Single or Double Glazed Partition? Start With This Question

We regularly help architects make sure an interior glass partition will perform beautifully for their project. But when we’re asked to help choose between specifying single or double glazing, we often bring the conversation back to one question: what does a ‘full solution’ to solve the acoustic demands of a project look like?

This means we help the client consider the impact of everything involving the partition and affecting sound in their chosen space. By thinking beyond just the glass itself, factors like no return air grills and HVAC penetration are part of the bigger picture for the installation.

This quick read introduction explains how a full solution approach can make sure the acoustic properties of a partition are ideal for every specific location.

The Right Interior Glass Partition

table for soundproofing standards

Choosing between single glazing and double glazing for an interior glass partition is, of course, an important consideration.

However, taking a step back to ask what level of sound isolation is needed and how this will be achieved is by the installation as a whole is the recommended approach.

We strongly suggest…

1. Assessing the present and future need: Understanding the Sound Transmission Class (STC) rating needed, ie the reduction in noise the partition must achieve, is an ideal starting point. Plus, for single glazing systems ask if future double glazing requirements might be a possibility as planning ahead for this flexibility is possible.

Tip: Remember that lab STC scores alone can’t predict the actual performance of a partition in a project as multiple factors will impact sound transmission loss. Plus, remember that MetroWall double glazed systems can be installed as a singled glazed unit, meaning the infill can be replaced and a double glazed system put into place instead if acoustics on-site become an issue.

2. A ‘big picture’ view: Contacting an interior glass wall specialist to make sure every element of the install, not just the glass, works towards the STC goal is an essential. Things like gaps left during construction and HVAC vents will have an impact, which is why we believe in ‘slab to slab’ partitions and assess HVAC’s impact on STC during our design process.

Tip: A poor installation is like putting an IndyCar on rough terrain and expecting race track results! Sound will find a way through a partition if the design or installation allows this to happen. 

3. Look for Experienced Acoustic Partnerships: We’ve worked with leading acoustic consultants – like Cerami & Associates, Longman Lindsey and ARUP – and welcome tests to evidence the performance of the partitions we design, build and install.

Tip: We’re happy to join calls and have meetings with acoustic experts, including your own choice of consultant, and strongly recommend only working with partition suppliers who can show this experience and this willingness to collaborate.

This three-step  approach will ensure your project is asking the right questions and taking the right steps to accurately predict noise transmission performance.
