Ventilation Megastore

Ventilation Megastore is dedicated to improving energy efficiency by the use of mechanical ventilation heat recovery systems. 

These devices ensure that indoor environments have fresh, clean air preventing condensation whilst maintaining a comfortable temperature and helping everyone to remain healthy. 

MVHR (Mechanical Ventilation with Heat Recovery) systems provide filtered air into a building while also maintaining internal temperatures - meaning that you don’t have to open your windows and let heat out to ventilate your home or business premises. 

Our industry experts at Ventilation Megastore are able to tailor products to your specific requirements, supplying everything that you’ll need for a straightforward, quick installation.

Cork is a natural insulator that is durable and long-lasting, ensuring that your floors will look good as new in years to come.
