We understand the needs of our customers and have established an excellent reputation for consistently delivering quality products aligned with industry leading next day service.

Timloc Building Products range:


Adapt-Air is the pre-assembled ducting to airbrick adapter set from Timloc helping to meet Building Regulation Part F.

The cost-effective ducting to airbrick adapter kit is delivered pre-assembled, ready to fit straight out of the box – it saves time, reduces costs and minimises the need for external fitters, core drilling and specialist tools, when connecting to an internal fan to duct through to an external wall. Adapt-Air has been designed to be built in as part of the brickwork package and terminates at an external airbrick, removing the need to use unsightly gravity flap vents and avoiding the unsightly re-works of cutting a hole through brickwork.

Cavity trays

At Timloc, we offer a wide range of preformed leaded and unleaded cavity trays to meet almost any application requirement and type of masonry. We also have a wealth of experience in designing and manufacturing non-standard cavity trays for project requirements.

Hedgehog Highway

As part of our continued sustainability efforts, Timloc Building Products has produced a hedgehog highway to help tackle the declining number of hedgehogs across the UK.

The Hedgehog Highway by Timloc has been designed to connect gardens, enabling hedgehogs to roam freely and forage for food and shelter without restriction.

As a manufacturing company, we take our responsibility for the environment seriously and the conservation of hedgehogs is a matter close to our hearts. The Hedgehog Highway by Timloc is produced from 100% recycled plastic – as is 75% of the Timloc product range – and the packaging is 100% recyclable too. A donation from the sale of each Hedgehog Highway by Timloc will be made to hedgehog rescue centres and support organisations across the UK.
