Mull Cover System



Table of Contents

The following mulling system does not provide any structural reinforcement that may be required when combining multiple units together. Consult an architect or engineer for design requirements and building code compliance when combining multiple units together.

Furthermore, this system does not function as a water barrier. All water prevention preparations must be put in place prior to installation of the Milgard Mull Cover System.

Guide Overview

3

CriticalDue to mulling multiple units together and framing tolerances, actual dimension will vary from calculated dimensions. Always measure installed windows prior to cutting and fitting components to window/door units. Follow Milgard installation instructions for best results.

The Milgard Mull Cover System is a collection of lineal extrusions and components designed to aesthetically join multiple Essence Series window or door units horizontally, vertically, or both.

This guide will aid in project planning and estimating Mull Cover cut-to-order extrusions and accompanying components. Because of the unlimited combinations of sizes and configurations, this guide focuses on typical arrangements and common scenarios.

All provided scenarios and dimensions are based on typical frame construction. For custom and more complex arrangements, this guide can be used as a reference and deviation may be necessary.

This guide contains the following:Component overview1.Seven step process for dimensioning, configuring and estimating Mull Cover System 2.

componentsTypical scenarios3.Typical terminations4.

For installation please consult Milgard document LA7978 for instructions which can be found online at milgard.com/professional or by contacting your local Milgard dealer

Mull Cover System - Overview



Start Here

Q: Does this system work on all Milgard products?A: The Milgard Mull cover system is only compatible with the Milgard Essence Series® windows and doors.

Q: Does this mull cover system offer any sort of water barrier.A: No. This mull cover system is used solely for an aesthetic purpose. All water barrier measures must be done before the mull cover system is installed.

Q: Will water build up behind the Mull Cover System?A: Water may build up in enclosed locations. In this situation, drilling a 1/8” hole on a bottom, non-visible face will help reduce water build up.

4

General

Q: What materials are the components?A: The extrusions are 6063-T5 aluminum with high performance coating finish and comply with AAMA 2604-10. Plastic components are made of a durable, UV resistant Nylon.

Q: What colors are available?A: Extrusions are available in all Essence colors

Q: What is the longest extrusion length available.A: All extrusions are available up to 16' continuous length.

Components

Installation

Q: Are installation instructions available?A: The Mull Cover Installation Instructions (LA7978) can be found at milgard.com. These particular instructions do not cover the actual window or door installation. Please follow the instructions that come with the unit.

Q: Will parts/components need to be cut or modified at the jobsite?A: Yes. Order components slightly longer than necessary to accommodate minor installation issues. At jobsite, the installer will need to cut components to fit. Modifications may be necessary. In particular the installer will need to rip Cover D (Flange) to the correct width.

Q: What kind of tools will be need for installation?A: A saw and saw blade rated for cutting non-ferrous material, drill for receiver mounting, silicon gun, pliers, and any tool required for window/door installation.
