Who this guide is for
- Homeowners sensitive to smells from new materials
- People renovating and introducing many new finishes
- Anyone planning material choices with air quality in mind
- Renovators wanting context on low-emission options
What VOCs and off-gassing are
VOCs are compounds that can evaporate from certain materials at room temperature. Off-gassing describes that release, which is often strongest when a material is new and tends to lessen over time as the material cures or airs out.
Recognising which categories of product commonly emit them helps you plan.
- VOCs can be released from some materials as gases
- Off-gassing is often strongest when materials are new
- Emissions generally reduce over time
- Paints, adhesives, boards and furnishings are common sources
Why awareness matters during renovation
A renovation can introduce many new materials in a short period, which is when off-gassing is most concentrated. Being aware lets you consider lower-emission options and plan how to air the space.
Awareness turns a vague unease about new-material smell into specific, manageable choices.
Material choices and labels
Many product ranges describe their emission levels, and choosing lower-emission options where available is one planning lever. Reading product information and asking suppliers helps you compare.
Labels and supplier guidance are more reliable than assumptions about any product.
Ventilation as part of the picture
Good ventilation helps disperse emissions, so material choice and ventilation are best considered together. Airing newly finished spaces is a common-sense complement to lower-emission materials.
How best to ventilate a specific space is something a professional can advise on.

Common mistakes to avoid
- Ignoring material emissions when many products arrive at once
- Assuming all products in a category emit the same amount
- Overlooking ventilation when choosing materials
- Relying on assumptions rather than product information
- Treating new-material smell as something to simply endure
- Expecting this page to provide medical or safety advice
When to involve a professional

- Follow product guidance, which varies by material
Frequently asked questions
Questions readers ask about this topic
What does off-gassing mean?
It describes the release of volatile organic compounds as gases from some materials, often most noticeable when they are new. The release generally lessens over time as materials cure or air out, which is why awareness during a renovation is useful.
Which materials commonly off-gas?
Categories such as some paints, adhesives, boards and furnishings are common sources, though emission levels vary widely between products. Reading product information and asking suppliers is more reliable than assuming any product behaves a certain way.
How can I reduce exposure during a renovation?
Common planning levers include choosing lower-emission options where available and ventilating newly finished spaces well. Material choice and ventilation work best considered together; a professional can advise on ventilation for your space.
Is this a health guide?
No. This is awareness and planning content with no health claims. If you have specific health concerns, consult a suitably qualified professional, and always follow the guidance provided with each material.
