Most windows are either inward or outward opening. Whether you choose traditional outward opening designs - developed for harsh climates where wind pressure enhances sealing - or contemporary inward opening styles that offer easier cleaning and larger configurations, every option maintains our uncompromising standards for comfort and energy efficiency.

They were not disappointed. A quality product, delivered well and on time. Thankyou.”

Your Questions Answered

Have a question? You're not alone. We've answered some of the most common questions about our windows range below, drawing from years of expertise helping homeowners and professionals achieve their vision.

Can't find what you're looking for? Email the team.

What are triple-glazed windows?

Triple-glazed windows have units with three panes of glass.

The space between panes is filled with an inert gas – usually argon or krypton – which is a better insulator than air. The insulation, noise reduction and security properties of these windows are significantly better than any single or even double-glazed equivalents.

How thin are triple-glazed windows?

Visual frame widths are 44 to 62mm depending on the window specification. 

Frame depths (inside to out) are 70mm to 128mm, while theglazing unit themselves have (argon-filled) spaces of 16-20mm between glass panes, resulting in a triple pane glass unit that is between 44mm and 52mm thick. 

What types of triple-glazed windows are available?

The majority of windows fall into two basic opening types: Inward opening and Outward opening.

Our range includes both types, available in timber-only or alu-clad timber options and with tilt-and-turn, top hung, side hung or fully reversible hinges. Triangular, circular and semicircular fixed windows are also available. Explore our products with our Window Selector.

How are triple-glazed windows made?

Norrsken’s triple-glazed windows are made from durable engineered timber and clad externally in powder coated aluminium.

Spaces between glass panes are filled with argon gas. Spacer bars, made from low-conductivity plastic, sit between panes at the optimum distance apart to prevent moisture and gas leaks. Multiple seals improve weatherproofing and airtightness.

Why do I get condensation on the exterior of my triple-glazed windows?

External condensation is not a sign that your windows are failing – actually, the opposite is true. In a thermally efficient window, less heat escapes through the window.

The outermost pane drops in temperature, and water vapour in the air then condenses on it. As external conditions change, the condensation will disperse naturally.
