Velux GPL Top Hung Pine Roof Window
Overview
The VELUX GPL Top Hung Pine Roof Window combines classic timber warmth with modern performance.
Its top-hung opening gives a wide, unobstructed view and excellent ventilation while keeping
the lower part of the frame free — perfect for rooms where you want clear lines and daylight
deep into the space. The smooth, natural pine interior brings a cosy, refined finish that
works equally well in traditional and contemporary interiors.
Design & Finish
Crafted with a durable pine frame, the GPL is finished to a high standard and treated so it
can be painted, stained or left to age naturally. The robust top-hung mechanism makes operation
simple and reliable, while the slim external profile helps maximise glass area so you get more
daylight and a clearer view of the sky.
Glazing Options & Performance
This product is configurable with either double or triple glazing to suit your priorities —
whether your focus is extra thermal efficiency, better sound insulation, or improved energy
performance. Specifically, the 3070 glazing is double-glazed, and the
3066 glazing is triple-glazed. Choose double glazing when you want a great
balance of cost and performance; choose triple glazing where maximum insulation and quieter
interiors are important.
Comfort & Practical Benefits
Top-hung operation allows you to open the window wide without the sash projecting into the
room, so airflow is generous while still being safe for rooms with people moving underneath.
The timber interior helps regulate humidity and provides a warmer feel than cold-frame finishes.
Both glazing options give long-term durability and easy upkeep — wipe clean, check seals
occasionally, and the window should give many years of trouble-free use.
Configuration & Installation Notes
The VELUX GPL is offered in a range of standard sizes and can be installed into new roofs or
as a replacement in many existing openings. When selecting your configuration, remember that
the glazing type (3070 = double, 3066 = triple) affects weight and thermal performance —
installers should be made aware of your chosen glazing so recommended flashings and supports
can be fitted correctly.
Why Choose the GPL?
If you want the character of natural wood with the practical benefits of a modern roof window,
the GPL Top Hung is an excellent pick. It’s a versatile solution for bedrooms, living areas,
loft conversions and any room where you want a clean outlook, easy ventilation and a warm
internal finish. The choice between 3070 (double) and 3066 (triple) glazing gives you flexible
options so you can prioritise cost, comfort or thermal performance.
Frequently Asked Questions
What is the difference between the 3070 and 3066 glazing options?
The key difference is the number of glass layers and the resulting performance. The
3070 option is double glazing — a great all-rounder for energy efficiency and
cost. The 3066 option is triple glazing, offering improved thermal insulation
and better sound reduction. Your choice depends on whether you prioritise lower upfront cost
or higher long-term comfort and energy savings.
Can the VELUX GPL Top Hung Pine Roof Window be installed in an existing roof?
Yes — it can be installed in many existing roof openings and is also suitable for new builds
and loft conversions. Because glazing type affects weight and flashing choice, tell your
installer whether you’ve chosen the 3070 (double) or 3066 (triple) glazing so they can
select the correct fitting kit and ensure a weather-tight installation.
How do I maintain the pine finish and glazing?
Maintenance is straightforward: keep the glass clean with a mild detergent and soft cloth,
inspect seals occasionally, and treat or repaint the pine interior when required to match
your decor. For the external glazing and flashing, ensure gutters and surrounding roof areas
are free from debris to prevent water pooling. Regular checks by a qualified installer can
prolong the life and performance of your window.
