that is the blog about treating a log cabin
"We give a ten year guarantee on our logs cabins against rot. There’s conditions and they have to be treated regularly blah, blah. If it was up to me I’d give a twenty year one and no treatment. It’s impossible for timber to rot!
Ok, maybe that’s a stupid thing to say, I’ll add a note to it: It’s impossible for timber to rot as long as it is always VENTILATED and allowed to DRY.
So I reckon our guarantee is safe. If you get any rot in 20 years time please let me know and I’ll pay for your replacement out of my own wages. It won’t happen though if she’s allowed to breathe, and, that’s the key with all timber products – ventilation. If it gets wet and it’s allowed to dry out it will NEVER ROT and that’s an inherent property of timber. Not just ours but any timber providing it is
timber of a suitable quality for it’s intended use, especially for log cabins watch out for where the timber comes from, slow gown, cold climate etc."
sounds like the type of place I'd trust with my hard earned

That's the blog post to do with insulation
"If you were one of my customers and you were buying a lovely new
log cabin from me, especially one of our thicker wall log cabins such as 50mm upwards, I would be strongly urging you to insulate at the least the floor of your new log cabin. I would also try to nudge you to insulate the roof as well."
"Lots of retailers supply ‘insulation kits’ with their buildings, we don’t, but we could, we could make a bit of money out of it as well. But seeing as the cabins are costly enough as it is do you really want to add more cost if you can help it. So, instead of me supplying you a special insulation package and making some money from it I’ll tell you how to do it yourself and save money or better still spend the saving on better quality insulation. All the insulation I talk about is ordered through any builders merchant, most of which will deliver to you at the fraction of the cost of a retailers special ‘Insulation pack’."
Again - sounds like the type of place that isn't ripping off it's customers
