Concealed Trickle Vents for An Elegant Look
U-values as low as 1.2W/m2K
Every property is different, but the questions repeat. Here is what Brentwood homeowners ask before choosing Timberlook.
Contact UsVery. The frames are flush rather than stepped, the corners use Timberweld joints that mimic traditional carpentry, and the woodgrain foils carry authentic texture. From the pavement, even trained eyes struggle to tell a Timberlook window from painted timber, which is exactly the point.
Start with what the house already has. Replacing original sashes points to our flush sash range, simpler openings suit flush casements, and a projecting front room calls for a bay or bow. Mixing styles across one Brentwood property is common and works well when colours and hardware match.
Timberweld is the patented method we use to join frame corners. It creates the look of a traditional timber butt joint while welding the frame into a single sealed unit, giving better strength and weather resistance than ordinary uPVC joints.
Very. Multi chambered uPVC profiles trap heat far better than old frames, and the glazing does the rest, delivering U values down to 1.2 W/m2K. Whole house replacements usually transform how a property holds its warmth.
Every window is certified to PAS24, the UK security standard, with multi point locking and fully welded frames as standard. Style does not come at the cost of safety.

Cills
We offer a choice of cill options to enhance your flush sash windows. Choose between the contemporary shallow cill that comes as standard or the Radlington Cill which has been designed to add a sophisticated charm to any property.
These small but strong cills are often used for properties with stone cills, having been crafted to ensure that moisture is directed away from the frames, removing the risk of water ingress.
As the industry’s ‘standard’, these cills protrude 80mm from the front of the frame. They offer long lasting protection, are virtually maintenance free, and come in a choice of colours.
The 180mm cill is the largest cill we offer, protruding 110mm from the front of the frame. You’ll often find these cills in properties with frames that are recessed in the brickwork.
Hardware
As standard, our flush sash windows in Brentwood are equipped with contemporary handles. However, you can customise them further with our Premium Regency furniture. Choose from Peardrop and monkey-tail handles to give your windows in Brentwood a unique, personal touch.
Our sleek window handles fit perfectly with Timberlook windows and won’t interrupt views. They are available in a wide range of colours to perfectly match our windows, and offer smooth and comfortable operation.
