Double Glazing Installation Guide

Introduction

We have curated a handy guide for when you carry out your next double glazing installation. Depending on where you get your products from, each supplier may have different recommendations.

Why not look at our window and door buying guides to find out the different double glazing products that we offer. Double glazing installation can be a complex job, and we want to make sure that you have all the correct information about your double glazing installation.

How Long Will The Installation Take?

It is hard to give a specific time about how long double glazing installation will take. If you install brand-new double glazing into a new build, it will certainly take a lot less time than removing old glazing and putting new ones in.

By speaking to your manufacturer, you can get specific information about your double glazed doors or windows. We always advise that you assess the property before you mention the timeframe of the double glazing installation.

Tools & Equipment

You need to ensure that you have the correct equipment for your double glazing installation. You will require the following tools before you begin the installation:

• Tape Measure
• Level
• Silicone gun with silicone to match the frame finish
• Foam gun
• Fixing screws
• Screwdriver
• Hammer
• Chisel
• Saw (hand or electric)
• PPC equipment, including safety glasses

Step 1 – Survey

As part of any installation, you should survey the property where you are carrying out the double glazing installation. You can look at any things that may affect the installation of any defects you will need to consider.

During the survey, you will need to take measurements to ensure that you have ordered the correct double glazed window or door. You need to take measurements for the opening and also horizontally.

The final measurements that need to be taken are the smallest height and width; these will be your tightest sizes. This gives the double glazing room to contract and expand when it is adapting against the weather conditions when you fit the tolerances.

Step 2 – Frame Positioning

Before fitting the double glazing, you will need to position the frame within the opening. We suggest using temporary packers or wedges to ensure that the double glazing frame is completely secure in the opening.

Step 3 – Fixing Methods

Different fixing methods may apply to each double glazing installation. We recommend that you get in touch with your supplier to check which fixing system may be the best for your next project. The following fixing options are the most popular.

• Through Frame Fixing
• With Fixing Lugs
• With Polyurethane Foam

Step 4 – Fixing Locations

You can now position the mechanical fixings once you have chosen your fixing method for your double glazing installation. There are several things that you have to consider when carrying out the fixing location. The double glazing fixing must be no less than 150mm and no bigger than 250mm.

Once you have chosen your preferred fixing method, you can now position the mechanical fixings.

After you fix the frame, there may be instances that you need to apply a sealant, especially around the cill area. This will provide protection against unwelcome draughts and cold water. Your customer’s double glazing will then provide their property with structural integrity.

Step 5 – Glazing

Please ensure that the frame is secure before inputting your double glazing. Before any installation, you must also check that the double glazing complies with BS 6161, BS 800-Part 7 and Document L of the Building Regulations.

Step 6 – Finishing and Cleaning

It is important to make sure that you clean up after you have completed the double glazing installation. If there is any debris or excess paint, ensure that you clean it up and dispose of it appropriately.

Step 7 – Frame Sealant

At the end of the double glazing installation, you will need to apply a sealant to the windows. This ensures that there is optimal protection against the weather. Make sure you use a recommended sealant that will work well with your double glazing.

Final Inspection and Handover

Before you hand it over to your customers, do one final inspection to ensure that the double glazing is secure and functioning well. Make sure the area is as clean and tidy as when you arrived and make sure your customers have all the correct information.
