As we approach 2026, the construction industry is gearing up for the next major overhaul of UK Building Regulations. The Future Homes Standard (FHS) and associated standards will impose stricter targets for energy efficiency, carbon emissions and airtightness. For builders, architects and developers, preparation is no longer optional, it’s critical.
The impending updates to Parts L (Conservation of Fuel & Power) and F (Ventilation) are set to:
These changes will apply to both new builds and large-scale renovations (depending on scope and timing). Falling behind could mean planning refusals or costly remedial works.
With 2026 on the horizon, U-value targets are becoming more demanding: roofs, walls and floors will require more efficient build-ups to meet the new standards.
How TLX Helps: TLX’s multifoil solutions are designed to perform in hybrid systems. By combining products like TLX Silver and TLX Gold with mineral wool or PIR boards, you can hit low U-values without increasing construction depth or sacrificing internal space.
Air leakage and internal moisture control are receiving far greater regulatory focus. Poor detailing or incompatible products will be more likely to trigger inspection failures.
TLX Advantage:
The 2026 regime also encourages materials and systems that minimise embodied carbon and support long-term performance.
TLX Sustainability Credentials:
A developer in Surrey selected TLX Gold for a pitched-roof new build aiming for compliance ahead of the new standards. The system used TLX Gold over rafters plus PIR boards between them. The result: a U-value of 0.13 W/m²K, full head-height preserved and robust condensation control, and the development sailed through building control review.

Unlike bulky traditional insulation boards, TLX products integrate easily into hybrid systems that allow design flexibility and high performance.
Example Hybrid Roof Build-Up:
Choosing the right insulation is only half the job, installation quality, system compatibility and design detailing make the difference. TLX supports you with:
With the 2026 Building Regulations on the horizon, insulation plays a pivotal role in a project’s success. Builders and developers who act now, adopting high-performance, proven systems and robust detailing, will have the edge. TLX Insulation gives you the product performance, the technical support and the system compatibility you need to confidently design and build for the future.
