What’s the point of impregnation treatment?


As part of our mission to remain the best on the market in both value and quality, we research all our competitors (don’t worry, they do it too). Part of this research is to look closely at terms and conditions, guarantees and various other aspects to see how they compare with our products. During part of this research, I noticed the word ‘Impregnation’ in reference to timber treatment.

The impregnation process, at its most basic, is where the timber (or entire Log Cabin in this company’s case) is immersed in treatment before being air dried and repacked. This process helps guard the Garden Buildings against rot, fungi and insects. Sounds perfect right? Similar to our Pressure treatment? I thought so too but, when I looked closer, I saw text that said that this is not a weatherproof treatment and that a stain or paint would have to be applied after this treatment to truly protect the Log Cabin from the elements. Furthermore, by looking through old blog posts and reading their T & C’s, I found out that you have to annually retreat it with a decent preservative for the guarantee to be effective. This is confusing to me as our pressure treatment needs no additional maintenance. We use pressure treated timber in our Climbing Frames, we provide pressure treated timber as standard with our Garden buildings and have recently released fully pressure treated Log Cabins. These come with a 10 year guarantee against rot and fungal decay, as does this company, but we don’t ask you to annually reapply treatment or even add a preservative/treatment to ensure its protection.

Other companies, such as this one, will claim that they offer Guarantees on their untreated timber. If you take the time to read the small print, and I always advise that you do, you’ll find that these Guarantees are pointless. Why are these Companies offering a Guarantee for something that you are going to have to do yourself?  We don’t offer pointless Guarantees. We guarantee that our pressure treated timber and our galvanised metal will last for 10 years without any additional labour from you.

Another point I found, which not only requires effort but for you to purchase more impregnation fluid, is that they don’t pre-cut their timber. From their videos on YouTube, I found that they give you the large bits of timber and then expect you to cut them to size (the videos I saw featured their tiers of foundation).

Even if you opt for impregnated wood, this will require you to treat the ends as leaving them exposed could result in damp seeping in there. This will require two to three layers of treatment, taking time, effort and money.  All our timber is pre cut to size and planed, including those being pressure treated, so you don’t need to worry about buying additional treatment. Once our Log Cabins are built, they are good to use. Highest quality for minimal effort.
