¿QUÉ ES EL VALOR R? R significa resistencia al flujo de calor. Cuanto más alto es el valor R, mayor es el poder de aislamiento. A medida que aumenta el valor R, aumenta la eficiencia en la energía.

Aislamiento con revestimientoAyuda a impedir que la humedad entre al hogar. Ideal para áticos sin aislamiento, ni paredes exteriores.

Aislamiento sin revestimientoNo tiene retardador de vapor. Ideal para paredes interiores y para colocar sobre un aislamiento existente.

Bloques de fibra Troquelado para una rápida instalación en pared.

RollosIdeales para espacios sin obstrucciones. Se cortan a la longitud deseada.

Por sopladoEs una forma fácil yrápido de aislar áticos.

DETERMINAR LA CANTIDAD CORRECTA DE BOLSAS REQUERIDAS

¿Se está agregando a aislamiento existente? Use fibra de vidrio sin revestimiento o por soplado.
