Our narrow (250mm) T&G panels will bend up to approx 20cm over 100cm length - along its length. I not sure what way your wall curves but panels would need to be fitted with the curve bending the length of the panels. Another option is to bend the panels along the 250mm width by cutting the into the channels on the back of the panel. 1m wide T&G panels and laminate panels are not possible to bend. Hope this helps - if you need further clarification give me a call.
