Advanced Glazing Solutions
Standard double glazing provides excellent thermal and acoustic insulation for most applications. Advanced specifications with low-E coatings and argon gas filling achieve impressive U-values while reducing energy costs.
Triple glazed sash windows deliver maximum thermal efficiency, ideal for Passivhaus specifications and properties requiring superior insulation. Particularly beneficial for exposed locations and north-facing elevations.
Where listed building constraints prevent window replacement, secondary glazing for sash windows provides effective thermal and acoustic improvement while retaining original windows. Ideal for heritage properties and conservation areas.
- Standard (Annealed Glass): Clear float glass suitable for most applications where safety glazing is not required.
- Safety – Toughened: Heat-treated glass that shatters into small granular pieces if broken. Required in certain locations under building regulations for impact safety.
- Safety – Laminated: Glass bonded with an interlayer that holds fragments together if broken. Provides enhanced security, UV protection, and acoustic performance.
- Acoustic Glass: Specialist laminated glass configurations designed to reduce noise transmission. Ideal for properties near traffic, railways, or other noise sources.
- Solar Control: Coated glass that reduces solar heat gain while maintaining natural light. Helps prevent overheating in south and west-facing rooms.
- Fire Rated: Specialist glazing providing fire resistance for specific applications requiring compartmentation or means of escape compliance.
LandVac glazing provides significant benefits for Scotland, including superior thermal insulation that can lower energy bills, exceptional noise reduction for quieter homes, and its ultra-slim profile is ideal for retrofitting heritage or listed buildings without altering their appearance.
It’s also durable, long-lasting, and helps control condensation, making it a sustainable and reliable choice for improving property performance.
