Marmox Multiboard Warms Rutland Cottage

Back

Rutlands Cottage​During the purchase of a delightful cottage in a rural location in Rutland the new owner noticed that the property seemed extremely cold. The main reasons appeared to be the fact that his new home had concrete flooring on the ground floor and solid exterior walls of concrete blocks faced with local stone throughout. To overcome the problem he decided to line the floor and walls with some form of insulation that was effective yet quick and simple to install. After considering the options available he decided that Marmox Multiboard fitted the bill on both counts.

Multiboard is manufactured from extruded polystyrene with both faces of the board covered with close woven fibreglass mesh embedded in a cement polymer mortar. This creates a board that is lightweight yet extremely strong with a high degree of thermal insulation [a conductivity of 0.027 watt/mK for the technically minded] and is totally impervious to any water penetration from outside. This Marmox product is also simple to fix to solid or stud walls being easy to handle due to its light weight and simply cut or sawn to the size required using conventional tools. In the Rutland cottage, 50mm Multiboard was laid on the concrete slab floors. On top was placed a 12mm ply layer and then low level underfloor heating before a surface layer of stone tiles in keeping with the house’s appearance. In the ceiling of the ground floor 10mm Multiboard was applied between the joists. Then, with the floors completed, all the outside walls were insulated internally with 20mm thick Multiboard.

The owner carried out much of the renovation work himself and was delighted with how easy and fast it was to install the Marmox boards. Now all the insulation work is complete he is also impressed with the much improved warmth in his cottage, particularly during the recent cold snap.
