Wide Opening Span

Struggling to receive interest in your home from tenants or purchasers? 

Because French doors open widely, there is room for much natural light. This means that your Letchworth home looks bright and lively at all times. 

The doors’ built-in insulation guarantees that your home will stay warm even during the winter season. 

What’s more, our French doors have multiple layers of chambers which give you optimal thermal levels and help you save on energy bills!

Glazing Options

If you are looking to get your hands on optimum quality, our French Doors come in two different glazing options: double and triple. 

This glazing helps keep external noise of up to 31 db outside, ensuring your peace of mind and quiet home life. Just sit back and let us fit the glazing by measuring it to a custom size for you!

Concerned about our French doors’ durability? Rest assured knowing that they regularly undergo tests to ensure their resistance against even the harshest weather elements.

Weatherproof Profile

Do you live in a neighbourhood that is regularly flooded by rain?

Letchworth can be home to intense weather conditions such as rain and snow, and your doors should be prepared to resist it. 

Thanks to a patented bubble gasket by Liniar, an important supplier in the home improvement industry, our French doors are strongly water-proof. 

How does this happen? Well, as the gasket squeezes out to create a large weather seal, it prevents water particles and stops draughts from seeping through.

Low U-values

To make sure your home is retaining as much heat as possible, you want your doors to reflect just that. That is why our French doors are a perfect choice, built with high quality and lead free uPVC that is environmentally friendly and 100% recyclable. 

To assure maximum insulation and savings on energy costs, double glazed French doors contain U values as low as 1.3 while triple glazed windows include U values as low as 1.0.

Low Threshold Option

If you are a homeowner hoping to make your Letchworth property easily accessible to all visitors, low thresholds can help you achieve that.

You’ll find the threshold as the raised step below our French doors, which can be lowered into the floor to make it easier for people with specific accessibility requirements to enter your home.

You can opt to have your French doors fitted with low thresholds of as low as 15mm, which is the right size for families and individuals with prams or wheelchairs.

To guarantee even safer accessibility and prevent any accidents from taking place, you can fit your French doors with Liniar’s 24mm thermally broken threshold that comes with M compliance when installed with a single or double ramp.

Not to mention that you can repurpose and use these French doors to create more updated window profiles in the future, saving more than half the energy that would otherwise be used to manufacture them from scratch!
