Fully Insulated Log Cabins - Top Features To Look Out For

If you are planning to use your garden building all year round, you want a high quality log cabin that you can use whatever the weather conditions. 


Purchasing a log cabin is already a hard decision, nevertheless choosing the extra aspects such as the insulation. To make this process as easy as possible, we want to provide you with a handful of features to look out for whilst shopping for your insulated garden room. 


Ask yourself… 


  1. What material is being used to insulate the log cabin? 


To insulate our log cabins, we use one of the best insulators available - Polyisocyanurate. A material that is known to be lightweight, versatile but what makes it so sought after is its high thermal conductivity. 


A little fun fact for you. It has been said that even NASA has used Polyisocyanurate in their spacecraft! 


During your hunt, you may come across other insulation materials such: rockwool, polystyrene or aluminum bubble wrap. These forms of insulators are much lower quality, therefore making the cost of the overall garden room cheaper. 


  1. What is the insulated wall thickness?


Our Warmalog design is a fully insulated log cabin with walls that are 62mm thick, which is equivalent to a 140mm thickness without insulation. The beauty of having the thinner walls which are insulated, is that you do not lose the space internally. Each full length log comes with a triple tongue and groove, giving you a deeper, more flushed, interlock.

  1. Do I need to purchase the roof and floor as an addition to the log cabin? Is the roof and floor insulated? 


All our insulated and non-insulated log cabins come with the roof and floor included at no extra cost. Many others may charge you extra for this, and some features included in our packs are not provided at all, such as storm braces.

On our Warmalog cabins, you will find that the roof and floor are also fully insulated. The roof is 60mm and the floor is 50mm thick. You can’t get any cosier than that! The cabin will be warm in the winter (with the help of a heat source) and cool in the summer.

  1. Do I need to fit the insulation myself?


In order to make your construction experience as simple as possible, there is no need to fit in the insulation yourself. The polyisocyanurate has already been sandwiched between the timber, helping you to get it up and running quicker and easier. 



  1. What is the log cabin made of?


All our garden buildings are made from slow grown spruce timber, providing you with a more durable and long-lasting log cabin. This high quality timber means fewer knots, cracks, warping and leaking sap. 




  1. What type of glass is used on the windows? Are the windows double glazed?


The windows and doors on all our log cabins feature toughened glass, which is safer than standard glass as it crumbles when broken. All our insulated log cabins come with 24mm thick double glazed windows, even on the double french doors. Another feature that keeps the warmth inside your log cabin during the winter.
