Energy Efficiency

High performance aluminium bifold doors

Contemporary aluminium bi-folds are much more efficient than old steel and aluminium doors thanks to the inclusion of innovative thermal break technology. Contrary to popular belief, modern bifold doors are just as secure and efficient as any other door, retaining optimum amounts of heat and keeping burglars out for decades to come. Warp, fade, and rust-resistant, tough aluminium bifold doors make ideal replacements in buildings located in harsh British coastal areas too. Combined with efficient double glazing or secondary glazing, you can combat rising fuel bills and improve energy efficiency across the board with a high-performance Ventrolla installation.

Once we receive your final payment, our handy ‘Care Pack’ will be sent to you or your client which includes energy improvement certificates for absolute peace of mind.

Maintenance

How do you clean aluminium doors?

Once your aluminium doors are installed, they need very little maintenance to prolong their lifespan. Requiring a quick wipe over with a soft cloth and a mild soapy solution every few months and carefully removing any debris from the track, aluminium is one of the most low-maintenance door materials around.

Once we receive your final payment, our ‘Care Pack’ will be sent to you or your client which includes handy Maintenance Instructions to keep new aluminium doors looking their best for longer.

Frequently Asked Questions

Are aluminium bifold doors thermally efficient?

Modern aluminium doors from Ventrolla feature cutting-edge thermal break technology. Designed to notably reduce heat loss and condensation, unlike old steel and aluminium doors, our robust multi-chambered aluminium frames will not contract or expand in extreme temperatures either.

 

Incredibly thermally efficient and strong, depending on the glazing specified, our aluminium bifold doors can achieve A+ energy ratings with non-insulated, super-insulated & Passive House compliant frames available.

I live in a listed building / conservation area / AONB - can you work on my property?

Quite simply, yes, we can! We have completed lots of work over the years on listed properties and those within conservation areas and Areas Of Outstanding Natural Beauty (AONB). Working closely with local conservation and planning officers, English Heritage, Historic England, Historic Scotland, and Cadw, you can trust in Ventrolla to reinstate and sustain unique architectural features whilst simultaneously heightening historical value too.

Do you offer an installation guarantee?

Yes, our work is guaranteed for 5 years.

Is there a minimum order value?

No there isn’t for our full renovation, draught-proofing, or bespoke new joinery service. However, we can’t usually help with smaller works than this (e.g., broken sash cords, cracked glazing, etc.) unless they form part of a larger renovation project.

How long will the work take to complete?

Varying from area to area, Ventrolla lead times depend on how busy we are, and the specific renovation work required. On average, our lead times range from 6-14 weeks from the date the order is placed. Your Surveyor will be able to advise you further on current lead times, and our operations team will be able to confirm exact timescales once you place your order.

 

PLEASE NOTE: In these unprecedented times, coupled with the latest COVID measures, please be aware that our lead times could be longer than originally specified. Should there be any impact on your installation date, please rest assured we will keep you updated throughout the process.
