Description Technical features and measures Tools, guides and downloads

Advantages

DnTw airborne insulation between 55 and 64 dB

L’nTw impact noise level between 58 and 42 dB

Extended Durability

High durability of thermal performance

Avoid risks of interstitial condensation

High vapor diffusion resistance of extruded polystyrene

High resistance to compression

Compatible with installations on the ground, it is unnecessary to cast a layer of padding

Does not need a vapor barrier layer

Installation according to DIT No. 439

Application

Public or private residential buildings on floors that give to non-heated premises or abroad.

Unit of Work

Thermal and acoustic insulation on slab in contact with the outside air formed by:
DANOPREN® TR extruded polystyrene panels, 40 mm thick, with mid-wood perimeter joints, deposited on the slab and protected by acoustic sheet of cross-linked polyethylene and foamed closed cell, 5mm thick, IMPACTODAN® 5, sealed with self-adhesive cross-linked polyethylene tape of 3 mm thick, 70 Overlap tape (Cinta de Solape), mortar at least 5 cm thick separated from the structure and installations by using Peripheral band tape (Desolidarizador Perimetral); ready to install ceramic tiles.
Installation system according to D.I.T. 439R / 16.
