How does UC 4 differ from standard products? McVeigh Parker UC 4 products are manufactured using only redwoods treated at a moisture content of 28% or less. The solution strength of the preservative is significantly higher than on standard pressure treatments and the vacuum / pressure process is longer and more thorough than standard treatment cycles, allowing for much deeper penetration of the preservative into the timber. Standard non dried pressure treated products have a shorter expected service life, whereas McVeigh Parker UC4 products that are treated against fungal decay and wood destroying insects have a desired service life of 15 years. The entire treatment process is quality assured in accordance with ISO 9001 criteria, and regular sampling and analysis ensures treatment standards are maintained at all times. McVeigh Parker products can also be treated to the National Highways Sector Scheme 4 requirements of a 30 year desired service life on request.
4 main benefits of choosing McVeigh Parker UC 4 products 1. Longer life products – McVeigh Parker UC 4 products are pressure treated to prevent fungal decay and wood destroying insects to give a desired service life of 15 years 2. Peace of mind – When purchasing timber that is to be used in ground contact, why leave it to chance? 3. Value – The majority of cost when installing timber products is usually labour costs. If timber has to be replaced earlier than expected this can be time consuming and costly. Therefore, McVeigh Parker products represent great value for money when considering the whole-life cost of your products. 4. Sustainable – Where possible McVeigh Parker UC 4 products are from FSC Certified sources, meaning they come from well managed sustainable forests.
