FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
If you'd prefer crane offloading rather than tail lift vehicle offloading for your brick order then this service is available for the majority of bricks that we sell. Charges are shown at checkout.
For deliveries of less than 6 packs then Taillift offloading is normally a more cost effective option

Trusted Passive Fire Performance
CavGuard Roll 65 by Tenmat is engineered for high-integrity fire stopping in external cavity walls. Its intumescent core activates during fire, expanding to seal off the air gap and limit spread through ventilated cavities.
The roll’s 6mm design allows for continuous ventilation where required and is compatible with uninsulated brick or masonry walls. It reduces the need for cavity trays or weepholes, cutting down build time and complexity.
Designed for Flexible Fit
With a roll length of 6.3m, CavGuard Roll 65 is easy to trim and install. It adapts to site tolerances up to 15mm beyond the standard 50mm cavity, making it suitable for varied construction needs without sacrificing safety.
Easy to Handle and Install
Lightweight and flexible, it can be fitted quickly with minimal tools. The polythene layer ensures safe handling and protects the product before activation. Once in place, no maintenance is needed, making it a cost-efficient solution.
Built for Ventilated Façades
CavGuard Roll 65 supports the airflow needed in ventilated façades, preserving energy performance and minimising the risk of trapped moisture. In case of fire, it seals the cavity while preserving structure for up to 60 minutes.
Backed by Proven Fire Testing
Certified to deliver up to 60 minutes of insulation and integrity, Tenmat’s CavGuard Roll 65 meets the passive fire safety standards required for modern construction. Refer to the manufacturer brochure for full testing data.
