Single glazed or double glazed internal doors – which is better for your home?

When it comes to choosing interior steel look doors for your home, one choice you will need to make is whether to have these single glazed or double glazed. Whilst most interior doors come single glazed, both options have their advantages, so it is essential to consider your needs and preferences before deciding. This article will explore the differences between single and double glazed interior doors to help you make an informed decision.

Single glazed or double glazed internal doors – why it matters

For most properties, the single-glazed option is widely used for internal doors and a professional installer will always provide safety glass, laminated or toughened as standard.

However, when choosing between single glazed or double glazed, your key considerations are how you use your doors, the room they are in, and other individual requirements relating to your home layout and use generally.

Double-glazed units come as standard for all our exterior windows and doors because these windows must provide the right insulation and energy efficiency to meet Building Regulations and provide you with a more comfortable home as well. Double glass also offers an extra barrier to glass security. Interior doors don’t usually need insulation, enhanced security or weather protection, so single glass is commonly used.

Therefore the main reasons to go with double glazing is better insulation, even if inside and helping keep your rooms quieter with the improved noise reduction double glass provides.

What is Single Glazed Interior Door?

Single glazed interior doors are doors that have a single pane of glass. For our doors, we use a variety of glass thicknesses to suit the application.

Single glazed doors will cost a little less than double glazed and you’ll also find them slightly lighter because there is one less pane of glass.

What is Double Glazed Interior Door?

On the other hand, double-glazed interior doors have two panes of glass with a space in between, hermetically sealed with optional argon or krypton gas. Typically the glass units are between 24mm and 28mm thick. Visually, the glass unit spacer bar is visible or more prominent on double-glazed doors, and you are looking through two glass panes. You will always have slightly more weight to the doors because of the extra glass pane.

Factors to Consider When Choosing between Single and Double Glazed Interior Doors

There are several reasons why when choosing single glazed or double glazed internal doors, the double glass option can provide a better solution.

You need quieter rooms

With many people working from home, getting a quiet space to work is very important. Double-glazed doors do provide that extra barrier of sound insulation. Even better, you can get acoustic glass units specifically designed for sound insulation, making the performance even better than standard 24mm or 28mm glass units. Typically these comprise a thicker pane of glass on the inside of the door than on the outside.

Therefore if working in a quieter room whilst enjoying the benefits of an Aluco interior door or screen is desirable, choose the double-glazed option.

Better insulation with double glass units

Whichever way you look at it, double glass always provides better insulation than single glass. Perhaps you are fitting our steel look internal doors in your hallway or other large room? The double glass will provide an improved door, but do bear in mind our internal doors do not come with insulated frames, although we can provide our exterior single or double doors internally if required.

You want even better glass security

Single toughened or laminated glass is already strong and safe for internal doors and for family living. But if you do decide to go with double-glazed doors, both sheets of glass are safety glass, giving you added peace of mind.

A better aesthetic with single glass

Single glass can provide a more minimalist and neater design aesthetic than double glass because the double-glazed unit spacer bar can be visible, even in black. Therefore, single glass always looks neater and sleeker. And do bear in mind, enhanced security laminated glass is available with single-glazed doors and screens. Single glass looks better when choosing a patterned design too.

Single glazed or double glazed interior doors – conclusion

In conclusion, when choosing between single glazed or double glazed, both interior doors have advantages and disadvantages. Ultimately, the decision will depend on your needs, preferences, and budget. Double-glazed doors may be the better option if you prioritise sound insulation and better glass insulation generally. However, if you want to save money and prefer a simpler design, single-glazed doors may be the best choice for your home. Whatever option you choose, you are guaranteed fully compliant doors in terms of glass quality and safety.

Just completed house renovation, using all the internal bespoke doors with glass panels. Absolutely delighted with the quality of doors and service. I was assisted every step of the way in getting the right size and format of extremely tall door. Keiran has been exceptionally helpful to deal with over the months from ordering to completion. 10/10I never usually do reviews but but I would say the whole experience and end result that has been achieved has been amazing.

So pleased with our new Aluco bifold doors, the best we could find on the market! We wanted bifolds with maximum glass area and no bulky frame and the Aluco doors were the perfect choice. Stunning, deep matte black colour, high quality, great choice of hardware and a first-class service. Highly recommend!

I recently had 3 sets of ALUCO exterior crital styled steel framed doors fitted to my property as part of an ongoing renovation. After looking around at various options Aluco was the only manufacturer that I felt could deliver the style I was looking for. With most other companies I thought the design was bulky and not finished to the finesse Aluco has achieved . Based on my experience I can honestly thoroughly recommend this manufacturer and will look to use them again on any future projects
