The present invention relates to a method of providing thermal and/or acoustic insulation to a structure, comprising the steps of: providing a substrate which comprises fibres; applying the substrate to the structure; blending the substrate with a binder composition before, during or after application of the substrate to the structure; allowing curing of the binder composition after the substrate and the binder composition have been applied to the structure; wherein the binder composition comprises at least one hydrocolloid. The present invention also relates to an insulated structure obtainable by said method.

The invention relates to an aqueous binder composition for mineral fibers comprising at least one hydrocolloid.

The present invention provides a bamboo strip substrate board and a preparation method thereof, a bamboo strip floor and application thereof. The method for preparing a bamboo strip substrate board provided by the present invention includes the following steps: placing a bamboo strip curtain in a glue-containing solution for glue dipping and draining glue to obtain a glue-containing bamboo strip curtain; drying the glue-containing bamboo strip curtain and then performing assembly to obtain a bamboo strip board blank; and subjecting the bamboo strip board blank to hot pressing to obtain a bamboo strip substrate board. According to the present invention, an outdoor bamboo-based floor is further prepared on the basis of a bamboo strip substrate board. The present invention a simplified preparation process, so the production cost is effectively reduced, and the weather resistance of the floor is improved.
