    Hi all

    I've just installed a floating floor in my garage on top of the existing concrete floor. The wood frame has been laid on a dpm and packed up level as the existing floor slopes. Can I use wool type insulation or should I use solid boards eg. kingspan, coletex. The boards seem expensive and will be awkward to fit tightly as there are a lot of noggings fitted to support the floor level.

    Thanks for your help

    To be honest it would be better to screed the floor to an approximate level, lay board insulation first from wall to wall, then depending on the final flooring boards, either cover with osb to increase the load bearing capacity or board with heavy floor boards, this would provide far better insulation in my opinion...pinenot :)

    The reason I went for the wood floor is because I want the flexibility of having the choice to remove it easily in the future. Also the difference in floor level to the house is just over 100mm. This doesn't leave much for a screed once the insulation has been laid.
