Control the temperature of your space

When it comes to getting the temperature of your home right, there is more to consider than how to heat it on cold days. With hotter summers an ongoing reality, being able to keep our homes comfortably cool during heat waves is a pressing need.

Energy efficiency is another consideration. Good quality windows that offer insulation and an airtight seal, preventing warmth from escaping, will keep heating costs down and ensure your home’s temperature stays consistent and perfectly suited to your needs.

Why you should replace your old roof window

All VELUX roof windows are built to last, but our products improve all the time. Newer VELUX roof windows are built with state-of-the-art insulating technologies that really make a difference. By combining VELUX roof windows with our blackout energy blinds and anti-heat blackout shutters you get even better insulation.

So, if you have been shutting the door to your older renovated room during the cold season, it is time to reclaim your space. Replacing your old roof windows with new energy efficient VELUX roof windows can ensure the warmth stays in, and the cold stays out.
