Our STAKI TOP-LAG Flooring has been cleverly manufactured to give the stability of an engineered board but is made up of 100% solid oak which keeps the wood expansion to a minimum. This unique design means that this solid oak floor is perfectly suitable for underfloor heating. Must be installed stuck down.
The two oak layers are glued in the cold way using EPI glue, which meets resistance class D4 according to EN204. The top layer of TOP-LAG wooden flooring is 6 mm oak, for this reason the operational period is much longer than many others parquet with the same thickness. The bottom layer oak has a finger jointed construction to allow heat to easily pass through the floor. TOP-LAG is a tongue and groove board, dimensions are 14 x 180 x 500-2450mm. It is 2 bevelled along the sides and is rustic grade.
TOP-LAG is available in 14 colours, see products below. Please allow a 6 weeks lead time for TOP-LAG colours. Some of our products are smoked which can cause colour variation between the boards. We recommend sticking this product down to the subfloor using Taurus H22 adhesive which is a flexible silane adhesive used to stick down engineered and solid wood flooring and is also suitable for underfloor heating (up to 27 degrees).
TOP-LAG wooden flooring thermal conductivity coefficient λ = 0,15 W/m2K. Therefore, we recommend these flooring installed on the heated base. However, the heated floor surface temperature can not exceed 30 ° C.
