Oak Frame Glazing

Often referred to by our customers as one of the most impressive features of an oak frame, glazing allows the ability to have ‘frameless’ windows, thereby increasing the size and aperture of the window, maximising the view. If you’re looking to have an element of the outdoors inside, creating giant picture frames for your surroundings to be enjoyed within the majesty of a timber framed building, then get in touch to tell us your ideas!

These windows can be full height, located on a dwarf wall, or shaped into gables, resulting in beautifully light, bright and airy spaces.

Things To Consider

Things to consider when choosing the most economical route to glazing an oak frame:-

A standard double glazed unit consists of 2x 4mm panes of glass either side of a spacer which is usually 16mm. This spec of double glazed unit is 'comfortable' in sheltered locations, up to a pane width of 1.2m (max) by 2.4mm high.

Larger spans can be achieved by thicker (heavier) 6mm/8mm or 10mm glass - note that the larger and thicker the glass, then the heavier the unit and in turn the installation and overall cost will increase substantially.The typical method of glazing the oak frame will vary to accommodate the extra weight. Get in touch to discuss your plans, and we can give you a more accurate idea of requirements and costs.

You can have too much glass! Be wary of solar gain - a great benefit on a sunny winters day but uncomfortable on a hot summers evening. Solar glare on a ipad or television screen can render these activities void on particularly bright days. Be mindful of the orientation and how you are going to ventilate the space, especially if your glazing is south facing. Your architect will be able to advise you, and a visit to the Carpenter Oak Ltd show barn is recommended giving you the opportunity to appraise the amount of glass in the space.

Performance

A standard double glazed unit using 4mm glass, Argon gas filled cavity will achieve a U value in the region of 1.2. If a sun cool style filter or film is applied to the glass this will marginally improve the U value to 1.1.

Triple glazed is a another keep in cost and weight but does see a marked improvement in the U value to circa 0.7. To give you some perspective a SIPs panelled wall achieves in the region of 0.15 U value!

In context, if you live in an older house a modern oak frame house will be so much more efficient and comfortable regularly surpassing current building regulations. This is probably the hardest net benefit to convey to you at this stage short of it sounding like 'sales speak'!

Peace of mind with Carpenter Oak

You may have heard some horror stories about glazing of oak frames? Rest assured, for over 20 years we've developed an architect and building regulation approved glazing system, which we use again and again without complication.

It is a good idea to have an understanding of the challenges surrounding glazing timber. Green oak, or to that point any timber, can move as it adjusts to the environment it is being used within. Green oak shrinks, twists, and splits, but our skilled carpenters have many years experience to understand this process, ensuring the glazing is extremely successful and dramatic.
