Overview

This primed moisture-resistant MDF windowboard is engineered for internal window installations where durability and finish quality matter. The 25mm x 350mm profile features a bullnosed front edge for a refined appearance and a rebated back edge for secure fixing to the window frame. At 3.05 metres in length, it offers excellent coverage for standard domestic and commercial window openings, reducing the need for joints on most installations.

The moisture-resistant MDF core resists swelling and warping in humid environments, making it suitable for kitchens, bathrooms, and other moisture-prone areas. Pre-primed finish saves preparation time on site and provides a stable base for final decoration. The profile is designed to sit flush with the window frame whilst presenting a clean, professional edge to the room.

Description

Moisture-resistant MDF windowboard combines stability with ease of installation. The bullnosed front edge creates a soft, finished appearance that suits both traditional and contemporary interiors, whilst the rebated back edge ensures a secure, flush fit against the window frame. Pre-priming reduces on-site preparation and allows faster decoration turnaround.

The 3.05 metre length suits most standard window openings without requiring joints, minimising visible seams and reducing installation time. Moisture-resistant core technology prevents the swelling and warping that can occur in kitchens, bathrooms, and other damp environments. The profile accepts paint, stain, or varnish finishes and can be cut, shaped, or routed to suit bespoke requirements.
