New homes are under increasing scrutiny from both regulators and homeowners. Design requirements are becoming more complex, and standards are rising for everything from thermal and fire safety performance to environmental impact.
A survey of housebuilders suggests 150mm cavities are becoming the industry norm for new homes, with 41% of participants already having made the switch and just over a quarter considering it.* This shouldn’t be a surprise, as building with narrower wall cavities can limit design options, while 150mm cavities provide flexibility.
Wider cavities allow you to achieve the performance you need with products like DriTherm® Cavity Slab 32, which is:
- Non-combustible, with a Euroclass A1 reaction to fire classification, providing greater peace-of-mind.
- Easier to install correctly, reducing the likelihood of air gaps and enabling real-world thermal performance that lives up to your design.
- Glass mineral wool, which has the lowest levels of embodied carbon of any mainstream insulation material, helping you to deliver lower carbon homes.
Don’t be constrained by 100mm cavities.
Stay flexible with 150mm DriTherm® Cavity Slab 32.
