Which wall thickness and cabin specification is best for you?
Insulating the roof and floor of a single skin cabin dramatically improves their usability (warmer in the winter and cooler in the summer), but a Twin Skin is far superior. The table below shows the values achieved with Hortons log cabins (the lower the U value, the better it is).

Choose your own design
Don't forget that we can modify this cabin to look and feel however you like. In fact, you can tailor all Hortons log cabin kits to your specific needs. Yes, you can actively participate in designing your own garden room. Alternatively, We can also design a cabin based on your existing designs. If you have already drawn up (or by your architect), then we can build your cabin according to these as well. There are no limits, so it doesn't have to be a pent roof design, for example.
Modern styling of the pent cabin
Contemporary log cabin designs, such as our 6x4m Lancing pent cabin, are now simpler. Being more clear-cut than those used in traditional log cabins. Pent roofs, low pitch roofs and flat roofs are gaining in popularity. Our contemporary pent cabins also incorporate some of the latest trends in modern cabin design. Utilising large panoramic windows for example. Combine this with wide open internal areas gives you a wonderful garden room.
Pent roof cabins need reliable roofing
The modern popularity of the low pitch pent roof has come about in no small part because of the new type of roofing material - EPDM rubber roofing. The main reason for the historic hesitancy of customers regarding the pent roof (or slightly sloping flat roof) is that they have a felt covering. Felt only comes in 1m wide rolls, and therefore there were numerous joints across a roof span. This 6x4m pent roof would have 5 joints totalling a 30m run of seam. It only takes 1 weak joint to start leaking and you've got a major problem.
Felt only has a finite life span. So unfortunately it is always a ticking time bomb and it will always inevitably leak. EPDM however has a much longer life span - ours has a 20 year manufacturer's warranty. And will last much longer than that, and crucially is one large sheet. This eliminates the problems that felt roofs have.
