I'm looking to purchase several 'thermal' kennels, as opposed to the more traditional wooden kennels. I have spoken to Premier Animal Housing, and had a good look at what they produce (and am very impressed), but trying to find any comparisons is proving very tricky. I have found only two online (so not seen the product in RL) 'Animal Housing Solutions' and 'Ultra Dog Kennels'

Has anyone here got any recommendations for thermal kennels? Price is also something we need to take into account as we are looking to purchase three maybe four blocks
