Custom Insulation is proud to launch our Custom ThermoSlot product range for the UK construction industry after months of careful preparation.

Slotted board insulation enhances thermal performance, protects against environmental elements, and meets stringent building regulations, offering a comprehensive solution for HVAC systems and mechanical services. Two options are available: a CE-marked PIR solution tested for external use only, and a Phenolic option suitable for both internal and external applications.
Throughout our pre-launch planning we focused on 3 things:
- Time: Deliver finished products from order to dispatch within industry timeframes which are designed for quick and efficient on-site installation.
- Quality: Deliver products to industry quality standards by investing in next-generation slotting machinery, completing extensive production test runs and supplying finished products to pilot projects (we consistently received excellent feedback).
- Cost: Align prices to market norms to offer competitive rates across the product range.

We have been a leader in bespoke, sustainable acoustic and thermal insulation for many years across the white goods, automotive, industrial, and rail sectors. Many projects require tailored solutions and that’s where we come in. We quickly understand requirements, establish the correct specification, source the ideal raw materials from our broad supplier base and manufacture custom solutions. Every piece is shaped, cut, and finished by hand in Burton-upon-Trent, combining traditional craftsmanship with CNC precision.
The launch of Custom ThermoSlot introduces our proven core competencies into the UK construction industry. A high-quality supply chain is in place. Our production and quality processes are industry-leading. Our pricing is aligned to market norms and we’ve built relationships with multiple leading UK Distributors, enabling us to supply Contractors efficiently across the UK from our facilities in central England.
