
4. Fabrication and installation – edge, joint, and seal control; functionality testing.
5. Acceptance and warranty, maintenance instructions (cleaning, ventilation, condensation control).
8) How long does it take and what does the budget depend on
The timelines vary depending on the scope: a single replacement of a glazing unit often fits into one visit, but comprehensive glazing of a terrace requires inspection, fabrication, and installation in phases. The budget depends on the type of glass (Low-E/solar/tempered/laminated), dimensions, hardware, complexity of access, and warranty conditions. A small upgrade (warm spacer, better sealing) has a significant effect on condensation and energy costs.
Conclusion: light, silence, safety
Properly selected and installed glazing services provide silence, lower bills, and an elegant finish — without condensation and unnecessary repairs. Start with a clear specification, compare offers, and choose a verified team; this way, you invest once and benefit for years.
