Ideal for use alongside single lap tiles in limited applications, this Corodrain D-Type Universal Valley Trough stands as a narrow valley trough, identified as heavy duty (type: DX). It is equipped with a 35mm sanded strip to enhance mortar adhesion and is used for roofs with pitches ranging from 17.5° to 55°, accommodating a maximum 15° variation between two rafter pitches.
Created with compatibility in mind, this system is tailored for interlocking tiles while remaining adaptable for both natural and manufactured slate usage. It is perfect for prestige buildings and harsh environments and is less susceptible to theft.
Manufactured from GRP, high-quality unfilled polyester resin with glass fibre reinforcement, this trough is grey/blue in colour and at least as durable as lead. It offers high resistance to acid rain and UV light, as well as a smooth finish that restricts debris build-up and the growth of lichen and moss.
