	Do vacuum glazing brands matter?
	Certainly! When it comes to **vacuum insulating glazing (VIG)**, the brand does matter. Let's explore some key points related to VIG and its impact:
	1. **Vacuum Insulating Glazing (VIG)**:
	   - VIG is a type of insulating glazing with an evacuated space between two tempered glass panes.
	   - It achieves high thermal insulation by eliminating heat transfer between the glass panes due to gaseous conduction and convection.
	   - Radiative heat transfer is reduced by one or two internal transparent low-emittance coatings.
	   - The vacuum cavity is thin, resulting in an overall structure thickness only slightly greater than the combined thickness of the glass sheets.
	   - VIG has the potential for high reliability in practical installations due to negligible degradation from gas permeation through the hermetic edge seal.
	2. **Performance and Brands**:
	   - Different brands of VIG may offer varying levels of performance.
	   - One notable brand is **LandVac 8.3mm Vacuum Insulated Glazing**, which delivers U-values (thermal insulation) exceeding those of other options like Pilkington Spacia and AGC FINEO.
	   - LandVac's performance is impressive, with U-values surpassing even solid brick walls, making it suitable for energy-efficient projects like Passiv-Haus.
	3. **Warranty Considerations**:
	   - When it comes to warranty. Please do personally confirm what it covers and what is uncovered.
	   - Due to the quality and stability of the vacuum glazing of different brands, the warranty is not quite the same.
	4.**Installation Considerations**:
	   -Different brands may offer different install services. It is very important to find out who(the brand-led team or a subcontractor) will be responsible for the vacuum glazing installation service. Remember, a good vacuum glazing product requires a good installation team to ensure the best performance.
	In summary, while vacuum insulating glazing itself is essential for energy efficiency, choosing a reputable brand ensures optimal performance and reliability. Brands like LandVac have demonstrated impressive results in terms of performance, warranty and installation.
